Answer:  -2m/s2

Explanation:

Using the following equation ; acceleration = Change in velocity / time

i.e  a =  v - u / t

where  'a'  = acceleration

              v  = final velocity

              u  =  initial velocity

              t   =  time

Therefore;  from the graph we have acceleration to be, 0 - 6m/s / 3s  = -2m/s2

Place the following compounds in order of increasing strength of intermolecular forces. Ch4 ch3ch2ch3 ch3ch3
Nikitich [7]

Explanation:

More is the mass of an alkane molecule more will be its boiling point. This means that forces of attraction will be more when mass is more as more heat is required to break the bonds within atoms. Hence, boiling point is more.

Therefore, in the given molecules mass of CH_{4} is 16.04 g/mol, mass of CH_{3}CH_{2}CH_{3} is 44 g/mol, and mass of CH_{3}CH_{3} is 30 g/mol.

Thus, we can see that CH_{3}CH_{2}CH_{3} has the highest mass and CH_{4} has least mass.

Hence, increasing strength of intermolecular forces of given compounds is as follows.

             CH_{4} < CH_{3}CH_{3} < CH_{3}CH_{2}CH_{3}

Lady_Fox [76]

4 moles of sugar.

Explanation:

A mole is defined as the amount of a substance contained in Avogadro's number of particles 6.02 x 10²³.

    1 mole of substance  = 6.02 x 10²³. molecules

Given that;

  the sample of sugar contains 1.505 x 10²³.molecules

  The number of moles in this amount of sugar is 4 moles

How many 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each?
Dima020 [189]

1 tablespoon = 0.5 ounces

We are required to find for 2 table spoons.

2 table spoons = 2 x 0.5 = 1 ounce.

Each bottle has 16 ounce.

Number of bottles = 4

So total number = 4 x 16 = 64 ounces.

Number of 2 table spoons = \frac{64 ounce}{1 ounce}

= 64

Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.
