Select the correct statement or statements about compounds and molecules:

chose all that are correct

1) compounds don’t act like their elements; compounds act like a different substance.

2) a molecule can be made of one type of element or a mixture of elements.

3) a molecule is two or more atoms bonded together.

4) a compound is made of just one type of element.

1) and 3)

Step-by-step explanation:

Step-by-step explanation:

A compound is a molecule which is made of atoms from different elements.

Compounds are useful beacuse they don't actually act like their elements. For example, if you think about , you observe that it's a compund of 2 atoms of hydrogen and 1 atom of oxygen, but the compund doesn't act like hydrogen or oxygen, it's water. Therefore, the first choice is correct.

Now, as we said before, a molecule is form by atoms, specifically by two or more, because a single atom cannot form a molecule, it would be just an atom by itself. Therefore, the third choice is correct.

So, the right choices are 1 and 3.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

20
