Last ones!!! 1. One molecule of Iodine (I2) and two molecules of potassium (NaCl) combine in a reaction. How many atoms are in the products?

a. 6
b. 4
c. 3
d. 2

2. Which statement comparing ionic and covalent bonds is correct?

a. Elements in Group 1A are more likely to form covalent bonds than ionic bonds with other atoms.
b. Covalent bonds tend to be less polar than ionic bonds.
c. More electrons are transferred from covalent bonds than ionic bonds.
d. The difference between electronegativities is greater in covalent bonds than for atoms in ionic bonds.

3. Which statement correctly compares synthesis and decomposition reactions?

a. Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form AB β†’ A + B, while decomposition reactions are in the form A + B β†’ AB.
b. Synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form A + B β†’ AB, while decomposition reactions are in the form AB β†’ A + B.
c. Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form AB β†’ A + B, while decomposition reactions are in the form A + B β†’ AB.
d. Synthesis and decomposition reactions are both neutralization reactions. Synthesis reactions are in the form A + B β†’ AB, while decomposition reactions are in the form AB β†’ A + B.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
