Answer:
55.0 g
Explanation:
Step 1: Write the balanced equation for the production of oxygen
2 CO₂(g)⇒ 2 CO(g) + O₂(g)
Step 2: Calculate the mass of oxygen produced over a 2 hour period
The MOXIE produces 10.0 g of oxygen per hour.
2 h × 10.0 g/1 h = 20.0 g
Step 3: Calculate the moles corresponding to 20.0 g of O₂
The molar mass of O₂ is 32.00 g/mol.
20.0 g × 1 mol/32.00 g = 0.625 mol
Step 4: Calculate the number of moles of CO₂ needed to produce 0.625 moles of O₂
The molar ratio of CO₂ to O₂ is 2:1. The moles of CO₂ needed are 2/1 × 0.625 mol = 1.25 mol
Step 5: Calculate the mass corresponding to 1.25 moles of CO₂
The molar mass of CO₂ is 44.01 g/mol.
1.25 mol × 44.01 g/mol = 55.0 g

Answer:
(1) Z = 82, M = 208; (2) Z = 82, M = 208
Step-by-step explanation:
(1) Decay of Th-232
The unbalanced nuclear equation is
The main point to remember in balancing nuclear equations is that the <em>sums of the superscripts and the subscripts must be the same on each side</em> of the equation.
Then
90 = x + 6×2 + 4(-1), so x = 90 – 12 + 4 = 82
232 = y + 6×4 + 4×0, so y = 232 – 24 = 208
Z = 82, M = 208
(2) Decay of U-238
The unbalanced nuclear equation is
Then
92 = x + 6×2 + 2(-1), so x = 92 – 12 + 2 = 82
238 = y + 6×4 +4×0, so y = 238 – 24 = 214
Z = 82, M = 214
