<h2>Answer:</h2>
It means the waves collides and constructive interference occurred.
<h3>Explanation:</h3>
If the two waves coming from the opposite direction collide with each other, there are two way of their interference.
- Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
- Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.
Hence in experiment there will be constructive interference.
Answer:
from 10-14
Explanation:
the pH of potassium hydroxide is extremely high and is a strong base although the exact value depends on the concentration of the base in water.
Answer:
E.
Explanation:
Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.
At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.
ABC are reactants their concentration should decrease over time
DE are products, they should increase as reaction goes on.

Explanation:
This is because oganesson is a noble gas and element of group 18 which does not occur or is not produced naturally. It is produced in an experiment. It is a gas at room temperature and it has atomic number of 118. It is harmful and a radioactive gas due to it's radioactive properties and it is produced in small amound
Answer:
Answer: Kp = 4.5
Explanation:
The balanced equation for the production of synthetic gas is
CH4 + H20 ⇒ CO + 3H2
Let x be the change in the concentration of each species at equilibrium
CH4 + H20 ⇔ CO + 3H2
Initial 0.60 2.6 0 0
Change -x -x +x +3x
Equilibrium 0.60-x 2.6-x x 3x
Given that the equilibrium partial pressure of H2= 1.4 atm
then, 3x= 1.40
x= 1.4/3 = 0.466667
The equilibrium concentrations are
{CH4} = 0.60- x = 0.60 - 0.466667 = 0.133333atm
{H2O} = 2.60- x = 2.60 - 0.466667 = 2.133333atm
{CO} = x = 0.466667atm
{H2} = 1.4atm (given)
Kp = <u>{CO}{H2}³</u>
{CH4}{H2O}
Kp = <u>(0.466667)(1.4)³</u>
(0.133333)(2.133333)
= 4.501875
Kp = 4.5
