Answer:
429 calories
Explanation:
Using the specific heat equation, Q=mcΔt and solving for Q will give the number of calories.
Q=(250 g)(0.033 cal/g*C)(52C)= 429 cal
Answer:
D. Q does not depend on the concentration or partial pressures of reaction components
The balanced reaction would be as follows:
<span>3NaOH + H3PO4 --> Na3PO4 + 3H20
We are given the concentration and the amount of the reactants to be used. We use these values for the calculations as follows:
</span><span>How many mL of .225 M NaOH will react with 4.568g H3PO4?
4.568 g (1 mol / 98 g) ( 3 mol NaOH / 1 mol H3PO4 ) ( 1 L / .225 mol NaOH ) = 0.621 L or 621 mL of .225 NaOH</span>
find mass of oxygen by subtracting mass of phosphorus from the total mass
divide the masses by the molar mass to get moles
divide moles by the smallest amount of moles
multiply by 2 to get a nice number
P4O5
