Consider the following balanced reaction. How many grams of water are required to form 75.9 g of HNO3? Assume that there is exce
adoni [48]

Answer:

The answer is "10.84 g".

Explanation:

The formula for calculating the number for moles:

\text{Number of moles }= \frac{\ Mass}{ \ molar \ mass }

In the given acid nitric:

Owing to the nitric acid mass = 75.9 g

Nitric acid molar weight= 63\  \frac{g}{mol}

If they put values above the formula, they receive:

\text{moles in nitric acid} = \frac{75.9}{63}

                               =1.204 \ mol

In the given chemical equation:

3 NO_2 \ (g) + H_2O \ (l) \longroghtarrow 2 HNO_3 \ (aq) + NO\ (g)

In this reaction, 2 mols of nitric acid are produced by 1 mole of water.

So, 1.204 moles of nitric acid will be produced:

= \frac{1}{2} \times 1.204

=0.602\ \ \text{mol of water}.

We are now using Equation 1 in determining the quantity of water:

Water moles = 0.602\  mol

Water weight molar = 18.02 \ \frac{g}{mol}

\to 0.602 = \frac{\text{mass of mols}}{ 18.02}\\\\\to \text{mass of mols} = 0.602 \times 18.02\\\\

                         =10.84 \ g

In the Haber process, 30.00 g of nitrogen gas is combined with 30.00 g of hydrogen gas to form ammonia gas, NH3. What mass, in g
noname [10]

Answer:

Mass = 36.38 g

Explanation:

Given data:

Mass of hydrogen = 30.0 g

Mass of nitrogen = 30.0 g

Theoretical yield of reaction = ?

Mass of ammonia = ?

Chemical equation:

N₂+ 3H₂  → 2NH₃

Number of moles of N₂:

Number of moles  = Mass /molar mass

Number of moles = 30 g / 28 g/mol

Number of moles = 1.07 mol

Number of moles of H₂:

Number of moles = Mass /molar mass

Number of moles = 30 g / 2g/mol

Number of moles = 15 mol

Now we will compare the moles of NH₃ with hydrogen and nitrogen .

                 H₂             :                 NH₃

                 3               :                 2

                15              :                2/3×15= 10 mol

                 N₂             :                 NH₃

                 1                :                  2

               1.07             :               2 × 1.07= 2.14 mol

The number of moles of NH₃ produced by nitrogen are less it will be limiting reactant.

Mass of ammonia:

Mass of NH₃  = moles × molar mass

Mass =2.14 mol × 17 g/mol

Mass = 36.38 g

WARRIOR [948]

Answer: 1. A. testable

2.new observations

Explanation:

A scientific theory is the one which explains the cause of a natural phenomena through observatory and experimentation approach. It is valid, accurate and acceptable worldwide.

1. It is testable by implementation of suitable methodology for the purpose of proving the cause of the natural phenomena occurring in nature.

2. A the explanation of the theory can be changes on the basis of the new observations obtained after implementation of new technology and methodology.
