Which two models would be most useful in predicting weather?
A. A mathematical model based on data
B. A plastic model of a cloud
C. A map that shows wind patterns
D. A peach used to represent Earth

Answers

Answer:

A. A mathematical model based on data

A mathematical model based on data and a map that shows wind patterns   would be most useful in predicting weather as it they will provide data with most accuracy.

What is accuracy?

Accuracy in terms of chemistry can be defined as to how close a measurement is to the true value.There are three types of accuracy:

1) Point accuracy-It means accuracy is present at that point of scale only.It does not give any information about the accuracy of the instrument.

2)Percentage of true value--It is the accuracy  which is determined by identifying accuracy of the instrument  and comparing it with the measured true value.

3)Percentage of scale range- It is the accuracy  which determines accuracy of the measurement.

Accuracy in case of instruments  is neglected up  to ±0.5 percent.

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.

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
