Answer:

The electromagnetic force is a long range force which acts of charged particles. Like charges repel and unlike charges attract. ... The strong nuclear force is very short range and can only bind adjacent protons and neutrons. The electromagnetic force is long range.

Describe how fossil fuels are converted into usable energy<br> :)

mixer [17]

Answer:

Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.

Explanation:

Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.

petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.

Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.

gas and oil are used to heat homes.

The rate of diffusion of gas A is double the rate of gas B. The ratio of their molecular weight is

Dafna1 [17]

Answer:

Ratio is 4:1

Explanation:

from graham's law of gaseous diffusion:

${ \bf{ \frac{R _{A} }{R_{B} } = \sqrt{ \frac{M_{A} }{M_{B}} } }}$

but Ra = 2Rb:

${ \sf{ (\frac{2}{1} ) {}^{2} = \frac{M _{A}}{M _{B} } }} \\ \\ { \sf{\frac{M _{A}}{M _{B} } = \frac{4}{1} }} \\ \\ {M _{A}} : {M _{B} } = 4 :1$

3 Cu + 8HNO3 g 3 Cu(NO3)2 + 2 NO + 4 H2O

liubo4ka [24]

24.25 moles of NO can be produced using 97 moles of HNO3.

<h3>What is balanced chemical equation?</h3>

Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.

3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O

The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .

So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.

⇒ 8 HNO3⇔2 NO

⇒ 1 HNO3⇔ 1/4 NO

This means that for each mole of HNO3 produces 1/4 moles of NO.

So , for 97 moles of HNO3 , $\frac{1}{4} *97$ moles of NO can be made,

So, total moles of NO made are 24.25 moles.

The phrase “the danger is in the dose” is sometimes used when describing poisonous (toxic) chemicals. What does this mean?

Lostsunrise [7]

It means it depends on how much of the chemical you have. For ex. if 1 drop of snake venom might not kill you, but 20 drop could definitely kill you. Hope this helps!

Atoms of elements at the top of a group on the periodic table or smaller than the atoms of elements at the bottom of the group.

castortr0y [4]

Generally speaking the larger, more massive elements are less stable, like isotopes of elements. With this said, they are less likely to react since they will become heavy and unstable. This is why chlorine is more reactive with other elements like sodium than astatine.
