Answer:
Every homogeneous mixture is uniform in nature.
Explanation:
One of the most interesting facts about homogeneous mixtures is that, in a sense, there's no real distinction. The mixture is uniform in nature.
Conversely, at a large enough scale everything in the universe is homogeneous, because it becomes impossible to differentiate components.
magnesium + oxygen =magnesium oxide
magnesium oxide = magnesium
magnesium + oxygen magnesium + oxygen
Answer: magnesium + oxygen =magnesium oxide
Explanation: When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.
Mg (s) + O (g) → MgO (s)
In this equation, both magnesium and oxygen are present in its elemental state.
Magnesium is present in solid form and oxygen is present in gaseous form.
The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.
Answer: (B) Magnesium + oxygen =magnesium oxide
Explanation:
the true molar mass of the compound is 166.22 g/mol, what is its molecular
formula?
Answer:The empirical formula is KCO2
Explanation:
Answer:
Li2O+H2O---->(2)LiOH
Explanation:
you have to balance the equation and not all the blanks have to be filled all the time but if it makes it easier for you in the first 2 question marks you can put a 1 which isnt necessary but if ur a visual person it will help.
hope this helps im litterally learning the same thing as u lol
Answer:
1,1,2
Explanation:
this was correct for me, if it wasnt correct check if youre on the right question
Answer:
1.
Explanation:
Answer:
of would be required.
Explanation:
The quantity of solute in a solution of concentration and volume would be .
It is given that volume for the solution in this question. It is also given that the concentration of the solute in this solution is , which is the equivalent to .
Apply the equation to find the quantity of in this solution:
.
Multiply the quantity of in this solution with the formula mass of to find the corresponding mass:
.
Thus, this solution would contain of .
It would thus take of to prepare this solution.
Answer:
The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g
Explanation:
We do this by preparing the equation:
Mass = concentration (mol/L) x volume (L) x Molar mass
Mass = 1.0 M x 2.5 L x 40 g/mol
Mass = 100 g
