Answer:
Petroleum and treating meals.
Answer:
Explanation:
A conjugate base is formed when an acid in reaction with a base lose a proton H+.
For example if RCOOH that is an acid, reacts with water that is a base, the RCOOH loses an H+ and it becomes that is the conjugate base; and the water gains the H+ and become the conjugate acid, that is:
*
The RCOO- is the conjugate base
*
In this case the is the conjugate base
*
The is the conjugate base
*
The is the conjugate base.
Answer:
7.8 grams per cm
Explanation:
to get density you need the mass and volume then you divide them so
81.9 grams/10.5 cm gives 7.8g/cm
Answer:
The sample obtained from the environment has a higher mass
Explanation:
A simple way to put the answer is that the element carbon -as found in nature- has a molar mass of 12.0107 g/mol, because there are a few isotopes of 14C and 13C; and <em>the molar mass is an expression of the isotopes' natural abundance</em>.
So 1 mole of carbon obtained from the environment would weigh 12.0107 g, while a sample of isotopically pure carbon would weigh 12.0000 g.
