How many moles of NH3 will be produced if 2 moles of N2 reacts with excess H2 gas?

skad [1K]

Answer:

2 moles of N₂ will produce 4 moles of NH₃

Step-by-step explanation:

Equation of reaction

N₂ + 3H₂ → 2NH₃

The process above is the Born-Harber method of producing ammonia NH₃ industrially.

From the equation of reaction,

1 moles of N₂ will produce 2 moles of NH₃

1 moles N₂ = 2 moles NH₃

2 moles of N₂ = x moles of NH₃

x = (2*2) / 1 = 4moles of NH₃

2 moles of N₂ will produce 4 moles of NH₃

Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual int

taurus [48]

Answer:

You should choose an account with a 7% annual interest rate which is compounded quarterly

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

part 1)

we have

$t=15\ years\\ P=\$14,000\\ r=0.07\\n=4$

substitute in the formula above

$A=14,000(1+\frac{0.07}{4})^{4*15}$

$A=14,000(1.0175)^{60}$

$A=\$39,645.43$

part 2)

we have

$t=15\ years\\ P=\$14,000\\ r=0.068\\n=12$

substitute in the formula above

$A=14,000(1+\frac{0.068}{12})^{12*15}$

$A=14,000(1.0057)^{180}$

$A=\$38,713.11$
