Answer:
FV = $3506.112
Interest = $506.112
Explanation:
We are given;
Annual deposit; A = $1000
Interest rate; i = 8% = 0.08
Number of years; n = 3
The value of the annuity after 3 years will be gotten from the formula;
FV = A[((1 + i)ⁿ - 1)/i](1 + i)
FV = 1000(((1 + 0.08)³ - 1)/0.08)(1 + 0.08)
FV = 1000(1.08⁴ - 1.08)/0.08
FV = $3506.112
Since you deposited $1000 each year, then after 3 years, total deposited = 3 × 1000 = $3000
Since FV = $3506.112, then interest = $3506.112 - $3000
Interest = $506.112
Answer:
33.95 grams of NaN3
Explanation:
Number of moles of NaN3 = mass (m)/MW = m/65 mole
I mole of NaN3 requires 22.4L air bag
m/65 mole of NaN3 required 11.7L
22.4m/65 = 11.7
22.4m = 65×11.7
22.4m = 760.5
m = 760.5/22.4 = 33.95grams of NaN3
Answer: Option (C) is the correct answer.
Explanation:
According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, 
.
For example, 
Arrhenius acids are the species which when dissolved in water will give hydrogen ions, that is, 
.
For example, 
In water, when an acid loses a hydrogen ion then the specie formed is known as conjugate base.
Here, 
is the conjugate base of 
.
Similarly, species which accept the hydrogen ion result in the formation of conjugate acid.
Hence, 
is the conjugate acid of 
.
Thus, we can conclude that is the conjugate base.
