sodium hydroxide (NAOH) a.k.a causic soda commonly used in labs​.

  • MOLAR MASS of naoh is 39.997 g/mol.
  • It is dry hard brittle, white stocks in large fused opaque white-stone like masses having a dense crystalline fracture in small pellets/flakes.
  • it is very delinquent  and one of the strongest base , acts as a saponifying agent which is used in industrial purposes.
  • It is an important industrial chemical as it is used on its own and is also used as a raw material in the production of other chemicals. The basis for the production of sodium hydroxide is the electrolysis of brine.

How many grams N2F4 can be produced from 225 g F,?​
zavuch27 [327]

Answer:

308 g

Explanation:

Data given:

mass of Fluorine (F₂) = 225 g

amount of N₂F₄ = ?

Solution:

First we look to the reaction in which Fluorine react with Nitrogen and make N₂F₄

Reaction:

          2F₂ + N₂ -----------> N₂F₄

Now look at the reaction for mole ratio

          2F₂     +    N₂   ----------->  N₂F₄

        2 mole                              1 mole

So it is 2:1 mole ratio of Fluorine to N₂F₄

As we Know

molar mass of F₂ = 2(19) = 38 g/mol

molar mass of N₂F₄ = 2(14) + 4(19) =

molar mass of N₂F₄ = 28 + 76 =104 g/mol

Now convert moles to gram

                 2F₂          +       N₂   ----------->  N₂F₄

        2 mole (38 g/mol)                        1 mole (104 g/mol)

                 76 g                                           104 g

So,

we come to know that 76 g of fluorine gives 104 g of N₂F₄ then how many grams of N₂F₄ will be produce by 225 grams of fluorine.

Apply unity formula

                  76 g of F₂ ≅ 104 g of N₂F₄

                   225 g of F₂ ≅ X of N₂F₄

Do cross multiplication

                  X of N₂F₄ = 104 g x 225 g / 76 g

                  X of N₂F₄ = 308 g

So,

308 g N₂F₄ can be produced from 225 g F₂

1. A(n)______________ bond forms when one atom gives up one or more electrons to another atom.
aalyn [17]

1. An____ionic____ bond forms when one atom gives up one or more electrons to another atom.

2. Atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are ions.

3. A_covalent__bond involves the sharing of electron pairs between atoms, also known as a molecular bond. 4. When one pair of electrons is shared between two atoms, a single bond is formed. 5. When two pairs of electrons are shared between two atoms, a double bond is formed. 6. A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms. As a result, one end of the molecule has a slightly negative charge and the other a slightly positive charge. 7. Atoms involved in a nonpolar covalent bond equally share electrons; there is no charge separation to the molecule. 8. A weak bond called a van der waals bond results from an attraction between a slightly positive region in a molecule and a slightly negative region in the same or a different molecule

What is the benefit of writing a net ionic equation instead of a formula equation?
brilliants [131]

Answer:

The correct option is The net ionic equation shows the spectator ions in the reaction.

Explanation:

The net ionic reaction will show us the ions which are involved in the reaction. It also helps us the charges present on each atom and how a reaction occurs due to these charges on atoms. It shows us that which ions actually take part in a chemical reaction and which ions do not take part in the reaction and are involved only for balancing the equation.

What did henry mosely do?, What did he discover and how it proved that mendeleev's period was valid?
Anettt [7]
Henry Mosely reorganized Mendeleev's periodic table so it would be in order of atomic number (number of protons) instead of in order by atomic mass. (I don't know the answer to the other 2 questions I apologize)
