Answer: 1.314 ppm
explain: thats what someone said
An electric motor produces heat while running. The amount of heat is roughly equivalent to the amount of power delivered to the motor.
Answer:
a) Mass of solid W crystallized out 0°C is 141.564 g
b) 91.92% is the percent recovery.
Explanation:
The solubility of solid W in water at 100°C = 21.3 g/100 mL
Volume of water at 100C required to dissolve 154.0 g of W: x
723.0 mL of water will dissolve 154.0 grams of solid W.
The solubility of solid W in water at 0°C = 1.72 g/100 mL
Mass of W soluble in 723.00 mL of water at 0°C = m
a) Mass of solid W crystallized out 0°C : 154.0 g- 12.436 g=141.564 g
b) Percent recovery of solid at 0°C:
91.92% is the percent recovery.

Answer:
D: Decomposition Reaction
Explanation:
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
The general form of a decomposition reaction is: AB -> A+B.
You just split the nonmetals into a molecule depending on the element.
But they are rules though when doing this reaction. If a element is a diatomic molecule, then you would write a 2 in the subscript.
Diatomic molecules contain two atoms that are chemically bonded
<h3>The 7 diatomic elements are: </h3><h3>H: Hydrogen H2</h3><h3>N: Nitrogen N2</h3><h3>F: Fluorine F2</h3><h3>O: Oxygen O2</h3><h3>I: Iodine I2</h3><h3>C: Carbon C2</h3><h3>B: Bromine B2</h3>
Now let us go back to this problem: 2H2O -> 2H2 + O2
So water or 2H2O split into 2H2 and O2 because hydrogen and oxygen are diatomic elements.
That is how you write the product of a decomposition reaction.
Hope it helped!
