A chemical reaction that removes electrons from an atom is called "O<span>xidation".
The term came from late 18th century from French.
When the electrons are removed from an atom it increase its valence.</span>
Answer:
The energy of the photon is 1.718×10−26J.
Explanation:
The energy of the photon is
1.718 × 10 − 26J. You use the formula E =
, where h is Planck's Constant,c is the speed of light, and λ is the wavelength of the photon.
E==
= 1.718×10−26J.
Answer:
10 liters of the 1% solution and 8 liters of the 10% solution she should mix to make the 5% solution.
Explanation:
Let the volume of 1% acid solution used to make the mixture = x L
So, the volume of 10% acid solution used to make the mixture = y L
Total volume of the mixture = <u>x + y = 18 L .................. (1)</u>
For 1% acid solution:
C₁ = 1% , V₁ = x L
For 10% acid solution :
C₂ = 10% , V₂ = y L
For the resultant solution of sulfuric acid:
C₃ = 5% , V₃ = 18 L
Using
C₁V₁ + C₂V₂ = C₃V₃
1×x + 10×y = 5×18
So,
<u>x + 10y = 90 .................. (2)</u>
Solving 1 and 2 we get,
<u>x = 10 L</u>
<u>y = 8 L</u>
Thus,
<u>10 liters of the 1% solution and 8 liters of the 10% solution she should mix to make the 5% solution.</u>
1. It depends on your location. Relatively if you're facing north or south.
