user100 [1]

Answer:

Option A is correct, there will be no N2 left in the flask

Explanation:

Step 1 : Data given

Number of moles of N2 = 135 mmol = 0.135 mol

Number of moles of H2 = 405 mmol = 0.405 mol

Step 2: The reaction

N2(g)+3H2(g)→2NH3(g)

Step 3:

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

Both will completely react. There is no limiting reactant.

There will be produce 0.270 moles NH3.

Option A is correct, there will be no N2 left in the flask

Which of the following statements is incorrect? Group of answer choices The product of wavelength and frequency of electromagnet
morpeh [17]

Answer: Option (b) is the correct.

Explanation:

It is known that energy is directly proportional to frequency.

Mathematically,              E \propto \nu

or,                           E = h \times \nu ............ (1)

where,     E = energy

                h = Plank's constant

              \nu = frequency

This relation shows that higher is the energy then more will be the frequency of electrmagnetic radiation.

Also,     \nu = \frac{c}{\lambda} ......... (2)

where,          c = speed of light

                 \lambda = wavelength

Therefore, substituting value of \nu from equation (2) into equation (1) as follows.

                 E = h \times \nu

                 E = h \times \frac{c}{\lambda}

This relation shows that higher is the energy then lower will be the wavelength.

Thus, we can conclude that as the energy of a photon increases, its frequency decreases, is incorrect statement.

What mass of water is required to react completely with 157.35 g CO2? (Molar mass of H2O = 18.02 g/mol; molar mass of CO2 = 44.0
Ghella [55]

You must use 64.43 g H₂O.

<em>Balanced chemical equation</em>: H₂O + CO₂ → H₂CO₃

<em>Moles of CO₂</em> = 157.35 g CO₂ × (1 mol CO₂/44.01 g CO₂) = 3.5753 mol CO₂

<em>Moles of H₂O</em> = 3.5753 mol CO₂ × (1 mol H₂O/1 mol CO₂) = 3.5753 mol Fe

<em>Mass of H₂O</em> = 3.5753 mol H₂O × (18.02 g H₂O /1 mol H₂O) = 64.43 g H₂O
