What occurs when a molecule combines with Oxygen and produces heat?
A. It dissolves
B. It precipitates
C. It Evaporates
D. it combusts
Answer:
D. it combustsExplanation:
Combustion is when fuel reacts with oxygen to release heat energy. Combustion can be slow or fast depending on the amount of oxygen available. Combustion that results in a flame is very fast and is called burning. Combustion can only occur between gases.
What is the molar mass of a compound compared to an element?
Answer: The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).
Explanation: The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
Describe a Mesosaurus.
Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 3.3 feet long. The skull and tail were both long and narrow, and the animal probably undulated through the water as it fed on small crustaceans and other prey with its jaws, which were full of long, thin, pointed teeth.

In the reaction 2Na3N-6Na+N, how many moles of Na are produced when 6 mol of Na3N
decompose?
moles of Na produced = 6 moles
Further explanationGiven
Reaction
2Na3N---> 6Na+N
6 moles of Na3N
Required
moles of Na
Solution
I don't really understand the reaction in the problem, all I know is the decomposition reaction of sodium azide NaN3
2NaN₃ → 2Na + 3N₂
The reaction coefficient shows the mole ratio of the compounds involved in the reaction
From the equation(balanced), mol ratio of Na : NaN₃ = 2 : 2, so mol Na :
= 2/2 x moles NaN₃
= 2/2 x 6 moles
= 6 moles
For the balanced equation 2C6H6OS+1102=12CO+6H2O+2SO3 how many moles of C6H6OS reacted if 0.474 moles of SO3 are produced?
Answer:
0.474 moles of C₆H₆OS
Explanation:
Step 1: Write the balanced equation
2 C₆H₆OS + 11 O₂ ⇒ 12 CO + 6 H₂O + 2 SO₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of C₆H₆OS to SO₃ is 2:2.
Step 3: Calculate the moles of C₆H₆OS reacted if 0.474 moles of SO₃ are produced
We will use the previously established molar ratio.
0.474 mol SO₃ × 2 mol C₆H₆OS/2 mol SO₃ = 0.474 mol C₆H₆OS

How many grams of water could be made from 5.0 mol H2 with excess O2? 2 H2 + O2 --> 2 H2O
Answer:
Explanation:
5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.
The mass percent of hydrogen in CH₄O is 12.5%.
What is the mass percent?Mass percent is the mass of the element divided by the mass of the compound or solute.
Step 1: Calculate the mass of the compound.
mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu
Step 2: Calculate the mass of hydrogen in the compound.
mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu
Step 3: Calculate the mass percent of hydrogen in the compound.
%H = (mH in mCH₄O / mCH₄O) × 100%
%H = 4.00 amu / 32.01 amu × 100% = 12.5%
The mass percent of hydrogen in CH₄O is 12.5%.
CO2 = 1.580 grams H2O = 0.592 grams Lookup the molar mass of each element in the compound Carbon = 12.0107 Hydrogen = 1.00794 Oxygen = 15.999 Calculate the molar mass of CH4O by adding the total masses of each element used. 12.0107 + 4 * 1.00794 + 15.999 = 32.04146 Now calculate how many moles of CH4O you have by dividing by the molar mass. m = 1.15 g / 32.04146 g/mole = 0.035891 mole Now figure out how many moles of carbon and hydrogen you have. Carbon = 0.035891 moles Hydrogen = 0.035891 moles *

Consider a car being acted on by balanced forces. Can you conclude whether the car is moving or at rest? Explain your response.
Since the car is being acted upon by balanced forces, the car is at rest. as the forces are being balanced.
What is a force?
Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

would you consider alcohol as food nutrient? explain.
Answer:
Explanation:
No I would consider it a drug
Alcohol is considered a drug and doesn't fall under the category of food nutrients.
What is alcohol?Alcohol is a drink that contains ethanol. It is a type of alcohol that acts as a drug and is formed by the fermentation of fruits, grains, or sources of sugar.
Alcohol is classified as a depressant which means it slows down vital functions resulting in unsteady movement, slurred speech, and an inability to react quickly.
Alcohol overdose creates even more painful, depressant effects such as toxicity where the body vomits the poison, and finally unconsciousness, coma, or death. These reactions depend upon the quantity of consumption of alcohol and how quickly.
Alcohol is a drug that damages a person’s ability to think rationally and distorts his judgment. Alcohol affects the mind, so it can never be considered nutritious food.

How many moles are there in 100 grams of carbon dioxide?
Answer:
there are 8.3259093974539 moles in 100 grams of carbon dioxide
The number of moles that are in 100 grams of carbon dioxide is 2.272 g/mol. Moles can be calculated by dividing the mass by the molar mass of the compound.
What are moles?"The mole is a SI unit of measurement that is used to calculate the quantity of any substance."
The molar mass of many compounds can be calculated by dividing the mass of the compound by the number of moles of the compound. Mass is the quantity of matter of a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.
Moles = mass / molar mass
The mass of carbon dioxide is 100 grams
The molar mass of carbon dioxide is 44.01 g/mol
Put the values in the formula of moles:
100 / 44.01 = 2.272 g/mol
Therefore, there are 2.272 g/mol of moles in 100 grams of carbon dioxide.
