[i assume you meant grams and not gallons in this but I could be wrong...anyways] the formula to find density is

d=m÷v

in your case it will be:
d=40.5÷15.0

this will give you a density of 2.7 g/mL^2

Hello!

I'm going to have to infer that you meant "grams" and not "gallons" :-)

Anyways, to find the density, you need to the divide mass over volume (d = m/V).

Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.

40.5 grams / 15.0 mL = 2.7 g/mL

Therefore, the density of the aluminum block is 2.7 grams per milliliter.

sesenic [268]

Answer:

Beta emission

Explanation:

In beta emission, a neutron is converted into a proton thereby emitting an electron and a neutrino. A neutrino is a particle that serves to balance the spins.

When a nucleus undergoes beta emission, the mass number of the parent and daughter nuclei remain the same while the atomic number of the daughter nucleus is greater than that of its parent by one unit.

Hence, in beta emission, the daughter nucleus is found one pace to the right of the parent in the periodic table.

Tatiana [17]

Answer:

2-propanol

Explanation:

From the given information

2 drops of an unknown sample were said to be placed in a test tube followed by the addition of 2 ml of ethanol then gentle mixing. They then initiate a further addition of  2 drops of potassium permanganate reagent (KMNO₄) to the test tube and mixed the contents of the test tube thoroughly. After adding 2 drops of potassium permanganate reagent, the reagent oxidizes the secondary alcohols(2-propanol) to ketone(i.e acetone) and no further reaction will take place since there are no reactive C-H bonds left. The diagram attached below shows how the reaction proceeds.
