Why is strontium more reactive than calcium but less reactive than rubidium?
1 answer:
Sr is below Ca and to the right of Rb in the Periodic Table (see the attached image).
Reactivity increases from <em>top to bottom of a Group</em>. Sr is below Ca, so it is <em>more reactive</em> than Ca.
Reactivity decreases from <em>left to right in a Period</em>. Sr is to the right of Rb, so it is <em>less reactive</em> than Rb.

Answer:
The inner diameter of the steam tube is 0.1185 m.
Explanation:
m = mass flow rate
= density of the liquid
V=specific volume =
v = velocity of the liquid
A = area of cross-section
Diameter of the cross-section = d = 2r
Given: m = 18 kg/s, v = 60 m/s,A=?,
Area of the inner cross section =
d = 0.1185 m
The inner diameter of the steam tube is 0.1185 m.
