xA balloon is filled to a volume of 1.50 L with 3.00 moles of gas at 25.0 °C. With pressure and temperature held constant, what will be the volume (in L) of the balloon if 0.90 moles of gas are added?

for points guys

it would be a gas formation

the answer is barium and copper bromide

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
