Answer: The volume of 9.7 tons of given ethylene glycol is 0.0079 .
Explanation:
Given: Density = 1.11
Mass = 9.7 tons
Convert tons into lb as follows.
Now, lb is converted into kg as follows.
1 kg = 1000 g
So, 8.79 kg = 8790 g
Density is the mass of a substance divided by its volume. Hence, volume of ethylene glycol is calculated as follows.
Thus, we can conclude that the volume of 9.7 tons of given ethylene glycol is 0.0079 .
The answer is C, the particles collide more and have more energy
Answer:
Because it is made up of different minerals which are chemically combined.
Explanation:
We are given with a theoretical amount of 9 grams of product but the student only got 7.8 grams. To calculate the percent yield, we divide the experimental amount by the theoretical amount. In this case, we divide 7.8 grams by 9 grams and multiply by 100 percent. The answer is equal to 86.67 percent.
Answer:
<h3>The answer is 4 N</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 2
We have the final answer as
<h3>4 N</h3>
