A student was directed to convert the mass of a boulder from kg to pounds.

Chemistry
1 answer:
Alina [70]3 years ago
5 0

Answer:

Incorrect

Explanation:

Given that,

The mass of a boulder, m = 22 kg

We need to find the weight of the student in pounds.

We know that,

1 pound = 454 g

or

1 g = (1/454 pounds)

22 kg = 0.022  grams

So,

0.022 grams = \dfrac{0.022}{454}\ pounds

= 0.000048 pounds

The student says the weight is 0.048 pounds. It means he was incorrect.

Represent the decomposition of aluminum oxide using the same number of atoms of molecules as are
pantera1 [17]

Answer:

Decomposition of aluminium oxide forms  aluminium atoms and  oxygen atoms.

Explanation:

<u>Decomposition reaction:</u>

When a single compound break down into two or more simpler products.

For example "AB" reactant undergoes decomposition to form "A" and "B" products.

The chemical reaction is as follows.

AB\rightarrow A+B

The given compound is aluminium oxide.

The decomposition reaction of aluminium oxide is a follows.

Al_{2}O_{3}\rightarrow Al+O_{2}

The balanced equation is as follows.

2Al_{2}O_{3}\rightarrow 4Al+3O_{2}

Therefore, Decomposition of aluminium oxide forms aluminium atoms and  oxygen atoms.
