Answer:

yes

Explanation:

it is very hot matter and solid, liquid and gas and plasma is the states of matter

Answer: Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. ... But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely. so True.

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.

A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory.

Nitrogen is one of the major elements that are cycled in nature. The major sink for nitrogen in nature is the atmosphere.

Biogeochemical cycles in nature show the diverse ways that elements move through the various spheres on earth.

Nitrogen is trapped from the atmosphere by nitrogen- fixing bacteria that live in the root noodles of leguminous plants which convert atmospheric nitrogen to nitrates. This nitrogen is transferred to living organisms when they eat those plants and become incorporated into biomass.

Decomposition returns this nitrogen in biomass to the soil. The action of denitrifying bacteria converts nitrates in soil back to atmospheric nitrogen. Also several anthropogenic sources release nitrogen into the atmosphere as NOx.

The atmosphere consists of 78% nitrogen hence it serves as the largest sink for nitrogen in nature.

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.

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.

Answer:-

the central part of an atom compsed of protons and neutrons.

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

b. boiling point

Explanation:

Water has a density of 1.0 g/mL. A plastic cup floats when it is placed into a container of water as it is less denser than water.

Density is a key notion in physics and material science that quantifies how tightly packed a substance's particles or molecules are within a certain volume. It is a measure of the mass contained in a certain amount of space that gives useful information about the properties of various materials.

It is vital to highlight that density is a material attribute that remains constant regardless of sample size. A little piece of iron, for example, has the same density as a huge iron block, despite the larger block having more mass.

Explanation:

As you know, a substance's specific heat tells you how much heat is required to increase the temperature of

of that sample by

C

.

In water's case, you know that its specific heat is equal to

C

. This tells you that in order to increase the temperature of  

1 g

of water by  

1

C

, you need to supply  

4.18 J

of heat.

How much heat would you need to increase the temperature of  

200 g

of water by  

1

C

?

Well, if you need  

4.18 J

per gram to increase its temperature by  

1

∘

C

, it follows that you will need  

200

times more heat to get this done.

Likewise, if you were to increase the temperature of  

1 g

of water by  

76

∘

C

, you'd need  

76

times more heat than when increasing the temperature of  

1 g

by  

1

C

.

Combine these two requirements and you get the total amount of heat required to increase the temperature of  

200 g

Explanation:

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.
