You should have given us a table, but I think my table shouldn't be too different.
Let's put oxidation numbers first.
You would have to know that Mg(s) is a reducing agent and Br2(l) is an oxidizing agent. But it is pretty common knowledge that the halogens will tend to take the electrons and alkali and alkaline earth metals will tend to give up electrons.
Mg is oxidized because it gives up electrons; Br2(l) is reduced because it gains electrons. Since the reaction conforms to what we would expect to <em>naturally</em> (thermodynamically favored) occur, it can take place given that the activation energy is supplied.
Answer:Radium
Explanation:
The nuclear reaction involving two alpha emissions of 234 U is shown in the diagram. This leads to the formation of a 226Ra nucleus.
Answer:
The volume of 6 M NaOH is 5.5 ml
Explanation:
The equation of reaction is
C₃H₅(C₁₇H₃₅COO)₃+3 NaOH → C₃H₅(OH)₃+3 C₁₇H₃₅COONa
The molar mass of triglyceride M is 890 g/mole, so in 10.0 g of its are
From the equation of reaction one mole of triglyceride reacts with three moles of NaOH.
So,
the quantity moles of NaOH which actually needed to react is:
0.011 x 3=0.033 moles.
These quantity moles of NaOH are consist in
∴The volume of 6 M NaOH is 5.5 ml
