Ill say <span>calcium hydroxide but hope this helps :)</span>
Answer: sorry hun can’t help with this I was asked different questions when I learned this :,)
Explanation: have a nice day
We are given the following equation:
y = y0 e^-0.0001216 t
where y = 1/5 y0, y0 is the original amount
So solving for time t:
1/5 y0= y0 e^-0.0001216 t
t = 13,235.51 years
So the human died about 13235.5 years ago
increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.
Explanation:
The concentration of NO at equilibrium will increase when the reaction takes place at a higher temperature because increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.
The reaction is an endothermic reaction.
N₂ + O₂ + heat ⇄ 2NO
According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed the system will adjust itself in order to annul the effect of the change".
- In an endothermic reaction, heat is usually absorbed.
- We see that in the backward reaction, heat is absorbed.
- If the temperature of this reaction is increased, the backward reaction is favored more.
- Since the reactants are combining better, more products NO results.
