PH is the amount of hydrogen ion concentration in a sample. Basic because a ph of 0-7 is acidic and 7-14 is basic
The answer is C lol i just guessed on USA test prep and I was right
The answer is the third one .
Answer:
Explanation:
Hello,
In this case, the undergoing reaction is:
Thus, since the Kp is given, it equals the partial pressure of carbon dioxide since the equilibrium expression only consider the gaseous species, hence:
Therefore, by considering the given pressure and temperature, one computes the moles of carbon dioxide:
In such a way, carbon dioxide and calcium oxide have a 1-to-1 molar relationship, thereby, the mass of calcium oxide turns out:
Best regards.
Answer:
2
Explanation:
The coefficient for O is 2 and this is an example of a combustion reaction. With the help of the coefficient 2 infront of oxygen, this equation now demonstrates law of conservation of mass.
