Answer:
144 g
Explanation:
Use the mole ratio of 4 mol CO2 for every 9 mol O2 to convert from mol O2 to mol CO2. Then use the molar mass of CO2 to convert from mol of CO2 to grams of CO2.
7.34 mol O2 • (4 mol CO2 / 9 mol O2) • (44.01 g CO2 / 1 mol CO2) = 144 g CO2

<span>There would be two electrons in the 1s orbital one oriented up and one oriented down. The other electron would be in the 1p orbital up or down.
Remember that 1s can only hold 2 electrons at a time, and when it is filled there one electron is spinning up and the other is spinning down. After 1s, comes the 1p orbital which can hold 6 electrons. Until 3 electrons are spinning either up or down, the next one will have the next orientation.</span>
Answer:
a)beta decay; to reduce the number of neutrons
Explanation:
When an isotope decays by beta decay, a neutron is converted into a proton, an electron and a neutrino (a particle that serves to balance spins). This process reduces the neutron/proton ratio.
During the beta decay of carbon-14, an atom of 14C decays into an atom of 14N. Hence the number of protons in the atom increases by one, creating a nitrogen atom.
