Answer:

The name of the molecule which is given below is 2-pentene.

Explanation:

Alkenes are the organic compounds which are composed of carbon and hydrogen atoms, in which double bond is present.

In the given diagram:

Each corner and joints shows the carbon atoms and number of carbon atoms in it is 5.

One double bond is present in the 2nd position.

So the compound is 2 pentene.

Hence, 2 pentene is the name of the compound.

Describe the ways in which ionic compound nomenclature differs from covalent compound nomenclature

Igoryamba

Answer:

Ionic compound are when electrons are given to another element, making one atom positive and the other negative, so they attract. Covalent compound is when both atoms share electrons with each other.

Which statement explains the energy term in this reaction

lana66690 [7]

Answer:

Mass is lost due to the conversion of mass to energy

Explanation:

The question is not complete, the complete question is given as:

$^{235}_{72}U +^{1}_{0}n$ ⇒ $^{140}_{56}Ba+^{93}_{36}Kr+3^{1}_{0}n+energy$

total mass equals 236.053 u total mass equals 235.868 u

Which statement explains the energy term in this reaction? (1) Mass is gained due to the conversion of mass to energy. (2) Mass is gained due to the conversion of energy to mass. (3) Mass is lost due to the conversion of mass to energy. (4) Mass is lost due to the conversion of energy to mass.

Answer: From Einstein’s equation E = mc², when a radioisotope element undergoes fission or fusion in a nuclear reaction, it loses a tiny amount of mass.This mass lost is converted to energy.

The law of conservation of energy holds for this type of reaction (i.e the sum of mass and energy is remains the same in a nuclear reaction). Mass changes to energy, but the total amount of mass and energy combined remains the same before and after a nuclear reaction.

From the reaction above, the total decrease in mass = 236.053 - 235.868 = 0.185 u

Many grams of aluminum are required to produce 3.5 moles Al2O3 in the presence of excess O2?

Aleks [24]

The grams of aluminum that are required to produce 3.5 moles of AlO3 in presence of excess O2 is calculated as below

write the equation for reaction
4 Al + 3O2 =2 Al2O3

by use of mole ratio between Al to Al2O3 which is 4 :2 the moles of Al
=3.5 x4/2 = 7 moles

mass of Al = moles / x molar mass

= 7 moles x27 g/mol =189 grams
