Lithium has charge of +1 and bromide has charge of - 1. So they combine to form the compound lithium bromide which is expressed as LiBr.
<h3><u>Explanation:</u></h3>
Lithium is an alkali metal placed in group 1 or periodic table. It has a valency of 1 which is achieved as lithium loses an electron to achieve a charge of +1.
Bromine is a halogen which is placed in group 17 of periodic table. It has a valency of 1 which is achieved as bromine looses an election to achieve a charge of - 1.
Lithium is the cation and bromide is the anion. So lithium is written in front and bromine following the cation. And as both of their valencies are 1, so they form the compound LiBr.
Answer:
19,700 Joules
Explanation:
Quantity of heat (Q) = mc(T2-T1)
m (mass of ethanol) = 183g
c (specific heat capacity of ethanol) = 2.44J/g°C
T2 (boiling temperature of ethanol) = 78°C
T1 (initial temperature of ethanol) = 33.9°C
Q = 183×2.44(78 - 33.9) = 183×2.44×44.1 = 19691.532 = 19,700 Joules (to three significant digits)
