The nuclear binding energy of one nitrogen-14 atom is (BLANK) x 10A J. Round to 3
d1i1m1o1n [39]

mass defect = mass of constituents - mass of atom

N has 7p and 9n

proton mass ~ 1.00728 amu

neutron mass ~ 1.00866 amu

electron mass ~ 0.000549 amu

Nitrogen mass ~ 14.003074 amu

mass defect = (7*1.00728)-(7*1.00866)-(7*0.000549) - 14.003074

= 0.11235amu

convert to energy, the binding energy = 1.68x10^-11 J

characteristic properties of an element are the defining properties of that element and it does not change with quantity of the element used.

Explanation:

the amount or the quantity of the element used does not affect the characteristic property of the element. it does not matter is the if the amount or the quantity of the element used in the reaction is large  or the small the characteristic properties like boiling point, melting point, density, thermal conductivity, etc remain the same or remain constant.

A car travels 2.5 hours in a Northern direction for 300km. Determine the cats speed and velocity
nika2105 [10]

Answer:

Velocity = 120 km/h in north

Speed  =  120 km/h

Explanation:

Given data:

Distance = 300 km north

Time taken = 2.5 hr

Speed and velocity = ?

Solution:

Speed = distance / time

Speed  = 300 km / 2.5 h

Speed  =  120 km/h

Velocity = change in position / change in time

Velocity = 300 km north /  2.5 hr

Velocity = 120 km/h in north
