Answer:
C. liquid to a gas
Explanation:
I know this is right but I don't have an explanation
Answer:
Explanation:
If it is said that an electric bulb contains 60 watts, that implies that the electric bulb will have to consume a required amount of energy of about 60 joules in a second.
Mathematically:
Power rating = Energy consumed ÷ time
The electronic configuration typically implies the arrangement of electrons in atomic orbitals. The electronic configuration of Calcium (Ca) in it subshell method is:

Answer: The reaction will shift in left or backward direction.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:

As the given reaction is exothermic as the heat is released in the reaction. When the temperature is raised , the reaction will shift in a direction where temperature is decreasing and that is the reverse reaction which is endothermic in nature.
Thus the reaction will shift in left or backward direction.

i. The new concentration is 0.116 M
ii. The new concentration is 0.029 M
<h3>What is the concentration of the original hydrochloric acid acid?</h3>
The concentration of the original or stock hydrochloric acid is calculated as follows:
- Molarity = Percentage concentration * Density * 1000/Molar mass * 100
Molarity of stock HCl = 36 * 1.18* 1000 /36.5 * 100
Molarity of stock HCl = 11.6 mol/dm
i. Using the dilution formula: M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 11.6 * 10/1000
M₂ = 0.116 M
The new concentration = 0.116 M
ii. Using M₁V₁ = M₂V₂
M₂ = M₁V₁ /V₂
M₂ = 0.116 * 5/20
M₂ = 0.029 M
The new concentration = 0.029 M
In conclusion, the new concentrations are found using the dilution formula.
