7 grams of Oxygen. The Law of conservation of mass says that mass can be neither created nor destroyed, so the total mass of the products (in this case the oxygen plus the mercury) must equal the total mass of the reactants (in this case, the mercuric oxide).
Beacause they all belong to a partcular kingdom which operates protons
Answer: THE ANSWER IS D
Explanation:
an alcohol is a hydrocarbon chain with an hydroxyl group (OH)
A, B, AND C ARE ALL ALCOHOLS, SO THE ANSWER IS D
1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.
the algal population will decrease.
