Answer:
3 g/mL
Explanation:
density is mass divided by volume
The mass of the object is 450g, and the volume is 150mL (the water level changes by 150mL).
450g/150mL = 3 g/mL
Answer:
The limiting reactant is hydrogen.
Explanation:
According to the balanced equation for synthesis of water, hydrogen is used up twice as fast as oxygen -- we need two moles of H2 for every one mole of O2 when creating water.
Since we have 20 moles of oxygen, this means we would need twice as much hydrogen, or 40 moles, to use it all up. There is only 30 moles of hydrogen, which means that all the hydrogen will be used before the 20 moles of oxygen is used. Hydrogen limits production in this case.
1. Sugar refers to easily metabolized carbohydrate; sweetener is an additive that is added to foods for the sweetening effect
2. Sugar in all its forms does not require authentication; sweeteners need to be approved by an accreditation body or the EU
3. Sugar is caloric, while sweeteners can be caloric or non caloric in nature
4. Intensive sweeteners are prepared by synthetic procedure and provide little or no energy whatsoever; sugar substances eliminate the crucial minerals from your diet
