Chemistry

Explanation:

(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?

(Ans- A) Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.

(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?

(Ans-B) It will work for both regular and irregular shaped objects since both displace equal volumes of water.

(Ques - C) Is one method of measurement more accurate than the other? Why or why not?

(Ans-C) Both are pretty accurate, with some experimental errors which may creep in accidentally.

(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?

(Ans - D) No, the method would not work because sugar being soluble, will dissolve in water.

No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.

(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.

(Ans- E) I learnt about determining volume of different objects from this investigation. (Sorry, I know its not a very thoughtful answer)

What is the volume of an object with a mass of 31g and density of 444g/ml

Tanzania [10]

Answer:

<h2>The answer is 0.07 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 31 g

density = 444 g/mL

We have

$volume = \frac{31}{444} \\ = 0.06981...$

We have the final answer as

Dalton's Atomic Model

olga_2 [115]

Answer:

A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed. Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.

John Dalton developed a crude method for measuring the masses of the elements in a compound. His law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.

How do you convert kilograms to pounds?

Maru [420]

Answer: (1 Kilogram = 2.20462 pounds) . There are 2.2046226218 lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2.205 for an approximate result. 1 kilogram is also equal to 2 lb and 3.27396195 oz. Working out a rough estimate in your head for converting to pounds and ounces may be tricky - remember that there are 16 ounces in a pound.
