Answer:C) the measurement is close to the accepted value and can be reproduced.
Answer:
0.75 M
Explanation:
Molarity = moles of solute / liters of solution
so;
Molarity = ![\frac{1.5 Moles}{2.0 Liters}](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%20Moles%7D%7B2.0%20Liters%7D)
Answer:
O3 => CLO + O2
Explanation:
ozone gas yields one Chlorine Monoxide gas, and two Oxygen gas. i forgot how to explain it well, but I know how to do it and will help in the future if needed :)
Answer:
2.60 M
Explanation:
M1V1=M2V2
Where
M1 = ?
V1 = 20.9 mL
M2 = 2.548 M
V2 = 21.39 mL
(?)(20.9 mL) = (2.548 M)(21.39 mL)
------------------ -----------------------------
(20.9 mL) (20.9 mL)
? = (54.50)/(20.9) = 2.60 M
(Side Note: the mL cancel each other out to leave M units only)
Answer:
Covalent bonds
Explanation:
There are about three kinds of bonds in chemistry;
Ionic bonds
Covalent bonds
Metallic bonds
Substances that possess ionic and metallic bonds all have high melting and boiling points.
However, covalent molecules often have low melting and boiling points due to weak intermolecular forces in the solid state. They also have a dull appearance and do not dissolve in water.
