Stoichiometry Reaction Problem.. Help? When 100ml of 1M solution B is combined with 100ml of a 1M solution D, the resulting solution has a concentration of 0.250M of A, 0.1250M of B, 0.3750M ofC and no more substance D remains. 1. How many moles of each B and D are present before the reaction occurs? 2. How many moles each of A, B, C, and D are present after the reaction occurs? 3. How many moles of B and B have reacted? 4. What is the balanced equation for this reaction?

Strong conductivity of plasma allows it to act and react as and

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
