The solution would be like this for this specific problem:

 

<span>1.0  </span>atm + 2.0 atm + 3.0 atm = 6.0 atm

 

So the partial pressure of the helium 3.0 atm.

You wish to add 5 mg/l naocl as cl2 to a solution in a disinfection test, and you have a stock solution (household bleach) that
Alecsey [184]

Answer: -

0.1 ml of bleach should be added to each liter of test solution.

Explanation:-

Let the volume of bleach to be added is B ml.

Density of stock solution = 1.0 g/ml

Mass of stock solution = Volume of stock x density of stock

                                     = B ml x 1.0 g/ml

                                     = B g

Amount of NaOCl in this stock solution = 5% of B g

                                     = \frac{5}{100} x B g

                                     = 0.05 B g

Now each test solution must be added 5 mg/l NaOCl.

Thus each liter of test solution must have 5 mg.

Thus 0.05 B g = 5 mg

                        = 0.005 g

B = \frac{0.005}{0.05}

  = 0.1

Thus 0.1 ml of bleach should be added to each liter of test solution.

Fill in the missing information:
Neko [114]

Answer: 1. Complete Nuclear Symbol : _{22}^{48}{Ti^{4+}}

2. Atomic number : 22

3. Mass number : 48  

4. Charge : 4 +

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neelectrons. utrons and number of protons.

Given : no of protons = 22 , thus atomic number = 22

Mass number =  number of neutrons + number of protons

Mass number =  26 + 22 = 48

Also for a neutral atom , the number of protons is equal to the number of electrons. But here electrons are 4 less than protons, which means the atom has lost 4 electrons and thus will have a charge of 4+.

The atomic number is specific to an element, and the element with atomic number 22 is Titanium (Ti). The representation is _{22}^{48}{Ti^{4+}}
