Answer: 103.7 kPa
Explanation:
Given that:
initial volume of gas V1 = 445ml
initial pressure of gas P1 = 120 kPa.
new Volume V2 = 515ml
new pressure P2 = ?
Since, only pressure and volume are involved, apply the formula for Boyle's law
P1V1 = P2V2
120 kPa x 445ml = P2 x 515 kPa
53400 = P2 x 515 kPa
P2 = 53400/515
P2 = 103.7 kPa
Thus, the final pressure of the gas is 103.7 kPa
Answer:
Alcohol is a byproduct of the fermentation process, which takes place when the yeast converts the sugars derived from the grain. Knowing that, you can increase the alcohol by volume (ABV) by increasing the size of the grain bill or increasing the amount of malt extract used.
An ionic bond forms between a metal and a nonmetal. So, since C and O are nonmetals it cannot be that one. Also, P and Cl are also both nonmetals so it cannot be that one either. That leaves Li and O and Ca and Br. In an ionic bond metals loose electrons and nonmetals gain electrons. Therefore it cannot be Li and O because it states that oxygen, the nonmetal, looses electrons and lithium, the metal, looses electrons. So, the answer has to be Ca and Br because Ca, the metal, looses electrons and Br, the nonmetal, gains electrons.
The nucleus of an atom is made up of protons and neutrons. Then electrons circle around the nucleus.
Answer:
Proton, Neutron, Electron
