Answer:

1. Acetic acid (CH3COOH): vinegar, acetate.

Acetylsalicylic acid (HOOCC6H4OOCCH3): aspirin.

Ascorbic acid (H2C6H6O6): vitamin C.

Carbonic acid (H2CO3): soft drinks, seltzer water.

Citric acid (C6H8O7): citrus fruits, artificial flavorings.

Hydrochloric acid (HCl): stomach acid.

2. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

3. In the chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.

4. pH < 7.

Sour taste (though you should never use this characteristic to identify an acid in the lab)

Reacts with a metal to form hydrogen gas.

Increases the H+ concentration in water.

Donates H+ ions.

Turns blue litmus indicator red.

5. Bitter taste (opposed to sour taste of acids)

Slimy, or soapy feel on fingers (Slippery)

Many bases react with acids and precipitate salts.

Strong bases may react violently with acids. ...

Bases turn red litmus paper blue.

Bases are substances that contain metal oxides or hydroxides.

6. The salt comes from weathering and volcanic activity. The ocean formed very early on in Earth history, as soon as water comes into contact with rock then weathering processes start – these leach (dissolve) the soluble elements preferentially out of the rock (sodium, calcium, magnesium, potassium etc).

7. Magnesium Sulfate, It is the product of the chemical reaction between magnesium hydroxide and sulfuric acid. In natural medicine, Epsom salts can be used as a laxative. A solution of the salts is used in many homes as a soak for foot aches, bruises and sprains. Some people enjoy using the chemical in their bath water.

8. Salt is white, odorless and it has a salty taste.

All potassium (K), ammonium (NH4+) and sodium (Na) salts are soluble in water (H2O).

Nitrites, nitrates, and bicarbonates can be dissolved in water.

All metallic oxides, metallic carbonates, hydroxides, phosphates, and sulphides are insoluble in water.

9. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

Hope this helps!

What was the relationship among human foragers and the environment/nature, and how was it different from our relationships to ot

ASHA 777 [7]

The relationship between the human foragers and the environment was much different than the one of the modern times. The foragers where directly dependent on the environment for their survival. They were not producing anything, so they were using the environment to get food and all the resources they needed. Nowadays, the relationship between the humans and the environment is much different, as most of the humans are directly dependent on the environment for the survival. This has led to have much less appreciation of it and very often even destroying it. The humans' relationship with the environment nowadays is much more recreational, scientific, or to use it for their further development.

A renowned fashion brand launches a line of evening wear while the economy is booming. How will this economic scenario influence

Ray Of Light [21]

Answer:

This economic scenario will increase the sales for the fashion brand's line of evening wear.

Explanation:

An economic boom occurs when the Gross Domestic Product (GDP) of a country increases. The GDP refers to the total or sum of all market values of products and services in a country for a particular time. The value measures the country's economic activity for that period.

At this time, businesses are very interested in investing. They also increase their production, which, in turn, affects the income of families. Once the production increases, the sales also increases because families are able to afford the items or services.

In the situation above, the fashion brand will most likely increase the sales because many people have the buying power for evening wears. People will be able to afford it because they have good income.
