Length of wood = 1.2 m
Carlos wants to cut it into 3 equal parts.
So, length of each part = (1.2/3) m = 0.4 m = (0.4×1000) mm = 400 mm
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
Yes because the cold water has slower moving molecules.
When the element is reduced it gains electrons, maybe it's charge becomes more negative.
