Answer:
<u><em>A. They don't form compounds</em></u>
Explanation:
- High density: The strong bonding between the atoms in transition metals cause them to be tightly held together, creating a high density. Colored compounds: Transition metals tend to form more colored compounds than other elements, either in solid form or dissolved in a solvent.
Boron (B) has 3 electrons in the outer shell.
Barium (Ba) has 2 electrons.
Phosphorus (P) has 5 electrons.
Manganese (Mn) has 2 electrons.
The answer is C) P (phosphorus).
Answer:
Depending upon the mass gathered, the next process formation varies:
Nuclear fusion can kick in leading to formation of star. The nuclei fuse to together and energy is liberated in the form of light and heat.
If sufficient mass is not gathered to start nuclear fusion reaction, gaseous planet forms like Jupiter.
In third case, even though sufficient mass is present (twice the mass of Jupiter) still no fusion reaction starts. Such bodies are known as failed stars or brown dwarfs.
The reaction of hydrochloric acid and sodium hydroxide is a neutralization reaction wherein a mixture of acid and base produces salt, water, and energy in the form of heat. A neutralization reaction is exothermic, thus producing heat. This is why the beaker felt warm to the touch.
