Answer:
Explanation:
The atomic number tells you how many protons are in an element. Each element has a different number of protons, so a specific number of protons will also help you easily identify that particular element. For example, if you are given that an element has an atomic number of 1, you would know the element is hydrogen because other elements have different amounts of protons and thus different atomic numbers.
The answer the neutral atoms
Answer:
Explanation:
Density can be found by dividing the mass by the volume and using the following formula.
The mass of the cork is 30 grams.
The volume of the cork is 160 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the cork is 0.1875 grams per cubic centimeter or 0.1875 g/cm³
Claim: The aluminum boat will float
Evidence: A foil boat has less density over more space
Reasoning: Since the boat has little density the boat has the ability to float
The correct response would be C. Mass cannot be created nor destroyed in a chemical reaction.
