Answer:
<h2>The advantage is that, you can add additional power devices usually using batteries.</h2>
<h2>The disadvantage is ... if one component in a series circuit fails, then all the components in the circuit fail because the circuit has been broken. </h2>

Answer:
option B is the correct answer
Answer:
C. Aluminum
Explanation:
Aluminum has 5.9858 ionization energy
Boron has 8.298 ionization energy
Silicon has 8.1517 ionization energy
Carbon has 11.2603 ionization energy
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
