Question

1. this has definite shape and volume.
2. this is a state of matter with no definite shape or volume.
3. in the law of ____________ of matter, matter is not created nor destroyed in any chemical or physical change.
4. balance the following chemical equation. what number should be on the yellow line? fe + 3h₂so₄ → 1 fe₂(so₄)₃+ 3h₂
5. balance the following chemical equation. what number should be on the yellow line? 4nh₃ + 5o₂ → 4no + h₂o

Explanation:

Step1: Identify state of matter with definite shape and volume

Solids have definite shape and volume.

Step2: Identify state of matter with no definite shape or volume

Gases have no definite shape or volume.

Step3: Recall law of matter

The law is the law of conservation of matter.

Step4: Balance the Fe + H₂SO₄ equation

For the equation Fe + 3H₂SO₄ → 1Fe₂(SO₄)₃+ 3H₂, the coefficient of Fe should be 2.

Step5: Balance the NH₃ + O₂ equation

For the equation 4NH₃ + 5O₂ → 4NO + 6H₂O, the coefficient of H₂O is 6.

Answer:

1. Solid
2. Gas
3. Conservation
4. 2
5. 6
