Answer:
Ba,Sr,Ca,Be
Explanation:
as atomic size increases ionisation potential decreases
Explanation:
12.0 mol KClO3 × (3 mol O2/2 mol KClO3)
= 18.0 mol O2
Answer:
Number of moles of chlorine = 3.38 mol
Explanation:
Given data:
Mass of chlorine = 120 g
Moles of chlorine = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of chlorine = 35.5 g/mol
Now we will put the values in formula.
Number of moles = 120 g/ 35.5 g/mol
Number of moles = 3.38 mol
The given question is incomplete. The complete question is:
A gas has a volume of 590 ml at a temperature of
.What volume will the gas occupy at
. Which gas law is this?
Answer: 655 ml , Charle's Law
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume at
is 655 ml
