Answer:

119

Explanation:

Tin is present in group sixteen. Its atomic number is 50 and atomic weight is 119 amu.

The atomic number is the number of electrons or number of protons. The atomic mass is equal to the sum of number of protons and number neutrons.

Tin have 50 protons and 69 neutrons.The atomic weight will be 50+69 = 119 amu.

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons.

In the molecule NO2 which element is pulling the electrons
Andrei [34K]

The bond between the N and 0 (double bond) transfers and gives a -ve charge on O and a +ve charge on N atom at the group . Thus the +vely charged nitrogen is electron-deficient pulling electrons towards itself!

The combination of the +vely charged nitrogen and the electronegative oxygen atom leads to delocalization causing the resonance effect.

Question 2 (5 points)
blagie [28]

The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.

Option D

<h3>Chemical Reactions</h3>

Generally,the experiment shows that  glass B temperature is higher than glass temperature A and this is given that observation that the solute dissolves faster in glass B than glass A.

Therefore,The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.

Setler79 [48]

Answer:

Water, wheel and paddles or bucket are the parts and mechanical energy is produced.

Explanation:

The parts of water wheel system are water, wheel and paddles or bucket. The main purpose of water wheel system is to generate useful energy by using the flowing or falling of water on the wheel. We use this water wheel system for the conversion of kinetic energy into mechanical energy such as water mill or hydroelectric plant in which the blades movement is responsible for the generation of electricity.
