Which of the following popular sayings is an example of a true scientific theory?
Rom4ik [11]
The carrot myth was invented by the English Airforce to hide their radar system during WW(1 or 2, I'm not sure). Dropped food doesn't matter because dust and bacteria the food touches are on it the moment it hits the ground. Touching toads doesn't give warts, however the poison he secretes from its skin (a toad is poisonous, not venomous) can irritate. So it must the warm milk.

Explain why the following chemical equation represents a Lewis acid-base reaction. H+ + NH3 —>NH4+
lozanna [386]

Answer:

Due to an electron-pair acceptor and donor.

Explanations:

<em><u>Lewis acid</u></em> can be defined as an electron-pair acceptor. An example is Hydrogen ion(H+). This is because it is a proton and it distributes positive charge which means that it accepts electrons(negative charge).

<em><u>Lewis base</u></em> can be defined as an electron-pair donor. This is because it donates electrons to be accepted by the proton. An example is ammonia(NH3).

What is true regarding the calculation in redox titration? group of answer choices moles of the oxidant equal mole of the reduct
SVEN [57.7K]

Moles of titrant are lost in the calculation in redox titration.

"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.

The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.

Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. In the realm of analytical chemistry, titration is a crucial technique.
