The sun of the protons a D neutrons in the nucleus of an atom is called the ATOMIC MASS
Hydrogen bonds are present in the following molecules: HF AND NH3
Dipole dipole inter molecular forces occurs the molecules of H2S AND H2.
Hydrogen bonding is an electrostatic attraction between two polar groups that occur when hydrogen atom covalently bound with highly electronegative atoms.
Answer:
Problem, Variables, Hypothesis, Research, Procedure, Data, Conclusion.
Explanation:
First, you have to know what the problem that you're talking about is. Then, you have to know the independent, dependent, and controlled variables are in order to make a hypothesis. Then do research about the topic. After that, you make the procedure your experiment, if that's what your doing. Then after the experiment, you find the data. Using that data, you make a conclusion.
Answer:
The lowest whole number mass ratio of nitrogen that combines with a given mass of oxygen is 1:1
Explanation:
In compound A, we have 14 g of nitrogen combine with 16 g of oxygen
In compound B, we have 14 g of nitrogen combine with 32 g of oxygen
Therefore, we have
A B
Ratio of molar masses 14:16 14:32
Mass of O that combine with 1 g of N 1.14 2.29
Dividing by the smallest mass ratio 1 2
Therefore the lowest whole number mass ratio at which oxygen and nitrogen can combine = 1:1.
