Answer: Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. ...

Answers

The phrase that describes transmutation is ; ( A ) The conversion of an atom of one element into different element through nuclear changes.

Transmutation is simply the change of an element to another element, transmutation occurs at the nucleus of the atom of an element and this process is initiated through nuclear reaction ( radioactive decay ).

Therefore the conversion of an atom of one element into different element through nuclear changes summarizes the term "transmutation".

Hence we can conclude that the phrase that describes transmutation is  the conversion of an atom of one element into different element through nuclear changes.

Answers

Answer:

1.heterogeneous mixture

2.element

3.compound

4.homogeneous mixture

Explanation:

The correct pairs are:

A cloud, which consist of small water droplets - Heterogeneous mixture

Distributed throughout the air

helium, a gas composed of identical atoms - Element

Rubbing alcohol, a liquid composed of chemically bonded - Compound

Carbon, Oxygen, and Hydrogen atoms

sugar thoroughly dissolved in water - Homogenous mixture.

In Heterogenous mixture, the composition of the mixture is not uniform. In Homogenous mixture, the composition is uniform throughout. Element is the combination of same atoms. Compound contains two or more elements.

Therefore, the correct pairs are,

A cloud, which consist of small water droplets - Heterogeneous mixture

Distributed throughout the air

helium, a gas composed of identical atoms - Element

Rubbing alcohol, a liquid composed of chemically bonded - Compound

Carbon, Oxygen, and Hydrogen atoms

Answers

Aluminum forms an ion of +3 while the bromine atom form an ion of -1.

What is an ion?

An ion is an atom which has lost/gained one or more electrons. The ion will be positive if an electron is lost and will be negative when an electron is gained by the specie.

The ions formed by each of the species is;

Potassium iodide is an ionic compound.

Describe what happens, in terms of electron loss and gain, when a potassium atom reacts
with an iodine atom.

Answers

Answer:

In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).

Explanation:

pls mark as brainliest

In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.

What is oxidation ?

Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.

An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.

Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.

Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.

1. Does this chemical reaction follow the law of conservation of matter?

2. How many atoms of hydrogen do you have in the reactants? How many atoms of hydrogen to you have in the product?

3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?

Answers

1. No, it doesn't.

2. 4 Hydrogen atoms are on the reactants side and 2 hydrogen atoms on products side.

3. Because the mass of reactants is not equal to the mass of the products thus it doesn't follow the law of conservation of matter.

But on balancing the eqn,

CH4 + 2O2 > CO2 + 2H2O

The above eqn will follow the law of conservation of matter because the mass of reactants is equal to the mass of products.
