Answer:
There are 2 moles of oxygen molecules; there are 4 moles of oxygen atoms.
Explanation:
A solution with a higher concentration of hydroxide ions than hydrogen ions is basic solution.
This solution formed by Base dissolved in water and release hydroxide ions.
The PH of the solution is greater than 7
Its a formula relating to specific heat capacity
Δθ refers to the change in temperature
Q refers to the energy neededto raise the temperature of an object by the change in temperature
m stands for the mass of tje object
c is the specific heat capacity which is the amount of energy needed to heat up an object per unit mass
Probably true because chemicals do control weed and it hurts the environment.
