Answer:
+3
Explanation:
The oxidation number of a specie is the charge that it appears to have as determined by some arbitrary rules.
If we look at the reaction, we will notice that arsenic is more electro positive than chlorine so it is likely to function as the reducing agent in the reaction, loosing three electrons to have an oxidation number of +3 in the product.
Answer:
What is energy transformation? One type of energy can change into another type of energy. Energy transformation means the changing of energy from one type to another, e.g. from kinetic energy to electrical energy, or from potential energy to kinetic energy.

To calculate the amount of heat entering or leaving a system, the equation <span>Q=mcΔT</span> is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.
<span>25°C−0°C=25°C</span>
<span>Q=mcΔT</span>
<span>Q=25grams⋅4.19<span>J<span>g°C</span></span>⋅25°C</span>
<span>Q=2618.75J</span>
Take into account significant figures and the answer should be
<span>2.6⋅<span>103</span><span>J</span></span>
