Explanation:
Given equation of reaction:
Li + Br₂ → LiBr
In balancing any chemical equation, they must obey the law of conservation of matter. This law suggests that the number of moles of reactants and products must be the same in a chemical reaction.
This suggests that no amount of matter is lost during a chemical reaction.
The reaction above is a combination reaction in which two species combines to give a product.
To balance chemical reactions, we can simply inspect and assign the appropriate coefficient to the reactants and products. The coefficients should be whole numbers.
Also, the approach here would be mathematical where we would derive simple and solvable algebraic expressions to address the problem.
Assign alphabets a, b and c to the species;
aLi + bBr₂ → cLiBr
Conserving Li; a = c
Br; 2b = c
let b = 1;
c = 2
a = 2
The coefficients are 2, 1 and 2
The balanced equation is:
2Li + Br₂ → 2LiBr

Given that the metal is reactive, like magnesium is, the ions of the metal displace the hydrogen ions released by the acid and the metal ions combine with the acid's anions, forming a salt. The displaced hydrogen ions are released in the form of hydrogen gas. The reaction equation is as follows:
Acid + metal → salt + hydrogen gas
Answer:
The reason that that elements in the same 'group' have similar chemical properties is because they have the same number of valence electrons. ... Iron when reacting in chemical reactions loses electrons from its 4s orbital instead of its d orbital
Because there is a higher volume of heat in the iceberg. Heat enery is the amount of heat there is in a substance. it may be cold heat or warm heat
