Answer:
They fall slower.
Explanation:
moon's gravitation force is effected by the mass of the moon
but because the moon has less mass,
objects fall slower because it has less gravitation force

Answer:
A)21
Explanation:
To know the difference between the number of electrons in the two atoms, we must first know the number of electrons in the atoms.
For Selenium, Se, we have 34 electrons. The element is in group 6 on the periodic table.
Aluminum on the other hand is in the Boron family with a total of 13 electrons.
The difference,( 34-13) electrons gives a total of 21 electrons
There had been new discoveries of chemicals that have been added to the periodic table in recent years
Answer:
A(g) + B(g) → 3C(g).
Explanation:
As the no. of gaseous molecules increases in the product side than the reactants, disordering occurs and ΔSrxn be more positive.
as in: A(g) + B(g) → 3C(g).
the no. of gaseous molecules in the reactants side (2) and be (3) in the products side, disorder increases.
While, as the no. of gaseous molecules decreases in the product side than the reactants, ordering occurs and ΔSrxn be more negative.
as in:
2A(g) + B(g) → C(g)
,
the no. of gaseous molecules in the reactants side (3) and be (1) in the products side, ordering increases.
2A(g) + 3B(g) → 4C(g)
,
the no. of gaseous molecules in the reactants side (5) and be (4) in the products side, ordering increases.
2A(g) + B(s) → 3C(g).
the no. of gaseous molecules in the reactants side (3) and be (3) in the products side, ordering is the same.
