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.

Calculate the density of an object with a mass of 6.147 and a volume of 9.3 (include units)
Olin [163]
Here is the formula for density:
Density (D) = Mass (M) divided by Volume (V)

So you would do D = 6.147 divided by 9.3

As an as answer you would get: 0.6609677419g/cm^3

Additional information:

The formula for volume is:
V = M divided by D


The formula for Mass is:
M = D times V


I hope this helps :)

Masja [62]

Answer:

The atomic mass of the boron atom would be <em>10.135</em>

Explanation:

This is generally known as relative atomic mass.

Relative atomic mass or atomic weight is a physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass of 1/12 of the mass of a carbon-12 atom. Since both quantities in the ratio are masses, the resulting value is dimensionless; hence the value is said to be relative and does not have a unit.

<em>Note that the relative atomic mass of atoms is not always a whole number because of it being isotopic in nature.</em>

  • <em>Divide each abundance by 100 then multiply by atomic mass</em>
  • <em>Do that for each isotope, then add the two result. Thus</em>

Relative atomic mass of Boron = (18.5/100 x 11) + (81/100 x 10)

                                                 = 2.035 + 8.1

                                                 = 10.135

Answer:

I believe- If there is more metal for the magnet to reach for, then the strength will grow but it may be harder to pick up off of a surface depending on the weight of the nail. If it is a light nail, it would be more efficient for a quick result in having the magnet to pick it up
