Transferring or sharing electrons between atoms forms a covalent bond.<span> Covalent
bonding is when atoms share electrons. It is a chemical bond that involves the
sharing of electron pairs. These pairs are called bonding pairs. Examples of
compounds that has covalent bonds are CO2, organic compounds, lipids and
proteins.</span>
The answer is affirmative because <span>dilutions give you a weaker Molarity
Plase see this in the dilution formula that follows:
C1V1 = C2V2
(0.50M) (10.00ml) = (C2) (100ml)
C2 = 0.050 M
10X's weaker
</span>Hope this helps a lot
An open system is
when there is a transfer of energy and matter with its surroundings.
A closed system is
where there is a transfer of energy, may it be heat or work, but not matter
with its surroundings.
An isolated system
is where there is no transfer of energy or matter with its surroundings.
<u>Given information:</u>
A solution with a high H+ ion concentration
<u>To determine:</u>
The nature of pH of such a solution
<u>Explanation:</u>
pH is a measure of the H+ ion concentration in a given solution. Lower the pH higher will be the H+ concentration and the solution is termed acidic. In contrast, if the pH is higher the H+ concentration will be lower and the solution is basic.
Mathematically,
pH = -log[H+]
[H+] = 
pH = 2; [H+] = 10⁻²M
pH = 7; [H+] = 10⁻⁷M
pH = 13; [H+] = 10⁻¹³M
pH = 14; [H+] = 10⁻¹⁴M
Ans: (a)
Thus, the highest concentration of H+ ions is for a solution of pH = 2
1)number mole in
50.8 g Zn *(1 mol Zn/65.4g)=0.777 mol Zn
2)number mole in
16.0 g P*(1 mol P/31.0 g)= 0.516 mol P
3)number mole in
33.2 g O*(1 mol O/16.0 g) = 2.075 mol O
0.777 mol Zn : 0.516 mol P : 2.075 mol O =
= (0.777 mol Zn/0.516) : (0.516 mol P/0.516) : (2.075 mol O/0.516)=
=1.5 mol Zn : 1 mol P : 4 mol O=3 Zn : 2 P : 8O
Zn3P2O8
or
the same is Zn3(PO4)2
