Answer:
Explanation:
= Volume of NaOH = 34.56 mL
= Volume of HCl = 25 mL
= Concentration of NaOH = 0.25 M
= Concentration of HCl
When endpoint is reached the number of moles of NaOH will be equal to the number of moles of HCl
Concentration of HCl is .
Jupiter has greater gravitational pull than earth, about 2.4 time greater than that of earth. This means that a person weighing 100 pound on earth will weigh 240 pounds on Jupiter.
Jupiter is the largest planet in the solar system. It is so large that all other planets would comfortably fit inside it. It is over 1000 times bigger than the earth.
Jupiter is the fifth planet from the sun and rotates faster than any other planet. A day in Jupiter is about 10 hours long.
Explanation:
Elements need a total of eight electrons to gain stability and look like a noble gas. So, they sometimes need sharing of two, four or even six electrons to complete their octate. So, they form double and triple covalent bonds. One more the reason is the interaction between the p orbitals of the combining atoms. for example A double bond, as in ethene H2C=CH2, arises from one combination of the s orbitals and one combination of the p_y orbitals.
The elements in each group have the same number of electrons in the outer orbital. Or also called valence electrons. Khan academy has a great video online explaining why this happens. (It only happens for main group elements). Here is a link (sorry you can’t click it in Brainly) https://www.khanacademy.org/science/chemistry/periodic-table/copy-of-periodic-table-of-elements/v/periodic-table-valence-electrons. Feel free to message me for a better explanation, I would explain now but I’m not sure how much you know about this. If you know how to write an electron configuration you can see how all the electron configurations for the same group (not the transitional metals only the main groups) have the same number of valence electrons. I hope that helped, sorry I was vague about the explanation :)
