Which tools should be used to record the most complete data about gas

Chemistry
1 answer:
Zarrin [17]3 years ago
4 0
The tools that should be used to record the most complete data about a gas are a manometer and a thermometer.
Manometer is a device that measures pressure; therefore using this device the pressure of a gas may be determined. A manometer consists of a U shaped tube of glass filled with some liquid; normally mercury. Thermometer on the other hand measures the temperature of the gas. It measures temperatures in degrees, according to either the Celsius or Fahrenheit.

Describe how the metal probably increases the reaction rate, identify whether this is an example of homogeneous or heterogeneous
Lisa [10]

Answer:

The metal probably increases reaction rate by either holding reactant molecules in the correct orientation to react or by weakening or breaking bonds in reactant molecules to make them more reactive.

This is an example of heterogeneous catalysis.

It is heterogeneous catalysis because the catalyst is a solid and the reactants are gases. In heterogeneous catalysis, the catalyst is in a different phase than the reactants

Find the volume of an object that has a density of 3.14 g/mL and a mass of 52.9 g.
Natasha_Volkova [10]

Answer:

The answer is

<h2>16.8 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass of object = 52.9 g

density = 3.14 g/mL

The volume of the object is

volume =  \frac{52.9}{3.14}  \\   = 16.847133757...

We have the final answer as

<h3>16.8 mL</h3>

Hope this helps you

Add a constant temperature when the volume of the gas is decreased what happens to its pressure
Margaret [11]

Answer:

<h2>Pressure will increase</h2>

Explanation:

At a constant temperature, the pressure of gas will increase proportional to the decrease in volume of the gas.

P1V1= P2V2

Decrease in volume result in increase in pressure as the equation has to hold true.
