The Urease test recognizes living beings that are equipped for hydrolyzing urea to deliver smelling salts and carbon dioxide. It is utilized to recognize urease positive Proteeas from other Enterobacteriaceae.
It is a huge group of microscopic organisms, which are Gram-negative and bar mold. They are chemo-organotrophic and can develop in the nearness or nonappearance of air. There are numerous genera, found as parasites and pathogens in an extensive variety of life forms from plants to people.
The liters in 3.25 g of ammonia 4.28 L
<u><em>calculation</em></u>
Step 1: find moles of ammonia
moles = mass÷ molar mass
From periodic table the molar mass of ammonia (NH₃) = 14 +(1×3 ) = 17 g/mol
3.25 g÷ 17 g/mol = 0.191 moles
Step 2: find the number of liters of ammonia
that is at STP 1 moles = 22.4 L
0.191 moles = ? L
<em>by cross multiplication</em>
={( 0.191 moles ×22.4 L) / 1 mole} = 4.28 L
Answer:
A. Strong Acid Strong Base
D. ... 100%
Explanation:
The reaction of hydrobromic acid and sodium cyanide is a strong acid-strong base reaction. In solution, sodium cyanide functions as a strong base and reacts violently with strong acids. For strong acid- strong base reaction, the extent of reaction is usually 100%.
The molecular reaction equation is
NaCN(aq) + HBr(aq) ---------> NaBr(aq) + HCN(aq)
Ionically:
H3O+(aq) + CN- (aq) ----------> HCN(aq) +H2O (l)
HCN(aq) is a weak acid.
Elements are used to create bonds and are classified as particles.
Answer: It is less than 8 N
