Answer:
The correct answer is being authoritative.
Explanation:
Authoritative refers to permission to act without asking permission while being held responsible. While implementation refers to the conclusion of all the work in solving an issue and needs careful consideration to detail. There are three fundamental steps involved, that is, preparing and planning to implement the solution, implementing and observing the activity, and evaluating and studying the success of the action. Thus, in my opinion being authoritative would be a primary concern when implementing a solution.
2 moles
3 moles
6 moles
Answer:
Moles of gas added = 3 moles
Explanation:
Given:
Initial volume of gas, V1 = 2.0 L
Initial moles of gas, n1 = 3 moles
Final volume, V2 = 4.0 L
To determine:
The moles of gas added to bring the final volume to 4.0 L
Explanation:
Based on the ideal gas equation
where P = pressure, V = volume ; n = moles of gas
R = gas constant, T = temperature
At constant P and T, the above equation becomes:
V/n = constant
This is the Avogadro's law
Therefore:
The final number of moles of gas = 6
Thus, moles added = Final - Initial = n2 - n1 = 6-3 = 3 moles
B) 1:2
C)2:1
D)3:1
Answer:
Option A = 1:1
Explanation:
The atoms of calcium and sulphur when react their ration is 1:1. The charge on calcium is +2 and on sulphur is -2.
Ca⁺²S⁻²
The +2 and -2 charges are cancel out and overall charge will be zero.
CaS
so their atomic ratio will be 1:1
