Answer:
0.019 moles of M2CO3
Explanation:
M2CO3(aq) + BaCl2 (aq) --> 2MCl (aq) + BaCO3(s)
From the equation above;
1 mol of M2CO3 reacts to produce 1 mol of BaCO3
Mass of BaCO3 formed = 3.7g
Molar mass of BaCO3 = 197.34g/mol
Number of moles = Mass / Molar mass = 3.7 / 197.34 = 0.0187 ≈ 0.019mol
Since 1 mol of M2CO3 reacts with 1 mol of BaCO3,
1 = 1
x = 0.019
x = 0.019 moles of M2CO3
Answer:
This would affect the communities that use solar energy greatly, in a negative way.
Explanation:
If the moon were twice its size, and cast a larger shadow on Earth, the shadow would black out the earth to an almost night time, during the day. We would have a 24+ hour night, and communities relying on nothing but solar energy would be out of power until the sun was out again.
