Identify the effect of increasing acidity on the solubility of the given compounds.

Answers

Answer 1

Answer:

An addition of acid increases the solubility of calcium phosphate because the hydrogen ions can easily dissociate and form salts. And example is from the reaction 3H2SO4 + Ca3(PO4)2 → 2H3PO4 + 3CaSO4. CaSO4 is the salt of sulfuric acid and calcium phosphate.

Answers

The answer is sublimation.

Sublimation is the chemical process whereby a solid turns into a gas without first becoming a liquid.

The word sublimation comes from the Latin word sublimare which means "raised to a higher status."

Examples of sublimation include surface layer of snow and ice turning into steam or fog without melting and dry ice which is the solid form of carbon dioxide which also undergoes sublimation.

The low temperature and sublimation makes dry ice an effective coolant or cooling agent . One of its main advantages is that it has a lower temperature than water ice and also does not leave any residue.

Find the mass of 3.00 mol of acetic acid, C2H4O2.

Answers

Molar mass

C₂H₄O₂ = 60.0 g/mol

n = mass / molar mass

3.00 = mass / 60.0

m = 3.00 * 60.0

m = 180 g of C₂H₄O₂

How many moles of carbon dioxide is produced when 10.4 mol of propane gas is burned in excess oxygen?a. 0.288 mol
b. 3.46 mol
c. 31.2 mol
d. 52.0 mol
just the letter

Answers

The number moles of carbon dioxide 31.2 moles will be produced when 10.4 mol of propane gas is burned in excess oxygen.

What is moles?

A mole would be the amount of a material that includes exactly 6.02214076 × $10^(23)$ of the particular chemical elementary constituents.

It is known that the formula of propane is $C_(3)H_(8)$ .

The chemical reaction of propane.

$C_(3)H_(8)$ + $5O_(2)$ → $3CO_(2) +4H_(2)O$

It can be understand that, the ratio of propone and carbon di-oxide is 1:3.

The moles of propane = 10.4 mol

So, number of moles of $CO_(2)$ = 10.4 mol × 3 =31.2 mol.

Therefore, the number of moles of carbon di-oxide will be 31.2

Hence, the correct answer will be option (C).

The formula of propane is C3H8. The reaction equation is C3H8 + 5O2 = 3CO2 + 4H2O. So the ratio of mol number of propane and CO2 is 1:3. So the CO2 has 10.4*3=31.2 mol. So the answer is c.

How does a lithium cation compare to a lithium atom? The cation is larger. The cation has the same radius. The cation is smaller. The cation has the same charge

Answers

Answer:

The cation is smaller.

Explanation:

Electronic configuration of Lithium atom is as follow,

Li = 1s², 2s¹

while, Electronic configuration of Lithium cation is as follow,

Li⁺ = 1s²

The Lithium Cation is smaller because,

i) Less Energy Levels:

As depicted in electronic configurations, the valence shell of Li atom is 2 while, that of Li cation is 1 as a result the distance of valence electrons and nucleus has decreased resulting in small size.

ii) Less Shielding Effect:

The effect in which the core electrons shield the valence electron from nucleus pull is known as shielding effect. In Li cation there are no core electrons hence, the electrons are more attracted towards proton resulting in small size.

iii) More Nuclear Charge:

In Li atom there are three protons and three electrons so, three protons attract three electrons and the game run some what balance. But, as tone electron is lost in Li Cation, the proton side gets stronger and apply more pull on electrons and made them more closer to the nucleus resulting in size decrease.

The correct statement is: The cation is smaller.

In a neutral lithium atom, there are three electrons surrounding the nucleus, distributed in different energy levels or electron shells. These electrons repel each other due to their negative charges, creating an electron-electron repulsion that tends to spread them out and increase the size of the atom.

When a lithium atom loses one electron to form a cation, it becomes positively charged. This loss of an electron reduces the electron-electron repulsion within the atom. With fewer electrons, the remaining electrons experience a stronger attraction towards the nucleus, since the positive charge of the nucleus is no longer balanced by the negative charge of the lost electron.

As a result, the remaining electrons are drawn closer to the nucleus in the lithium cation. The reduction in electron-electron repulsion and the increased attraction between the electrons and the nucleus cause the cation to have a smaller size compared to the neutral atom.

Hence, the lithium cation (Li⁺) is smaller than the lithium atom (Li)
