True, because the large covalent molecules would combine with the others
Answer:
<h3>The answer is 0.42 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 8.11 g
volume = final volume of water - initial volume of water
volume = 44.72 - 25.26 = 19.46 mL
We have
We have the final answer as
<h3>0.42 g/mL</h3>
Hope this helps you
In one mole of talc, we observe that there are:
3 moles of Mg
4 moles of Si
2 moles of H
12 moles of O
The molar ratio of O to Mg is then:
12 moles of O : 3 moles of Mg = 4 : 1
Therefore, if 6.1 moles of Mg are present, the moles of O are:
4 * 6.1 = 24.4 moles of O
The combination of seatbelts and airbags can reduce the risk of death in a collision by up to 80%.
The seatbelts help to keep the person in one position and prevent impact with the vehicle as the vehicle comes to a sudden stop. Moreover, the airbag increases the time of collision to reduce the impact experienced by the person. An increased time of collision greatly reduces the damage that is done to the body.
Mass and Volume!
