The answer would be color. The temperature affects the brightness and the shade of the star.
The limiting reactant will be HCl.
<h3>Limiting reactants</h3>
They limit the amount of products produced in reactions.
From the equation, the mole ratio of Mg to HCl is 1:1.
Mole of 4.00 g mg = 4/24.3 = 0.1646 moles
Mole of 3.2 g HCl = 3.2/36.458 = 0.0878 moles
Thus, Mg is in excess while HCl is limiting in availability.

Answer:
B = Atoms can not be created or destroyed by chemical reaction.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Answer:
10. Embryology is the branch of biology and medicine concerned with the study of embryos and their development.
11. I think the answer is, Both humans and whale embryos have a tail and a backbone (I'm not sure).
12. Basilosaurid, any member of the family Basilosauridae, an early group of whales that lived from the middle Eocene to the late Oligocene Epoch (about 41 million to 23 million years ago).
13. Protocetids had long snouts, large eyes, and their nasal opening was farther caudally than in earlier archaeocetes.
14. Two ways we know that Maiacetus was a whale re:
1) Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.
2) Their hip bones were strong enough to walk on land, but their short legs combined with long flat fingers and toes suggest they would have had difficulty walking.
15. The name Maiacetus means Mother Whale. Maiacetus is significant because of how well the skeletons were preserved.
Hope this helps! :D
