Answer:
70 180 000 kg
Explanation:
We can solve this problem by multiplying the amount of garbage each Canadian throws out each day (2.2 kg) by the number of Canadians:
- 2.2 kg/person * 31 900 000 persons = 70 180 000
Thus according to this problem, all Canadians throw out 70 180 000 kg of garbage each day.

Penta - five
Second element ends with -ide
Answer:
B. Reduction occurs at the cathode.
Step-by-step explanation:
That's the <em>definition</em>: The cathode is the electrode at which reduction occurs.
A is <em>wrong</em>. The cathode gains electrons through the external circuit.
C is <em>wrong</em>. The cathode has the electrons, so cations move toward it.
D is <em>wrong</em>. Reduction occurs at the cathode, so the oxidation number decreases.

Mass of Li₂O= 719.809 g
<h3>Further explanation</h3>
Given
1,060 g of CO₂
Required
Mass of Li₂O
Solution
Reaction
<em>Possible compound : Li₂O </em>
Li₂O(aq) + CO₂(g) → Li₂CO₃(aq)
mol CO₂(MW=44 g/mol) :
= 1,060 g : 44 g/mol
= 24.09
From the equation, mol ratio of LiO : CO₂ = 1 : 1, so mol Li₂O : 24.09
Mass Of Li₂O(MW=29.88 g/mol) :
= mol x MW
= 24.09 x 29.88
= 719.809 g
