Answer: Water
Explanation:
Chemically speaking, a solution has two components: solute and solvent.
The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent.
</u>
The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used solvent water.
This means that in a solution there is usually more solvent than solute.
So, in the case of the hydrogen peroxide solution, since the proportion is to , the hydrogen peroxide is the solute and water is the solvent.
Answer: Yes , in , two electrons from magnesium are transferred to chlorine atoms.
Explanation:
Ionic compound is formed by the transfer of electrons. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
For example : For formation of
Electronic configuration of magnesium:
Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.
Electronic configuration of chlorine:
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
In Magnesium chloride two electrons from magnesium metal gets transferred to two chlorine atoms and thus is formed.
Answer:
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
Answer:
n = 0.413moles (3 sig-figs).
Explanation:
From definition of molarity, solve for moles and substitute given data.
Molarity(M) = Moles Solute(n)/Volume of Solution in Liters(V)
M = n/V => n = M·V => 0.330moles/Liter x 1.25Liters = 0.4125moles ≅ 0.413moles (3 sig-figs).
Answer: produces hydronium ions (H 3O +) as follows: Chemists often simply call this the hydrogen ion, and use the notation H + (aq) as shorthand for the H 3O + (aq) ion.
