Answer : The correct answer is 2.36 mol of gold
1 mole of any element have 6.022 x 10²³ number of atoms ( Avogadro's number).
So the formula relating mole and number of atoms is given as :
Plugging value in formula :
Mole of gold = 2.36 mol
Answer:
the temprtaur of the gassssss
Explanation:
4) the equation for Boyle’s law is P1V1 = P2V2 meaning that pressure is inversely proportional to the volume (when one increases the other decreases)
5) We know that pressure is inversely proportional to the volume when temperature is constant. So if volume was decreased the pressure would increase. In this situation the gas was shifted to a tank with less volume from 5L to 1L, so the pressure will be increased by a factor of 5x.
6) (325 x 1)/0.25 = 1300kPa is the pressure inside of the piston chamber
Answer:
C: They are highly reactive
Explanation:
The elements on the left side of the table are mostly metals except for hydrogen. And most metals are highly reactive.
