Answer: All of these options have some value in explaing why data need to be analyzed. The best single option would be, in my opinion, to find a pattern.
Explanation: The answer above does not address other valid reasons. An evaluation will add some confidence limits to your data, and therefore conclusions.
Which of the following statements is correct for isotopes of an element?
What caused the ice cube to melt? What do you think is happening to the particles on the inside of the ice cube as it melts?
Answer:
Ice melts when heat is provided to it.
Explanation:
When heat is provided, the kinetic energy of the particles increases. The particles start vibrating. As you keep providing heat, the particles start vibrating more strongly and with greater speed. Some particles become so energetic, that they are able to break the force of attraction and move away as a liquid.

Why is sodium a significant source of calories in both foods
Answer: Sodium is made up of lots of salt.
Explanation:
Eating a lot of salt can cause your body to retain more water, which can show up on the scale as extra pounds. But we're not just talking about water weight here. High salt diets appear to be linked to higher body fat in particular, the kind of fat that accumulates around your middle.

Which atom would be neutral?
1. An oxygen atom with 16 electrons, 18 protons, and 16 neutrons
2. An oxygen atom with 4 electrons, 6protons, and 4 neutrons
3. An oxygen atom with 8 electrons, 8 protons, and 9 neutrons
4. An oxygen atom with 9 electrons, 8 protons, and 8 neutrons
Answer:
3 is the answer
Explanation:
as the number of electrons =number of protons
so the negatively charged particles= positively charged particles

how can fossil records be useful to determine the relative ages of rock layers and other fossils?
Answer:
If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.

Answer he isn't interested in learning about you
Explanation: i hope u are okay queen
9. Apply: Atoms are most stable when their outermost shell is full. If their outermost shell is not
full, atoms tend to gain, lose, or share electrons until the shell fills up. While doing this,
atoms react and form chemical bonds with other atoms.
Based on this, what can you infer about the reactivity of helium and neon?
Answer:
helium and neon are both noble gases their outermost shells are full or stable the elements will agree with the statement s above

The compound XCl4 contains 75.0% Cl by mass. What is the
element X?
nch of the following
The element X is titanium.
According to the question, the percentage by mass of Cl in XCl4 is 75.0%.
The percentage by mass is obtained from;
Mass of element in the compound/molar mass of compound * 100
Hence;
Let the mass of the unknown element be X
75 = 142/X + 142 * 100
75 (X + 142) = 142 * 100
75X + 10650 = 14200
75X = 14200 - 10650
X = 14200 - 10650/75
X = 47
Hence, X is titanium.
