The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: The equation was CaCO3 →CaO+CO2
He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer. Draw a model showing the number of each type of atom in the reactants and products. Use your model to explain your answer.

PLEASE HELP

A regular object has the following dimensions: Height 10cm, Length 13cm, Width 5cm. What is the volume of this object?

Answers

Answer:

650

Explanation:

To find the volume of an object, you need to multiply height x length x width

13 times 5 is 65

10 times 65 is 650

[tex]\text{Volume,} ~V= 10~ cm \times 13~ cm \times 5~ cm = 650 ~ cm^3[/tex]
