Answer:
The easiest way to separate a mixture of sugar and water is to use distillation, a process that separates substances based on their different boiling points.
hope this helps
Whit this information I only can say the amount of sugar in the 4.000 g will be equal to the 31.67 % of the amount of sugar in the 12.630 g of the milk chocolate, assuming the sugar is evenly distributed in the chocolate. I am missing the value of the amount of sugar in the 12.630 g of chocolate to be able to calculate the value in mg
<span>In 2013, MIT biophysicist proposed a new theory that atoms can restructure themselves to dissipate more energy under the right conditions (external energy and heat)-atoms, therefore, can take on qualities we associate with life. According to his theory, this may be the basis for lifeform as we know it.</span>
Answer:
The theoretical yield of the hydrogen sulfide is 68.0 grams.
Explanation:
Moles of aluminum sulfide = 4.0 mol
Moles of water = 4.0 mol
According to reaction, 6 moles of water reacts with 1 mole of aluminum sulfide,then 4 moles of water will react with :
of aluminum sulfide
1.5 moles aluminum sulfide < 4 moles aluminum sulfide
This means that water is present in limiting amount and aluminum sulfide is in excess amount.So, amount of hydrogen sulfide will depend upon moles of water.
According to reaction, 6 moles of water gives with 3 mole of hydrogen sulfide,then 4 moles of water will give :
of hydrogen sulfide
Mass of hydrogen sulfide:
2.0 mol × 34 g/mol = 68.0 g
The theoretical yield of the hydrogen sulfide is 68.0 grams.
