Question

Cy 1. Тірі ағзалардың ылғалға, дыбысқа, ауаның газ құрамына, химиялық заттарға беретін реакциясына мысал келтіріңдер? ​

Answer 1

Ответ:

Мысалы, қызғалдақ жарық бар кезде гүлін жаяды,қараңғы уақытта жабады. Бақбақ, ылғалды ауа райында гүлшоғырын жауып алады,ашық күні жайып тұрады. Мимоза, жапырағына қолың тиіп кетсе, тез арада жиырылып, басын төмен салбыратып алады да, біраздан кейін бұрыңғы қалпына келеді.

Reactions of acids with different substances

Acids are known for their ability to react with various substances, leading to different outcomes. Here are some examples of reactions involving acids:

1. Reaction with metals: Acids can react with certain metals to produce hydrogen gas and a salt. For example, when hydrochloric acid (HCl) reacts with zinc (Zn), it produces zinc chloride (ZnCl2) and hydrogen gas (H2) [[1]].

   2HCl + Zn → ZnCl2 + H2
   

2. Reaction with bases: Acids and bases can undergo a neutralization reaction, resulting in the formation of water and a salt. For instance, when hydrochloric acid reacts with sodium hydroxide (NaOH), it forms water (H2O) and sodium chloride (NaCl) [[2]].

   HCl + NaOH → H2O + NaCl
   

3. Reaction with carbonates and bicarbonates: Acids can react with carbonates and bicarbonates to produce carbon dioxide gas, water, and a salt. For example, when hydrochloric acid reacts with sodium carbonate (Na2CO3), it produces carbon dioxide (CO2), water (H2O), and sodium chloride (NaCl) [[3]].

   2HCl + Na2CO3 → CO2 + H2O + 2NaCl
   

4. Reaction with metals oxides: Acids can react with metal oxides to form salt and water. For instance, when sulfuric acid (H2SO4) reacts with copper(II) oxide (CuO), it produces copper(II) sulfate (CuSO4) and water (H2O) [[4]].

   H2SO4 + CuO → CuSO4 + H2O
   

5. Reaction with ammonia: Acids can react with ammonia (NH3) to form ammonium salts. For example, when hydrochloric acid reacts with ammonia gas, it forms ammonium chloride (NH4Cl) [[5]].

   HCl + NH3 → NH4Cl
   

These are just a few examples of the reactions that acids can undergo with different substances. Acids have diverse chemical properties and can participate in various reactions depending on the specific acid and the substance it interacts with.
