Answer:
pI = 6.16
Explanation:
The pI is given by the average of the pKas that are involved. In this case,
Pka of carboxylic acid was given as 2.72 and that of the Amino group was given as 9.60. the average would then be ½(2.72+9.60)
= 6.16
Answer:
20 m/s^2
Explanation:
given,
final velocity (v) = 6000m/s
initial velocity (u) = 0m/s
time taken (t) = 5 minutes
= 5×60second
= 300second
acceleration(a) = ?
we know that,
a = (v-u)/t
= (6000-0)/300
= 20 m/s^2
The number of particles in 46g of Sodium (Na) atoms are 2.00088735004 mol
A good example is table salt
Table salt at room temperature is a lattice structure-- meaning its ions are SUPER close to each other and hence can't flow.
If you look at electrical insulators, it simply means they can't carry charge-- because there's no flow of charge.
If you dissolve table salt or melt it, it becomes Dissociated meaning NaCl becomes Na^+ and Cl^-
So now they are separated, and they are ions (charged particles)-- because they are separated they can flow, and because they are charged, they carry a charge. Hence, a flowing charge when they are melted (at super high temperatures) or dissolved (yes, even at room temperatures)
