Explanation:

solid, liquids and gases are all made up of atoms and molecules

contrast

solids have a definite shape, liquids takes the shape of the container that contains it while gases do not have a shape

solids move about their mean positions, liquids move more freely while gases move in random motion

solids cannot be easily compressed, liquids can be compressed while gases can be easily compressed

Once of the skills necessary for this experiment is dilution. If you have 1.95 mL of .806 M bleach, what will be the new concent

aleksley [76]

<u>Answer:</u> The concentration of diluted bleach solution is 0.0157 M

<u>Explanation:</u>

To calculate the molarity of the diluted solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated bleach solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted bleach solution

We are given:

$M_1=0.806M\\V_1=1.95mL\\M_2=?M\\V_2=100mL$

Putting values in above equation, we get:

$0.806\times 1.95=M_2\times 100\\\\M_2=\frac{0.806\times 1.95}{100}=0.0157M$

Hence, the concentration of diluted bleach solution is 0.0157 M

The average American is looking at their phone for 6.25 hours a day. How many hours will the average American spend on their pho

julia-pushkina [17]

Answer:

177253.125hrs

Explanation:

Given parameters:

Number of hours spend per day on phone = 6.25hrs

Unknown:

Average hours pend by an average American if they lived for 77.7yrs

Solution:

Let us find the number of hours an average American spends on their phone per year;

there are 365days in a year

Number of hours = 365 x 6.25 = 2,281.25hrs

Now, if they lived for 77.7yrs;

They will spend = 77.7 x 2,281.25 = 177253.125hrs
