Calculate the molar mass of B(NO3)3 ?​

Chemistry
1 answer:
Stella [2.4K]2 years ago
7 0

The molar mass of B(NO₃)₃ - Boron nitrate : 196.822 g/mol

<h3>Further explanation</h3>

In stochiometry therein includes  

<em>Relative atomic mass (Ar) and relative molecular mass / molar mass (M)  </em>

So the molar mass of a compound is given by the sum of the relative atomic mass of Ar  

M AxBy = (x.Ar A + y. Ar B)  

The molar mass of B(NO₃)₃ - Boron nitrate :

M B(NO₃)₃ = Ar B + 3. Ar N + 9.Ar O

M B(NO₃)₃ = 10.811 + 3. 14,0067 + 9. 15,999

M B(NO₃)₃ = 196.822 g/mol

What mass of magnesium oxide is produced when 60g of magnesium is burnt in air?
True [87]

Answer:

The chemical equation can be written as:

2Mg+O

2

→2MgO

48 g of Mg reacts with 32 g of O

2

.

Thus, 4.8 g of Mg reacts with 3.2 g of O

2

.

Now, 32 g of O

2

forms = 80 g of MgO.

3.2 g of O

2

produces =

32

80

×3.2 = 8 g of MgO.

Answer: a.Oxygen combines with carbon of simple sugar.

In cellular respiration, the presence of oxygen results in the break down of glucose molecule is broken down into carbon dioxide and water. The energy is required for this process that transforms the glucose in the form of ATP. The oxygen is required to produce ATP. Later on more energy is produced by the process of oxidative phosphorylation. ATP molecules transfers energy to the cells, which are the chief source of energy and also get used up in this process.

Write a balanced chemical equation for the reaction that occurs when titanium metal undergoes a combination reaction with O2(g).
arsen [322]

The balanced chemical equation for the reaction that occurs when titanium metal undergoes combination reaction with oxygen is;

Ti(s+ O_{2}(g) = TiO_{2}(s)

<h2>Further Explanation: </h2><h3>Chemical equations   </h3>
  • Chemical equations are equations showing reactions between reactants to form products. Chemical equations show the reactants or starting substances and products or substances formed during the reaction.
<h3>Law of conservation of mass   </h3>
  • The law of conservation requires that when writing chemical equations, the mass of the reactants should be equal; to the mass of the products.
  • This is done by making sure the number of atoms of each element involved in the chemical equation is equal on both sides of the equation.
  • To ensure the law of conservation in chemical equations is observed we balance chemical equations.
<h3>Balancing chemical equation: </h3>
  • Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products.
  • Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reactions.
  • For example; the equation;

Ti(s+ O_{2}(g) = TiO_{2}(s) is balanced as the number of titanium and oxygen atoms are equal on both sides of the equation.
