Which of the following will form a solution? (Select all that apply.)
string and water
sand and water
sugar and water
salt and water
Answers
Answer:
Sugar and Water
Salt and Water
Explanation:
If you mix sand (or string) with water, it is a mixture, but it is not a solution. The sand (and string) cannot dissolve into the water.
So, when “Sugar” is added to water, the sugar “dissolves” into the water creating a “sugar water” solution. Salt and water also mixes to become a solution.
(If you want to see your for yourself, put a cup of water in the microwave and heat it up, then take it out (be careful when taking it out). Put a little bit of salt (or sugar) into the cup and it will eventually dissolve in the water)
Just think of it like powdered lemonade, but instead of it turning yellow it's clear. But it will still taste good (if you use sugar, because that's essentially what lemonade is)
Because those two can mix the others can’t mix

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.

An example of chemical weathering are;
Sandstone experiences heat and pressure and becomes quartzite. Calcium carbonate dissolves.What is Chemical Weathering ?Chemical Weathering can be described as the type of weathering that do take place due to the breaking down of the rock particles into smaller pieces which is usually as a result of chemical process.
It should be noted that when the process is taking place it scould be due to the Extreme heat and pressure which can affect the composition of the particles and as a result of this there could be formation of products from the break down.

Sandstone experiences heat and pressure and becomes quartzite
Calcium carbonate dissolves
These are both examples of chemical weathering because the composition of these things changed. When shale is worn into small pieces, it is still shale, and rocks breaking into pieces as they tumble down a mountain are both examples of physical weathering because the weathering is not changing the composition of the rock.

c) What type of bond would form between these two atoms? (2pts)
d) What would the compound formed between these atoms be named? (4pts)
e) What would the formula be? (4pts)
Answers
Answer:
d
Explanation:
a) Atom 1 has 35 protons and 45 neutrons, which means it is the element bromine (Br). Atom 2 has 12 protons and 12 neutrons, which means it is the element magnesium (Mg).
What is a metalloid?A metalloid is an element that acquires both metal and nonmetal properties. Metalloids have some characteristics of metals, such as being good conductors of electricity, while also having some nonmetallic properties such as being brittle and lacking the ability to be hammered into shape. They are located along the "staircase" on the periodic table, between the metals and nonmetals, and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids are important in various applications such as semiconductor industry, in which silicon is the most widely used metalloid for the production of computer chips and solar cells.
b) Bromine (Br) is a nonmetal and magnesium (Mg) is a metal.
c) Magnesium (Mg) is a metal and bromine (Br) is a nonmetal, so they would form an ionic bond.
d) The compound formed between magnesium (Mg) and bromine (Br) would be named magnesium bromide.
e) The formula for magnesium bromide is MgBr2, since magnesium (Mg) has a +2 charge and bromine (Br) has a -1 charge.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
