To make an electron jump into a higher level we basically need to provide them with the energy. This energy can be provided by heating or by striking the potassium surface with a high frequency monochromatic wave of light.
N2 + 3H2 = 2NH3
in this question, we are dealing with only NH3 and H2 so we only focus on that
since the ratio of H2 to 2NH3 is 3:2, we say that
3 liters of H2 = 2 liters of 2NH3
3.6 litres of H2 = x liters of 2NH3
We cross multiple to give:
3 × x = 3.6 × 2
3x = 7.2
Divide both sides by 3
x = 7.2 ÷ 3
x = 2.4liters
Hi!
<u>Answer: 1ml of NaOH and 49 ml of Water</u>
Concentration of NaOH to make: 0.001 M ( C1 )
Volume of NaOH to make: 50 ml ( V1 )
Concentration of NaOH in stock: 0.05 M ( C2 )
Volume of stock to use: V2
Using the formula C1 V1 = C2 V2 which is the standard formula for determining the dilutions to acquire a specified volume and concentration, we get:
0.001 M x 50 ml = 0.05 M x V2
V2 = 1 ml
<em>So using 1ml of 0.05 M NaOH and 49 ml of Water</em>
<h3>Hope this helps</h3>
Answer:
I might be wrong but i believe the answer would be A.
Explanation:
I think its A. because:
The unified cell theory states that all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
