Answer:

- 83.33 m per second square

Explanation:

Initial velocity u = 10,000 m/s

Final Velocity v = 5,000 m/s

Time t = 1 minutes = 60 seconds

Acceleration a =?

\because \: a =  \frac{v - u}{t}  \\  \\  =  \frac{5000 - 10000}{60}  \\  \\  =  \frac{ - 5000}{60}  \\  \\ a =  - 83.33 \: m {s}^{ - 2}

The tiara worn by Kate Middleton for her wedding to Prince William of England contains 888 diamonds and belongs to the British m
allsm [11]

Answer:

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.

Explanation:

Number of diamonds ion tiara = 888

Mass of  each diamond = 1.0 carat = 0.200 g (given)

Mass of 888 diamonds in tiara:

888\times 0.200 g=177.600 g

Given that diamond is a form of carbon.

Atomic mass of  carbon atom = 12 g/mol

Moles of 77.600 g of carbon =\frac{177.600 g}{12 g/mol}=14.800 mol

Number of atoms of carbon 14.800 moles:

14.800 mol\times 6.022\times 10^{23} atoms =8.9125\times 10^{24} atoms

The number of atoms in the gemstones of that tiara is 8.9125\times 10^{24} atoms.

Explain how an ionic compound forms from these elements.
grin007 [14]

Ionic compounds are formed by the complete transfer of electrons from more electronegative elements to less electronegative elements.

7. <u>Sodium Nitride (Na₃N)</u> is an ionic substance.

8. The ionic formula for <u>Lithium Oxide is Li₂O</u>

9. The <u>compound SrF₂</u>

10. Aluminum Sulfide is a chemical compound with the <u>formula Al₂S₃.</u>

An ionic compound is a chemical compound composed of ions held together via electrostatic forces termed ionic bonding. The compound is neutral standard but includes definitely charged ions known as cations and negatively charged ions known as anions.

An ionic compound is a chemical compound composed of ions held collectively by means of electrostatic forces termed ionic bonding. The compound is neutral normal however consists of positively charged ions known as cations and negatively charged ions referred to as anions. Ionic compounds incorporate ions and are held collectively via the attractive forces of most of the oppositely charged ions.

Predict whether each of the following is soluble in water or not.
wlad13 [49]

Answer:

The soluble in water are a and b. c is not soluble in water

Explanation:

The water solubility of a compound, it depends its polarity (. KHSO4 has several polar molecules, actually it has ions charged positively like K and H, and charged negatively like sulfate (SO4-2). When it happens, molecules can do hydrogen bridges with water. It is because of above, KHSO4 can be used in wine making. Something similar happens with propylen glycol but in this case the polar part is OH- ions. Benzene has not polar parts. It is totally apolar compound.

I hope my answer helps you
