which Two of the following are pure substances*
A. Compounds
B. Elements
C. Solutions
D. Mixtures
Answer:
I think A and B
Explanation:
Answer:
A. & B.
Explanation:
Neither can be broken down into something besides an atom, the "purest" form matter can exist in. For example, if you were to break down C6H12O6 (glucose), you wouldn't be able to break down a singular atom of carbon into something different.

Imagine that one tree outside your home looks unhealthy, although all the other trees seem healthy and strong. Describe how you could apply scientific thinking to the situation to determine why only one tree looks unhealthy. Write your answer down bellow Did you: include an asking question based on your observation about trees? Include details about what kind of data you would collect answer you question? Include a plan about how you would use the data collected to answer you question? Order the steps of your scientific investigation in a logical in order Question from Calvert Learning
Answer:
Hypothesis---experiments----results----conclusion.
Explanation:
First we make a hypothesis means a statement about why the tree looks unhealthy. In this segment of scientific method we have to test the hypothesis through experimentation. After that we have to take the readings of various parts of the tree and analyze the data to find out the problem. In the next step, we have to made the results on the basis of the data that is obtained. In the last we have to write the conclusion of the analysis and see the hypothesis.
How do submarine volcanoes affect autotrophic bacteria?
Answer:A large number of autotrophic bacteria—bacteria that produce their own food—live near hydrothermal vents and submarine volcanoes.
These bacteria are considered chemosynthetic, meaning they produce food from chemical reactions usually involving carbon dioxide, oxygen, or hydrogen

What happens during the treatment step in refining crude oil for energy use?
A. Chemicals are added to the oil so that it burns more cleanly.
B. Different fractions are combined to make a variety of final products.
C. Heavy fractions are chemically “cracked" into lighter ones.
D. Crude oil is cleaned with a water mixture.
Answer:
I think its B im not sure lol but I would wait for someone that actually would know for sure
Different fractions are combined to make a variety of final products during the treatment step in refining crude oil for energy use. Therefore, the correct option is option B.
What is refining?A material or a form is purified by the process of refining, which is also maybe referred to by the mathematical word affixing. The phrase is typically used to describe a resource that is practically useable but is more valuable in its purest form.
The phrase refers to a wide range of changes, including more extreme ones as the conversion of ore to metal (for more information, see Refining (metallurgy)). Different fractions are combined to make a variety of final products during the treatment step in refining crude oil for energy use.
Therefore, the correct option is option B.

give two areas where the compressible nature of gas is applied
Answer:
1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.
2. Balloons can be easily filled with air.
The fact that a gas is easily compressible is applied in the colling devices such as air conditioners as well as in the pumping of tyres with air.
Are gases compressible?Gases are easily compressible because they do not have a definite volume. This is positively applied in many areas of life.

Now imagine that you're waiting for your soup to cool down, and you leave it on the counter while you go do your homework. Your homework is so interesting that you forget all about your soup, and now it's cold! Actually, if you were to measure the temperature, you'd find that your soup is the same temperature as the air in the room. What's going on?
Explanation:
Generally, heat flows from a hot environment to a cold (lesser temperature) environment. In this case, the soup is the hot environment and the air is the cold temperature.
Heat would continue to flow from one environment to another until thermal equilibrium is reached. At this thermal equilibrium, both environments would have the same temperature.
What coefficient should go in front of the hydrogen peroxide (H2O2 ) molecule to make the chemical equation balanced? ___ H2O2 ➞ 2 H2O + O2
Answer:
2
Explanation:
H2O2 ➞ 2 H2O + O2
The reaction is currently not balanced because the number of atoms on the reactant side is not equal to that of the product side
Hydrogen
Reactant = 2 Product = 4
Oxygen
Reactant = 2 Product = 4
Adding 2 to H2O2 balances the reaction as the number of atoms of both elements are now balanced on both sides of the equation
2H2O2 ➞ 2 H2O + O2

Explanation:
Does potassium or lithium have the smaller atomic radius? Support your answer using atomic structure (ex: energy levels, nuclear charge, attraction).
Answer:
Atomic radii increase in size as you progress down the columns of the periodic table. This is because as you add more electrons, and fill more electron shells, the total radius across the atom increases.
Answer:
lithium because it atomic number is 3
