The scientist will repeat the experiment to make sure that
his results are reliable.
I believe this would be an exothermic reaction, As time increases, the temperature goes up meaning the heat from the system is going into the surroundings. Which indicates an exothermic reaction.
Answer:
958 g is the mass of LiOH that can react with all the CO₂
Explanation:
CO₂(g) + 2 LiOH(s) → Li₂CO₃(aq) + H₂O
We think in the reaction:
1 mol of carbon dioxide can react with 2 moles of lithium hydroxide.
First of all, we convert the mass of our reactant to mol:
880 g . 1mol /44g = 20 moles
As ratio is 1:2, 20 moles of CO₂ will react with 40 moles of LiOH.
Let's determine the mass:
40 mol . 23.95 g /1mol = 958 g
Answer:
64 moles
Explanation:
Let us begin by writing a balanced equation for the reaction. This is illustrated below:
2Na + Cl2 —> 2NaCl
From the equation above,
1 mole of Cl produced 2 moles of NaCl.
Therefore, 32 moles of Cl will produce = 32 x 2 = 64 moles of NaCl.
Therefore, 64 moles of NaCl are produced
