The answer would be color. The temperature affects the brightness and the shade of the star.
The uranium within these items is radioactive and should be treated with care. Uranium's most stable isotope, uranium-238, has a half-life of about 4,468,000,000 years. It decays into thorium-234 through alpha decay or decays through spontaneous fission.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us obtain the mass of carbon in the sample by applying the following stoichiometric factor, considering that the only source of this atom in the sample is contained in the produced 361 mg of CO2 and one mole of this compound contain one mole of carbon atoms whose mass is 12.01 g/mol or mg/mmol as shown below:
Regards!
The compound contains:
Nitrogen = 13.360%
Hydrogen = 3.8455%
Boron = 10.312%
This implies that for every 100 g of the substance:
Mass of nitrogen = 13.360 g
Mass of hydrogen = 3.8455 g
Mass of Boron = 10.312 g
Atomic mass of N = 14 g/mol
Atomic mass of H = 1 g/mol
Atomic mass of B = 11 g/mol
# moles of N = 13.360/14 = 0.9543
# moles of H = 3.8455/1 = 3.8455
# moles of B = 10.312/11 = 0.9375
Divide by the smallest # moles:
N = 0.9543/0.9375 = 1.02
H = 3.8455/0.9375 = 4.10
B = 0.9375/0.9375 = 1
Empirical formula = NH4B
