Answer:
glucose and oxygen
Explanation:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
What are new substances formed in a chemical reaction called?
Answer:
Products
Explanation:
Reactants → Products
Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.
Answer: They are the PRODUCTS of the reaction.
Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.
The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.
The products are the "meal," or what the reactants combined to create.
For example, when creating salt or NaCl, this is essentially the formula:
Na + Cl = NaClIn this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.

Which of the following shows correctly an ion pair and the correct formula for the ionic compound the two ions form?
A) Cu1+, O2–; CuO
B) Cr3+, I–; CrI
C) Sn4+, N3–; Sn4N3
D) Fe3+, O2–; Fe2O3
Answer:
D) Fe³⁺, O²⁻; Fe₂O₃
Explanation:
Option D shows correctly an ion pair and the correct formula for the ionic compound the two ions form.
Ion pairs of iron and oxygen react to form iron (III) oxide. The iron (III) oxide is one of the oxides of iron. The compound is usually attacked by acids and it is often called rust. It is used in the feedstock of the steel and iron industries. This means that the compound is used in the production of iron, steel, and many alloys.
Below are some equations:
4 Fe + 3 O₂→ 2 Fe₂O₃
Fe⁰ + 3O₂⁰ → Fe³⁺O₃²⁻

Example of market structures of monopoly
Answer: A monopoly is the absence of competition in the market.
Explanation:
In such circumstances, the market creates a monopoly of one producer who takes huge capital and dictates prices. An example of a monopoly on the market is the existence of only one company that makes up the entire economic branch. In such circumstances, the monopolist can increase the product's price without losing the entire sale, i.e., operating successfully. In that situation, the monopolist remains the only one on the market, and the competition has no access to the market.
Determine the molarity of a solution formed by dissolving 4.83 moles of NaCl (M=58.44 g/mol) in enough water to yield 2.16L of solution. round to three sig figs. do not include units.
The molarity of a solution : 2.24
Further explanationMolarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]
Where
M = Molarity
n = number of moles of solute
V = Volume of solution (L)
4.83 moles of NaCl in 2.16 L solution
n = 4.83
V = 2.16 L
Molarity :
[tex]\tt M=\dfrac{4.83}{2.16}=2.2361\rightarrow 3~sig~figs=2.24[/tex]
The air in a syringe has volume 25.0 mL
when the pressure is 4.38 atm. What will be
its volume when the pressure is 0.65 atm?
Answer:
168.46 mLExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question we have
[tex]V_2 = \frac{25 \times 4.38}{0.65} = \frac{109.5}{0.65} \\ = 168.46153...[/tex]
We have the final answer as
168.46 mLHope this helps you

A current of 5.29 A is passed through a Sn(NO3)2 solution for 1.30 h . How much tin is plated out of the solution?
Answer:
15.26 g of tin
Explanation:
Given that the equation of the process is;
Sn^2+(aq) + 2e ------> Sn(s)
Since 1e = 1F= 96500 C
but q =It
t is in hours so it must be converted to seconds, the SI unit of time
Hence;
119g of tin is deposited by 2 * 96500 C
xg of tin is deposited by 5.29 * 1.30 * 60 * 60
x = 119 * 5.29 * 1.30 * 60 * 60/ 2 * 96500
x = 2946106.8/193000
x= 15.26 g of tin
A current of 5.29 A is passed through a Sn(NO₃)₂ solution for 1.30 hour, the amount of tin plated is 15.26 grams.
How do we calculate mass?Mass of any deposited susbatnce that is obtained by the passing of current will be calculated by using the Faraday's Law as:
W = ECT/F, where
W = required mass of deposited tin
C = current = 5.29 A
T = time period = 1.30hr = 4,680sec
F = faradays constant = 96500C
E = equivalent mass
Equivalent mass will be calculated as:
E = molar mass/charge on atom = 119/2 = 59.5 g/equ
On putting all these values in the above equation, we get
W = (59.5)(5.29)(4680) / 96500
W = 15.26 g
Hence mass of tin is 15.26 g.

You have 3.00 L of a 3.12 M solution of NaCl(aq) called solution A. You also have 2.00 L of a 2.00 M solution of AgNO3(aq) called solution B. You mix these solutions together, making solution C.
Calculate the concentration (in M) of Ag+ ions in solution C.
Answer:
[tex]M=0.8M[/tex]
Explanation:
Hello!
In this case, since the presence of silver ions is in AgNO3 only, we can compute their moles by using the volume and concentration of the corresponding salt:
[tex]n_{Ag^+}=2.00L*2.00\frac{mol}{L}=4molAg^+[/tex]
Next, since the total volume of solution C is 5.00 L, the required concentration of silver ions turn out:
[tex]M=\frac{4.00mol}{5L} =0.8M[/tex]

Which products of photosynthesis does your body break down to be used for cellular respiration?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
hope this helps!

You have 3.00 L of a 3.74 M solution of NaCl(aq) called solution A. You also have 2.00 L of a 2.00 M solution of AgNO3(aq) called solution B. You mix these solutions together to make solution C. Calculate the concentration (in M) of Cl ions in solution C.
Answer:
[tex]M=2.24M[/tex]
Explanation:
Hello!
In this case, since the molarity and volume of the solutions are given, we are able to compute the moles of chloride ions as they are present in NaCl only:
[tex]n_{Cl^-}=3.00L*3.74\frac{molNaCl}{L}*\frac{1molCl^-}{1molNaCl} =11.22molCl^-[/tex]
Next, since the mixing of solution A and B lead to a volume of 5.00 L, the concentration of chloride ions turns out:
[tex]M=\frac{11.22mol}{5.00L}=2.24M[/tex]
