Answer:
c) Fullerene and carbon nanotubes because they have empty spaces inside the molecules
Explanation:
Fullerene and carbon nanotubes would be the most desired in order to hold the cancer fighting drugs and to carry them through the body safely.
Answer:
Potassium (K) [First element in period 4]
Answer:
4 pairs are needed for the bonds, leaving 1 lone pair. Each double bond uses 2 bond pairs and can be thought of as a single unit. There are 2 double bond units and 1 lone pair, which will try to get as far apart as possible - taking up a trigonal planar arrangement.
Answer : The heat energy needed would be, 6486.5125 J
Explanation :
To calculate the change in temperature, we use the equation:
where,
q = heat needed = ?
m = mass of aluminum = 223 g
c = specific heat capacity of aluminum =
= change in temperature
= initial temperature =
= final temperature =
Putting values in above equation, we get:
Therefore, the heat energy needed would be, 6486.5125 J
with different properties are formed?
The chemical reaction indicate the formation of new substance by change in nature of original compound and shows chemical changes in the reaction.
Chemical reaction is defined as process in which two or more molecules collide with the proper orientation and enough force to produce a new product.
It is also defined as a procedure in which one or more compounds, known as reactants, are changed into one or more distinct substances, known as products.
There are mainly seven types of reaction.
Thus, the chemical reaction indicate the formation of new substance by change in nature of original compound and shows chemical changes in the reaction.

Answer:
Changes in Properties Changes in properties result when new substances form. For instance, gas production, formation of a precipitate, and a color change are all possible evidence that a chemical reaction has taken place. ... Change in Color A color change can signal that a new substance has formed.
Explanation:
Answer:
0.01454 grams of oxygen is present per kilogram of human muscle.
0.1454 grams of oxygen is present per kilogram of sperm whale muscle.
Explanation:
Given : The myoglobin is fully saturated with oxygen gas.
Moles of myoglobin = Moles of oxygen gas
Molecular mass of myoglobin = 17,600 g/mol
(assumed same fro whale and human )
Myoglobin content in humans = 8 g/kg
Mole of molyoglobin in human muscles per kg :
Mass of oxygen present in per kg of human muscle:
Moles of oxygen gas × 32g/mol :
g/kg of human muscle
Myoglobin content in whales= 80 g/kg
Mole of molyoglobin in whale muscles per kg :
Moles of myoglobin = Moles of oxygen gas
Mass of oxygen present in per kg of sperm whale muscle:
Moles of oxygen gas × 32g/mol :
g/kg of whale muscle
