1. compare the information provided by a molecule’s chemical formula to the information provided by its structural formula.

2. what is the major difference between the two-dimensional and three- dimensional models of propane and ethene? when might you choose to use a two-dimensional model rather than a three-dimensional model when representing one of the molecules?

3. use the internet to research how chemists know that an oxygen molecule has unpaired electrons. summarize the reason in at least 2-3 sentences.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17

step-by-step explanation:

mark brainliest and have a great day!

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
