Burning fossil fuels in a low oxygen environment will most likely produceA) carbon monoxide.
B) hydrogen peroxide.
C) sulfuric acid.
D) methane.
Answers
Final answer:
Burning fossil fuels in a low oxygen environment most likely produces carbon monoxide due to incomplete combustion. This is because there isn't enough oxygen to react with carbon, leading to formation of carbon monoxide instead of carbon dioxide. The correct option is A.
Explanation:
When fossil fuels are burned in a low-oxygen environment, the most likely product will be carbon monoxide (A). This occurs because in a low-oxygen environment, there is not enough oxygen to react with the carbon atoms in the fossil fuels to form carbon dioxide, which is the normal product of combustion in a high-oxygen environment. Instead, each carbon atom reacts with only one oxygen atom, forming carbon monoxide instead of carbon dioxide. It's also important to note that the production of carbon monoxide in such situations is a significant health hazard as it is a poisonous gas.

The molarity of the HCl acid is 0.480 M. The correct option is 2.
What is molarity?
Molarity is the division of the mass of the solution to the volume of the solution.
The formula that is used is
Putting the values in the equation
0.620 * 12.7 = M1 * 16.4 = 0.480
Thus, the molarity of the HCl acid is 2). 0.480 M.

Molarity is equal to the moles of solute over liters of solvent. In getting the molarity of HCl, you must know the formula for two solutions which is equal to M1V1 = M2V2. (16.4 milliliters of HCl)M1 = (12.7 milliliters) (0.620 M KOH) and you have 0.480M HCl. The answer is number 2.
a gas that ignites a glowing splint is oxygen
Answers
The statement is true , oxygen is a gas which ignites a glowing splint.
How does oxygen ignite a glowing splint?
A splint is a simple piece which is used in scientific laboratories. They are typically long, thin strips of wood of about 6 inches long and 1/4 inches wide. They are consumable and inexpensive. They are used for lighting burners , chemical identification of various gases .
For gases which are hard to distinguish , a glowing splint test is used for identification of gases. . These tests are useful for identifying whether the gas is oxidizing,flammable or chemically inert.Oxygen is one of the gases which can be identified using the splinter test as it is combustible.
For the test, the splint is lit and is allowed to burn for a fraction of seconds and then blown out as the tip is still hot it is introduced into the jar containing the oxygen gas and thus re-igniting the splinter.

(1) decreases (2) increases (3) remains the same
Answers
Answer: (2) increases
Explanation: Entropy is the measure of randomness or disorder of a system. More is the random arrangement of molecules in a system , more is the entropy of the system. More ordered is the arrangement of molecules in a system, less is the entropy of the system.
When carbon dioxide sublimes, it means solid carbon dioxide is directly changing to gaseous state without undergoing into liquid state, thus the molecules will be more random and thus the entropy will increase.

Answer: Option (c) is the correct answer.
Explanation:
Moh's scale is used to detect the harness of a mineral. This scale displays harness of 10 minerals.
According to Moh's scale, the hardness of minerals given in the option are as follows:
- Topaz = 8
- Talc = 1
- Diamond = 10
Graphite is not included in Moh's scale.
Thus, we can conclude that the hardest known mineral is diamond.
