Answer:
The atom becomes positively charged.
Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
The mass of Fe(NO3)2 you have is 245 g * 0.805 = 197.23 g
<span>The molar mass of Fe(NO3)2 is 179.85 g/mole so you have 1.0966 moles </span>
<span>From the balanced equation, that is the number of moles of Fe you make since both Fe(NO3)2 and Fe have a 3 in front of them. </span>
<span>The mass of Fe is 1.0966 moles * 55.85 g/mole (atomic mass of iron) = 61.246 g. From the information you are given, your answer should be in 3 sig figs so 61.2 g </span>
<span>Moles of HCl = 8.2 L * 3.5 mole/L = 28.7 moles </span>
<span>From the balanced equation, you need 1/2 the moles of zinc as you have of HCl so you need 14.35 moles. </span>
<span>To get the mass of zinc, multiply moles of zinc by its atomic mass = 938.2 g. From the information given, your answer should be in 2 sig figs so I would report it as 9.4 * 10^2 g, that clearly shows 2 sig figs.</span>
