Explanation:

Answer:

Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth.

Answer:

[tex]\boxed {\boxed {\sf v \approx 0.22 \ cm^3}}[/tex]

Explanation:

We are asked to find the volume of a substance.

We are given the density and the mass. The density of a substance is its mass per unit volume. The formula for calculating density is:

[tex]\rho= \frac{m}{v}[/tex]

We know the density of the substance is 13.6 grams per cubic centimeter and the mass is 3.0 grams.

Substitute these values into the formula.

[tex]13.6 \ g/cm^3= \frac{3.0 \ g }{v}[/tex]

We are solving for the volume, so we must isolate the variable v. First, cross multiply. Multiply the first numerator by the second denominator, then multiply the first denominator by the second numerator.

[tex]\frac{13.6 \ g/cm^3}{1}= \frac{3.0 \ g }{v}[/tex]

[tex]13.6 \ g/cm^3 *v =3.0 \ g *1[/tex]

Multiply on the right side of the equation.

[tex]13.6 \ g/cm^3 *v =3.0 \ g[/tex]

The variable is being multiplied by 13.6 grams per cubic centimeters. The inverse operation of multiplication is division, so we divide both sides of the equation by 13.6 g/cm².

[tex]\frac {13.6 \ g/cm^3 *v}{13.6 \ g/cm^3} =\frac{3.0 \ g }{13.6 \ g/cm^3}[/tex]

[tex]v =\frac{3.0 \ g }{13.6 \ g/cm^3}[/tex]

The units of grams cancel.

[tex]v =\frac{3.0 }{13.6 \ cm^3}[/tex]

[tex]v= 0.2205882353 \ cm^3[/tex]

The original measurement of density has 3 significant figures and the measurement of mass has 2. Our answer must have the least number of sig figs, which is 2. For the number we found, that is the hundredth place. The 0 in the thousandth place tells us to leave the 2 in the hundredth place.

[tex]v \approx 0.22 \ cm^3[/tex]

The volume of the substance is approximately 0.22 cubic centimeters.

Chemical transformation of a carbon-carbon double bond is the addition reaction.

Explanation:

Consequently, if the bond energies of the product molecules are greater than the bond energies of the reactants, the reaction will be exothermic.

Answer:

British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.

Answer:

three stable isotopes

Neon has three stable isotopes: 20Ne (90.48%), 21Ne (0.27%) and 22Ne (9.25%). Ne and 22Ne are partly primordial and partly nucleogenic (i.e. made by nuclear reactions of other nuclides with neutrons or other particles in the environment) and their variations in natural abundance are well understood.

The statement that is true is the charge of all isotopes are same. The correct option is D.

Isotopes are members of an element family that have the same number of protons but differ in terms of neutrons.

The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus.

There are three isotopes of neon. Since there is no significant global production of these isotopes, the more plentiful 20Ne and 22Ne are essentially all primordial.

Isotopes can form naturally through radioactive decay of a nucleus or unnaturally by bombarding a stable nucleus with charged particles in a nuclear reactor using accelerators or neutrons.

Thus, the correct option is D as they all have same charge.

1.6 grams of oxygen will react with 2.4 grams of magnesium.

Explanation:

Given:

2.4 grams of magnesium.

The reaction between magnesium and oxygen:

[tex]2Mg+O_2\rightarrow 2MgO[/tex]

To find:

The mass of oxygen required to react with 2.4 grams of magnesium.

Solution:

The mass of magnesium = 2.4 g

Moles of magnesium =[tex]\frac{2.4 g}{24.305 g/mol}=0.0987 mol[/tex]

[tex]2Mg+O_2\rightarrow 2MgO[/tex]

According to the reaction, 2 moles of magnesium reacts with 1 mole of oxygen, then 0.0987 moles of magnesium will react with:

[tex]=\frac{1}{2}\times 0.0987 mol=0.04935\text{mol }O_2[/tex]

Moles of oxygen required = 0.04935 mol

The mass of 0.04935 moles of oxygen :

[tex]=0.04935\times 31.999 g/mol=1.579 g\approx 1.6 g[/tex]

1.6 grams of oxygen will react with 2.4 grams of magnesium.
