What is the correct noble gas configuration for oxygen?

Answers

Oxygen (O) is a chemical element which you're surely familiar with since you breathe it every second of your life. The noble gas configuration is [He] 2s2 2p4. This shows that there is a total of 8 electrons (two in the 1s orbital, another 2 in the 2s orbital and the rest in the 2p orbital)

The maximum allowable concentrationof lead in drinking water is 9.0 ppb. If 2.0
X 10 grams of lead is present in 250
mL of water, is it safe to drink the water?
Support your answer with mathematical
proof.​

Answers

We are given:

Maximum concentration of Lead in water = 9 ppb

Mass of Lead in the given solution = 20 grams

Volume of water in the given solution = 250 mL

What is 1 ppb?

1 ppb, short for parts-per-billion. As from its name itself, ppb is used to find how many molecules of solute are present per 1 Billion molecules of the solvent

you can also use it in grams to get the formula:

1 ppb = 1 gram of solute / 1 Billion grams of Solvent

Finding the Ideal ppb concentration:

We are given that the maximum allowed concentration is 9 ppb

which means that we need 9 grams of the solute per 1 Billion grams of Solvent:  9 grams of Solute / 10⁹ grams of Solvent

ppb Concentration of the given solution:

We have 20 grams of Solute in 250 mL of water

Since the density of water is 1 gram/mL

20 grams of Solute / 250 grams of Solvent

As we can see, this fraction is FAR more large that the maximum ppb concentration

This means that the concentration of Lead in the Given solution is higher than the maximum amount and Hence, is unfit to drink

A 14 wt% solution of cacl2 (110.98 g/mol) has a density of 1.126 g/ml. what is the mass (in milligrams) of a 20.0-ml solution of 14.0 wt% cacl2?

Answers

Density = mass / volume

Thus, Mass of the solution can be expressed as:

Mass of solution = Density of solution × volume of solution

Given- Density of solution = 1.126 g/ml

volume of solution = 20.0 ml

∴ Mass of 14 wt% solution of CaCl2 = (1.126 g/ml) × (20 ml)

                                                           = 22.52 g

                                                           = 22520 mg

In a lab experiment 80.0 g of ammonia [NH3] and 120 g of oxygen are placed in a reaction vessel. At the end of the reaction 72.2 g of water are obtained. Determine the percent yield of the reaction.

Answers

The percent yield of the reaction : 89.14%

Further explanation

Reaction of Ammonia and Oxygen in a lab :

4 NH₃ (g) + 5 O₂ (g) ⇒ 4 NO(g)+ 6 H₂O(g)

mass NH₃ = 80 g

mol NH₃ (MW=17 g/mol):

(80)/(17)=4.706

mass O₂ = 120 g

mol O₂(MW=32 g/mol) :

\tt (120)/(32)=3.75

Mol ratio of reactants(to find limiting reatants) :

\tt (4.706)/(4)/ (3.75)/(5)=1.1765/ 0.75\rightarrow O_2~limiting~reactant(smaller~ratio)

mol of H₂O based on O₂ as limiting reactants :

mol H₂O :

\tt (6)/(5)* 3.75=4.5

mass H₂O :

4.5 x 18 g/mol = 81 g

The percent yield :

\tt \%yield=(actual)/(theoretical)* 100\%\n\n\%yield=(72.2)/(81)* 100\%=89.14\%

16. Which of the following properties of the elements remain unchanged across#period
A lonivation energy
C Electro negativity
13. Number of shells
D. Nuclear charge​

Answers

Answer:

Number of shells

Explanation:

Across the period on the periodic table, the number of shells remains the same. There is no variation or trend for the number of shells on a period.

  • The number of shell is the energy level corresponding to an atom.
  • As we go from period to period, the energy level increases by 1.
  • The period number corresponds to the number of shells.
  • Elements in period 4 will have 4 shells.
  • There is no variation of any sort in the number of shell across a period.
