Answer:
Uranium can be isolated from its ores by dissolving it as UO 2(NO3)2, then separating it as solid UO2(C2O4)∙3H2O.
amu stands for atomic mass unit. this is the approximate weight of one proton or neutron. since it is 65.39 you could not have an actual zinc atom that weighed 65 and 39/100s of an atomic particle. instead this number is the average weight of a bunch of zinc particles that differ in numbers of whole amu numbers.
Combustion. As they are heated at extreme temperatures to form ammonia through Haber process
Answer:
0.218mol
Explanation:
Using Avogadro's law equation;
Va/na = Vb/nb
Where;
Va = volume of gas A
Vb = volume of gas B
na = number of moles of gas A
nb = number of moles of gas B
According to the information in this question,
na = 0.4mol
nb = x mol
Va = 220ml
Vb = 120ml
Using Va/na = Vb/nb
220/0.4 = 120/x
Cross multiply
0.4 × 120 = 220 × x
48 = 220x
x = 48/220
x = 0.218mol
