Chemistry
1 answer:
xenn [34]3 years ago
3 0

(NH4),CO

(NH₄)₂ CO₃  

Explanation:

The chemical formula for ammonium carbonate is (NH4),CO

Ammonium carbonate is made up of:

  Ammonium ion

  Carbonate ion

Ammonium ion is represented by NH₄⁺

Carbonate ion is represented by CO₃²⁻

Now to write the formula, we are going to use their combining powers;

                   

                              NH₄⁺                     CO₃²⁻  

Combining

power                       1                             2

Exchange

of power                    2                            1

  Formula of compound              (NH₄)₂ CO₃

iren [92.7K]

Answer:

The pricing strategy is an important element in setting up the selling price of a product.

Explanation:

The pricing strategy is an important consideration while fixing up the selling price of product manufactured. When setting up a selling price of a product, the companies set up product calculation. Businesses should decide the pricing strategy before they advertise the products to the customers.  

There are mainly 5 benefits to the businesses while doing a product calculation. They are:

--- Doing competition based pricing enables the company to compete with the rival companies product and is based on the market based study. Competition pricing is a useful tool for the retailers as well as the small businesses.

---  Doing a cost plus pricing helps the total cost of making the product and also an add up in the market in order to determine the pricing of the product.

--- Dynamic pricing :

    Dynamic pricing is a non static pricing. Dynamic pricing is an efficient method for the market based on the supply and demand.

--- Penetration pricing :

 Penetration pricing is used by the large companies which is used to capture the market share by the setting product prices at the below market level so as to gain customers.

--- Doing a research for the price skimming helps the company to set up the accurate price for the product rather than readjusting the prices of the product later on based on the demand and the supply.

Consider the following reaction: 4Fe + 302 → 2Fe2O3. What mass of iron(III) oxide would
frutty [35]

Answer:

Mass = 357.7 g

Explanation:

Given data:

Mass of Fe =  250 g

Mass of oxygen = 120 g

Mass of iron(III) oxide produced = ?

Solution:

Chemical equation:

4Fe + 3O₂        →     2Fe₂O₃

Number of moles of Fe:

Number of moles = mass/molar mass

Number of moles = 250 g/ 55.8 g/mol

Number of moles = 4.48 mol

Number of moles of O₂ :

Number of moles = mass/molar mass

Number of moles = 120 g/ 32 g/mol

Number of moles = 3.75 mol

Now we will compare the moles of reactants with product.

        Fe          :          Fe₂O₃

        4            :             2

      4.48         :        2/4×4.48 = 2.24

        O₂          :          Fe₂O₃

        3            :             2

      3.75         :        2/3×3.75= 2.5

Less number of moles of Fe₂O₃ are produced by Fe thus it will act as limiting reactant.

Mass of Fe₂O₃:

Mass = number of moles × molar mass

Mass = 2.24 mol × 159.69 g/mol

Mass = 357.7 g

a chemistry teacher adds 50.0 ml of 1.50 m h2so4 solution to 200 ml of water. What is the concentration of the final solution?
nevsk [136]

Answer:0.300M

Explanation:1) Data:

a) Initial solution

M = 1.50M

V = 50.0 ml = 0.050 l

b) Solvent added = 200 ml = 0.200 l

2) Formula:

Molarity: M = moles of solute / volume of solution is liters

3) Solution:

a) initial solution:

Clearing moles from the molarity formula: moles = M × V

moles of H₂SO₄ = M × V = 1.5M × 0.050 l = 0.075 mol

b) final solution:

i) Volumen of solution = 0.050 l + 0.200l = 0.250l

ii) M = 0.075 mol / 0.250 l = 0.300M ← answeer
