Answer:
The answer is b. Carbon Tetrachloride
Explanation:
Let's discard the other options:
a. It couldn't be carbon chloride because there are four (4) chloride ions in the molecular formula. The molecular formula for the carbon chloride must be CCI. So, this answer is wrong
c. It could be monocarbon tetrachloride because there are 4 chloride ions and 1 carbon ion, but it's not necessary to use the prefix "mono" because there is just one carbon ion in the formula. In that way, when we mention carbon in the name, there is implicit that there is just one carbon atom in the formula. So, this answer could be ok, but isn't the best.
d. It couldn't be calcium chloride because there isn't any calcium ion or atom in the formula. The molecular formula for the calcium chloride must be CaCI. So, this answer is wrong

Answer:
E) 1.56x10⁴g
Explanation:
Pounds and grams are both units of mass. Pounds are used in UK and USA. Grams is the unit of mass used in the international system of units, SI.
To convert pounds, lb, to grams, g, we need the equivalence between these 2 units of mass:
1lb = 453.6g
That means 1lb weighs 453.6g. 34.4lb weigh:
34.4lb * (453.6g / 1lb) = 1.56x10⁴g. That means right option is:
<h3>E) 1.56x10⁴g</h3>
