Chemistry
1 answer:

Answer:

C, physical change

Explanation:

take a look at the equation. Next to each form of water do you see the little (g) and (l)? These represent the state of matter the water is in. So, the water is going from a gas to a liquid. The chemical compound is the same so its a physical change, not chemical, and it is reversible. You could change the liquid water back to the gas through evaporation. Endothermic has literally nothing to do with this equation so you can easily eliminate that answer choice.

A mouse runs across a 4.56 m kitchen floor in 3.42 seconds . What is the velocity of the mouse
Lerok [7]
Velocity is the change in position divided by the time . In your problem, it should be expressed in meters per second. To solve, you must divide the distance, 4.56 meters, by the time it takes to travel that distance, which is 3.42 seconds ----->   4.56/3.42 = 1.333 meters per second is the velocity of the mouse

A 3.689 g object is added to 7.29 mL of water causing The water level to rise to 8.54 ML. What is the density of the object? Rou
Marina CMI [18]

Answer:

2.95 g / mL

Explanation:

For this problem, we will simply use the equation that density is equivalent to mass over volume.  We are given the mass of the object and the initial and final volumes of water in the cylinder.  Thus we can find the density as such:

Density = Mass / ( Final Volume - Initial Volume )

Density = 3.689 g / ( 8.54 mL - 7.29 mL )

Density = 3.689 g / ( 1.25 mL )

Density = 2.9512 g / mL

Hence, the density of the object is 2.9512 g / mL.

Cheers.
