Answer:
Rate of heat transfer will be 10.69 kw
Explanation:
We have given temperature
From standard table enthalpy of vaporization 2382.75 KJ/kg
Steam is coming out from turbine at rate of 16.154 kg/hour
We have to calculate the rate of heat transfer
Heat transfer is equal to
So rate of heat transfer
=
So rate of heat transfer will be 10.69 kw
Im not sure if this is physics or mathematics. but if 300 msec then per minute this will equal to 300 X 60 sec =18000 m per minute
Answer: A. need the same number of electrons to fill their valence shells
B. have the same number of valence electrons
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
Example: Flourine, chlorine and bromine are elements which belong to Group 17. They have 9, 17 and 35 electrons respectively and contain 7 valence electrons each and need one electron to complete their octet.
The chemical reactivity of elements is governed by the valence electrons present in the element.
