First, find length of AB, using coordinates of the points A and B.
A(1,4) and B(4,8)
|AB|=√((y2-y1)² +(x2-x1)²) =√((8-4)²+(4-1)²)=√(16+9)=√25=5
When dilating with scale factor 4,
the length of |A'B'|=4*|AB|=4*5=20
Answer:
a. The resonance effect of the hydroxyl group stabilizes the anionic intermediate
Explanation:
The resonance effect stabilizes the the charge through the delocalization of the pi bonds. The resonance stabilization mainly occurs in the conjugated pi systems.
For example, phenol forms a strong hydrogen bonds than the nonaromatic alcohols as the dipole present in the hydroxyl group is being stabilized by the presence of the aromatic ring of phenol.
Thus the resonance effect of the hydroxyl group stabilizes the anionic intermediate.
Molar mass NH3 = 17.031 g/mol
1 mole NH3 -------------- 17.031 g
?? moles NH3 ---------- 346 g
346 x 1 / 17.031
=> 20.31 moles of NH3
Answer:
A) oxidizing agent is SO2
B) NaClO is the oxidizing agent
Explanation:
A) This is a redox reaction in which oxidation and reduction occur simultaneously.
Thus, in 2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s);
H2S is reduced as follows;
H2S → S + 2H+ + 2e−
We can see that SO2 has been reduced while H2S gets oxidized since it has changed state from - 2 to 0 . Thus sulphur dioxide is the oxidizing agent.
B) SO2(g) + H2O(l) + NaClO(aq) -> NaCl(aq) + H2SO4(aq)
In this, SO2 undergoes oxidation and NaClO is the oxidizing agent
The ionic compound that results from the reaction between an acid and a base is called salt
Ions are present in ionic compounds, which are held together by the attraction interactions between the ions with opposing charges. One of the most well-known ionic compounds is table salt or sodium chloride. Molecular compounds are made up of separate molecules that are connected by sharing electrons (covalent bonding).
The simplest way to determine whether a chemical compound is an ionic compound is to see if it only contains two elements, one of which can be a metal (belonging to either of groups 1, 2, or 3), and the other of which can be a non-metal (from group 5, 6 or 7). An illustration of an ionic compound is table salt. The compound sodium chloride, or NaCl, is created when sodium and chlorine ions combine.
