1 In a lab report, students must write out the word equation for Zn + Pb(NO3)2 = Zn(NO3)2 + Pb. What is the correct word equation? A Zine and lead nitrate react to form zine nitrate and lead, Zine and lead (II) nitrate Feast to form zine nitrate and lead, c Zine and lead nitrogen oxide react te ferm zine nitrogen exide and lead, Zine and lead (II) nitrate react to form zine nitrite and lead (11)

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

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.

When a beta particle is emitted, the mass number of the nucleus a. decreases by one b. increases by one c. remains the same d. decreases by two
