Answer:
H+ ----- Br-
H+ ----- Cl-
O₋₋ -----2H++
CH3 ----- O- ------ H+
Explanation:
Dipole moment occurs when there is bonding between a very strong electronegative element and hydrogen atom.
Electronegative elements are the element which attract electrons towards themselves, (that is they have strong affinity for electrons).
Generally, group 7 elements (Fluorine, Chlorine, Bromine, Iodine) of the periodic table are highly electronegative
Answer: 3597 kJ of heat
Explanation:
According to ideal gas equation:
P = pressure of gas = 5.00 atm
V = Volume of gas = 8.00 L
n = number of moles = ?
R = gas constant =
T =temperature =
As it is given :
1 mole of propane produces = 2220 kJ of heat
Thus 1.63 moles of propane produces = 
Thus 3597 kJ of heat is produced
Answer:
Yes it's balanced
Explanation:
on the left side, it contains
1 zn and 2 hydrogen and 2 chlorine
while on the right side it contains
1 zn 2 chlorine and 2 hydrogen
Neon = app. 20.1795 g/mol
<span>Bromine = app. 79.904 g/mol </span>
<span>-----> 79.904 g/mol / 20.1795 g/mol = 3.96 (Close to 4) </span>
<span>Using Moles In 1000 g </span>
<span>1000 g / 20.1795 g/mol = app. 49.555 mol of Ne </span>
<span>1000 g / 79.904 g/mol = app. 12.515 mol of Br </span>
<span>-----> 49.555 mol / 12.515 mol = 3.96 (Close to 4) </span>
<span>Using Avogadro's Number </span>
<span>49.555 mol x 6.022x10^23 atoms = app. 2.984x10^25 atoms of Ne </span>
<span>12.515 mol x 6.022x10^23 atoms = app. 7.537x10^24 atoms of Br </span>
<span>-----> 2.984x10^25 / 7.537x10^24 = 3.96 (Close to 4) </span>
<span>So no matter how you look at it or calculate it, the answer is always the same. </span>
<span>I hope it helps!</span>
