Answer:
Explanation:
Amount HCl = 0.455mole
Molar mass = 1 + 35.5 = 36.5g/mol
Amount = mass/molar mass
:- mass = Amount × Molar mass
Mass = 16.97g
Answer:
See explanation
Explanation:
We know that water begins to expand at 4°C. This is generally referred to as the anomalous behavior of water.
The implication of this is that ice has a greater volume than water. Thus ice is less dense than liquid water.
n-butyl alcohol has much less density than water. This accounts for the fact that water upon freezing breaks the bottle while n butyl alcholol leads to a container with concave walls.
Hence the density of ice is much higher than the density of n butyl alcohol.
Answer:
Option-A is the correct answer
Explanation:
Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺
While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.
