Answer:
umm it does not show what elements but I think its C. number of protons
Answer: 0.0345 sec
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![Rate=k[H_3PO_4]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BH_3PO_4%5D%5E2)
k= rate constant = 
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
for completion of 20 % of reaction



The time taken for the concentration of
to decrease to 20% to its natural value is 0.0345 sec
Answer:
Check the explanation
Explanation:
functional group found in the major organic product = alpha -beta unsaturated ketone
Reaction used to form this functional group = Michael condensation reaction
Also other reactions are - Aldol condensation , Robinson annulation reaction.
Kindly check the attached image below to see the step by step solution to the question above.
B. Aluminum, Al3+, aluminum ion is correct
Chloride would be negative, Iron has Fe for the symbol, potassium is K....
Answer:
There are a number of possibilities for the answer to this question, so I will address a few only:
Explanation:
1. Many ionic substances will dissolve completely in water to form an aqueous solution of cations and anions; this solution will conduct electricity.
2. The substance will have a slightly lower melting point than a mid-level covalent network solid.
3. The substance will certainly not conduct electricity as a solid.
