Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged.
Answer:
I´m willing but not able due to the fact that school is piling in the work. Sorry.
Answer:
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formula. (i) It must refer to an actual chemical reaction. (ii) It should be molecular. For example, H, O, N should be written as H2, O2, N2. (iii) It should be balanced and conform to the law of conservation of matter.A chemical equation conveys both qualitative and quantitative information. Qualitatively, a chemical equation tells the names of the various reactants and the products.
Answer:
The empirical formula would be AlCl₃
Explanation:
The ratio of number of moles of each reacted specie can help to determine the empirical formula
moles of Al
moles of Cl
Ratio of moles
Empirical formula
Calculation shows that the number of moles of chlorine are three times higher than aluminium, hence empirical formula would be AlCl₃
The given question is incomplete, here is a complete question.
At 400 K, this Reaction has
What Is at 400 K for the following reaction?
(A) 8.2 x 10⁻⁴
(B) 2.9 x 10⁻²
(C) 6.7 x 10⁻⁷
(D) 1.6 x 10⁻⁷
Answer : The correct option is, (C)
Explanation :
The given chemical equation follows:
The equilibrium constant for the above equation, .
We need to calculate the equilibrium constant for the following equation of above chemical equation, which is:
,
The equilibrium constant for the doubled reaction will be the square of the initial reaction.
Or, we can say that
If the equation is multiplied by a factor of '2', the equilibrium constant will be the square of the equilibrium constant of initial reaction.
The value of equilibrium constant for the following reaction is:
Hence, the value of equilibrium constant for the following reaction is,
