Heat of vaporization of water will be required as water is already at it's boiling point thus heat required will be 540*10=5400 cal

Which general equation shows a Single-displacement reaction?

Stella [2.4K]

Hello! The answer is D

A good note for these is when there are three elements, one being a singular element and another a compound and there’s a single switch, this could show a single-displacement

Have a good day gamer.

A gas mixture contains HBr, NO2, and C2H6 at STP.If a tiny hole is made in the container, which gas will effuse fastest?Which ga

MakcuM [25]

Explanation:

Molar mass of HBr = 81 g/mol

Molar mass of nitrogen dioxide gas = 46 g/mol

Molar mass of ethane = 30 g/mol

Graham's Law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

$\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}$

So, the gas with least molar mass will effuse out fastest from the container and that is ethane gas.

The formula for average kinetic energy is:

$K.E=\frac{3}{2}kT$

where,

k = Boltzmann’s constant = $1.38\times 10^{-23}J/K$

T = temperature = 273.15 K ( at STP)

As we can see from the formula that kinetic energy depends upon only temperature of the gas molecule.

So, from this we can say that all the gas molecules have the same average kinetic energy at this temperature.

How is nuclear energy generated?

balandron [24]

Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. ... In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant.

Karo-lina-s [1.5K]

Answer: The strange liquid would float to the top of a cup of water.

Explanation:

Density = Mass/Volume

Strange Liquid Density = 70g/84mL

Strange Liquid Density = 0.833g/mL

Density of water in g/mL = 1 g/mL

Strange Liquid Density < Water Density

A substance with a lower density would be suspended above a substance with a higher density.

Since the density of the strange liquid is less than that of water, it would float to the top of a cup of water.
