Picking up a paper clip with a magnet. Physical change, Chemical change, or neither

1 answer:

Hello there! :D

A physical change is a change in which something is changed in appearance. For example, if I cut a piece of paper in half.

A chemical change is when the composition (or the makeup) of something is changed. For example, baking soda and vinegar. They react to form a whole different thing.

Picking up a paper clip with a magnet doesn't change its appearance. It doesn't change its composition. The magnet only picks up the paper clip because it attracts magnetic objects, if you were to take it off of the paper clip it would still be the same paper clip, and most likely look the same.

I hope this helps!

How many L of a 7.5 H2SO4 stock solution would you need to prepare a dilute solution 100 L of 0.25M H2SO4

blsea [12.9K]

Answer:

3.33 L

Explanation:

We can solve this problem by using the equation:

C₁V₁=C₂V₂

Where the subscript 1 refers to one solution and subscript 2 to the another solution, meaning that in this case:

C₁ = 0.25 M

V₁ = 100 L

C₂ = 7.5 M

V₂ = ?

We input the data:

0.25 M * 100 L = 7.5 M * V₂

V₂ = 3.33 L

Thus the answer is 3.33 liters.

If 15 grams of Carbon dioxide is produced in a chemical reaction, how many grams of Carbon must be consumed in the reaction if w

Nata [24]

4.1g

Explanation:

Given parameters:

Mass of carbon dioxide = 15g

Mass of oxygen gas = 11g

Unknown:

Mass of carbon consumed = ?

Solution:

Equation of the reaction:

C + O₂ → CO₂

To solve this problem from the balanced equation, we have to use the amount of product formed and work to Carbon. This is because, we are sure of the amount of carbon dioxide formed but the amount of the given oxygen gas used is not precise.

Number of moles of CO₂ = $\frac{mass}{molar mass}$
