Answer:
Explanation:
This experiment demonstrate that a plant don't need only water to grow and increase its mass.
A plant will also need nutrients located in the soil that will help it grow and increase its mass.
Answer:
$1,194.59 - Checking
$2,381.47 - Savings
Explanation:
$478.61 + $715.98 = $1,194.59
$3,097.45 - $715.98 = $2,381.47
The chemical reaction involving Mg(OH)2 and HCl is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we see that for every 2 moles of HCl, 1 mole of Mg is
reacted.
Calculating for moles HCl:
moles HCl = 0.300 M * 0.215 L
moles HCl = 0.0645 mol
The moles Mg then is:
moles Mg = 0.0645 mol * (1 / 2)
<span>moles Mg = 0.03225 mol</span>
the answer is d
i know thiis because i used google hehe
<u>Answer:</u> The molality of 
solution is 4.013 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg.
The formula used to calculate molarity:
.....(1)
Given values:
Given mass of = 20.0 g
Molar mass of = 62.3 g/mol
Mass of solvent = 80.0 g
Putting values in equation 1, we get:
Hence, the molality of solution is 4.013 m
