A little boy is playing with a plastic water bottle. He blows air into the bottle to make a whistling sound. Then, he wedges a p
lastic ball into the bottle to make a rattle. But the ball is too big—it gets stuck in the mouth of the bottle! The little boy panics and runs to his big brother for help. Luckily, his older brother just studied the principle of Boyle's law. Based on what he learned, how will he get the ball out of the bottle? by pushing down on the bottle to increase the air pressure inside the bottle , by pushing down on the bottle to increase the air pressure inside the bottle by placing the bottle in the freezer to increase the air pressure inside the bottle , by placing the bottle in the freezer to increase the air pressure inside the bottle by pushing down on the bottle to decrease the temperature of the air in the bottle , by pushing down on the bottle to decrease the temperature of the air in the bottle by placing the bottle in the freezer to decrease the mass of the air inside the bottle
Predator and prey because herbivores are animals that only eat plants implying they wouldnt eat the carnivore as the carnivore would eat them because carnivores only eat animals such as the herbivore
According to the equation, the ratio of the reactant Cu and product CuO is 2:2, thus 1:1. Therefore to produce 2.44 mol CuO, 2.44 mol Cu is required. The molecular weight of Cu is 64. So the mass of Cu that is required to produce 2.44mol CuO is 2.44mol * 64 g/mol = 156.16 g.
