Answer:
2.4 ×10^24 molecules of the herbicide.
Explanation:
We must first obtain the molar mass of the compound as follows;
C3H8NO5P= [3(12) + 8(1) + 14 +5(16) +31] = [36 + 8 + 14 + 80 + 31]= 169 gmol-1
We know that one mole of a compound contains the Avogadro's number of molecules.
Hence;
169 g of the herbicide contains 6.02×10^23 molecules
Therefore 669.1 g of the herbicide contains 669.1 × 6.02×10^23/ 169 = 2.4 ×10^24 molecules of the herbicide.
Answer:
d = 70.5 mm
Explanation:
given,
length of pipe = 305 m
discharge rate = 150 gal/min
pipe diameter = ?
1 gal/min = 6.30902 × 10⁻⁵ m³/s
150 gal/min = 150 × 6.30902 × 10⁻⁵ m³/s
= 9.46 × 10⁻³ m³/s
Q = A V
f = 0.048 from moody chart using P/D = 0.00015
d = 70.5 mm
Diameter of the pipe is equal to 70.5 mm
Answer:
a, b
Explanation:
Electrolytes dissociate to make ions, because of it they conduct electricity.
Answer:
n=0.852 moles
Explanation:
Given mass is, m = 19.6 g
The molar mass of sodium is, M = 22.99 u
We need to find the no of moles in 19.6 of Sodium. We know that, no of moles is equal to given mass divided by molar mass.
So, there are 0.852 moles in 19.6 g of Sodium.
The answer is:
carboxylate
and protonated amines
The explanation:
when
The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.
and about protonated amines:
-alkyl groups improve the basicity, aryl groups diminish it.
-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.
- Primary amines are basic functions which could be protonated to the ammonium ion
