Yes as there is advertisements for this as a alternative to glue.<span />
Definitely, the more you research into something the more information on it you’ll get, they could very well realize that with the new information their old faces were incorrect
The procedure, which can be used to determine more accurately the concentration of the unknown acid is TO BACK-TITRATE WITH ADDITIONAL HYDROCHLORIC ACID TO NEUTRALIZE THE ADDITIONAL SODIUM HYDROXIDE THAT WAS ADDED.
Monoprotic acids are acids that can donate only one proton per each molecule and they have only one equivalence point. Examples of monoprotic acids are HCI, HNO3 and CH3COOH.
The back titration method is typically used when one needs to determine the concentration of an analyte provided there is a known molar concentration of excess reactants.
From the information given in the question above, we are told that excess NaOH was added. To correct this mistake, the right thing to do is to use additional HCl to carry out back titration, taking note of the quantity of acid that will be needed to neutralize the excess NaOH.
The answer is (2). The question only ask the production of acid reacts with base. The acid has H+ ion and base has OH- ion. When they react, the production will always contain H2O.
Answer : The heat created by the food is, 3971 J
Explanation :
Formula used:
where,
q = heat produced = ?
m = mass of water = 100 g
c = specific heat capacity of water = 
= change in temperature = 
Now put all the given values in the above formula, we get:
Therefore, the heat created by the food is, 3971 J
