Select the correct answer. A sealed, flexible container held 250 mL of a substance. The volume of the container was then decreased to 100 mL without any matter
escaping. What must be true about the matter in the container before the container's volume was changed?
OA .
It would have kept its shape if transferred to another container.
OB.
Its particles were held together tightly in a rigid structure.
OC. Its particles were in constant, rapid motion.
OD
It was all located at the bottom of the container.

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

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.
