C(Molarity) = n of solute/V of solution (mol/L)
glucose(C6H12O6) = 180g/mol
glucose 35g = 35g/(180g/mol) = 0.1944mol
We need density of solution here, and I assume it as density of phenol, 1.07g/mL. (I don't know why the question doesn't contain it)
phenol 0.16kg = 0.16kg/(1.07kg/L) = 0.1495L
0.1944mol/0.1495L = 1.300M(mol/L)
HCl04 is a strong acid solution. So, in theory everything dissociates.
pH= -log(0.000081)= 4.09
The answer is rings, I know this because i took a test about it and I got it right
Answer:
It is an example of Exothermic reaction.
Explanation:
It leads to release of HEAT as can be seen water is given in gaseous form.
This question is providing us with the chemical formula of a compound whose name in IUPAC convention is strontium hydroxide heptahydrate according to the following.
<h3>IUPAC nomenclature in hydrates</h3>
In chemistry, the IUPAC allows us to assign specific names for all the chemicals in the world, in order for them to be recognized all around the world and avoid common names which differ from region to region.
Thus, for the compound we are given, we see the presence of a cationic strontium ion and an anionic hydroxide ion, both accompanied by seven molecules of water, which makes it a hydrate.
In such a way, its IUPAC name will be strontium hydroxide heptahydrate, according to the both of the ions and the number of water molecules into it.
