0.1045M is the concentration of the original sulfuric acid solution
Explanation:
Titration is done to know the volume or concentration of unknown electrolyte.
Data given:
volume of acid = 50 ml
molarity of acid =?
volume of base NaOH = 34.62 ml
molarity of the base = 0.1510
For titration the formula used is,
Macid x Vacid = Mbase x V base
Putting the values in above equation:
M acid x 50 = 34.62 x 0.1510
Macid = 
= 0.1045 M is the molarity of sulphuric acid solution used in neutralization of 0.1510 M base solution.
Answer:
K2X
Explanation:
Valency can be defined as the combining power of an element. It is the valency that dictates the value an element will have when writing a chemical formula for its compound.
MgX is a compound of magnesium and an element X. The valency of magnesium in most of its compound is +2. Now for the 2 to have been absent in the chemical formula, this shows that the element X itself have a valency if -2 for the valencies of both to have canceled out.
Now considering the element potassium, it is an alkaline metal belonging to group 1 of the periodic table. Hence, it is expected that it has a valency of +1
Forming a compound with element X means there would be an exchange of valencies between the two. We have established that x has a valency of -2. The formula of the compound thus formed by exchanging the valencies of both element would be K2X
Answer:
The physical and chemical change that occurs in the aquaponics are given below.
Explanation:
The plants and animals grow in size and decrease the mass of plant due to eating by the fishes is a physical changes which occurs in aquaponics. The sunlight has a heat energy which is absorb by the plants present in aquaponics which is a type of endothermic reaction. In aquaponics, the ammonia present in water is converted into nitrates which is used by the plants as a nutrients. When the mass is converted into energy, it increases the temperature of the ecosystem and also the earth surface. For example, if a wood is burn, it change into heat energy which increases the temperature and cause the global warming on the earth surface.
Sorry, Cant really tell how to differentiate the students and trial times
