Answer:
71g (assuming experimental data)
Explanation:
The balanced equation for this reaction:
+
→
+ 
Molar mass of H2SO4 = 98.1 g/mol
molar mass of NaOH = 40g/mol
Molar mass of Na2SO4 = 142.04g/mol
⇒ 1 mole or 98.1g of H2SO4 will yield 1 ole of NaSO4; alternately, 2 moles or 49 ×2 = 80g of NaOH produces 1 mole of NaSO4.
<em>Therefore, limiting reactant is NaOH.</em>
Assuming actual experiment is 20g of NaOH,
1 mole - 40g
x moles - 20g =
= 0.5 moles
⇒1 mole of Na2SO4 - 142.04g
∴ 0.5 moles = 142.04 × 0.5
<u>= 71.02g</u>
Hmm. This is very unspecific but it could either be indicating the pH of the solution or just saying it is an aqeous solution.
Answer:
chlorine atom
A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.
Explanation:
To avoid drought symptoms. If sprinklers are being used it takes water from the reservoirs and there is no recycling of the water occurring
Runoff from snowmelt is a major component of the global movement of water, possibly even if you live where it never snows.
