Answer:

The correct option is d

Explanation:

There are several ways of harmlessly disposing chemical wastes and as such some chemical wastes have special disposal methods (for example hazardous wastes such as inflammable wastes, corrosive wastes and poisonous wastes).

For the reasons above, it is necessary for the teacher's instruction to be followed in disposing the waste because the teacher will have a better knowledge of the class of waste and the best method to harmlessly dispose such waste (most especially because of the large waste produced) .

<span>In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. Balanced chemical equation for this reaction is given below. Na-sodium , H2o- water, H-hydrogen gas and NaOH- aqueous sodium hydroxide. Two atoms of Na react with two atoms of water and this reaction will give us H (hydrogen gas) and two atoms of NaOH (aqueous sodium hydroxide). 2Na + 2 H2o = H2 +2NaOH.</span>

27. Sample of neon gas has a pressure of 4.1 atm and argon gas with a pressure of 3.2 atm are added to a
MrRa [10]

Answer:

Option C. 13.5 atm

Explanation:

From the question given above, the following data were obtained:

Pressure of Neon (Pₙₑ) = 4.1 atm

Pressure of Argon (Pₐᵣ) = 3.2 atm

Pressure of nitrogen (Pₙ₂) = 6.2 atm

Total pressure (Pₜ) =?

The total pressure in the container can be obtained by adding the pressure of the individual gases. This is illustrated below:

Pₜ = Pₙₑ + Pₐᵣ + Pₙ₂

Pₜ = 4.1 + 3.2 + 6.2

Pₜ = 13.5 atm

Therefore, the total pressure in the container is 13.5 atm

Suppose the half-life of element k is 20 minutes. if you have a 200 g sample of k, how much of element k will be left after 60 m
vodka [1.7K]
T=20 min
m₀=200 g
t=60 min

the mass of element through time t is:
m=m₀*2^(-t/T)

m=200*2^(-60/20)=25 g

25 grams of element will be left after 60 minutes
