In the essay box, compose a scientific report which includes your observations, data, and conclusions. The following questions s

hould be answered in your conclusion.
Why does the first method for determining volume work only for a regularly shaped object?

Will the second method for determining volume work for any object or just an irregularly shaped one? Why?

Is one method of measurement more accurate than the other? Why or why not?

Would the displacement method of measurement work for a cube of sugar? What about a cork? Why or why not?

What did you find out from this investigation? Be thoughtful in your answer.

Answer:

1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included.

2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape.

3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve.

4. No, because the sugar would dissolve.

5. No, on this case the displacement method would not work because of the weight difference

Hydrocarbons are compounds that are composed of carbon and hydrogen. Which statement does the law of definite proportions suppor
lora16 [44]
The correct option is A.
The law of definite proportion states that a given chemical compound always contains its component elements in fixed ratio irrespective of the source they are obtain from.
For instance, water is made up of two atoms of hydrogen and one atom of oxygen. Water can not be formed in any other way. Combining the oxygen and the hydrogen in another ratio will give us another thing not water.

The balanced equation below represents the decomposition of potassium chlorate.
dezoksy [38]
The oxidation number of chlorine in the reactant can be determined by K ion and O ion. K ion is +1 and O ion is -2. And the Cl is +5. The gas has the greatest entropy and the solid has the least. In the production, there are solid and gas. So it has more entropy than the reactants with solid only.

what mass of copper is produce when Zinc is added to a solution containing 31.9g copper (ii) tetraoxosulphate (vi)​
Sergio [31]

12.7 grams of copper will be produced.

<h3><u>Explanation</u>:</h3>

Copper is placed below zinc in the metal activity series. This means zinc can replace copper from its salt. Here zinc is added to the salt solution of copper sulphate. The reaction involved is

CuSO4 +Zn =ZnSO4 +Cu.

Zinc sulphate is soluble in the solution and rose red copper will be precipitated from the solution.

From the chemical equation we can see that 1 mole of zinc replaces 1 mole of copper. As no mass of zinc added is mentioned we will assume that excess of zinc is added.

Atomic mass of copper = 63.5

Atomic mass of sulphur = 32.

Atomic mass of oxygen = 16.

So molecular mass of copper sulphate = 63.5 + 32 + 4\times16 = 159.5.

So, mass of 1 mole of copper sulphate is 159.5 grams.

So, in 31.9 grams of copper sulphate, number of moles of copper sulphate present =\frac {159.5}{31.9} = 0.2

In 1 mole of copper sulphate, 1 mole of copper is present.

So in 0.2 moles of copper sulphate, 0.2 moles of copper is present.

So mass of 0.2 moles of copper = 0.2\times63.5 = 12.7 grams

The terms dilute and concentrated referred to the ____ of a solution
valentina_108 [34]

Answer:

The correct answer is A) Concentration. See the explanation below, please.

Explanation:

We refer to concentration on the ratio between solute and solvent of a chemical solution. In the case of a more dilute solution, there is a higher proportion of solvent than solute and the opposite occurs in a concentrate.
