The changes in matter/energy can be classified as follows:

Physical changes - Crystallizing salt from seawater
Chemical changes - ripening fruit
Nuclear changes - production of elements in the stars

<h3>What are physical, chemical and nuclear changes?</h3>

Matter and energy undergo physical, chemical and nuclear changes.

Physical changes are changes in which no new product is formed.

Chemical changes are changes in which no new product is formed.

Nuclear changes are changes in which no new product is formed.

Examples of each of the given changes is as follows:

Physical changes - Crystallizing salt from seawater
Chemical changes - ripening fruit
Nuclear changes - production of elements in the stars

Therefore, matter/energy undergo changes.

What is the molar mass of carbon monoxide (in units of g/mol)? Use two decimal places in atomic masses. Only give the numeric va

ikadub [295]

ANSWER

The molar mass of carbon monoxide is 28g/mol or 2.8 x 10^1 g/mol

EXPLANATION

Given that

The chemical formula of carbon monoxide is CO

Note that, the unit mass of carbon is 12.01u and the unit mass of oxygen is 15.99u

Based on the atomic masses of the elements, we can now find the molar mass of CO

$\begin{gathered} \text{ CO = \lparen1 }\times\text{ 12.01\rparen + \lparen1 }\times\text{ 15.99\rparen} \\ \text{ CO = 12.01 + 15.99} \\ \text{ CO = 28g/mol} \\ \text{ CO = 2.8}\times\text{ 10}^1\text{ g/mol} \end{gathered}$

Therefore, the molar mass of carbon monoxide is 28g/mol or 2.8 x 10^1 g/mol
