What is a correctly written chemical equation?
A correctly written chemical equation should show the reactants on the left side and the products on the right side, separated by an arrow. The equation should be balanced, meaning that the number of each type of atom is the same on both sides of the equation. The chemical formulas of the substances involved should be correctly written with the appropriate subscripts and coefficients.
What is written in front of the formula used to balance chemical equations?
The reactants are written on the left side of the equation, while the products are written on the right side. The equation is balanced by adjusting the coefficients in front of the chemical formulas so that the number of atoms for each element is the same on both sides.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
How does a correctly written chemical equation show that atoms are not lost in a chemical equation?
By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
When is it said to be a unbalanced equation?
An unbalanced chemical equation is when the number of atoms of each element in the reactants is not equal to the number of atoms of the same element in the products. This can be corrected by adjusting the coefficients in front of the chemical formulas to balance the equation.
What is understood if no coefficient is written before a formula in a chemical equation?
If no coefficient is written before a chemical formula in a reaction, it is undertood to mean 'ONE Molar Ratio'. e.g. 2NaOH + H2SO4 = Na2SO4 + 2H2O Two(2) molar ratios of (NaOH) One(1) molar ratio of (H2SO4) produces One(1) molar ratio of (Na2SO4) Two(2) molar ratios of (H2O ; Water).

A number written to the left of a chemical symbol or formula is called?
The MOLAR RATIO or Coefficient. Do NOT confuse with numbers AFTER the chemical symbols. e.g. 2NaOH + H2SO4 = Na2SO4 + 2H2O The Molar Ratios (Coefficients) are in order from left to right ' 2:1 :: 1:2 '. In Na2SO4 the numbers '2' refers to TWO sodium atoms And '4' refers to FOUR oxygen atoms. In '2H2O'. The left hand '2' refers to TWO molar ratios. The '2' to the right of 'H' (Hydrogen) refers to each molecule having two (2) hydrogen atoms. NB When no number is shown, read it as '1'(one). This applies to molar ratios and to atom numbers in a molecule. e.g. NaOH ; No numbers, so there is only ONE of each atom. Similarly, H2O means only ONE(1) atom of oxygen, in the molecule.
A number placed in front of a chemical formula in a chemical equation is called?
In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.
How does a correctly written chemical equation show that atoms are not lost in a chemical equation?
By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
What is the difference between a subscript and coefficiant?
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
When is it said to be a unbalanced equation?
An unbalanced chemical equation is when the number of atoms of each element in the reactants is not equal to the number of atoms of the same element in the products. This can be corrected by adjusting the coefficients in front of the chemical formulas to balance the equation.
A number placed in front of a chemial formula in a chemical equation is called?
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
What is ment by the term coefficient in relation to a chemical reaction?
A coefficient is a number written in front of a chemical formula when balancing a chemical equation. The coefficient can represent the number of atoms, molecules, formula units, or moles of the substance.
A number in front of a chemical formula in a chemical equation is called a?
coefficent
