A bottle of coke is 250.0 mL. What is the volume in cubic centimeters?
hoa [83]

Answer:

The volume in cubic centimeters is 250

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So:

x=\frac{c*b}{a}

The direct rule of three is the rule applied in this case where there is a change of units. To perform this conversion of units, you must first know that 1 mL = 1 cubic centimeters. So, if 1 cubic centimeters is 1 mL, how many cubic centimeters equals 250 mL?

cubic centimeters=\frac{250 mL*1 cubic centimeters }{1 mL}

cubic centimeters= 250

<u><em>The volume in cubic centimeters is 250</em></u>

Explain the process of radioactive decay. What happens during the radioactive decay? What is the result at the end of radioactiv
nignag [31]

1) Radioactive decay is the spontaneous decomposition of the unstable nucleus of an atom.

2) The emission of a particle or a photon.

For example, alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus).

3) The result is usually more stable element with smaller atomic number.

For example, in alpha decay atom transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.

For example nuclear fission is radioactive decay process in which the nucleus of an atom splits into smaller parts and huge amount of energy is released.

I NEED HELP PLEASE! :)
Dmitrij [34]

Answer:

Explanation:

SF4 forms a trigonal bipyramidal shape and its molecular shape is that of a "see-saw".

Since sulfur is in 3rd period, it violates the octet rule and has more than 8 electrons accompanying its valence shell.

Here's a picture of lewis structure and electron geometry.
