Answer:
1.1713 moles
Explanation:
RFM of N2O5=108
Moles of N2O5= mass/RFM= 63.25/108=0.5856 moles
Mole ratio of N2O5:NO2= 2:4
Therefore moles of NO2= 4/2*0.5856= 1.1713 moles
A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.
Pretty sure it’s C the added products drives reverse reaction and since forward releases heat, reverse would absorb.
