Answer:
6 Li(s) + N₂(g) → 2 Li₃N(s)
Explanation:
Solid lithium metal and diatomic nitrogen gas react spontaneously to form a solid product (lithium nitride). The chemical equation is:
Li(s) + N₂(g) → Li₃N(s)
Since the atomicities in the product are odd, the easiest way to balance the equation is by first multiplying it by 2.
Li(s) + N₂(g) → 2 Li₃N(s)
The final (balanced) equation is:
6 Li(s) + N₂(g) → 2 Li₃N(s)
<span>pH = pKa + log ([base]/[acid]) = -log (3.5 x 10^-4) + log (0.040/.020) = 3.46 - 0.30 = 3.16</span>
Explanation:
The kinetic energy of an object is given by :
1. Mass, m = 5 kg
Speed, v = 2 m/s
2. Mass, m = 71 kg
Speed, v = 1 m/s
3. Mass, m = 71 kg
Speed, v = 5 m/s
4. Mass, m = 1816 kg
Speed, v = 25 m/s
Ironing clothes is Conduction.
<h3>What is Conduction? </h3>
Conduction is one of the means of Heat transfer ,others includes
Conduction is the transfer of heat energy from one object to another object from particles in a hotter object to particles in a cooler object, For Example: Ironing clothes is conduction.
This is because The heat from the iron which transfers to the clothes is conduction.
