An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. What other characteristic does the radiation have?some shielding required
no mass
large mass
high penetrating power

Answers

Answer 1

Answer: The radiation emitted is a beta particle with a -1 charge. Beta particles have a medium penetrating power. An emission of beta particles requires shielding because of the hazards it pose to humans. Thus, one characteristic of this radiation is that some shielding is required.

Answer 2

Answer:

Another characteristic that this type of radiation have is that: A. some shielding required.

The types of radiation.

In Science, there are four (4) major types of radiation and these include the following:

Neutron

Alpha

Beta

Gamma

A beta particle is an isotope which undergoes radioactive decay by emitting a radiation with a -1 charge. Also, it requires some form of shielding because of the hazards it pose to living organisms.

The molar heat of vaporization of water is 40.7kj/mol. How much heat must be absorbed to convert 50.0 grams of liquid water at 100°C to steam at 100°C?

Answers

You have to use the formula q=nΔH(vap)
q=the heat absorbed or released
n=the number of moles of the sample (in this case 2.78mol (50g/18g/mol))
ΔH(vap)=the heat of vaporization for the sample (in this case 40.7kJ/mol)

When you plug everything in you should find that 113.05kJ is needed to vaporize 50g of water. (the temperature does not change during a phase change since all of the heat absorbed is being used to break the intermolecular forces and none of it is being used to speed up the molecules).

Observe the nature changing around your home. You can observe plants, animals, and parts of your actual home as you begin to notice changes in matter. Collect data for two examples of changes in matter. Use the Changes in Matter observation questions to determine if your examples are physical or chemical changes.Your answer should include two examples, the types of changes observed, and evidence of how the examples were formed. You can use this format:

Example 1:

Type of Change:

Evidence:

Answers

Answer:

Example 1. One change I observed was when cooking, I needed to boil water. The water was later evaporated due to the increase of heat from the stove below the pot. Heat traveled and transferred from the stove to the pot then the water. This change is from liquid to gas.

Example 2. I was mixing sugar into my tea, the sugar dissolved into the tea. This is an example of dissolving a solid into a liquid. The tea took the properties of the sugar and turned the drink sweet.

Extra, taking a hot shower and steam leaves the shower. This change is of evaporation.
