Dissolve the sugar. Strain the pebbles. You are left with the pepper
Answer:
See explanation
Explanation:
The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.
There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.
Answer:
Explanation:
Sn + 2HBr = SnBr₂ + H₂
Here HBr is an acid but Sn is not a base . It is a metal . So it is not an acid - base reaction .
HCl + KOH = KCl + H₂O
HCl is an acid and KOH is a base so it is an acid base reaction.
2AlCl₃ + 3Ca(OH)₂ = 2Al(OH)₃ + 3CaCl₂
It is an acid base reaction . It is so because aluminium hydroxide is a lewis acid and calcium hydroxide is a base . So it is an acid base reaction .
2C₂H₆ +7O₂ = 4CO₂ + 6H₂O
It is not an acid base reaction . It is actually an example of oxidation reaction in which ethane burns in oxygen to give carbon dioxide and water.
The cost for CHOPS is in the sand and the extraction of the oil from sand.
The cost for SAGD is the generation of steam.
The benefit for CHOPS is the low cost.
The benefit for SAGD is high extraction efficiency.
The other factors that could affect the decision are fuel cost and the required purity of the oil.
