Answer:
615 g
Explanation:
In order to convert from moles of any given substance into grams, we have to use said substance's <em>molar mass</em>, as follows:
- # moles * Molar mass = grams of substance.
Thus, we now <u>calculate the molar mass of beryllium iodide</u>, BeI₂, using the <em>molar masses of the elements</em>:
- Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol
Finally we <u>calculate how many grams are there in 2.34 moles of BeI₂</u>:
- 2.34 mol * 262.821 g/mol = 615 g
Well weathering adds different elements to rocks which they might not be used to. For example, very hard rain & harsh winds could push a rock, causing it to fall & break off into smaller rocks.

Answer:
There is no friction because of the mass.
Explanation:
The bigger box ran out of force to move so it hit the smaller box. (im in 7th grade and have the answer key)
Answer:
Increase the pressure of the gas
Explanation:
According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).
From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.
When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.
