The answer is the third one .
Answer:
c or d I think but I'm not completely shure
Answer:
Balanced equation is: 2Na (s) + Cl₂(g) → 2NaCl (s)
Number of moles of needed Cl₂ → 0.217 moles
Mass of needed Cl₂ → 15.4 g
Explanation:
We determine the reaction
2Na (s) + Cl₂(g) → 2NaCl (s)
We convert the mass of solid Na to moles
10 g. 1 mol/23 g = 0.435 moles
Ratio is 2:1. 2 moles of Na react with 1 mol of chlorine
Then, 0.435 moles of Na may react with (0.435 . 1)/2 = 0.217 moles of Cl₂
Number of moles of needed Cl₂ → 0.217 moles
We convert the moles to mass → 0.217 mol . 70.9 g/1mol = 15.4 g
Answer:
0.5968 g/mL
Explanation:
To calculate density:
density
Therefore,12.52g divide by 20.98mL is 0.5968g/mL
Answer:
The more water vapor in the air parcel, the more condensation can occur, and therefore, more rain. ... The air parcel then loses more energy, causing more rainfall. Wind pushes air parcels even higher in the troposphere, where it is colder. The air parcels will then lose more energy and more rain can happen.
I think is FALSE, is that right?
