Answer:
occur if two of the ions form an insoluble ionic compound, which precipitates out of solution
Explanation:
When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.
Answer:
Speed and acceleration
Explanation:
i would say this bc the formula is related to acceleration if you looking at all the possible exceptions im not a expert in this range but im just giving you what i would pick so if you get it wrong im sorry lol.
In comparing two isotopes of the same element, the atomic number, stays the same.
Allow me to explain: The protons in an isotope ALWAYS stays the same, but the neutrons change. But, what's the atomic number made up of?
Protons, which means it won't change.
However, the atomic mass is made up of neutrons + protons, so only the atomic mass would change - not the atomic number.
<span>As pressure increases, so does density. (A direct relationship). Inversely, as temperature increases, density decreases because of increasing volume.
so your answer is DIRECT
hoped it help :D
