Answer:
Homogeneous - With a uniform appearance
Heterogeneous - With visible differences in the mixture
Explanation:
Referring to mixtures, homogeneous looks the same throughout, while heterogeneous has particles or whatnot.
Basically:
Homo means same
Hetero means different
A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The 2-HEPTANONE molecule contains a total of 21 bond(s) There are 7 non-H bond(s), 1 multiple bond(s), 4 rotatable bond(s), 1 double bond(s) and 1 ketone(s) (aliphatic).
I believe the answer is D.
Scientists are biased, and want to prove their specific hypothesis is right.
Given that the pressure, temperature and area of effusion is constant, the rate of effusion is inversely proportional to the square root of the molecular mass of the gas.
Mr Oxygen = 32
Mr Argon = 40
Effusion Oxygen = 1/√32
Effusion Argon = 1/√40
Effusion Oxygen / Effusion Argon = √(40) / √(32)
=√(40/32) = √(5/4) = 1.19
Thus, Oxygen will effuse 1.19 times faster than Argon. The second option is correct.
Answer:
"Synchronize" means to place together in terms of time and manner.
Explanation:
- In the word 'synchronize' the prefix added is 'syn'.
- The prefix 'syn' has been derived from the Greek language.
- The prefixes 'syn' and 'sym' are equivalent in terms of their meanings.
- The meaning of the prefix is to put 'together'.
- The words formed by adding the prefix es 'syn' and 'sym' highlights the meaning of togetherness of the specific things.
