Answer:

88.1 moles of H₂

Explanation:

Let's make the reaction:

H₂(g) + CO₂(g) → H₂O(g) + CO(g)

Ratio is 1:1

Therefore, 1 mol of hydrogen reacts with 1 mol of carbon dioxide to produce 1 mol of water and 1 mol of carbon monoxide.

In conclusion, 88.1 moles of water must be produced by 88.1 moles of H₂

The reaction can also be written as an equilbrium

H₂(g) + CO₂(g) ⇄ H₂O(g) + CO(g) Kc

If the volume of a confined gas is doubled while the temperature remain constant, what change (if any) would be observed in the

dimulka [17.4K]

The gas will obey Boyles Law:

P1 V1 = P2 V2 where P1 and V1 are the original pressure and volume and P2 and V2 are the new values.

If V2 = 2V1 (given) then:

P1 V1 = P2 *2 V1

P2 = P1 V1 / 2V1

P2 = P1 / 2

In other words the pressure is halved. (answer).

If I added 50 mL of a 1.0 M HCIO2 solution to 50 mL of a 1.0 M NaOH

kozerog [31]

Answer:

pH=7

Explanation:

0.05 L*1.0M= 0.05 mol HClO2 and 0.05 mol NaOH

HClO2 + NaOH ---> NaClO2 + H2O

0.05 mol 0.05 mol

As we can see acid and base react completely, solution will be neutral, so pH =7

What is the molarity of 60.0 grams of NaOH dissolved in 750 milliliters of water?

Bumek [7]

<u>Answer:</u>

The correct answer option is B) 2.0 M.

<u>Explanation:</u>

We are given the number of grams of NaOH (Sodium Chloride) which are dissolved in 750 milliliters of water and we are to find its molarity.

We know the formula of molarity:

<em>Molarity = (mass * 1000) / (volume * molecular mass) </em>

Volume = 750 ml = 750 cm $^3$

Molecular mass = 40

Mass = 60 grams

Substituting these values in the above formula:

Molarity = $\frac{(60*1000)}{750*40}$ = 2.0 M

a chemist adds of a calcium bromide solution to a reaction flask. calculate the mass in grams of calcium bromide the chemist has

mestny [16]

The mass of Calcium bromide added in the flask is 29.7 g.

<h3>What is Molarity? </h3>

Molarity is defined as the ratio of number of moles od solute to the number of volume of solution in litres.

Molarity = number of moles/ volume

<h3>Calculation of Moles</h3>

Number of moles = Molarity × volume

Given,

Molarity of Calcium bromide = 0.363 M

Volume of Calcium bromide = 410 mL

= 0.410L

By substituting all the value, we get

Number of moles = 0.363 × 0.410

= 0.148 mol

As we know that,

Molar mass of Calcium bromide = 199.89 g

Mole is defined as the given mass of substance to the molar mass of substance.

Given mass = Moles × Molar mass

= 0.148 × 199.89

= 29.75 g

= 29.7 g (significant digit)

Thus, we calculated that the mass of Calcium bromide added in the flask is 29.7 g.
