1. Explain why using renewable resources might be a good choice? Why do you think that?

1 answer:

7 0

Hi there. I suggest doing this yourself but here are my answers in my own words

1) Using renewable resources might be an amazing choice due to the fact that there will be less pollution. If humans continue using non-renewable resources, humans will make the oxygen contaminated. Also, renewable resources will never run out so there isn't any harm getting them

2) The environmental impact of using non-renewable resources is that more carbon dioxide will be released which causes pollution which is harmful to the human body. Renewable resources are unlimited and don't cause any pollution

Nitrogen and oxygen react at high temperatures. N2(g) + O2(g) equilibrium reaction arrow 2 NO(g) ΔH = 182.6 kJ (a) What will hap

FromTheMoon [43]

<u>Answer:</u> This will result in the increase of concentration of NO and decrease in the concentrations of nitrogen gas and oxygen gas.

<u>Explanation:</u>

The given chemical equation follows:

$N_2(g)+O_2(g)\rightleftharpoons 2NO(g);\Delta H=182.6kJ$

As, enthalpy of the reaction is positive. So, it is an endothermic reaction.

For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.

$A+\text{heat}\rightleftharpoons B$

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

If the concentration of oxygen gas is increased, the equilibrium will shift in the direction where the concentration of oxygen gas will be decreased. Thus, the reaction will shift in the right direction or forward direction.

Hence, this will result in the increase of concentration of NO and decrease in the concentrations of nitrogen gas and oxygen gas.

What is the volume in liters of 3.46kg of ethylene glycol?

iogann1982 [59]

Answer:

The answer to your question is:

Explanation:

Data

V = ?

mass = 3.46 kg

Density = 1116 kg/m³

Formula

density = mass / volume

volume = mass / density

Substitution

volume = 3.46 kg / 1116 kg/m³

volume = 0.0031 m³ = 3.1 liters

Explain the reaction that would occur in a galvanic cell between solutions of Al 3+and Pb 2+ . Identify the oxidation and reduct

borishaifa [10]

Answer:

Al ==> Al^3+ + 3e

Pb^2+ + 2e ==> Pb

Oxidation is the loss of electrons. Reduction is the gain of electrons. Which half rxn above lost and which gained?

For the potential of the cell, look up the reductions potentials, change the sign of the Al half cell, add in the potential for the Pb and add them.
