Answer: it would stop producers from producing food.
Explanation: why? Without the action of the producers to turn sunlight into food, the producers would die, and consumers that rely on them would lose their food source and die too.
Answer:
It would stop producers from producing food
Explanation:
Producers would die, and if producers died, consumers would die too.

48 g of Aluminum will produce how much heat (in kJ) for this reaction?
Use the following reaction:
2 Al + 3 CuSO4 → 3 Cu + Al2(SO4)3 ∆H = -680 kJ
Round your answer to a positive whole number and do not write the unit.
The heat produced from 48 g Aluminium = -578
Further explanationGiven
Reaction
2 Al + 3 CuSO4 → 3 Cu + Al2(SO4)3 ∆H = -680 kJ
48 g of Aluminum
Required
Heat released
Solution
mol of Aluminium = mass : Ar Al
mol = 48 g : 27 g/mol
mol = 1.78
From the reaction, heat released for 2 moles Al, so for 1.78 Al, the heat released :
[tex]\tt \dfrac{1.7}{2}\times -680~kJ=-578~kJ[/tex]

Which has a bigger surface area, powder or marble chips
Answer:
powder
Explanation:
Between the powder and marble chips, the powder will have a larger surface area.
For the same masses of a solid substance in different forms such as lump, granules or powder, the smaller particle size of each form the larger the surface area.
Surface area increases from lumps to granules and them powder
A powder has the largest surface area and hence undergoes a more faster chemical reaction.What is the name of the compound whose formula is Re2O

What ara the differences between the homolytic and heterolytic bond dissociation ? And why homolytic dissociation energy of H-H (104 KJ/mol) is lower than its heterolytic bond dissociation energy (401 KJ/mol)?
Answer:
Following are the difference in homolytic and hetrolytic bond dissociation.
Homolytic dissociation is referred as the amount of energy released during homolytic fission. Homolytic fission is known as the dissociation of chemical bond in two equal fragmentswhereas, Hetrolytic dissociation is referred as the amount of energy released during Hetrolytic fission. Hetrolytic fission is known as the dissociation of chemical bond in two unequal fragments.Homolytic fission gives one electron each to its fragments whereas Hetrolytic fissiongives two electron to one fragment and zero electron to other fragment.Energy released during Homolytic fission is lower than the Hetrolytic fission as the electron distribution to its fragments is uniform in homolytic whereas electron distribution to its fragments is uniform in hetrolytic fission.
Thus bonds form in hetrolytic fission is more stronger than the the bonds formed in homolytic fission.
Hence, more energy is required to break the bonds of hetrolytic fission as compared to homolytic fission
Thus, homolytic dissociation energy of H-H (104 KJ/mol) is lower than its heterolytic bond dissociation energy (401 KJ/mol)

What happens at the anode in an electrolytic cell?
A. Turning an ion into an uncharged atom
B. Melting
C. Reduction
D. Oxidation
Answer:
D. Oxidation
Explanation:
In an electrolytic cell, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.
A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).
What makes this inauguration different from the past?
Answer:
there's just a lot of drama around grumpy trumpy's StOlEN eLecTiOn which are all just fake claims. all his hardcore followers are brainwashed into believing anything he says, so people (especially people who are inside the capitol) fear that trump's followers might incite violence AGAIN even after they broke into the Capitol on the 6th.
That's why they have the National Guard and thousands of people to keep the building secure during Biden's Inauguration.

Suppose that you take a sample of 500 g of ocean water and let the water evaporate. The mass of the remaining salts is 17 g. What was the salinity of the ocean water
Answer: The salinity of ocean water is 34 ppt.
Explanation:
Salinity is defined as the number of grams of salts present per kilogram of seawater. It is expressed in parts per thousand.
The formula used to calculate the salinity of ocean water or sea water is:
[tex]\text{ Parts per thousand}=\frac{\text{Mass of salts}}{\text{Mass of sea water}}\times 1000[/tex]
We are given:
Mass of salts = 17 g
Mass of sea water = 500 g
Putting values in above equation, we get:
[tex]\text{ Parts per thousand}=\frac{17g}{500g}\times 1000\\\\\text{ Parts per thousand}=34[/tex]
Hence, the salinity of ocean water is 34 ppt.

Two inductors are connected in series to a 120 volt, 60 Hz line. The values are .75 H and 1.47 H. The total inductive reactance is
Answer:
837.02 ohms
Explanation:
Step one:
Given data
Frequency= 60Hz
L1= 0.75H
L2= 1.47H
When inductors are connected in series, the total inductance is the sum of the individual inductance
Step two:
Inductor 1
[tex]Xl1= 2\pi fL\\\\Xl1= 2*3.142*60*0.75\\\\Xl1= 282.78 ohms[/tex]
Inductor 2
[tex]Xl2= 2\pi fL\\\\Xl2= 2*3.142*60*1.47\\\\Xl2= 554.24 ohms[/tex]
The total inductance is
=282.78+554.24
=837.02 ohms

How does energy from Earth’s interior affect surface changes?
Answer:
Energy produced deep inside Earth heats rock in the mantle. ... As it becomes less dense, the heated rock rises toward Earth's surface. The cooler, denser rock surrounding the heated rock sinks, as Figure 5 shows. In this way, heat inside Earth moves toward the cooler crust.
Explanation:
do you like my og name
Energy from Earth’s interior affect surface changes due to:
Earth heat transport occurs by conduction, mantle convection, hydrothermal convection, and volcanic advection. Thus, about 99% of Earth's internal heat loss at the surface is by conduction through the crust, and mantle convection is the dominant control on heat transport from deep within the Earth.Tectonic processes and flow in Earth's interior drive deformation of Earth's surface that can lead to destructive earthquakes, tsunamis, and volcanic eruptions.Learn more:

(4) NH3+02- NO+H2O
balance the equation
Answer:
4NH₃ + 5O₂ —> 4NO + 6H₂O
Explanation:
NH₃ + O₂ —> NO + H₂O
The above equation can be balance as follow:
NH₃ + O₂ —> NO + H₂O
There 3 atoms of H on the left side and 2 atoms on the right side. It can be balance by 4 in front of NH₃ and 6 in front of H₂O as shown below:
4NH₃ + O₂ —> NO + 6H₂O
There are 4 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 4 in front of NO as shown below:
4NH₃ + O₂ —> 4NO + 6H₂O
There are 2 atoms of O on the left side and a total of 10 atoms on the right side. It can be balance by putting 5 in front of O₂ as shown below:
4NH₃ + 5O₂ —> 4NO + 6H₂O
Thus, the equation is balanced.

A certain ore is 37.3 % nickel by mass. How many kilograms of this ore would you need to dig up to have 65.0 g of nickel
Answer:
0.174kg of Ore are required
Explanation:
The ore of 37.3% in nickel by mass means that in 100g of ore there are 37.3g of nickel. As we need to obtain 65g of nickel we can convert this mass to mass of ore using the conversion factor (100g Ore / 37.3g Nickel) as follows:
65g of nickel * (100g Ore / 37.3g Nickel) = 174g of Ore are needed to have 65.0g of nickel. In kilograms:
174g Ore * (1kg / 1000g) =
