The barometric pressure measured outside an airplane at 3 km ( ft) was 524 mmHg. Calculate the pressure in kPa.
NeX [460]

Answer:

69.8609 KPa.

Explanation:

The following data were obtained from the question:

Pressure (in mmHg) = 524 mmHg.

Pressure (in KPa) =?

Thus we can obtain the pressure in KPa as follow:

760 mmHg = 101.325 Kpa

Therefore,

524 mmHg = 524 mmHg × 101.325 KPa / 760 mmHg

524 mmHg = 69.8609 KPa

Thus, 524 mmHg is equivalent to 69.8609 KPa.

When both –NH2 and –COOH replace hydrogen atoms on the same carbon atom, a(n) ____ is formed. a. amine c. carboxylic acid b. ami
Mice21 [21]

-NH_{2} represents amine functional group and COOH represents carboxylic acid functional group. When these both functional groups are substituted onto a single carbon atom, then amino acid is formed.

The organic compound consists of -NH_{2} functional group and COOH functional group with a side chain is said to be an amino acid.

A: amine group is -NH_{2}.

C: carboxylic acid  group is COOH

B: amino acid represents -NH_{2} functional group and COOH functional group which are substituted onto a single carbon atom.

D: carbohydrate:  the general formula of carbohydrate is (CH_{2} O)_{x}.

Hence, amino acid is the correct answer.

Hydrogen is manufactured on an industrial scale by this sequence of reactions:
hichkok12 [17]

Answer:

K=K_1*K_2\\\\K=\frac{[H_2]^3[CO_2][H_2]}{[CH_4][H_2O][H_2O]}

Explanation:

Hello there!

In this case, for the given chemical reaction, it turns out firstly necessary to write the equilibrium expression for both reactions 1 and 2:

K_1=\frac{[CO][H_2]^3}{[CH_4][H_2O]} \\\\K_2=\frac{[CO_2][H_2]}{[CO][H_2O]}

Now, when we combine them to get the overall expression, we infer these two are multiplied to get:

K=K_1*K_2\\\\K=\frac{[CO][H_2]^3}{[CH_4][H_2O]} *\frac{[CO_2][H_2]}{[CO][H_2O]}\\\\K=\frac{[H_2]^3[CO_2][H_2]}{[CH_4][H_2O][H_2O]}

Regards!
