A balanced chemical equation occurs when
the number of the atoms involved in the reactants side is equal to the number of atoms in the products side
. In this chemical reaction, nitrogen (N2) reacts with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.
Which is a balanced chemical equation?
A balanced equation is an
equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products
. In other words, the mass and the charge are balanced on both sides of the reaction.
What is a balanced chemical equation give example?
Balanced chemical equation : A chemical equation in which the number of atoms of different elements on the reactants side (left side) are same as those on product side (right side) is called is balanced chemical equation. Eg :
2Cu+O2→2CuO
.
What is balanced chemical equation class 10?
4. Balanced Chemical Equation: A balanced chemical equation has
number atoms of each element equal on both left and right sides of the reaction
. … To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products.
Which equation is balanced 2Na Cl2?
The balanced equation is
2Na(s)+Cl2(g) → 2NaCl(s)
.
What is a balanced chemical equation class 11?
Answer. 123.3k+ views. Hint: Balanced chemical equations are those
in which the number of atoms on the reactant side is equal to the number of atoms on the product side
. The balancing of the chemical equation is based on the principle of “Law of conservation of energy”.
What is unbalanced chemical equation called?
An unbalanced chemical equation is called
a skeletal chemical equation
. Skeleton equations are the equations in which there is the only chemical formula of reactants and products are present. … For example- Mg + O
2
→ MgO, it is a skeleton equation.
What is a balanced and unbalanced equation?
A balanced chemical equation
has an equal numbers of atoms of different elements in the side of reactants and products
. An unbalanced chemical equation has an unequal number of atoms of one or more elements in the reaction.
Is 2Na Cl2 2NaCl balanced?
The equation
2Na+Cl->2NaCl is balanced
therefore, it is an example of the law of conservation of mass.
What is balanced chemical equation Why should chemical equation be balanced class 10?
A chemical equation should always be balanced because
the law of conservation of mass states that matter can neither be created nor destroyed so in a chemical equation the total mass of reactants must be equal to the mass of products formed
i.e. the total number of atoms of each element should be equal on both the …
What is skeletal chemical equation?
A skeletal chemical equation is
a representation of a chemical reaction using chemical formulae of reactants and products
. In the skeletal chemical equation, the mass no of elements on the reactant side is not equal to the mass no of elements on the product side.
What are balanced and unbalanced chemical equation give one example of each?
Unbalanced chemical equations possess different numbers of atoms of distinct elements in reactants as well as products. 2. … Examples of balanced chemical equation are listed below:
N2+3H2→2NH3C+CO2→2CO
Here in each case, the number of atoms of elements are the same on both sides.
Is it a balanced chemical equation yes or no?
Count the number of each type of atom in each type of molecule. Fill in the total number of atoms present for each type of molecule. … If each side of the equation has the same number of atoms of a given element, that element is balanced.
If all elements are balanced
, the equation is balanced.
What is the balanced equation of N2 H2?
o The new chemical equation is
N2 +H2 →2 NH3
Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens.
Is 2 h2o2 → 2 h2o o2 balanced?
Explanation: This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen. Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so
it is balanced
.
What type of reaction is 2Na Cl2 → 2NaCl?
The reaction 2Na + Cl2 = 2NaCl is an example of
Combination reaction
. Decomposition reaction will occur when one reactant breaks down into two or more products, e.g. AB => A + B. In Combination Reaction, two or more elements/compounds combine to form a single compound, e.g. A + B => AB.
What is the product of 2Na Cl2 → 2NaCl?
2Na (s) + Cl
2
(g) 2NaCl (s)
This can be understood by saying that two sodium atoms combine with one diatomic chlorine molecule to form two ionic units of
sodium chloride
.
Is this balanced AL O2 2Al2O3?
We will take the given equation: Al + O2 –> Al2O3. We can see that this
is not balanced
– there is 1 aluminum on the reactant side and 2 on the product side, and there are 2 oxygens on the reactant side and 3 on the product side. How will we balance it? … Finally we have a balanced equation: 4Al + 3O2 –> 2Al2O3 .
What is the balanced equation for the combustion of hexane?
The balanced chemical equation for the combustion of hexane is: 2C6H14(g)+19O2(g)→12CO2(g)+14H2O(g) 2 C 6 H 14 ( g ) + 19 O 2 ( g ) → 12 C O 2 ( g ) + 14 H 2 O ( g ) .
Is hydrogen H2 or H?
Hydrogen has a molar mass of 1 and it’s molecular formula is H2. Hydrogen,
H
, is the lightest element with the atomic number 1. It is a colorless, odorless, tasteless, and highly flammable gas with the molecular formula H2.
Is 2hgo 2hg O2 balanced?
O is a balanced element
because there is the same number of atoms of O in each side of the equation. All elements have the same number of atoms in each side of the equation, which means that the law of conservation of mass is satisfied and the chemical equation is balanced.
