Answer:
no im made outta atoms and stuff like that
Explanation:
Answer:
2.5x10^–3 mole.
Explanation:
Data obtained from the question include:
Volume of solution = 25mL
Molarity of HNO3 = 0.1M
Mole of HNO3 =..?
First, we'll begin by converting 25mL to L. This can be achieved by doing the following:
1000mL = 1L
Therefore, 25mL = 25/1000 = 0.025L
Now, we can obtain the number of mole of HNO3 present in the solution as follow:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 0.1 x 0.025
Mole = 2.5x10^–3 mole.
Therefore, 2.5x10^–3 mole of HNO3 is present in the solution.
None of the above, deoxyribonucleic acid is the full name of the abbreviation DNA
Answer: Option (b) is the correct answer.
Explanation:
When an atom is attached to another atom through sharing of electrons then bond formed between the atoms is known as a covalent bond. And, a bond formed by transfer of electrons from one atom to another is known as an ionic bond.
For example, electronic configuration of hydrogen is 
and electronic configuration of oxygen is 
. So, in order to attain stability hydrogen needs 1 more electron and an oxygen atom needs two electrons.
Therefore, two hydrogen atoms need to covalently bond through an oxygen atom leading to the formation of 
.
Thus, we can conclude that the electronegative oxygen that is central to a water molecule is covalently bound to two hydrogen atoms. These hydrogens are 'bent' to form a 
angle because four of the outer e- about oxygen are shared with hydrogens.
ENERGY depends on the number of particles. ... the movement of matter due to differences in density that arecaused by temperature variations; can result in the transfer of energy as CONVECTION involves the movement of matter due to differences in density.
they are called convection
sorry if I'm wrong but I hope this helps you
