Answer:
Oxygen is more electronegative.
Explanation:
Electronegativity:
Electronegativity of an atom is its tendency to attract the electron to wards it self.
Br = 2.98
O = 3.44
Oxygen is more electronegative than bromine thus it attract electron more strongly towards itself as compared to bromine.
when an more electronegative atom combine with less electroneagtive atom partial charges are created upon them. e.g
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
Answer:
New volume, V2 = 15mL
Explanation:
Given the following data;
Initial volume, V1 = 30mL
Initial pressure, P1 = 4atm
New pressure, P2 = 8atm
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
V2 = 15mL
<em>Therefore, the new volume is 15 mL. </em>
D. Itd be 4+. Hope it helps
Answer:
The answer to your question is: Molarity = 0.30
Explanation:
Data
V1 = 76 ml
C1 = 1.4 M
V2 = 208 ml
V3 = 104 ml
V water = 153 ml
Process
C1V1 = C2V2
C2 = C1V1/ V2
C2 = (1.4)(76) / 208
C2 = 0.51 M
Molarity = moles / volume
moles = Molarity x volume
moles = 0.51 x 0.208
moles = 0.11 Final volume = 0.208 + 0.153
Molarity = 0.11 / 0.361
Molarity = 0.30
