Answer:
To find the number of neutrons in an isotope, subtract the number of protons from the atomic mass of the isotope. The atomic number of the element equals the number of protons.
Physical changes are when things get changed without altering chemical consistencies, which is melting solid butter into liquid one, or boiling water. Chemical changes are things such as caramelizing sugar when making sweets, or when carbon dioxide is created and released when baking bread.
Answer:
5 cm³.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of Rock =.?
The volume of the rock can be obtained as follow:
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 40 – 35
Volume of Rock = 5 mL.
Finally, we shall convert 5 mL to cm³.
This can be obtained as follow:
1 mL = 1 cm³
Therefore,
5 mL = 5 mL × 1 cm³ / 1 mL
5 mL = 5 cm³
Thus, we can say that the volume of the rock is 5 cm³.
Answer:
Rabbit
Explanation:
I said rabbit because the snake feeds off the rabbit and that's where he gets his energy from. If the question asked you what is the primary source of energy in this food chain then the answer would be the sun. Since the question only asks you about the snake then the rabbit is the answer.
Hope this helps!
