Intermolecular distance is the distance between the particles that make up matter. The graph below compares the intermolecular distances in two substances. One substance is gas and the other is a liquid. A bar graph is shown with the title Intermolecular Distance. The y axis title is Distance. The x axis title is Substance. There are two bars on the x axis. One is labeled X and the other is labeled Y. The bar for X is higher than the bar for Y. Which statement best describes the two substances?

Answers

Explanation:

In gases, the molecules are held together by weak Vander waal forces. Due to this they have more kinetic energy and hence, more number of collisions take place between the molecules of a gas.

Therefore, they tend to diffuse at a faster rate and distance traveled by them is more as compared to the distance traveled by the molecules of a liquid.

On the other hand in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases but not strong enough as they are in solids. Due to this molecules of a liquid are able to slide past each other. Hence, they have medium kinetic energy.

Therefore, less number of collisions take place between molecules of a liquid as compared to gases.

Thus, we can conclude that particles collide in gas so, substance X is a gas.

X is the gas and Y is the liquid. Intermolecular distances are farther apart in gases than in liquids.

Suppose the filament in a super-powerful flashlight is heated up to 3600 K. What type of light would be given off by this filament, mostly?

Answers

Answer:

The correct answer is "Infrared light".

Explanation:

Infrared light, also known as infrared radiation, is a type of light that can no be seen but it can be felt from the heat that it generates. The spectrum of wavelengths that comprise the infrared light is given from 700 nanometers, which is the edge of visible red light, up to 1 millimeter of wavelength. Near-Infrared light is the one that can reach the highest temperature, reaching from 3000 to 5200 K. Therefore, a super-powerful flashlight heated up to 3600 K can be given off infrared light.

If the total mass of the products of a reaction is 250 g, what was the total mass of the reactants

Answers

The total mass in a reaction is always conserved . Thus the total mass of reactants will be equal to the total mass of products. Hence f the total mass of the products of a reaction is 250 g, the total mass of the reactants is also 250g.

What is law of conservation of mass ?

Mass conservation law is same as that of law of conservation of energy. That is, mass can neither be created nor be destroyed. Therefore, total mass of the system is conserved or it is a constant.

For any type of changes occurring for a substance, let it be a chemical change or physical change the total mass of the initial or original substance is gaines after the change from the new product or new state of the same substance.

Thus, no atoms created or lost in a reaction but they are regrouped to form new products. The new products are formed by bond making or bond breaking in the reactants their weight is completely transferred to the products.

Therefore, if a reaction is having total mass of 250 g in product side then it 250 g was the total mass in reactant side.

Every chemical equation must be balanced to preform the conservation of mass law, so, what ever is on the products is going to be on the reactants. The mass is not created nor destroyed.

Answer: 250 g
