If you are given 64.0 grams of CH4, how many grams of H2O are made

IrinaVladis [17]

Answer:

144 g of H₂O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:

Molar mass of CH₄ = 12 + (4×1)

= 12 + 4 = 16 g/mol

Mass of CH₄ from the balanced equation = 1 × 16 = 16 g

Molar mass of H₂O = (2×1) + 16

= 2 + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY:

From the balanced equation above,

16 g of CH₄ reacted to produce 36 g of H₂O.

Finally, we shall determine the mass of H₂O produced by the reaction of 64 g of CH₄. This can be obtained as follow:

From the balanced equation above,

16 g of CH₄ reacted to produce 36 g of H₂O.

Therefore, 64 g of CH₄ will react to produce = (64 × 36)/16 = 144 g of H₂O.

Thus, 144 g of H₂O were obtained from the reaction.

Isoleucine, leucine, and lysine are three examples of amino acids that the body can not make in sufficient quantity. How are the

Natalija [7]

Answer:

Leucine, isoleucine and lysine are classified as <u>essential amino acids.</u>

Explanation:

Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.

The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).

There are total <u>21 amino acids in a human body</u>.<em><u> They can be divided into two types: Essential amino acids and Nonessential amino acids</u></em>

Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.

<u>Example: leucine, isoleucine, lysine.</u>

<u>Therefore, leucine, isoleucine and lysine are classified as essential amino acids.</u>

Answer:

* $W=1142.86Joule$

* $Q=997.7J$

* $H=2140.5J$

Explanation:

From the question we are told that:

Temperature $T=337K$

Pressure $P=(60-55)Pa*10^5$

Volume $V=(1.6-1.4)m^3*10^{-3}$

Generally the equation for gas Constant is mathematically given by

$\frac{P_2}{P_1}=\frac{V_1}{V_2}^n$

$\frac{55*10^5}{60*10^5}=\frac{1.4*10^{-3}}{1.6*10^{-3}}^n$

$n=0.65$

Therefore

Work-done

$W=\int{pdv}$

$W=\frac{55*10^5*1.6*10^{-3}*60*10^5*1.4*10^{-3}}{1-0.65}$

$W=1142.86Joule$

Generally the equation for internal energy is mathematically given by

$Q=mC_vdT\\\\Q=\frac{3*1*3.314*16}{1.4-1}$

$Q=997.7J$

Therefore

$H=Q+W$

$H=997.7J-11.42.9$

$H=2140.5J$
