do all types of energy have the same amount of energy
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.

What is the volume of a substance that has a density of 13.6 g/cm and a mass of 3.0 g?
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.
ρ= 13.6 g/cm³m= 3.0 gSubstitute 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.

Explanation:
There are three stable forms of neon: neon-20, neon-21, and neon-22. Which statement is true?
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.
What are isotopes?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.

Your question seems incomplete, the missing options are:
- the atomic mass of the three isotopes is the same
-the three isotopes are all radioactive
-the three isotopes are equally abundant in nature
-the charge of all isotopes is the same

If I have 2.4g of magnesium, how many g of oxygen(O2 ) will I need to react completely with the magnesium? 2Mg +O2 → MgO
Explanation:
just trying....hope that helps
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.
