Answer:
proposing a hypothesis.
Explanation: Therefore the last step in the scientific method is proposing a hypothesis or obtaining a conclusion.
Sulfuric acid is prepared industrially by means of the response of water with sulfur trioxide which in turn is made by way of a chemical combination of sulfur dioxide and oxygen both by way of the touch system or the chamber system.
H2SO4 (l) H2O (g) + SO3 (g).
The reaction is highly exothermic as an enormous amount of heat is liberated.
The usual approach is to dilute the sulfur trioxide in sulphuric acid. This produces oleum. SO3 (g) + H2SO4 → H2S2O7 (1) Oleum can be in addition diluted in water to acquire concentrated sulphuric acid.
An acid catalyst is added to protonate the carbonyl carbon. How does this catalyze the response, robust acid catalysts catalyze the hydrolysis and transesterification of esters which enables the mechanism with a view to boom the electrophilicity of the carbonyl carbon to assist protonate the carbonyl oxygen.

Answer:
B 1.87×10^-²
Explanation:
20.1797 g Neon = 1 mol
0.378 g Neon = y
(Cross multiply)
20.1797y= 0.378 x 1
(Make y the subject of the formula)
y = 0.878/ 20.1787
y = 0.0187317
y = 0.0187 approx
y = 1.87 x 10^-²
Answer:
Ca = 10,63
Explanation: Let's see, these are equations, now Look at ca and ca equates to all chemical equations= 10,63
