Sodium hypochlorite chemical name would be NaOCl. Then, the molecular weight should be:23 + 16 + 35.5 = <span>74.5 g/mole

Molarity unit is mole of molecule divided by 1000ml of solvent, in this case water. Then for 32.4g of molecule with 499ml solvent it would be:
32.4g / (74.5g/mole) / (1000ml/499ml)= 0.87 m</span>

how many moles of sodium hydroxide (NaOH) are required to completely neutralize 2 mol of nitric acid (HNO3)
Brut [27]

2 moles of sodium hydroxide will be needed.

<h3><u>Explanation</u>:</h3>

Sodium hydroxide is a compound which is a base and nitric acid is the acid. The formula of the nitric acid is HNO3 and that of sodium hydroxide is NaOH.

The reaction between them are

NaOH +HNO3 =NaNO3 +H2O.

So here we can see that 1 mole of sodium hydroxide reacts with 1 mole of nitric acid to produce 1 mole of sodium nitrate and 1 mole of water.

So for 2 moles of nitric acid, 2 moles of sodium hydroxide will be required.

How does ur body maintain constant tempature on a hot day?
Lina20 [59]

It knows that when water evaporates, it carries heat energy away with it. 
So your body puts some water out on your skin, and hopes that it will
evaporate.  We call that "perspiring" or "sweating".

Based on lewis structure analysis, what is the formal charge of the central atom in clf3
MArishka [77]
Formal Charge is calculated as, Lewis structure is attached below,

Formal Charge  =  [# of valence electrons] - [electrons in lone pairs + 1/2 the                                     number of bonding electrons]

# of valence electrons of Cl  = 7

electrons in lone pairs  =  4

number of bonding electrons  =  6

Formal Charge  =  [7] - [4 + 6/2]

Formal Charge  =  [7] - [4 + 3]

Formal Charge  =  [7] - [7]

Formal Charge  =  0

Result:
           Formal charge on Cl in ClF₃ is zero.

When 125.0 g of ethylene (C2H4) burns in 60.0 grams of oxygen to give carbon dioxide and water, how many grams of CO2 are formed
gizmo_the_mogwai [7]

Answer:

             66 g of CO₂

Solution:

The Balance Chemical Reaction is as follow,

                             C₂H₂  +  5/2 O₂    →    2 CO₂  +  H₂O

Or,

                             2 C₂H₂  +  5 O₂    →    4 CO₂  +  2 H₂O    -------  (1)

Step 1: Find out the limiting reagent as;

According to Equation 1,

            56.1 g (2 mole) C₂H₂ reacts with  =  160 g (5 moles) of O₂

So,

                  125 g of C₂H₂ will react with  =  X g of O₂

Solving for X,

                      X =  (125 g × 160 g) ÷ 56.1 g

                      X =  356.5 g of O₂

It means for total combustion of Ethylene we require 356.5 g of O₂, but we are only provided with 60.0 g of O₂. Therefore, O₂ is the limiting reagent and will control the yield.

Step 2: Calculate Amount of CO₂ produced as;

According to Equation 1,

              160 g (5 mole) O₂ produces  =  176 g (4 moles) of CO₂

So,

                  60.0 g of O₂ will produce  =  X g of CO₂

Solving for X,

                      X =  (60.0 g × 176 g) ÷ 160 g

                      X =  66 g of CO₂
