The question is incomplete, here is the complete question:

The given chemical equation follows:

2H_2O\rightleftharpoons 2H_2+O_2

What is the equilibrium constant expression for the given system?

<u>Answer:</u> The expression of equilibrium constant for the given equation is K_{eq}=\frac{[H_2]^2[O_2]}{[H_2O]^2}

<u>Explanation:</u>

Equilibrium constant is the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

For a general chemical reaction:

aA+bB\rightleftharpoons cC+dD

The expression for K_{eq} is written as:  

K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}

The given chemical equation follows:

2H_2O\rightleftharpoons 2H_2+O_2

The expression for K_{eq} for above equation follows:

K_{eq}=\frac{[H_2]^2[O_2]}{[H_2O]^2}

Hence, the expression of equilibrium constant for the given equation is K_{eq}=\frac{[H_2]^2[O_2]}{[H_2O]^2}

Goshia [24]

Answer:

3.3 g of glucose, C6H12O6.

Explanation:

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

6CO2 + 6H2O —> C6H12O6 + 6O2

Next, we shall determine the mass of CO2 that reacted and the mass of C6H12O6 produced from the balanced equation.

This is illustrated below:

Molar mass of CO2 = 12 + (2x16) = 44 g/mol

Mass of CO2 from the balanced equation = 6 x 44 = 264 g

Molar mass of C6H12O6 = (12x6) + (12x1) + (16x6) = 180 g/mol

Mass of C6H12O6 from the balanced equation = 1 x 180 = 180 g

From the balanced equation above,

264 g of CO2 reacted to produce 180 g of C6H12O6.

Finally, we shall determine the mass of C6H12O6 produced by reacting 4.9 g of CO2 as follow:

From the balanced equation above,

264 g of CO2 reacted to produce 180 g of C6H12O6.

Therefore, 4.9 g of CO2 will react to produce = (4.9 x 180)/264 = 3.3 g of C6H12O6.

Therefore, 3.3 g of glucose, C6H12O6 were obtained from the reaction.

What functional feature(s) does the phosphate group contribute to the structure of a phospholipid? select all that apply. select
bezimeni [28]
A phospholipid structure is shown in the picture attached. It has three parts: the hydrophobic tail, the hydrophilic head and the phosphate group in the center. Thus, the function of the phosphate group is to link the hydrophobic and hydrophilic parts of a phospholipid. Specifically, the phosphate group is part of the hydrophilic head. So, it is used to connect the phospholipids to polar compounds.

The density of copper is 8.92 grams per milliliter. What volume of water will 40.0 grams of copper displace?
Klio2033 [76]

Density:

The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.

Density = mass in g / volume in cubic cm or ml

Given that  

Density = 8.92 g/ ml

Mass = 40.0 g

Therefore,  

Volume = mass/ density  

= 40.0 g/  8.92  g/ ml

= 4.48 ml  

Thus the correct answer is 4.48  ml
