Hello!
The general chemical equation for the neutralization of an acid HA with NaOH is the following:
HA(aq) + NaOH(aq) → NaA(aq) + H₂O(l)
For determining the concentration of the acid solution, we can use the equation shown below:
So, the concentration of the Acid is
0,36 MHave a nice day!
Answer:
1. All the possible energy transformations that occur with a dishwasher that uses electrical energy are heat energy because the dishwasher uses the electrical energy to heat the water, also electrical energy is transformed into kinetic energy and sound energy the reasoning behind this is that the parts moving inside the dishwasher is causing the sound.
2. Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.

Answer:
The the empirical formula for magnesium chloride based on this experiment will be
Explanation:
Given that,
Mass of Mg = 0.50 g
Mass of magnesium chloride found = 1.99 g
Let the formula of magnesium chloride be
We know that,
Molar mass of Mg= 24 g/mol
Molar mass of magnesium chloride = (24x+35.5y) g/mol
We need to calculate the moles of Mg
Using formula of moles
Put the value into the formula
We need to calculate the mole of magnesium chloride
Using formula of moles
Put the value into the formula
The reaction will be,
We need to calculate the value of x and y
Using number of moles of Mg in reactant and product
Moles of Mg atom in reactant=Moles of Mg atom in product
Hence, The the empirical formula for magnesium chloride based on this experiment will be
