Answer:

This is because their is a repulsive force between the magnetic north and the geographical north since the rod experiences the Earth's magnetic field.

The iron rod deflects at an angle (angle of dip) from the horizontal.

Answer: Answer in explanation

Explanation:

If you're talking about *stars* in general, as mass increases, so does the luminosity - it burns brighter and faster.  A *star* will not increase it's mass generally, unless something falls into it;  and generally - even if a *planet* falls into a star (take our sun, for example - you could plunge the Earth into the sun, and you've only increased the sun's mass by 1/1,300,000th... )  

As radius increases, for example, when our sun slips into the Red Giant phase, it will become redder, but the surface will have increased 100,000 times - so, the amount of light it puts out now from a square meter, compared to how much it will put out when it's a red giant will be reduced 20 fold;  however, there's so much ***more*** area, that the overall brightness of our sun will increase dramatically.

Answer:

During the process of electrolysis, ions that are formed will get discharged to reform neutral atoms at the state of electrons, whereas the preferential meaning which in case one or more kind of cations and anions in the electrolyte, the one with the higher concentration or at a lower position activity will get discharged first.

Answer:

c = 5505263.16 J/g.°C

Explanation:

Given data:

Mass of ring = 12 mg (12/1000 = 0.012 g)

Calories used = 30.0 cal (30.0 ×4184 = 125520 J)

Temperature increases = 1.9°C

Specific heat of ring = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

125520 J = 0.012 g×c ×1.9°C

125520 J = 0.0228 g.°C ×c

c = 125520 J /  0.0228 g.°C

c = 5505263.16 J/g.°C

Function

Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.

Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.

Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.

Purpose

The purpose of genes is to store information.

Each gene contains the information required to build specific proteins needed in an organism.

Answer:

Kr- dispersion forces

CBr4- dispersion forces

CH3OH - dispersion forces, dipole interaction, hydrogen bonding

NaF- ionic

Kr-<CBr4<CH3OH<NaF

Explanation:

The magnitude of intermolecular forces influences the boiling points of substances. The stronger the intermolecular forces the higher the boiling point.

The strongest intermolecular forces here is the Ionic bond hence it accounts for the highest boiling point followed by CH3OH having hydrogen bonding.

Though Krypton and CBr4 both have dipole interaction, the higher relative molecular mass of CBr4 makes it to have a higher boiling point than Kr

Explanation:

The excess reactant is the reactant left over after a chemical reaction. It is found when the limiting reactant is completely done. The answer to your question is option B. The excess reactant is what is found after the reaction is complete. Our answer is Option B.

Answer:B

Explanation: Excess Reactant - The reactant in a chemical reaction that remains when a reaction stops when the limiting reactant is completely consumed consumed. The excess reactant remains because there is nothing with which it can react.

It's the distance covered by light in one year.

Answer:

Use dilution equation:  

M1V1 = M2V2  

1.0*V1 = 2.4*500  

V1 = 1200mL  

You already have 500mL KCl solution . You must add: 1200mL - 500mL = 700mL water.

Answer:

Separate the reaction into half equations

Explanation:

When we want to balance redox equations, we must take cognizance of the fact that a specie was oxidized and another specie was reduced.

Hence we must identify the specie that was oxidized and the one that was reduced and then break up the whole redox reaction into oxidation and reduction half equations.
