Answer:
<h2>volume = 3.63 mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
Since we are finding the volume
Making volume the subject we have
<h3>
</h3>
From the question
mass = 63.6 g
Density = 17.5 g/mL
Substitute the values into the above formula and solve for the volume
That's
<h3>
</h3>
We have the final answer as
<h3>volume = 3.63 mL</h3>
Hope this helps you
Answer:
the number of neutrons in an atom of the element is 10.
Explanation:
neutron: mass # -protons
neutron: 19 (18.9984 (rounded)) - 9
neutron: 19- 9 =10
whole number is equal to the number of protons.
Out of the following choices, the additional energy required for reactions to occur spontaneously is called the Eact or the Energy of Activation.
The partial pressure of carbon dioxide is 75 torr.
<h3>What is Dalton's theory?</h3>
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
- Total pressure of mixture = 825 torr
- Partial pressure of Nitrogen = 600 torr
- Partial pressure of oxygen = 150 torr
- Partial pressure of carbon dioxide = ?
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.
