What is the correct name for Au3N?
Reptile [31]

Answer:

option D= Gold (I) nitride

Explanation:

The name of the given compound is gold(I) nitride.

Molar mass can be determine by following way:

molar mass Au3N = (molar mass of gold × 3) + (molar mass of nitrogen)

molar mass Au3N = (196.97 × 3 ) + ( 14 )

molar mass of Au3N =  590.91 g/mol + 14 g/mol

molar mass of Au3N = 604.91 g/mol

The nitrogen has valency of -3 so three Au(+1) will require while the valency of Au is (1+) one nitrogen will require to make the compound overall neutral.

Au3N

3(1+) + (-3) = 0

+3 - 3 = 0

0 = 0

The overall charge is 0, the compound will be neutral.

What is the kinetic energy of a 5 kg object moving at 7 m/s?
valina [46]

Answer:

122.5 Joule, or 122.5 j

Explanation:

Given,

mass of the object (m) = 5 kg

velocity of the object (v) = 7 m/s

Kinetic energy = \frac{1}{2} × m × v²

Applying the formula:

Kinetic energy = \frac{1}{2} × 5 × 7²

⇒ \frac{1}{2} × 5 × 7 × 7

⇒ \frac{245}{2}

⇒ 122.5 Joule, or 122.5 j

Kinetic energy is the energy that an object gains as the result of the motion.  It also depends on the mass of the object and force with which the motion is applied.  In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
