Precipitation reaction and double displacement reaction
Answer:
You can see in the above illustration of the periodic table that N is in Period 4, Group 5A, and p-block. Before reaching N, you will pass through the atomic orbitals 1s, 2s, and 2p. The electron configuration of N3- is N3-: 1s22s22p6 .

Answer:
0.13 J/g.°C.
Explanation:
- To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat absorbed by lead (Q = 29.0 J).
m is the mass of lead (m = 15.0 g).
c is the specific heat capacity of lead (c = ??? J/g.°C).
ΔT is the temperature difference (final T - initial T) (ΔT = 37 °C - 22 °C = 15.0 °C).
∵ Q = m.c.ΔT
<em>∴ c = Q/m.ΔT </em>= (29.0 J)/(15.0 g)(15.0 °C) = <em>01288 J/g.°C ≅ 0.13 J/g.°C.</em>
Answer:
A force involves an interaction between two or more objects, and it causes a push or pull between the objects. ... Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.
