Answer:

To increase the yield of H₂ we would use a low temperature.

For an exothermic reaction such as this, decreasing temperature increases the value of K and the amount of products at equilibrium. Low temperature increases the value of K and the amount of products at equilibrium.

Explanation:

Let´s consider the following reaction:

CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)

When a system at equilibrium is disturbed, the response of the system is explained by Le Chatelier's Principle: <em>If a system at equilibrium suffers a perturbation (in temperature, pressure, concentration), the system will shift its equilibrium position to counteract such perturbation</em>.

In this case, we have an exothermic reaction (ΔH° < 0). We can imagine heat as one of the products. If we decrease the temperature, the system will try to raise it favoring the forward reaction to release heat and, at the same time, increasing the yield of H₂. By having more products, the value of the equilibrium constant K increases.

How many cm 3 are in 0.014 in 3? (1 in = 2.54 cm)
pashok25 [27]

Answer:

0.229 cm³.

Explanation:

The following data were obtained from the question:

Volume (in in³) = 0.014 in³

Volume (in cm³) =?

1 in = 2.54 cm

Next, we shall determine a conversion scale to convert from in³ to cm³. This can be obtained as follow:

1 in = 2.54 cm

Therefore,

1 in³ = 2.54³ cm³

1 in³ = 16.387 cm³

Finally, we shall convert 0.014 in³ to cm³. This can be obtained as follow:

1 in³ = 16.387 cm³

Therefore,

0.014 in³ = 0.014 in³ × 16.387 cm³ / 1 in³

0.014 in³ = 0.229 cm³

Thus, 0.014 in³ is equivalent to 0.229 cm³.

The molecular formula HOH is an example of a(n)
vodka [1.7K]

Molecule

Explanation:

The molecular formula HOH is an example of a molecule.

A molecule is the smallest particle of a substance (element or compound) capable of independent existence.

Molecules can be:

  1. Monoatomic with one atom e.g Neon, Argon
  2. Diatomic with two atoms e.g Nitrogen gas N₂
  3. Polyatomic e.g ozone O₃

The word molecule can also be used to refer to a covalent compound that has discrete or separate units.

The formula HOH or H₂O is a separate covalent that has an independent existence.

How large a volume is need to contain 21 grams of silver? (info: density of silver is 10.5)
Ksivusya [100]
<span>Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate the volume as follows:

21 grams Ag ( 1 L / 10.5 grams ) = 2 L of container is needed for the given mass of silver

Hope this answers the question. Have a nice day. </span>

Determine the number of grams in 4.87 x 10^22 atoms of barium hydroxide Ba(OH)2'
taurus [48]

Answer:

hola espero que mi respuesta ayude

Explanation:

The  concentration   of  hydroxide ion  (-OH)  in  1.37 x10^-5 m solution  of Ba(OH)2  is  calculated  as   follows

write   the  equation  for  dissociation  of Ba(OH)2

Ba(OH)2 =  Ba^2+(aq)   + 2OH^-(aq)

by use  of  mole  ratio between Ba(OH)2 to OH^-  which   is  1:2  the   concentration  of OH^-  =  2x  ( 1.37 x10^-5) = 2.74  x10^-5 M
