Environmental contingency plan is important to lessen or even prevent casualties or damage to infrastructures when unexpected environmental disasters happen. This is a common management strategy to lessen the costs of the company in the future. More importantly, it is used for safety purposes.
I think it is with screens l, chemicals, and filters
I hope this helped
Because as u go across groups the more reactive it is due to the ability of electrons to be given or taken away
Answer:
Explanation:
This is a typical double replacement or double decomposition reaction. In this kind of reaction, it involves the combination of ionic compounds which exchange their partners to form new compounds. Typical of these reaction is the formation of precipitates which are insoluble compounds.
The reaction equation is shown below:
AgNO₃
+ K₂SO₄
→ 2KNO₃
+ AgSO₄
)
From the rule of solubility:
- All trioxonitrate(v) salts are soluble
- Salts of silver sulfates are slightly soluble. This will form the precipitate in the solution.
We can write the ionic equation as:
Ag⁺
+ NO₃⁻
+ 2K⁺
+ SO₄²⁻
→ AgSO₄
+ 2K⁺ + NO₃⁻
The spectator ions or non-reactive ions are those ions that appears on both sides of the equation. These ions are the potassium and trioxonitrate ions. We cancel them out to give the net ionic equation of the reaction:
Ag⁺
+ SO₄²⁻
→ AgSO₄
Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:

Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:

m = 71x0.0200
m = 1.4200
