Answer: All of them are true
The Kj of heat that are needed to completely vaporize 1.30 moles of H2O if the heat of vaporization for water is 40.6 Kj/mole is calculated as below
Q(heat) = moles x heat of vaporization)
=1.30 mol x40.6 kj/mol= 52.78 Kj is needed
Answer: C. Electrons are lost.
Explanation:
- The oxidation reduction reaction is between oxidizing agent and reducing agent.
- The oxidizing agent gains electrons and reduction process occurs to it, while the reducing agent losses electrons and oxidation process occurs to it.
- oxidizing agent + ne → product <em>"reduction process, gain electrons"</em>
- reducing agent → product + ne<em> "oxidation process, loss electrons"</em>
- Thus, The right answer is: in the oxidation process, electrons are lost.
Answer:
7 chlorine atoms
Explanation:
K=2.8.8.1
Cl=2.8.7
pottasium will give chlorine its I valence electron to form ions as follows
K=(2.8.8)+
Cl=(2.8.8)-
I don’t know the author or what book/literary work this is, but could be how proteins are produced.
