Answer:
            The name of given molecule is 3-Methylpent-2-ene.

Explanation:
                   First of all a carbon chain of five carbons was drawn. Then a double bond was made between carbon 3 and 4 (starting from left). A methyl group was drawn at middle carbon which is at position 3.

                    Molecule sketched was named as,

1) A longest chain containing double bond was selected and numbering was started from the end closest to double bond. Hence, 

                                  2-Pentene or Pent-2-ene

2) The position of substituent was specified before the parent name, Hence,

                       3-Methyl-2-Pentene or 3-Methylpent-2-ene

If a cube has a mass of 90.91 kilograms and a weight of 200 pounds on Earth, what will its mass and weight be on another planet?
Fudgin [204]

Answer:

The mass will be 90.91 kilograms, we can’t figure out the weight without knowing how much gravity is on the other planet.

Explanation:

Mass is the amount of substance a matter contains. The more the substance a matter contains, the more massive it becomes. The mass of an object is the same everywhere in the universe. Therefore, the cube will have the same mass of 90.91Kg in another planet.

Weight is a function of mass and the force of gravity on such a body. The weight of a body relies on the prevailing acceleration due to gravity in a particular place. Some places have gravity higher than that on earth and so they will have more weight. This is why we can't figure out weight without knowing the gravity in the other planet.

A certain chemical reaction releases 36.2 kJ/g of heat for each gram of reactant consumed. How can you calculate what mass of re
Lilit [14]

Answer:

0.038 g of reactant

Explanation:

Data given:

Heat release for each gram of reactant consumption = 36.2 kJ/g

mass of reactant that release 1360 J of heat = ?

Solution:

As  36.2 kJ of heat release per gram of reactant consumption so first we will convert KJ to J

As we know

1 KJ = 1000 J

So

36.2 kJ = 36.2 x 1000 = 36200 J

So it means that in chemical reaction 36200 J of heat release for each gram of reactant consumed so how much mass of reactant will be consumed if 1360 J heat will release

Apply unity formula

                 36200 J of heat release ≅ 1 gram of reactant

                 1360 J of heat release ≅ X gram of reactant

Do cross multiplication

              X gram of reactant = 1 g x 1360 J / 36200 J

              X gram of reactant = 0.038 g

So 0.038 g of reactant will produce 1360 J of heat.

Calculate the mass percent of calcium chloride in 8.87 g of calcium chloride in 65.1 g of water
zhannawk [14.2K]

Answer:

11.99 % ≅ 12.0%.

Explanation:

∵ mass % = [mass of solute/mass of solution] x 100.

mass of solute (CaCl₂) = 8.87 g & mass of solution = 8.87 g + 65.1 g = 73.97 g.

<em>∴ mass % of (CaCl₂) = [mass of solute/mass of solution] x 100 </em>= ( 8.87 g/ 73.97 g) x 100 = <em>11.99 % ≅ 12.0%.</em>

How many molecules of Ca are found in a sample with 0.2 mols?
DochEvi [55]

Answer:

\boxed{1.2 \times 10^{23}\text{ atoms}}

Explanation:

6.023 × 10²³ atoms of Ca are in 1 mol of Ca

\text{No. of atoms} = \text{0.2 mol} \times \dfrac{6.023 \times 10^{23}\text{atoms }}{\text{1 mol }} = \mathbf{1.2 \times 10^{23}} \textbf{ atoms}}\\\\\text{There are }\boxed{\mathbf{1.2 \times 10^{23}} \textbf{ atoms}} \text{ atoms in 0.20 mol of Ca}

The diagram shows Niels Bohr’s model of an atom.
PtichkaEL [24]

Answer:

Energy is absorbed, and an emission line is produced.

Explanation:

Electrons are present and revolving continuously in the orbits that are present around the nucleus. The energy of electron are fixed and unable to move to other orbits due to the strong attractive force of the proton which is present in the nucleus of the atom. If the electron wants to jump from the first energy level to the second energy level, so the electron has to absorb enough energy which can overcome the attractive force of proton.
