A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5 m/s^2 what is the mass of the bowling ball?
Kruka [31]

Data:

F (force) = 22.0 N

m (mass) = ? (in Kg)

a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

4.0 kg

I hope this helps. =)

I need help:<br>Ionic Compounds are formed from atoms that have opposite charges. True Or False?
liq [111]

It is <u>true</u> that ionic compounds are formed from atoms that have opposite charges.

<h3>What are ionic compounds?</h3>

Ionic compounds are chemical compounds made up of ions held together by electrostatic forces termed ionic bonding.

The ionic compound formed is neutrally charged but consists of positively charged ions called cations and negatively charged ions called anions.

For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions. The result is the formation of an ionic compound with cation Na+ and anion Cl– ions.

Therefore, it is true that an ionic compound is made up of positive and negative ions.

Explain how you would expect the strength of
LekaFEV [45]

Answer:

  • <u><em>You should expect that the ionic bond in LiBr is stronger than the bond in KBr.</em></u>

<u><em /></u>

Explanation:

The<em> ionic bonds</em> are formed by the electrostatic attraction between the ions, cations and anions.

In KBr the cation is K⁺ and the anion is Br⁻.

In LiBr the cation is Li⁺ and the anion is Br⁻.

You must expect that the bond strength depends mainly on the charges present on each ion and the distance between them.

Nevertheless, the effect of the distance between the radius dominate the trendency of the bond strength, which makes that the ionic strength trend be related to the ionic radius trend.

Lithium is a smaller ion than Potassium (both are in the same group and Lithium is above Potassium).

Thus, you should expect that the Li ion is closer to the Br ion than what the K ion is to the Br ion and expect that the bond between a Li ion and the Br ion be stronger than the bond between the K ion and the Br ion.
