Answer:
248.4 mL
Explanation:
In order to answer this problem we can use <em>Boyle's law</em>, which states that at a constant composition:
Where in this case:
We <u>input the data</u>:
- 762.7 torr * 229.5 mL = 704.5 torr * V₂
And <u>solve for V₂</u>:
Answer:
Limestone is easily eroded from above and below.
Explanation:
The Florida bedrock is largely made of limestone. Because limestone is a rock that is easily eroded, the landscape of a great part of Florida is classified as karstic.
Karstic landscapes are dotted by sinkholes, underground rivers, caves, and springs. The more acidic the groundwater or rainwater, the faster and more easily the limestone will succumb to erosion.
In this way, underground rivers, streams, runoff, rain, and underground water pooled in caves have all carved out gaps and caverns in the weak limestone bedrock.
Answer:
Explanation:
Artificial or induced transmutation occurs when atoms of one element are struck with particles in a linear accelerator, cyclotron, or synchrotron. ... With this process, some of the protons from the bombarding particles are lodged in the target nucleus, promoting the transmutation into a different element.

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go.
