Calculate the number of molecules per unit volume in an ideal gas at STP. How is average atomic mass calculated? How do I count sigma and pi bonds and how do you determine the hybridization of certain atoms? What charges an atom? How many quarks are in (a) a baryon? (b) an antiba...
How many atoms are there in 65.8 g of H2O? How many water molecules can hydrogen bond to methanol? How many molecules are in 5.0 \text{moles} of water? How many different elements are in a water molecule? How many hydrogen atoms can bind to one carbon atom? A hydrogen atom has one ...
molecules and ions. Atoms : In Chemistry atoms are the basic unit of particles. An atom contains a nucleus (consisting protons and neutrons) and some electrons moving around the nucleus. If o atoms have the same number of protons they are the same element. There are about 117 e...
How many electrons are there in 1C?Charge:An atom is made up of electrons, protons, and neutrons. The positively charged nucleus is made of protons and neutrons whereas electrons revolve around the nucleus. The protons are positively charged and the electrons have an equal amount of negative ...
atoms (as opposed to molecules)do not have colors- they are clear except under special conditions.. Do atoms move? The atoms vibratebut stay in fixed positions because of their strong attractions for one another. Heating a solid increases the motion of the atoms. An increase in the motion ...
Super-tiny subatomic particles areused to create the parts of atoms. Protons, neutrons, and electrons can then organize to form atoms. Atoms are then used to create the molecules around us. How an atom is formed? Atoms are made up of a nucleus, protons and electrons. ... Atoms were cre...
How many sulfur atoms are in one mole of Al2(SO4)3? How many (a) sulfur molecules and how many (b) sulfur atoms are there in 1.00 mol S_8? How many atoms are in 24.0 grams of sulfur? How many atoms are in 13.0 grams of sulfur? How many atoms are in 16.3 grams of sulfur?
Of course, we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface, incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a...
To do this, look up atomic masses on the periodic table and use the formula mass to know how many atoms of each element are in a compound. Remember, subscripts in a formula indicate the number of atoms. If there is no subscript, it means there is only one atom of that element in th...
Molecules:Molecules are small particles of a substance made from two or more atoms. If the atoms come from different elements, the molecule will be called a compound. Molecules can have as few as two atoms or hundreds of atoms.Answer and Explanation: ...
