Answer:

35.3124 g is the maximum mass of $H_2O$ that can be produced.

Explanation:

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

For $NH_3$ :-

Mass of $NH_3$ = 52.3 g

Molar mass of $NH_3$ = 17.031 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{52.3\ g}{17.031\ g/mol}$

$Moles\ of\ NH_3= 3.0709\ mol$

For $O_2$ :-

Given mass of $O_2$ = 52.3 g

Molar mass of $O_2$ = 31.9898 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{52.3\ g}{31.9898\ g/mol}$

$Moles\ of\ O_2=1.6349\ mol$

According to the given reaction:

$4NH_3+5O_2\rightarrow 4NO_4+6H_2O$

4 moles of $NH_3$ reacts with 5 moles of $O_2$

1 mole of $NH_3$ reacts with 5/4 moles of $O_2$

Also,

3.0709 moles of $NH_3$ reacts with $\frac{5}{4}\times 3.0709$ moles of $O_2$

Moles of $O_2$ = 3.8386 moles

Available moles of $O_2$ = 1.6349 moles

Limiting reagent is the one which is present in small amount. Thus, $O_2$ is limiting reagent.

The formation of the product is governed by the limiting reagent. So,

5 moles of $O_2$ on reaction forms 6 moles of $H_2O$

1 mole of $O_2$ on reaction forms 6/5 moles of $H_2O$

Thus,

1.6349 mole of $O_2$ on reaction forms $\frac{6}{5}\times 1.6349$ moles of $H_2O$

Moles of $H_2O$ = 1.9618 moles

Molar mass of $H_2O$ = 18 g/mol

Mass of sodium sulfate = Moles × Molar mass = 1.9618 × 18 g = 35.3124 g

35.3124 g is the maximum mass of $H_2O$ that can be produced.

N which parts of the cell cycle would chromosomes be paired up? Check all that apply.

Kitty [74]

Answer:

The correct option es interphase

Explanation:

The interface is a stage of the cell division where a lot of energy is demanded, and it is the longest of the entire cycle.

This is because it is here where the duplication of the genetic load is generated, that is, of the chromosomes.

The chromosomes reach the cell poles and this is how a contraction begins to appear in the middle of the cell, it is essential to clarify that the interface not only requires energy but also occupies 95% of the cell division.

What is the speed of a man that travels 2 meters in 6.5 seconds?

sergij07 [2.7K]

Answer:

0.305556 m / s

Explanation:

Speed = distance / time

2 metres = 0.002 km

6.5 sec = 0.00180556 hrs

Therefore,

Speed = 0.002 / 0.00180556

= 1.1 km / hr

= 0.305556 m / s

in order to find the molar mass of an unknown compound, a research scientist prepared a solution of 0.930 g of an unknown in 125

PtichkaEL [24]

Answer:

Molar mass→ 0.930 g / 6.45×10⁻³ mol = 144.15 g/mol

Explanation:

Let's apply the formula for freezing point depression:

ΔT = Kf . m

ΔT = 74.2°C - 73.4°C → 0.8°C

Difference between the freezing T° of pure solvent and freezing T° of solution

Kf = Cryoscopic constant → 5.5°C/m

So, if we replace in the formula

ΔT = Kf . m → ΔT / Kf = m

0.8°C / 5.5 m/°C = m → 0.0516 mol/kg

These are the moles in 1 kg of solvent so let's find out the moles in our mass of solvent which is 0.125 kg

0.0516 mol/kg . 0.125 kg = 6.45×10⁻³ moles. Now we can determine the molar mass:

Molar mass (mol/kg) → 0.930 g / 6.45×10⁻³ mol = 144.15 g/mol
