Answer:
The volume for the ideal gas is: 4647.5 Liters
Explanation:
Formula for the Ideal Gases Law must be applied to solve this question:
P . V = n . R . T
We convert the T° to K → 100°C + 273 = 373 K
We convert pressure value from kPa to atm.
2 kPa . 1atm/101.3 kPa = 0.0197 atm
We replace data in the formula.
V = ( n . R . T) / P → (3 mol . 0.082 . 373K) / 0.0197 atm =
The volume for the ideal gas is: 4647.5 Liters
(4) zinc
Explanation:
Given parameters:
Mass of the sample = 10g
Condition = STP
Unknown:
Element with the least volume = ?
Solution:
The number of moles of substance as STP can be derived using the equation below;
Volume of substance = number of moles x 22.4
Number of moles =
since mass = 10g
Number of moles of Al = = 0.37mole
Number of moles of Ti = = 0.29mole
number of moles of Mg = = 0.47mole
Number of moles of Zn = = 0.15mole
Zinc has the least number moles and it will have the lowest volume at STP because the volume directly proportional to number of moles.

Great amounts of atomic energy are released when
a _______reaction occurs.
Great amounts of atomic energy
are released when a chemical reaction occurs. The process can be an exothermic reaction
or endothermic reaction depending on the substances involved in the reaction.
Answer:
0.07
Explanation:
to find mole you divide mass by the relative atomic mass
Now you find the relative atomic of of moles pf he number sodium sulfide
then you thequation for finding moles to find mole of sodium
