Answer:
The new volume is 87.5 ml.
Explanation:
We have,
Volume of sample of neon is 175 ml
The pressure changed from 75 kPa to 150 kPa.
We need to find new volume.
It is based on the concept of Boyle's law. Let V₂ is new volume. So,
So, new volume is 87.5 ml.
Answer: These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine.
Explanation:
<span>As mentioned, the isomerization of cyclopropane to propylene is a first-order process with a half-life of 19 min at 500°c. A first-order reaction kinetic rates means that the rate is constant throughout the reaction.
Thus, the time it takes for the partial pressure of cyclopropane to decrease from 1 atm to 0.125 atm at 500°c is </span><span>57 minutes.</span>
The appropriate answer is c. Scientists get the information from past climates by melting ice cores retrieved from boring the ice and retrieving cores. The air is trapped in the ice as little bubbles and as the ice melts the gases are retrieved. Ice cores are taken from regions such as the Greenland ice sheets. Scientists have tested air samples thousands of years old.
Answer:
density = 7.83g/mL
It will sink in water.
Explanation:
D = mass/volume
94/12 = 7.83 g/mL
density of water is 1g/mL
Object is more dense than water, meaning it will sink.
