Answer:
A. since Nitrogen has 7 electrons and when it gains 3 electrons it will have 10 electrons. using short hand rule it is [Ne]
Multiply .800 moles of O2 by Avagadro's number divided by 1 mole. This will get rid of the moles on the bottom and leave you with molecules. So technically .800 times 6.02x10^23.
Aniline has smallest Rf value on silica gel since it is more polarthan the other compounds because aniline is a hydrogen donor and acceptor itmakes the molecule more attracted to the silica gel which is also also polar as<span>‘likes dissolve likes.’</span>
Answer:
d = 3 g/cm³
Explanation:
Given data:
Mass of stone = 27 g
Volume of water = 10 cm³
Volume of water+ stone = 19 cm³
Volume of stone = ?
Density of stone = ?
Solution:
Volume of stone = total volume - volume of water
Volume of stone = 19 cm³ - 10 cm³
Volume of stone = 9 cm³
Density of stone:
d = m/v
d = 27 g/ 9 cm³
d = 3 g/cm³
Beta decay which is also sometimes referred to as beta emission is a phenomenon in which a certain element releases an electron. For this case, each carbon has an atomic number of 6, leaving us with 8 neutrons, now, the mass number will be retained and the atomic number will be decreased by one. Thus, the answer is Boron-14.
