Negative radical in the periodic table<br>​
AVprozaik [17]

Answer:

Negative Radicals ---→

1).Flouride =  F⁻

2). Chloride = Cl⁻

3) Bromide = Br⁻

4) Iodide = I⁻

5) Sulphate = SO₄²⁻

6) Oxide = O²⁻

7) Nitride = N³⁻

8) Sulphur = S²⁻

9) Carbide = C⁴⁻

10) Hydroxide = OH⁻

11) Nitrate = NO₃⁻

12) Carbonate = CO²⁻

13) Hydrogen Carbonate = HCO₃⁻

14) Sulphate = SO₄²⁻

15).Sulphite = SO₃³⁻

16) Nitrate = NO₃⁻

17)Nitrite = NO₂⁻

18) Hydrogen Sulphite = HSO₃⁻

19) Hydrogen Sulphate = HSO₄⁻

20) Chromate = CrO₄²⁻

There are lot of Radicals which cannot be easily written. Although some of the Important Radicals which are commonly used are mentioned above.

Hope it helps,

A system at equilibrium has two aqueous products and two aqueous reactants. An additional amount of one of the products is added
devlian [24]

Answer: c. the amounts of the reactants

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given reaction:

A(aq)+B(aq)\rightleftharpoons C(aq)+D(aq)

If the concentration of one of the products is increased, so according to the Le-Chatelier's principle, the equilibrium will shift in the direction where decrease of concentration of product takes place. Therefore, the equilibrium will shift in the left direction i.e. towards the reactants and thus more reactants will be formed.

Why would increased levels of greenhouse gases contribute to higher temperatures on earth
valentina_108 [34]
Greenhouse gases are the gases in the atmosphere that keep the air in the atmosphere. It also traps the sun's sunlight. Since the heat is trapped in here, it would contribute to higher temperatures. *Have a nice day!!*
