The bent rod is supported at a b and c by smooth journal bearings. determine the components of the reaction at the bearings if the rod is subjected to the force of = 800n. the bearings are in proper alignment and exert only force at reactions on the rod

Used the balanced equation 2h2+ o2 - -> 2h2o. if you have 7.2 grams of o2 , how many grams of h2o can you produce ?

How many neutrons does a atom of cobalt have?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
