in water the electrons will be towards the oxygen since it is more electronegative than hydrogen so the repulsion between bp-bp will oppose the repulsion between lp-bp but in oxygenfluoride electrons will be towards fluorine so repulsion will be less so bond angle is less than water

How many copper atoms are in a pure copper statue with a mass of 133 kg?
A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------
How do I calculate these problems wavelengths in nm?
4 min/mile is about 6.7 m/s to convert to nm you times your answer by 1e9 (1x10^9) (6.626e-34) / (83)(6.7) = 1.19e-27 nm Frist convert 6.00e27 g to kg Second calculate and you'll get an answer in m (6.626e-34) / (6.00e24)(2.90e4) = 3.81e-54 nm
How many nuetrons are in arsenic?
42 neutrons Think of it this way: Arsenic 75. The number of protons and electrons of an element are always the same. Well, we obviously know that there are 33 electrons in arsenic from the periodic table, and therefore we have 33 protons. So, to find the number of neutrons is simple. The number of neutrons and protons added together will equal the mass number (75). So it is basic algebra. You want to think logically. Take75 (your mass number) and subtract 33 (the number of protons) and you will get 42. Hope that helps!
Does your body contain more neutrons than protons?
Short Answer:There are more protons than neutrons in the human body.This is primarily because we are mostly water and H2O is mostly hydrogen. Hydrogen is a single proton and is 25% of all the atoms in the body.Of the six elements that make up 99% of the mass of the human body (oxygen 65%, carbon 18%, hydrogen 10%, nitrogen 3%, calcium 1.4%, phosphorous 1.1%), all but hydrogen and phosphorous have an equal number protons and neutrons in the dominant isotope and hydrogen, be 25% of all atoms, overwhelms the balance giving more protons than neutrons.Long Answer:The human body (and other living things) contains a much greater number of protons than neutrons. Consider the data from the "related links" below which describe the elemental composition of the human body. This data allows one to calculate the number of neutrons and protons for each element and determine that there are about 4.15*10^27 protons more than the number of neutrons.Perform the following calculations for each of the elements on the list: determine the difference between number of neutrons and protons in the atomic nucleus and call it N-P ('N' minus 'P') for each element; divide the mass in grams of the element in the human body by the atomic mass of the element to get the moles of the element in the human body; multiply the moles by Avagadro's constant (~6.022*10^23) to get the number of atoms; multiply the number of atoms with N-P to get the net neutrons for the element.The list at the cited webpage is conveniently in order of most abundant to least abundant. If we look at only the first fifteen elements at the ones that have N-P not equal to zero we find that the net neutrons is on the order of -(10^27). This is due to the fact that Hydrogen has 1 proton and 0 neutrons (N-P = -1), and with a mass contribution of 7 kilograms to the human body, adds nearly 7000 moles of protons. Note, I'm ignoring the rest of the elements on the list after Cadmiun (the fifteenth with N-P != 0) since the mass contribution after Cadmium is less than 0.050 grams, none of the remaining elements should be able to contribute enough neutrons to increase the net neutrons into positive range. (The trend is much more clear if you perform the calculations and list the elements.)Additionally, although Carbon makes up ~16 kilograms of the body, the amount of isotopic carbon is only about 1% of that value at most, so the contribution from isotopic carbon would be only about 160 grams, which if it were all C14, would only add 1.38*10^25 neutrons.
