Sam wants to conduct an investigation of the velocity of a golf ball when hit off of the tee using the scientific method. Review

the procedural steps that Sam plans to follow during his investigation.
Collect data from a sample of ten golf balls hit off of the same tee by the same golfer.

Hypothesize that the golf ball will reach a velocity of 5 feet per second each time the ball is hit from the tee by the same golfer.

Observe the golf ball as it is hit off of the tee.

Analyze data using a table of data and graph of the data.

Communicate results based on the sample data collected.



Which of the following options represents the order of Sam’s procedural steps according to the scientific method?

Sam should plan to hypothesize about the velocity of the golf ball, observe the golf ball, collect data from a sample of golf balls, communicate the results based on collected data, and analyze the data.

Sam’s plan of procedural steps is correct.

Sam should plan to observe the golf ball, hypothesize about the velocity of the golf ball, collect data from a sample of golf balls, analyze the data, and communicate the results based on collected data.

Sam should plan to observe the golf ball, collect data from a sample of golf balls, analyze the data, hypothesize the golf ball’s velocity, and communicate the results based on collected data.

A drinking water plant adds 500 grams of fluoride to a water tank containing 500,000 liters of drinking water. what is the conce
nlexa [21]
Answer is: <span>concentration of fluoride in the water in parts-per-million is 1 ppm.
</span>Parts-per-million (10⁻⁶) is<span> present at one-millionth of a </span>gram per gram of sample solution, f<span>or example mg/kg.
</span>m(fluoride) = 500 g · 1000 mg/g = 500000 mg.
m(water) = d(water) · V(water).
m(water) = 1 kg/L · 500000 L.
m(water) = 500000 kg.
arts-per-million = 500000 mg ÷ 500000 kg = 1 mg/kg = 1 ppm.

Someone please do this!!!
Lilit [14]

Answer:

1) Fe = 69.9%

O = 31.1%

2) H = 5.19%

O = 16.5%

N = 28.9%

C = 49.5%

Explanation:

One easy way to do percent compositions is to assume you have 100g of a substance.

1) Lets say we have 100g of Fe2O3.

The total molar mass would be:

= 55.845*2+15.999*3 = 159.687

The molar mass of the Fe2 alone is:

=55.845*2 = 111.69

Thus, the grams of Fe2(out of a 100) could be calculated by multiplying 100g * the molar mass ratio of Fe2 to the whole:

= 100g *\frac{111.69}{159.687} = 69.9431

Which is approximately 69.9%.

We can find the amount of O3 by simply subtracting, as the rest of the compound is made of O3. Thus, the % composition of O3 is 31.1%

You can then do this same process to the next question, getting us the following:

H = 5.19%

O = 16.5%

N = 28.9%

C = 49.5%
