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

.0000787 mol

On a trip to Italy Cheyne rented a car to tour the country As he turned onto the highway he noticed that the speed limit was 95 kmh How fast can Cheyne drive in mph

Cheyne can drive 59 mph.

The subscripts of a compound indicate

the ratio of elements

Acid is correctly diluted with water by this method

adding acid to the water

The ideal gas law measures pressure in

atmospheres A+

Stella described her chemistry notebook as being a green rectangle with curved edges It measured 30.0 cm x 22.1 cm What kind of properties did Stella describe

physical properties (:

Classify this property as homogenous or heterogenous Click on the correct answer

homogeneous

Consistent temperature can be achieved while heating a test tube by doing what

Consistent temperature can be achieved by heating a test tube while moving the test tube all around the flame. Do not let only one part of the test tube rest on a flame but instead, keep moving the test tube slowly.

All gases have the ability to do what

Diffuse and compress

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.
