The correct answer is C) Bee, any living thing, such as a bee, cannot make its own food therefor it is a consumer
The compound sodium carbonate is a strong electrolyte because it completely dissociates when placed in water into its component ions. The equation of the reaction can be expressed as:
The dissociation leads to the formation of sodium and carbonate ions with the latter held together by its internal covalent bond.
This is unlike weak electrolytes that do not dissociate completely in water or aqueous solutions. Only a small fraction of the solute exists as ions in the solution.

Answer:
The purpose of the experiment is to see how water of different temperature and salinity affect the density.
Explanation:
Temperature and salinity directly affect the density of the water. Water of low temperature is more dense than water of high temperature, BUT, (fresh)water with no salt is less dense than (sea)water with more salt, so temperature and salinity change density of water.
The number of significant digits in the number 125,001 are: <span>6.
</span>Significant digits are always:
<span>1. non-zero
</span>2. <span>Any zeros between two significant digits are significant (for example 5 and 1)
</span>3. <span>A final zero or trailing zeros in the decimal portion only are significant.

Answer:
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
