Answer:The new volume is 5mL
Explanation:
The formular for Boyles Law is; P1 V1 = P2 V2
Where P1 = 1st Pressure V1 = First Volume
P2 = 2nd Pressure V2 = Second Volume
From the question; P1 = 5atm, V1 = 10ml
P2 = 2 x P1 (2 x 5) = 10 atm V2 =?
Using the Boyles Law Formular; P1 V1 = P2 V2, we make V2 the subject of formular; P1 V1/ P2 = V2
∴ 5 x 10/ 10 = 5
∴ V2 = 5mL

Answer:
129,66 g
Explanation:
Desde,
Número de moles = concentración * volumen
concentración = 2 M
volumen = 875 ml
Número de lunares = 2 * 875/1000
Número de lunares = 1,75 moles
Número de moles = masa / masa molar
masa molar de hidróxido de calcio = 74.093 g / mol
1,75 moles = masa / 74,093 g / mol
masa = 1,75 moles * 74,093 g / mol
masa = 129,66 g
<span>Oxygen is a colorless, odorless, tasteless
gas; it is the first member of Group 16 of the periodic table. It is
denser than air and only slightly soluble in water. A poor conductor of heat and electricity, oxygen supports combustion but does not burn.</span>
