The balanced chemical equation is given as:
2CH3CH2OH(l) → CH3CH2OCH2CH3(l) + H2O(l)
We are given the yield of CH3CH2OCH2CH3 and the amount of ethanol to be used for the reaction. These values will be the starting point for the calculations.
Theoretical amount of product produced:
329 g CH3CH2OH ( 1 mol / 46.07 g ) ( 1 mol CH3CH2OCH2CH3 / 2 mol CH3CH2OH ) (74.12 g / mol ) = 264.66 g CH3CH2OCH2CH3
% yield = .775 = actual yield / 264.66
actual yield = 205.11 g CH3CH2OCH2CH3
Answer:
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.

Answer:
1)Pb(NO3)(aq) + MgSO4(aq)------> Mg(NO3)2(aq) + PbSO4(s)
2)Mn(NO3)2(aq) + 2KOH(aq) ----->Mn(OH)2(s) + 2KNO3(aq)
3)Zn(s) + 2H^2+(aq)----->Zn^2+(aq) + H2(g)
4) Cu(s) + 2Ag^+(aq) ---->Cu^2+(aq) + 2Ag(s)
Explanation:
A double replacement reaction is one in which ions exchange partners.
We can see that the ions in the reactants exchanged their partners in the products. Solid lead II sulphate was precipitated.
Reaction 2 is a single replacement reaction. Solid manganese hydroxide is formed.
Reactions 3 and 4 are redox processes as shown in the respective equations.
Answer: Copper sulfate solution
CUSO4)
Explanation: cashing ion redox Copper sulfate solution. Reaction of zinc metal in copper sulfate solution. The process that occurs in this redox reaction is shown below as two separate half-reactions, which can then be combined into the full redox reaction.
