The amount of oxygen in grams that reacted with 5.6 g of hydrogen to produce 41.4 g of water is 36.8 g

<h3>Balanced equation </h3>

2H₂ + O₂ —> 2H₂O

Molar mass of O₂ = 32 g/mole

Mass of O₂ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = 18 g/mole

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

SUMMARY

From the balanced equation above,

36 g of H₂O was produced from 32 g of O₂

NOTE: O₂ is the limiting reactant

<h3>How to determine the mass of oxygen required</h3>

From the balanced equation above,

36 g of H₂O was produced from 32 g of O₂

Therefore,

41.4 g of H₂O will be produced from = (41.4 × 32) / 36 = 36.8 g of O₂

Thus, 36.8 g of O₂ reacted to produce 41.4 g of H₂O

An analogy is the closest way to compare something to another that may not be related so that would be my pick. If that’s not it I guess he could maybe be making an observational opinion about it? Good luck hope this helped. Analogy

Calculate the value of [CH3OH][CO][H2]2 when all concentrations are 2.4. Keep in mind that the reaction may not be at equilibriu

NikAS [45]

Explanation:

The given reaction will be as follows.

$CO + 2H_{2} \leftrightharpoons CH_{3}OH$

So, equilibrium constant for this equation will be as follows.

$K_{c} = \frac{[CH_{3}OH]}{[CO][H_{2}]^{2}}$

As it is given that concentration of all the species is 2.4. Therefore, calculate the value of equilibrium constant as follows.

$K_{c} = \frac{[CH_{3}OH]}{[CO][H_{2}]^{2}}$

= $\frac{2.4}{2.4 \times (2.4)^{2}}$

= 0.173

Thus, we can conclude that equilibrium constant for the given reaction is 0.173.

Answer:

HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)

Explanation:

From the question given above

HNO₃ + H₂O —> ?

Nitric acid, HNO₃ reacts with water, H₂O to form aqueous solution of nitric acid as illustrated below:

HNO₃ + H₂O —> HNO₃ (aq)

Nitric acid is a strong acid and, so will ionised completely when dissolved in water. This is illustrated below:

HNO₃ (aq) —> H⁺ (aq) + NO₃¯ (aq)

When an atom gains an electron to become an ion what happens to its size?

irina [24]

It stays roughly the same size. Electrons have a barely imperceptible mass so the overall mass of the atom is changed very little.
