Adding fertilizer to stimulate the aquatic plant growth, and putting research and money into renewable energy
Lelechka [254]2 years ago

Answer:putting research and money into renewable energy.

Explanation:

Increasing the lead emission is likely to cause pollution in air, water and soil.

Pouring petroleum to steams will also cause steams pollution.

Addition of fertilizers to stimulate plant growth will likely to increase the abundance of toxic chemicals in land and water which will lead to contamination of land and water. All these situations are responsible for damaging the environment.

Putting research and money into renewable energy will not cause damage to the environment. As the energy harnessed by the renewable sources of energy like solar energy, tidal energy, geothermal energy will not produce pollution.

Consider the formation of hcn by the reaction of nacn (sodium cyanide) with an acid such as h2so4 (sulfuric acid): 2nacn(s)+h2so
Artemon [7]

2NaCN(s) + H₂SO₄(aq) --> Na₂SO₄(aq) + 2HCN(g)  

The molar ratio between NaCN : HCN is 2:2  or 1:1

Mass of HCN = 16.7 g

Molar mass of HCN = 1 + 12 + 14 = 27 g/mol

Molar mass of NaCN = 49 g/mol

Therefore, the mass of NaCN is

16.7 g of  HCN x 49 g/mol of NaCN / 27 g/mol of HCN = 30.3 grams of NaCN

Therefore, 30.3 grams of NaCN gives the lethal dose in the room.

Convert 8.876 × 10^12 m^2 to units of km^2.
Darya [45]

Answer:

8.876\times 10^{18}\ km^2

Explanation:

In this problem, we need to convert 8.876 \times 10^{12}\ m^2 to km².

We know that,

1 km = 1000 m

⇒ 1 km² = 10⁶ m²

So,

8.876 \times 10^{12}\ m^2=8.876 \times 10^{12}\times 10^6\ km^2\\\\=8.876\times 10^{18}\ km^2

So, 8.876 \times 10^{12}\ m^2 is equal to 8.876\times 10^{18}\ km^2.
