Arguably A, B and C are all correct. Atoms of elements can form compounds such as NaCl(table salt). Molecules form molecular compounds and minerals are just complex molecule compounds.
The image<span> formed by a plane </span>mirror<span> is always virtual (meaning that the light rays </span>do<span> not actually come from the </span>image<span>), upright, and of the same shape and size as the object it is reflecting. A virtual </span>image<span> is a copy of an object formed at the location from which the light rays </span>appear<span> to come.</span>

Answer:
552.22
Explanation:
density=Mass/volume
therefore, Mass=density×volume
Mass=3.84*136
The most appropriate word among the group of answer choices to fill in the blank is: a. Random sample surveys.
Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
The various types of sampling used by researchers includes the following;
A random sample survey is also referred to as a simple random sample (SRS) and it can be defined as a sampling technique that involves randomly selecting a subset of a larger population. Also, any result obtained through the use of a random sample survey can be generalized and applied to a larger population.
In conclusion, scientists and researchers prefer random sample surveys because their results can be generalized to a larger population.
