How many moles of ammonia gas are found in a 202 mL container at 35C and 750 mmHg

.0000787 mol

The subscripts of a compound indicate

the ratio of elements

A gas held at 798 mmHg in a 400 mL flask is released into a 3 L flask What will be the new gas pressure

106.4 mmHg

The ideal gas law measures pressure in

atmospheres A+

Omar was recording his preliminary data before beginning an experiment on gas behavior The room temperature was 298K and atmospheric pressure was 1 ATM Omar used an acceptable abbreviation of thes

STP

What is the best definition of manometer

an instrument that is used to measure gas in a closed container. A+

All gases have the ability to do what

Diffuse and compress

A baker uses the term one dozen to indicate a specific quantity 12 What quantity does the chemists term one mole indicate

6.02 x 10^23

Pressure is used to increase the volume of gas

Pressure is used to increase the volume of gas in Boyle's law.

Angelo noticed his lab partner had incorrectly recorded the pressure of a gas in mmHg rather than in atmospheres as their teacher requested When he corrected the mistake Angelo recorded 751.5 mmHg

the answer is 0.99 :)

Chen-liu has a sample of chlorine in a 10.00ml container at 25.00 and 0.9840 ATM if the gas is compressed to a volume of 7.600ml the temperature will rise to 26.00c and the resulting preassure will b

The resulting pressure will be 1.298 atm.

What correct method to test the odor of an unknown chemical

Test the odor from a reasonable distance and with small amounts of gas.

Choose the best definition of STP

a term that indicates a combined measurement of standard atmospheric pressure and room temperature. A+
