Calculate the percent of each component in the mixture. Show your calculations. Circle final answers.

See Explanation

Explanation:

The question is incomplete; as the mixtures are not given.

However, I'll give a general explanation on how to go about it and I'll also give an example.

The percentage of a component in a mixture is calculated as:

Where

E = Amount of element/component

T = Amount of all elements/components

Take for instance:

In

The amount of all elements is: (i.e formula mass of )

The amount of calcium is: (i.e formula mass of calcium)

So, the percentage component of calcium is:

The amount of hydrogen is:

So, the percentage component of hydrogen is:

Similarly, for oxygen:

The amount of oxygen is:

So, the percentage component of oxygen is:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
