Answer: b) Doppler Effect

Explanation:

Line broadening in AAS, arises due to some effects, which can occur due to a number of factors. The line width broadening effects include: Doppler, Lorentz, Self absorption, and quenching effects.

Doppler effect arises because along the line of observation, atoms will have different components of velocity.

A gas is confined in a 0.3m diameter cylinder by a piston, on which rests a weight. The mass of the piston is 85 kg. The local a
iris [78.8K]

Explanation:

Force applied on the gas will be as follows.

                   F_{gas} = F_{atm} + (m + M) g

As,   F = pressure × area. Hence, calculate the forces as follows.

                  F_{gas} = pressure × area

                         = 1.4 \times 10^{5} Pa \times \pi \times (\frac{0.3}{2})^{2}

                          = 1.979 \times 10^{4} N

                  F_{atm} = pressure × area

                            = 1.0133 \times 10^{5} \times \pi \times (\frac{0.3}{2})^{2}

                            = 1.432 \times 10^{4} N

      F_{gas} - F_{atm} = 5.47 \times 10^{3} N

Substituting the calculated values into the above formula as follows.

                F_{gas} = F_{atm} + (m + M) g

              F_{gas} - F_{atm} = (m + M) g

              5.47 \times 10^{3} N = (m + 85) \times 9.8    

              5.47 \times 10^{3} N = 9.8m + 833

                               m = 472.76 kg

Thus, we can conclude that the mass is 472.76 kg.

Ammonia gas and oxygen gas react to form water vapor and nitrogen monoxide gas. What volume of water would be produced by this r
NikAS [45]

Answer:

Water volume produced is 7.3 mL

Explanation:

This the reaction:

4NH₃ (g) + 5O₂ (g) →  4NO (g) + 6H₂O (g)

We have to work with density, to solve this question

Density of ammonia = Ammonia mass / Ammonia volume

0,00073 g/mL = Ammonia mass / 6300 mL

(Notice, we had to convert 6.3L to mL)

0.00073 g/mL . 6300 mL = Ammonia mass → 4.599 g

Mass / Molar mass = Mol

4.599 g / 17g/m = 0.270 mole

Ratio is 4:6

4 mole of ammonia produce 6 mole of water

0.270 mole produce (0.270  .6)/4 = 0.405 mol

Molar mass . mole = mass

18 g/m . 0.405 m = 7.30 g

Water density = 1 g/mL

Water density = Water mass / Water Volume

1g/mL = 7.30 g / Water volume

Water volume = 7.3 mL

Which of the following has the smallest radius Rb+, K, K+, or Rb+
Stells [14]
The trend of elemental radius increases from top to bottom and from right to left. This means Rb is greater than K. Incorporating the positive charges, K+ is smaller than K and Rb+ is smaller than Rb. Thus, the trend in increasing order is K+,K,Rb+,Rb.
