For each of the following balanced chemical equations, calculate how many moles and how many grams of each product would be prod
anastassius [24]

Answer : The number of moles of NH_4Cl and mass of NH_4Cl is 0.50 mole and 27 grams respectively.

Solution : Given,

We are assuming that the reactant indicated in boldface is NH_3. So,

Moles of NH_3 = 0.50 mole

Molar mass of NH_4Cl = 53.5 g/mole

First we have to calculate the moles of NH_4Cl

The balanced chemical reaction is,

NH_3(g)+HCl(g)\rightarrow NH_4Cl(s)

From the reaction, we conclude that

As, 1 mole of NH_3 react to give 1 mole of NH_4Cl

So, 0.50 moles of NH_3 react to give 0.50 moles of NH_4Cl

The number of moles of NH_4Cl  is, 0.50 moles.

Now we have to calculate the mass of NH_4Cl

\text{ Mass of }NH_4Cl=\text{ Moles of }NH_4Cl\times \text{ Molar mass of }NH_4Cl

\text{ Mass of }NH_4Cl=(0.50moles)\times (53.5g/mole)=26.75g\approx 27g

The mass of NH_4Cl  is, 27 grams.

What is the energy of a single photon of blue light with a wavelength of 488 nm (488 × 10-9 m)?
Vinvika [58]
E = hf

c = speed of electromagnetic wave, c ≈ 3 * 10⁸ m/s, 
Planck's constant h = 6.63 *10⁻³⁴ Js

h = Planck's constnat,  Frquency, f = c/λ = (3*10⁸)/(488*10⁻⁹)

E = hf

E = hc/λ

E = (6.63 * 10⁻³⁴ * 3 * 10⁸) /(488 * 10⁻⁹)

Energy, E ≈ 4.0758 * 10⁻¹⁹  Joules.

NaOH (aq) + HCl(aq) => NaCl(aq)+ H2O(l)

Na+(aq)+ OH - (aq) + H +(aq) +Cl - (aq) + Cl- (aq)
=> Na+(aq) + Cl - (aq) + H2O(l)
H+(aq) + OH-(aq) => H2O(l)
