Answer: Option (4) is the correct answer.
Explanation:
According to Bronsted and Lowry, acids are the species which can donate hydrogen or ions.
Whereas bases are the species which can accept hydrogen or ions.
Thus, we can conclude that the statement acids are donors, and bases are acceptors describes an alternate theory of acids and bases.
Answer:
Explanation:
The volume of KBr required can be found by using the formula;
c is the concentration in M , mol/dm³ or mol/L
v is the volume in L or dm³
m is the mass in grams
M is the molar mass in g/mol
From the question;
m = 25.5 g
c = 0.716
Molar mass (M) of KBr = 39 + 79.9 = 118.9 g/mol
metamorphic
extrusive
sedimentary
igneous
Answer:
granoblastic metamorphic rock
Explanation:
a strong acid and a weak acid.
a strong base and a weak base.
an acid and water.
The right answer is A (strong acid with strong base).
The reaction of an acid with a base to produce salt and water alone is called a neutralization reaction.
A salt is a compound formed following a replacement of the hydrogen ions (H +) of an acid with a basic radical during a reaction.
A normal salt is formed by the complete replacement of the H + of an acid (example Na2CO3).
while an acidic salt is formed by the incomplete replacement of the H + of an acid (eg NaHCO3).
In a balanced chemical equation, the coefficients in front of the formulae can be used to determine the mole ratio. The mole ratio between NaOH and Al (OH) 1:1.
The ratio of the mole quantities of just about any two compounds present inside a chemical reaction is known as the mole ratio. In many chemical situations, mole ratios are employed as conversion factors among products and reactants.
In a balanced chemical equation, the coefficients in front of the formulae can be used to determine the mole ratio. A reaction's product yield may be predicted using mole ratios, as can the quantity of reactant required to produce a specific amount of result.
Al(OH) + NaOH →NaAlO + 2 HO
mole ratio between NaOH and Al (OH) 1:1
Therefore, the mole ratio between NaOH and Al (OH) 1:1.
