What must happen for heat to be transferred by convection

Marrrta [24]

Answer: The heat transfer by convection requires a solid-fluid interface, a temperature difference between the solid surface and the surrounding fluid and a motion of the fluid. The process of heat transfer by convection would occur when there is a movement of macro-particles of the fluid in space from a region of higher temperature to lower temperature.

What is the full ionic equation for CuCl2 and (NH4)2SO4?

melisa1 [442]

The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is 2(NH4)Cl + CuSO4.

Explanation:

The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is

CuCl2 + (NH4)2SO4 ⇔ 2(NH4)Cl + CuSO4.

Here the left side one's are reactants i.e.,CuCl2 and (NH4)2SO4.

The right siders are products i.e.,(NH4)Cl and CuSO4.

The complete ionic equation is used to include both chemical species as well as spectator ions. It is used to indicate which of the reactants and products in the equation exists primarily as ions in aqueous solution.

It is nothing but a chemical equation in which electrolytes which are soluble in water are formed as dissociated ions.

The above chemical reaction is double displacement reaction.

Which two ions have the same electron configuration?

djverab [1.8K]

Answer: A) Na+ and O2-

Explanation:

To know the electronic configuration, one has to determine the numbers of electrons present in each atom.

Na+ means a sodium atom that has lost one valence electron. A Sodium atom initially has 11 electrons, but having lost an electron making it 10 electrons remaining with electron configuration of 1s2 2s2 2p6.

O2- means oxygen atom that has gained two valence electrons. An oxygen atom initially has 8 electrons, having gained two electrons makes it 10 electrons with electron configuration of 1s2 2s2 2p6. same as Na+

The purpose of gaining or losing electrons is to attain a stable duplet or octet structure.

How many atoms of titanium are there in 0.125 mole of each of the following?a. ilmenite, FeTiO3b. titanium(IV) chloridec. Ti2O3d

Gekata [30.6K]

Answer:

a. 7.528x10²² atoms Ti

b. 7.528x10²² atoms Ti

c. 1.5055x10²³ atoms Ti

d. 2.258x10²³ atoms Ti

Explanation:

Using the molecular formula of the structures, we can determine the moles of titanium in 0.125 moles of each compound. With moles of titanium we can convert these to atoms using Avogadro's number as follows:

a. FeTiO₃: 1 mole of Ti per mole of FeTiO₃.

Moles of Ti are 0.125 moles. Atoms are:

0.125 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>7.528x10²² atoms Ti</h3>

b. Titanium (IV) chloride = TiCl₄: 1 mole of Ti per mole of TiCl₄.

Moles of Ti are 0.125 moles. Atoms are:

0.125 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>7.528x10²² atoms Ti</h3>

c. Ti₂O₃: 2 moles of Ti per mole of Ti₂O₃.

Moles of Ti are 2*0.125 moles = 0.25 moles. Atoms are:

0.25 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>1.5055x10²³ atoms Ti</h3>

a. Ti₃O₅: 3 mole of Ti per mole of Ti₃O₅.

Moles of Ti are 3*0.125 moles = 0.375 moles of Ti. Atoms are:

0.375 moles Ti * (6.022x10²³ atoms / 1 mole) =

<h3>2.258x10²³ atoms Ti</h3>
