LED light bulb is more energy efficient than CFL bulb simply because they are based on better technology. LED light bulbs use much lesser energy in comparison to the traditional technology.
Answer:
1072 torr
Explanation:
To answer this problem we can use <em>Gay-Lussac's law</em>, which states:
Now we convert the given temperatures into K:
- T₁ = 15°C ⇒ 15+273.16 = 288.16 K
- T₂ = 36°C ⇒ 36+273.16 = 309.16 K
We <u>input the data</u>:
- 1000 torr * 309.16 K = P₂ * 288.16 K
And <u>solve for P₂</u>:
Answer:
6
Explanation:
Li has an oxydation number of 1 2*1 = 2
O has an oxidation number of -2 4(-2) = -8
S has an oxydation number of x 1 * x = x
The oxidation number on the molecule is 0.
So here is the equation
2 - 8 + x = 0 Combine like terms
-6 + x = 0 Add 6 to both sides
-6 + 6 + x = 6 Combine like terms
x = 6
Sulphur in this case has an oxidation number of 6
Answer: The salt which has the highest pH is 
Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:
The given salts are formed from the reaction of acids and bases.
1) 
This is a salt formed by the reaction of strong base (KOH) and strong acid 
. So, this salt is a neutral salt.
2) 
This is a salt which is formed by the reaction of weak base 
and strong acid . So, this salt is an acidic salt.
3) 
This is a salt which is formed by the reaction of weak base 
and strong acid (HCl). So, this salt is an acidic salt.
4)
This is a salt which is formed by the reaction of strong base (NaOH) and weak acid 
. So, this salt is a basic salt.
Now, we have to find the salt which has the highest pH value.
Highest pH value means that the salt must be basic in nature and from the given salts, only is basic salt. Hence, this salt has the highest pH value.
