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.

GarryVolchara [31]

As per as the Multiplication rules of the significant figures, whenever any numbers in the decimals forms are multiplied or divided then result in mentioned in such a way so that the significant figures after the decimal will be same as that in the given least condition.


_______________________________


102900/12 = 8575


170 × 1.27 = 215.9


∴ (102,900 ÷ 12) + (170 × 1.27) =  8575 + 215.9


= 8790.9


Now, As per as Above rules, answer in correct significant figures will be = 8791.

Give all possible, accurate, correct IUPAC names for the following compounds:
Viefleur [7K]

Answer:

A. 4-ethyl-hex-3,5-dien-2-ol.

B. 2-chloro-3-methyl-5-<em>tert</em>-butylphenol.

Explanation:

Hello there!

In this case, according to the given problems, it is possible to apply the IUPAC rules to obtain the following names:

A. 4-ethyl-hex-3,5-dien-2-ol because we have an ethyl radical at the fourth carbon and the beginning of the parent chain is on the Me (CH3) because it is closest to first OH.

B. 2-chloro-3-methyl-5-<em>tert</em>-butylphenol: because we start at the alcohol and have a chlorine atom on the second carbon, a methyl radical on the third carbon, a <em>tert</em>-butyl on the fifth carbon and the parent chain is benzene which is phenol as an alcohol.

Regards!
