Covelant molecules are formed d
Explanation:
when hot copper metal reacts with chlorine gas it forms CuCl2 which is yellow in colour.
non metal carbon burns in Oxygen gas they form non metal oxide.
Answer: option b. 1-chloro-4,4-dimethyl-2-pentene
Explanation: the numbering is done from the side that gives the double bond the lowest low count
D: 3, 2, 3, 1 The Pb3(PO4) comes from having 3 Pb and 2 H3PO4. The H2 comes from the 2H3PO4
Given,
Molality = .5M
We know, Kf = 1.86
Now,
Δ T = M x Kf
= 1.86 * 0.5
= 0.93 °C
Now,
Freezing point = Initial freezing point - Δ T
= 0°C - 0.93°C
= -0.93°C
So, the answer is A
