Answer:
Respiration in plants: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. ... As with photosynthesis, plants get oxygen from the air through the stomata.
Transpiration in plants: The water eventually is released to the atmosphere as vapour via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

Which of the following chemical reactions is most likely to have the largest equilibrium constant K?
A. CH3COOH(aq) + H2O(l) CH3COO- (aq) + H3O+(aq)
B. HCl(aq) + H2O(l) H3O+(aq) + Cl-(aq)
C. H3PO4(aq) + NH3(aq) H2PO4-(aq) + NH4+(aq)
D. CH3COO- (aq) + H2O(l) CH3COOH(aq) + OH-(aq)
Answer:
The answer to this question is HCl(aq) + H2O(l) = H3O+(aq) + Cl-(aq). HCl is considered a strong acid meaning it is 100% ionized in solution. The equilibrium constant is therefore very large.

22 Determine the molar mass of an unknown gas that has a volume of 72.5 mL at a temperature of 68C, and a pressure of 0.980 atm and a mass of 0.207 g.
Answer:
81.5g/mol
Explanation:
Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.
To solve this question we must find the moles of the gas in order to obtain the molar mass using:
PV = nRT
PV / RT = n
Where P is pressure = 0.980atm
V is volume in Liters = 0.0725L
R is gas constant = 0.082atmL/molK
T is absolute temperature = 68°C + 273.15 = 341.15K
0.980atm*0.0725L / 0.082atmL/molK*341.15K = n
2.54x10⁻³ moles = n
Thus, the molar mass of the gas is:
0.207g / 2.54x10⁻³ moles

However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

answer choices
2.41cm
2.41 x 10^4cm
2.41 x 10^-2cm
2.41 x 10^-6cm
Answer:
2.41*10² m equals 2.41*10⁴ cm
Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{c*b}{a}[/tex]
In this case the rule of three can be applied as follows: if 1 m equals 100 cm, 2.41*10² m equals how many cm?
[tex]cm=\frac{2.41*10^{2} m*100 cm}{1 m}[/tex]
cm= 24100 = 2.41*10⁴
2.41*10² m equals 2.41*10⁴ cm
Match the different methods used for calculating revenue and profit to the formulas used for calculating them. total revenue average revenue marginal revenue gross profit net profit
Answer:
See explanation below
Explanation:
1) Total Revenue:
Total revenue refers to the total amount of income that is generated when a company sells or offers their service.
It is usually calculated as the product of the product or services sold by the quantity.
It is calculated by ;
TR = Q * P
Where TR = Total Revenue
Q = Quantity
P = Price
2.) Average Revenue:
Average revenue is the revenue gotten by a company per unit of output sold. It is calculated by:
AR = TR / Q
Where AR = Average Revenue
TR = Total Revenue
Q. = Quantity
3.) Marginal Revenue:
This is the net revenue that is generated by selling an additional unit of commodity; which is the change in total revealer unit. It is calculated by:
MR = change in Total Revenue / change in Quantity
Where MR = Marginal Revenue
4.) Gross Profit:
Gross profit is the amount of revenue left after factoring out the cost of production and sales and servicing.
It is calculated by subtracting revenue from the cost of goods sold -
Gross Profit = Revenue - Cost of goods sold
Net Profit:
Net profit is the amount of money a company has left after subtracting all interests, tax expenses and cost.
It is calculated by;
Net Profit = Gross Profit - Expenses

Suppose you have 1000 lb of waste copper (II) oxide sitting in the basement of your factory. Do you see a problem with sending it to a landfill?
Answer:
Yes.
Explanation:
Yes, we have a problem with sending it to a landfill of copper oxide because it has harmful effect on the health of humans as well as more weight of the copper oxide. Copper oxide usually found in powder form which can easily be inhaled that causes death of the cell due to toxic effect on the mitochondria and lysosomes of the cell. It makes problem of health in carrying the copper oxide from the basement of the factory to the landfill region due to its power form so we can say that it can do problems to human health while carrying from one place to another.

Why are different detergents made for cleaning different surfaces and how their chemical structure/composition affects this?
Answer: This is because of the different chemical composition of the types of detergents affects their cleansing actions.
Explanation:
Detergent means any substance which has the ability to clean an object. This includes soaps, soap powers and dish washing liquids as well as water. Detergents fall into two main types
--> Soapy detergents and
--> Soapless detergents
Soapy detergents are sodium salts of fatty acids. They are saponification products of fats and oils. In the chemical composition, each molecule of soap possesses a long hydrocarbon chain attached to an ionic head. The hydrocarbon tail is hydrophobic, so it is insoluble in water but soluble in oil and organic solvents. The ionic head is hydrophilic, so it is soluble in water. Due to this dual nature, when is dissolved in water, the soap molecule forms spherical clusters called MICELLES( hydrocarbon tails points inward and ionic heads point outward). Repulsion between the similarly charged ionic heads keeps the micelles apart. This property helps the soapy detergent to lift grease from grease coated fabrics when applied to it.
While the chemical properties of the Soapless detergents has a hydrophobic tail and a hydrophilic head. The hydrophobic tail is either a long chain hydrocarbon or a benzene ring with a long alkyl group attached. The hydrophilic head, unlike the Soapy detergents, can be positively or negatively charged or even neutral. These chemical properties makes it to have a more favourable and wider application than soapy detergent.it is suitable for washing acid - sensitive fabrics and for breaking up oil slicks.

A solution of 12M HCl is diluted so that it goes from 550mL to a total volume of 1000mL. What is the new concentration of the solution?
Answer:
6.6M
Explanation:
C=concentration
V=Volume
C1V1=C2V2
rearrange formula to find C2
(C1V1)/V2= C2
(12M x 550mL)/1000mL= C2
6600M*mL*/1000*mL* =C2 (cancel units)
6.6M=C2

What would be the effect on this reaction of increasing the temperature?
2H2 + O2 = 2H20 + energy
A) the rate of formation of H2O would increase
B) The forward reaction would be favored
C) Increasing the temperature would not have an effect on this reaction
D) The rate of the forward reaction would decrease
Answer:
D) The rate of the forward reaction would decrease
Explanation:
The statement that describes effect on the reaction of increasing the temperature is "the rate of the forward reaction would decrease."
What is temperature?Temperature is the measurement of a body's level of hotness or coolness.
The average kinetic energy of the system is measured by temperature. The kinetic energy of particles in a matter raises as they move faster, which boosts the temperature of the system. When two bodies of differing temperatures come into touch, heat is the energy exchanged between them.
The term "exothermic reaction" refers to a reaction that releases energy. An exothermic reaction, in other words, produces heat. The temperature of the reaction will rise unless it is cooled in some way. When you use an external heater to raise the temperature, it slows or reverses the reaction, reducing the number of products while increasing the amount of reactants.
Hence the correct answer is D.

What is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 j/(gk, is heated from -25°c to -15°c?
Answer:
[tex]Q=20.6\frac{J}{g}[/tex]
Explanation:
Hello there!
In this case, according to the equation for the calculation of the heat during a heating process:
[tex]Q=mC(T_f-T_i)[/tex]
It is possible to compute it per gram of ice by just removing m from the equation by dividing at both sides. Next we plug in the given specific heat and the final and initial temperatures to obtain:
[tex]Q=2.06\frac{J}{g\°C}[-15\°C-(-25\°C)] \\\\Q=20.6\frac{J}{g}[/tex]
