Answer:What is the actual Molar mass of M?
Explanation:
The mass of the M is measured before, and after heating. Therefore, its easy to calculate the oxygen required to heat the M. Applying that to the reaction M+O₂⇒MO, will get you all the information about the Oxygen, and therefore you can calculate the Molar mass of M.
Chemical reactions convert reactants to products, whose properties differ
from those of the reactants. Chemical equations are a compact and
convenient way to represent chemical reactions. They have the general form
Reactant(s) → Product(s)
The arrow in the equation means "changes to" or
"forms." The reaction of gaseous nitrogen with hydrogen to
produce ammonia, NH

, is represented by the chemical equation
Although there are thousands of chemical reactions, a significant number
of them, especially those that are not organic reactions, can be
classified according to four general patterns: combination, decomposition,
displacement, and exchange.

Answer:
B. Lower
Explanation:
Remember that the pH is calculated as
-log (H30 +)
That is, at a higher concentration of H30 +, with the -log, the pH value decreases and vice versa.
With a concentration 1e-5, it yields a pH of 5.00 and with 1e-2 a value of 2.00
The most common pairing would be sodium forming an ion after transfering an electron to chlorine
