Answer:
<em><u>constant</u></em>
Explanation:
In consideration of the conservation principle of linear momentum
Answer:
6.2 moles of K2CO3 can be converted to 856.8741 grams.
2.4 x 10²² atoms
<h3>Further explanation</h3>
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
So the atomic mass obtained is the mass of the atom relative to the 12th carbon atom
mass single Uranium atom=4.7 x 10⁻²² g
then for 111 mg=0.111 g

answer is A
The kinetic theory is used to explain the behaviour of gases.
One of the assumptions states that "a gas is composed of a large number of identical molecules moving at different speeds".
Between atoms (one metall and one non metall) form an ionic bond(NaCl)
