Answer:
A. volume
Explanation:
Generally the equation for the ideal gas is mathematically given as
PV=nRT
Where
P=pressure
V=volume
R=gas constant
n=Number of Moles
T=Temperature
Therefore
V=nRT/P
Option A

That’s wrong it is a physical change. And that is because only the states are being changed. No bonds are broken or made during this inside the actual compound.
Answer:
P(total) = 3360 psi
Explanation:
According to the Dalton law of partial pressure:
The pressure of gas is sum of the partial pressure of each components.
P(total) = P₁ + P₂ + P₃ +.... + Pₙ
Given data:
Partial pressure of CO = 2235 psi
Partial pressure of CO₂ = 1125 psi
Total pressure = ?
Solution:
P(total) = P(CO) + P (CO)
P(total) = 2235 psi + 1125 psi
P(total) = 3360 psi
Explanation:
kclo3- 39+35.5+16*3=122.5
molar mass = 122.5
mass = 14.0g
volume= 100cm3
solubility in mol/dm3 or molarity = ?
but we know that
no of moles = solubility in mol/dm3×vol in cm3
---------------------------------------------
1000
no of moles = mass
---------
molar mass
mass\molar mass= solubility in mol/dm3 *vol in cm3/ 1000
14.0/122.5=x * 100/1000
solubility =0.875 mol/dm3
Answer:
An atom of ¹¹⁸Xe contains 64 neutrons.
Explanation:
Number of Protons:
The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Xenon is 54 therefore, it contains 54 protons.
Number Neutrons:
The number of neutrons present in atom are calculated as,
# of Neutrons = Atomic Mass - # of protons
As given,
Atomic Mass = 118
# of Protons = 54
So,
# of Neutrons = 118 - 54
# of Neutrons = 64
