The correct answer among the choices given is option A. Hydrochloric acid is a much stronger acid than sulfuric acid given that the concentration both is equal. This can be proved by the pKa of these acids. Hydrochloric acid has a pKa of -6 while the pKa of sulfuric acid is -3. The lower the value of the pKa, the stronger the acidity of the substance.
Answer:
18
Explanation:
Sabemos que la fórmula química del agua es H2O.
Usando la información que; H = 1, O = 16, podemos calcular la masa molar del agua de la siguiente manera
[2 (1) + 16] = 18
Por tanto, la masa molar del agua es 18
Answer:
Balanced equation is related to the law of conservation of mass as it states that mass can neither be created nor be destroyed in a chemical reaction so the total no. of atoms in a reaction should remain same. in a balanced chemical equation also total no. of atoms of each elements remain same.
Answer:
<h3>The answer is 8.98 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of cube = 150 g
volume = 16.7 cm³
We have
We have the final answer as
<h3>8.98 g/cm³</h3>
