A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73 atm producing a new volume of 751 mL. What was its original

volume?
Chemistry

Answer:

This is probably too late but the answer is 351

Explanation:

0.73x751=548.23

After getting both new pressure and new volume and having only one original pressure which is 1.56 you´ll have to divide 548.23 by 1.56 and you´ll end up with 351 which should be the original volume.

Which statements correctly describe atmospheric pressure?
Shalnov [3]

Answers are:

2. It pushes on all objects that are on Earth’s surface.

3. It can be measured in atmospheres or kilopascals.

Barometric pressure (atmospheric pressure), is the pressure within the atmosphere of Earth

Atmospheric pressure decreases with increasing height, because there are fewer air molecules above a given object.

Barometer is an instrument used in meteorology to measure atmospheric pressure.

Atmospheric pressure (atm) is the force per unit area by the weight of air above that point.  

Kilopascal (kPa) is a metric system pressure unit and equals to 1000 force of newton per square meter.

Atmospheric pressure results from molecular collisions of atmospheric gases.

How can you described the energy of a storm
lakkis [162]

Answer:

When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.
