Answer:
See below
Explanation:
<u>Specific Heat of water</u> = 4.186 J/(g-C)
J/(g-C) multiplied by g and C results in J
4.186 * 540 * (95-32) = <u>142 407 .72 J</u>
We can solve the equation and show the solution below:
Oxygen atomic number is 16.
Phosphorus atomic number is 32.
We have the molecular weight:
Molecular weight = (31*4) + (16*10)
Molecular weight = 284 grams/mol
Solving for the grams:
0.4 mole (for P4) * (1 mol P4O10/1 mol P4) * (284 grams P4O10/1 mole P4O10)
Total grams = 113.6
The answer is 113.6 grams.
Answer:
what kind of home work u dogeing
Explanation:
<h3>
Answer:</h3>
7.502 kilo calories
<h3>
Explanation:</h3>
<u>We are given;</u>
- Quantity of heat, Q as 31.39 kJ
We are required to convert it to kilo calories
First, we convert it to Joules
1 kJ = 1000 J
Therefore;
31.39 kJ will be equivalent to 31390 Joules
Second we convert Joules to calories using a suitable conversion factor
The suitable conversion factor is 4.184 J/Cal
Thus;
31390 Joules will be equivalent to;
= 31390 J ÷ 4.184 J/Cal
= 7502.39 Cal
Third, we convert calories to kilo calories
1 kCal = 1000 cal
Therefore;
7502. 39 Cal will be equivalent to;
= 7502.39 ÷ 1000
= 7.50239
=7.502 kilo calories
Hence, 31.39 kJ will correspond to 7.502 kilo calories
