answer asap please!!!!!!!!!!!!!!!!!!!!!

Answer:

Carbon Dioxide: CO2

Water: H2O

Oxygen: O2

Answer:

Option B

Explanation:

Remember that the products are on the right side of a chemical equation while the reactant is on the left.

In this case we have...

C2H6 + O2 ⇒ CO2 + H2O

Since C2H6 and O2 are on the left side that would mean they're the reactants, while CO2 + H2O are the products. Which means your answer is option B or "C2H6 + O2 are the reactants, CO2 + H2O are the products."

Hope this helps.

Answer:

1.18 moles of gas

Explanation:

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container until the pressure is 0.78 atm, how many moles of gas remain in the container?​

for the sealed rigid container, the pressure is directly proportional to the amount of gas

3.00moles/1.98  atm =  ? moles/0.78 atm

? = 3.00 X 0.78/1.98  =1.18 moles of gas

Answer:

A. Turn the volume up for more energy.

Explanation:

The reason why this is the correct answer is because the louder the music gets the more energy it puts out therefore the answer is option A.

The students increase the amplitude of the sound waves of the music turn the volume up to create more energy. Hence option A is correct.

Energy is defined as a quantitative quality that is conveyed to a person or a physical system and is discernible in the way work is done as well as in the way heat and light are produced. A conserved quantity is energy. According to the law of conservation of energy, energy can change its form but cannot be created or destroyed.

Sound waves are defined as the pattern of disruption brought on by energy's passage through a medium when sound travels away from its source. Pressure waves are produced by the vibration of objects and are known as sound waves. A sound source, such as the vibrating speaker's diaphragm in a stereo, produces the sound waves.

Thus, the students increase the amplitude of the sound waves of the music turn the volume up to create more energy. Hence option A is correct.

Answer:

6. 66.674

Explanation:

You are given moles of H20 and the question is asking you to find the mass. You take the amount of moles given, 3.70 mol H2O and multiply it by the molar mass of water to go from moles to grams. The molar mass is the mass of 1 mole of that atom. So 1 mole of H2O is 18.02 g.

3.70 moles H2O x 18.02g = 66.674 g

Answer:

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. As per Einstein's light quantum theory, photons have energy equal to their oscillation frequency times Planck's constant.

Explanation:

A photon is defined as the the smallest discrete amount or quantum of electromagnetic radiation. It can also be called as energy packets.

Photon  is considered to be the basic unit of all light. As per Einstein's  quantum theory, photons have energy equal to their oscillation frequency times Planck's constant.

The energy of photon equal to the  difference in energy between the atom's excited state and its final state.

The photon energy of the emitted photon is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each transition has a specific energy difference.

When an atom in an excited state emits a photon of radiation, the energy of the photon is equal to the  difference in energy between the atom's excited state and its final state.

Concentration of NaOH will you place into the leaf jar to absorb the carbon dioxide at 0.75 M concentration.

Concentration is calculated by dividing a constituent's abundance by the mixture's total volume. Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.

The amount of solute that has dissolved in a specific amount of solvent or solution is measured as solution concentration. A concentrated solution is one that has a significant amount of dissolved solute in it. A diluted solution is one that has a little amount of dissolved solute in it.

Concentration is the ratio of the volume of the solution ( V ) to the mass of the solute ( m ) that is dissolved in it. C = m / V. Molality, mole fraction, and molarity are the three methods for calculating the concentration of a solution.

Molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion are examples of quantitative units of concentration.

Thus, option C is correct.
