Hey there!:
H is always +1 so the H's have a +3 charge.
O is always -2 so the O's have a -8 charge .
Now, suppose oxidation state for P = X , then :
+3 + X + (-8) = 0 (because of neutral molecule)
x = 8 - 3
x = + 5
So, X = +5 oxidation state.
Answer C
Hope that helps!

A) the independent variable is the variable that doesn’t rely on another variable. For this question the independent would be the days.
b) the dependent variable is the number of bacteria
c) ‘Number of bacteria across a number of days’
pH. 10 because it is strong base
<span>Kinetic energy is the energy at move or at motion. The kinetic energy of objects depend on its mass (m) and its </span>velocity (v)<span>. The mass of an object can be measured in kilograms while its mass can be measured in meters per second. The objects' energy at motion is very dependent to its mass and velocity therefore, the formula in finding the kinetic energy of an object is </span>
K = 1/2 x mass (m) x velocity (m/s)2
<span>On the other hand, the kinetic energy of atoms and molecules are measured differently. It is measured through temperature.<span>
