N this experiment, you will observe the relationship between pressure and volume for gases at a constant temperature. You rememb

er that baking soda and vinegar react to form a gas. We will use this reaction in this experiment. Start by adding approximately twenty milliliters of vinegar to a bottle. Now you pour about half a teaspoon of baking soda into the balloon, using a funnel. Attach the end of the balloon to the top of the bottle. Carefully lift up the balloon up to let the baking soda fall into the vinegar in the bottle. Observe what happens.

Answer:

The balloon quickly becomes inflated because it is filled with CO2 gas

Explanation:

Once the vinegar and baking soda are mixed, a chemical reaction occurs as follows;

NaHCO3​+CH3​COOH→CH3​COONa+H2​O+CO2​.

Once this reaction occurs, the balloon becomes inflated because it is now filled with CO2 gas.

If the filled balloon is punctured at any point, CO2 gas escapes from it.

A sample of Neon is in a sealed container held under isothermic conditions. The initial pressure and volume are 2.7 atm and 4.5
Marina CMI [18]

Answer:

The final volume in mL is 7.14 mL or 7.1 mL.

Explanation:

1.Use Boyle's Law(P_{1} V_{1}= P_{2} V_{2}). Re-arrange to solve for V_{2}<em> for the final volume.</em>

<em />

<em>2. Plug in values. </em>V_{2} =\frac{(2.7 atm)(4.5 mL)}{(1.7 atm)}  = 7.14 mL

What is meant by polar molecule?

A polar molecule<span> has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from </span>polar<span> bonds arranged asymmetrically. Water (H</span>2<span>O) is an example of a </span>polar molecule<span> since it has a slight positive charge on one side and a slight negative charge on the other.</span>

CH4 and CH3CH2CH3 have the lowest boiling points because they experience only \rm CH_4 and \rm CH_3CH_2CH_3 have the lowest boil
ki77a [65]

Answer:

Dispersion forces

Relative molecular mass

Explanation:

Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.

If 2.1 moles of NaCl is dissolved in a solution with a total volume of 7.3 liters, what is the molarity of the solution? Round t
Arturiano [62]

Answer:

The molarity of the solution is 0.29 \frac{moles}{liter}

Explanation:

Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.

Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:

Molarity=\frac{number of moles of solute}{volume}

Molarity is expressed in units \frac{moles}{liter}.

In this case:

  • number of moles of solute= 2.1 moles
  • volume= 7.3 liters

Replacing:

Molarity=\frac{2.1 moles}{7.3 liters}

Molarity= 0.29 \frac{moles}{liter}

<u><em>The molarity of the solution is 0.29 </em></u>\frac{moles}{liter}<u><em></em></u>
