Answer:
Both
Explanation:
Baking soda is the common name of sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .
Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.
If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.
Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.

From which one of these items will water evaporate at a different rate?a. Factory
Answer: The rays of the summer sun, high in the sky, arrive at a steep angle and heat the land much more than those of the winter sun, which hit at a shallow angle. Although the length of the day is an important factor in explaining why summers are hot and winter cold, the angle of sunlight is probably more important.

Lack of food, space, and imbalance of predator and prey
Answer:
The birds do not breed with each other where their territories overlap.
Explanation:
The correct answer would be that the birds do not breed with each other where their territories overlap.
<em>A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.</em>
<u>Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid</u>.
Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
