Which property describes a mixture? It cannot be separated by physical methods. It has a single chemical composition. It cannot have more than one state of matter. It cannot be described by a chemical symbol or formula.

Answers

Answer:

it cannot be separated by physical methods

Explanation:

The mixture is not separated from the physical methods. Thus, option A is correct.

A mixture has been the combination of two or more substances. It has been described as a homogeneous solution.

The constituents in the mixture are indispensable. The mixture is generally homogeneous, however, heterogeneous mixtures have been possible with the substances being separated.

The mixtures have a different chemical composition and are not separated from the physical methods. Thus, option A is correct.

Where does the force come from when a bumper car changes speed?

Answers

Answer:

Newton's second law

Explanation:

The rate of change of momentum of an object is equal to the net force acting on it. When bumper cars collide they push on each other. These pushes cause the momentum of each car to change.

A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH? 1 3 6 11

Answers

Answer:

6

Explanation:

Answer:

6

Explanation:

Obi is trying to determine if a powdery, solid substance is an element or a compound. After recording some observations, he strongly heats a sample of the solid over a burner flame. After fifteen minutes, he turns off the flame and allows the sample to cool. He records his final observations in the data table.

A 3-column table with 3 rows. The first column labeled observation has entries appearance, mass (g), chemical reaction with weak acid. The second column labeled original sample has entries white solid, 100.0, bubbles. The third column labeled sample after heating has entries white solid, 56.0, no bubbles.
Which is the best explanation of his results?

A. The heating changed some of the sample to gas, causing the mass to decrease without breaking down the sample. Therefore, the original sample is a compound.

B. The appearance stayed the same, showing that the sample was not broken down by heating. Therefore, the original substance is an element.

C. The mass decreased during heating and some of the impurities escaped. Therefore, the original substance is an element.

D. The chemical reaction with acid changed, showing that the sample was broken down by heating. Therefore, the original substance is a compound.

Answers

An element consists of one type of atom and cannot be broken into simpler substances through simple chemical processes

The correct option is option D

D. The chemical reaction with acid changed, showing that the sample was broken down by heating. Therefore, the original substance is a compound

The reason why option D is correct is as follows:

The given table is presented as follows;

[tex]\begin{array}{|l|l|l|}\mathbf{Observation}&\mathbf{Original \ Sample}&\mathbf{Sample \ After \ Heating}\\Appearance&White \ solid&White \ solid\\Mass&100 \, g&56 \, g\\Chemical \ reaction \ with \ acid&Bubbles&No \ bubbles\end{array}\right][/tex]

Given that the changes after heating includes lack of visible reaction with the weak acid, and a significant change in mass, therefore;

The original substance was broken down by heat resulting in a new substance that has different chemical properties. An element cannot be broken down into simpler substances. Therefore, the substance is a compound

The correct option is option D

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
