Answer:

The reaction rate would decrease

Explanation:

What would happen to the rate of the forward reaction if the concentration of nitrogen were decreased? The reaction rate would decrease . What will happen to the rates of the forward and reverse reactions when a catalyst is added? Both forward and reverse rates increase.

Answer:

Nuclear fusion, Conduction, Conduction, Radiation.

The Sun produces energy deep inside its core by fusing hydrogen atoms together to form heavier ones through nuclear fusion. Conduction and convection are used to move heat from the core to the surface.

Radiation is the electromagnetic transmission of heat energy through space. The majority of the electromagnetic radiation that the sun emits and that reaches the Earth is invisible. Only a tiny fraction is visible light. Light consists of waves of various frequencies.

When two objects with different surface temperatures come in contact with one another, conduction happens. Up until they reach the same temperature, heat moves from the warmer to the cooler object. Heat moves through a substance by conduction when molecules collide.

Thus the correct order is Nuclear fusion, Conduction, Conduction, and Radiation.

If a mixture is prepared by mixing 29.27 mL of the blue dye solution with 35.00 mL of the red dye solution and 14.73 mL of the yellow dye solution, the molar concentration of the blue dye in the mixture is

MB'=0.1189M

Generally, the equation for the moles  is mathematically given as

Moles=Molarity *volume

Therefore

For Blue dye

MB=0.3523*25.27*1/1000ml

MB=8.90*10^{-3}

For red dye

MR=0.1017*35.27*1/1000ml

MR=3.55*10^{-3}

For yellow dye

MY=0.3523*14.73*1/1000ml

MY=2.27*10^{-3}

Where

Total volume is

T=25.27+35.ml+14.73

T=75ml

In conclusion, The molar conc of blue dye is

[tex]MB'=\frac{8.90*10^{-3}*1000}{75}[/tex]

MB'=0.1189M

Answer:

0.0499 moles

Explanation:

56.08g => 1 mol

2.80g => y mol

Y = 2.80/56.08 = 0.0499 moles

A sample of calcium oxide (CaO) has a mass of 2.80 g. the molar mass of CaO is 56.08 g/mol. No. of moles of CaO this sample contain are 0.499.

Avogadro's number is the number of units in one mole of any substance and equals to 6.02214076 × 10²³. The units can be electrons, atoms, ions, or molecules.

No. of moles is defined as a particular no. of particles that we can calculate with the help of Avogadro’s number.

Mass of a particular product is also find out by stoichiometry of a reaction as per the no. of mole given in the reaction.

No. of moles = Mass of compound ÷ Molar mass of compound

No. of moles = 2.80 ÷ 56.08 = 0.0499

Therefore, A sample of calcium oxide (CaO) has a mass of 2.80 g. the molar mass of CaO is 56.08 g/mol. No. of moles of CaO this sample contain are 0.499.

Answer:

Electrons

Explanation:

"Static charges" occur when the number of positive charge and negative charge are not equal. This can be applied to neutral objects by friction, induction and conduction with the help of "electrons."

In friction, the electrons are being transferred between the objects being rubbed together.

In conduction, the electrons are also being transferred from one object to another but not through rubbing; instead through direct contact.

In induction, the electrons are able to react immediately without the need for direct contact.

So, electrons are being utilized in these processes in order to create charge.

It occurs when two waves meet while traveling along the same medium.

Answer:

When it is cold, it's hard for the molecules and whatever microscopic organisms live there to move around.

When it is hot, the molecules will move quicker due to a chemical reaction with the atoms and other forms of energy increasing with the heat energy. This reaction happens because 2 forms of energy meet.
