If a glass of water is left in open air for two days, what changes would it undergo in terms of

Chemistry
1 answer:
kykrilka [37]1 year ago
7 0

Answer: When you leave a glass of water uncovered for 2 days, carbon dioxide in the air starts to mix with it causing the pH to lower, therefore worsening the taste (quality). Also, there will most likely be bacteria and dust floating around in it. Some of the water will eventually evaporate and turn into a gas called water vapor, therefore decreasing the amount of water in the glass (quantity).

Explanation: Hope this helps!

How is stoichiometry used to calculate the amount of product from amount of reactant?
IceJOKER [234]
<span>Stoichiometry deals with the quantitative measurement of reactants and products in a chemical reaction. Let suppose you are given with following reaction;

                                            A  +  2 B   </span>→    3 C

According to this reaction 1 mole of A reacts with 2 moles of B to produce 3 moles of C. Now using the concept of mole one can easily measure the amount of reactants reacted and the amount of product formed, as...

                    1 Mole Exactly equals 6.022 × 10²³ particles

                    1 Mole of Gas (at STP) exactly occupies 22.4 L Volume

                    1 Mole of any compound exactly equals the molar mass in                                 grams

Therefore, <span>Stoichiometry is very helpful in quantitative analysis.</span>
