Cross-pollination
occurs when pollen from one plant transferred to a different plant with same
species. <span>The two
plants’ genetic material combines and the resulting seeds from that pollination
will have characteristics of both varieties thus producing stronger
plants. In addition, cross- pollination happens

Answer:
there are 0.074 moles in 2.3 grams of phosphorus
2Pb(NO₃)₂ = 2PbO + 4NO₂ + O₂
m{Pb(NO₃)₂}=9.9 g
m'{PbO}=5.5 g
M{Pb(NO₃)₂}=331.2 g/mol
M{PbO}=223.2 g/mol
w-?
w=m'{PbO}/m{PbO}
m{PbO}=M{PbO}m{Pb(NO₃)₂}/M{Pb(NO₃)₂}
w=m'{PbO}M{Pb(NO₃)₂}/[M{PbO}m{Pb(NO₃)₂}]
w=5.5*331.2/[223.2*9.9]=0.8244 (82.44%)
