1.09 moles of tin (Sn)
Explanation:
We have the following chemical reaction where tin chloride (SnCl₂) reacts with sodium (Na) to produce tin (Sn) and sodium chloride (NaCl):
SnCl₄ + 4 Na → Sn + 4 NaCl
Taking in account the chemical reaction, we devise the following reasoning:
if 1 mole of SnCl₂ will react with 4 moles of Na
then 2.34 moles of SnCl₂ will react with X moles of Na
X = (2.34 × 4) / 1 = 9.36 moles of Na
So, 2.34 moles of SnCl₂ will react with 9.36 moles of Na but we only have 4.36 moles of Na available. The limiting reactant will be Na. Knowing this we devise the following reasoning:
if 4 moles of Na produces 1 mole of Sn
then 4.36 moles of Na produces Y moles of Sn
Y = (4.36 × 1) / 4 = 1.09 moles of Sn

Answer:
O B. Convert the 10 g of NaCl to moles of NaCl.
Explanation:
The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.
(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl
58.44 is the molar mass of NaCl
m=0.1711 mol NaCl/2 kg H2O
m=0.085557837
Answer:
When water freezes and turns into ice, it releases latent heat. Then, the ice that builds up on the plant will insulate it from the colder surrounding air temperatures. Because of this, some growers choose to spray their crop with water before the freeze occurs.

Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
