1) In 1.31 g of a chloride of titanium, there is 0.528 g of titanium. What is the empirical formula of this titanium chloride?
kozerog [31]

Answer:

TiCl2

Explanation:

Mass of the chloride of titanium= 1.31 g

Mass of titanium= 0.528 g

Therefore mass of chlorine = 1.31-0.528 = 0.782 g

To determine the empirical formulae of the titanium chloride, divide the mass of each element by its relative atomic mass and divide through by the lowest ratio.

Ti- 0.528/48 = 0.011, Cl- 0.782/35.5 = 0.022

Ti- 0.011/0.011 , Cl- 0.022/0.011

Ti- 1, Cl-2

Hence the required empirical formula is TiCl2

Answer:

I think it's a sulphate ion, because when you add hydrochloric acid to it it produces bubbles and when you add barium chloride it then produces a white precipitate.its formula is SO4

I hope this helps

Defined as the negative logarithm of the concentration of OH-​
Marat540 [252]

Answer:

As with the hydrogen-ion concentration, the concentration of the hydroxide ion can be expressed logarithmically by the pOH. The pOH of a solution is the negative logarithm of the hydroxide-ion concentration. pOH=−log[OH−] The pH of a solution can be related to the pOH.

Water is the universal solvent and we have seen how salts, like NaCl, dissolve in water. Many other molecules dissolve in water
Advocard [28]

Answer:

Explanation:

Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.

egoroff_w [7]
Cumulene is an alkene hydrocarbon that has two or three double bonds. It is also known as allene. The simplest cumulene is butatriene. It is a rigid hydrocarbon due to the presence of double bonds.

Answer: The orbital that overlap are p/p overlap, s/sp2 overlap, sp/sp2 overlap and sp/sp orbital.
