Sodium Chloride (NaCl) can be classified as a salt
Explanation:
Sodium chloride is an "ionic compound" is known as salt. The ratio in which the sodium(Na) and chloride(Cl) present in sodium chloride in NaCl is 1:1. It is found in seawater and is accountable for the salinity of the seawater. Also, NaCl is the extracellular fluid for various multicellular organisms.
When refined, it becomes in its 'edible' form and is used in food preservatives. Whereas, the large quantity of sodium chloride is used in various industries.
B) the hypothesis is tested extensively and competing hypothesis are eliminated
C) there are no other competing hypothesis
D) the hypothesis can be tested at least once
2) A preliminary untested explanation that tries to explain how or why things happen in the manner observed is a scientific ________.
A) law
B) theory
C) fact
D) hypothesis
Gay-Lussac’s law
Avogadro’s law
Charles’s law
correct answer is gay lussacs law
Answer:
Gay-Lussac’s law
Explanation:
Gay's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
Answer:
Clouds generally form within the troposphere.
Explanation:
A cloud is a mass of water droplets, ice crystals or both at the same time, which remains in suspension in the atmosphere, and whose formation is due to the condensation of water vapor in the sky.
Clouds form when the air is saturated and can no longer contain water vapor, this can happen in two ways:
1. The amount of water in the air has increased.
2. The air cools to its dew point.
Clouds generally form within the troposphere.

The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.
Explanation:
The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.
It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.
The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.
The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.
For example the structural formula for Methane (CH4)
This problem can be solved using the Combined Gas Law. The formula for it is
Let's go ahead and plug in the known values. Since pressure remains the same, it does not matter what value we plug in, so let's assume 1 atm for both sides.
Now, we just need to solve for the unknown. Start by simplifying the left side and right numerator.
0.001 =
Multiply both sides by x.
0.001x = 0.140
Divide both sides by 0.001.
x = 140 K
Convert that to Celsius (K = C + 273)
140 = C + 273
C = -133
So, the volume of your gas will be 0.140 L at -133° C.
