22.6 x 10^5 J
‘Heat of vaporization’ is the amount of ‘heat’ required to convert '1g' of mass of a liquid to vapor. Normal “boiling point of water” is 100 C. The heat of vaporization at this temperature is 2260 J/g. It means 2260 J/g of heat is required to convert ‘1g of water’ to 1g of vapor at 100 C. So to convert 1 kg of mass of water or 1000g of water we require 22.6 x 10^5 J of heat.
Answer:
You find a separatory funnel set up in a fume hood. There are clearly two visible layers. Describe a method you could use to determine which layer is the aqueous layer.
Explanation:
In the separating funnel, the liquid with less density exists at the top layer and the liquid with greater density will exist at the bottom layer.
To identify the aqueous layer, add a bit of water to the separating funnel.
Then, observe where the water will go and mix.
If it mixes with the bottom layer, then the bottom layer is the aqueous layer.
If water mixes with the top layer, then top layer is the aqueous layer.
The sequence given above are sequential steps which usually take place in THE FOUR STROKE ENGINE CYCLE. The correct option is A. The four stroke cycle engine is an internal combustion engine which used four piston stroke to complete one operation cycle. The first step, which is intake stroke takes air and fuel into the combustion chamber. The second step, which is the compression stroke compresses the mixture into a smaller volume. In the third step [ expansion stroke], the fuel is ignited by the spark and in the fourth step [exhaust stroke], left over gases are pushed out through the exhaust pipe.
Answer:
you mean "jointed." jointed appendages give arthropods much greater movement flexibility and range.
Answer:
An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.
ate = one more O than -ite
Explanation:
Example:
NO2 is nitrite
NO3 is nitrate
You can see that the molecules are made of the same elements, however they have more or less of one of the elements (i.e. oxygen).
