How do I solve this?
Xelga [282]

Answer:

Explanation:

When you divide exponentials, you subtract the powers. For the numbers infront, just use a basic calculator for.

7.95/6.02 = 1.32

10^22/10^23 = 10^-1

1.32 x 10^-1 is your answer

The decomposition of ammonia is: 2 NH3(g) = N2(g) + 3 H2(g). If Kp is 1.5 × 103 at 400°C, what is the partial pressure of ammoni
hjlf

Answer:

A) = 4.7 × 10⁻⁴atm

Explanation:

Given that,

Kp = 1.5*10³ at 400°C

partial pressure pN2 = 0.10 atm

partial pressure pH2 = 0.15 atm

To determine:

Partial pressure pNH3 at equilibrium

The decomposition reaction is:-

2NH3(g) ↔N2(g) + 3H2(g)

Kp = [pH2]³[pN2]/[pNH3]²

pNH3 =√ [(pH2)³(pN2)/Kp]

pNH3 = √(0.15)³(0.10)/1.5*10³ = 4.74*10⁻⁴ atm

K_p = \frac{[pH_2] ^3[pN_2]}{[pNH_3]^2} \\pNH_3 = \sqrt{\frac{(pH_2)^3(pN_2)}{pNH_3} } \\pNH_3 = \sqrt{\frac{(0.15)^3(0.10)}{1.5 \times 10^3} } \\=4.74 \times 10^-^4atm

= 4.7 × 10⁻⁴atm

Classify the following processes as exothermic or endothermic: (d) a person running;
Sonja [21]

The process releases energy and consequently we classify it as exothermic. (d) a person running releases warmness as muscle mass paintings. therefore, the procedure is exothermic.

d) Exothermic, heat is released as a person runs and muscle groups perform work.

A chemical response or bodily exchange is exothermic if warmth is released by using the system into the environment. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic procedure is -ve due to the fact the device is dropping heat.

Some other examples of exothermic reactions:

1)Snow Formation in Clouds.

2)Burning of a Candle.

3)Rusting of Iron.

4)Formation of Ion Pairs.

5)response of strong Acid and Water. etc...

Which of these substances acts as a buffer? <br> a. blood <br> b. lemon juice <br> c. curd
il63 [147K]
<span>The correct answer is( A) blood.

when the buffer solution its PH value changes very little when a small amount 

of strong acid or base is added to it, and here the bicarbonate buffering system is used to regular the PH of the blood that keeping the PH at nearly constant value by maintaining the original acidity or basicity of the solution.</span>
