Which of the following is the best name for a compound made from calcium and bromine? (CaBr2) calcium bromide calcium dibromide
Mice21 [21]

Answer:

Calcium bromide

Explanation:

When naming compounds, the use of prefixes depend on the type of bond made. In this case, calcium and bromine form a ionic bond because calcium is a metal and bromine is a non-metal.

Ionic bonds are not named using prefixes. So no matter how many atoms there are, you will simply write the name of the element for the first element.

For the second element, you name it as well, but only use the root name and end it with -ide.

A compound with a molar mass of 100.0 g/lol has an elemental composition of 24.0% C, 3.0% H, 16.0% O and 57.0%F. What is the mol
ch4aika [34]

If I made no mistake in calculation, the given answer must be correct...(tried my best)



elements   :                        carbon     hydrogen    oxygen       Fluorine

 composition [C]                     24             3                16                57

M r                                          12             1                16                19

(divide C by Mr)                       2               3                 1                  3


(Divide by smallest value)       2                3                  1                  3

(smallest value = 1...so all value remained constant)

Empirical formula : C2H3OF3


if molar mas = 100 g per mole, then

first step calculate Mr. of empirical formula:  [= 100]


Them molecular formula = empirical formula

What will be the effect on the solubility of BaF2 if the following changes are made: increasing temperature; adding NaF; adding
borishaifa [10]

In BaF₂ the solubility will decreases on adding NaF

the solubility will increases on adding HCl

<h3>SOLUBILITY OF BARIUM FLUORIDE</h3>
  • Increase in temperature will increase the solubility of the solid.
  • By adding NaF - decrease the solubility of BaF₂
  • By adding HCl - increase the solubility of BaF₂

<h3>BARIUM FLUORIDE</h3>
  • It is colourless solid that occur as rare mineral
  • It is corroded by moisture
  • It is used in window of IR spectroscopy

Hence the barium fluoride the solubility decreases on adding NaF and increases on adding HCl.
