Answer:

Metal oxides are compounds composed of metal ions and oxide ions. Nonmetal oxides are compounds composed of nonmetal atoms and oxygen atoms. The main difference between metal oxides and non metal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.

Answer:

Metals react with oxygen to form metallic oxide while Nonmetals react with oxygen to form non-metallic oxide. metallic oxides are basic in nature while Nonmetallic oxides are acidic in nature.

Metal oxides are compounds composed of metal ions and oxide ions. Nonmetal oxides are compounds composed of nonmetal atoms and oxygen atoms. The main difference between metal oxides and non-metal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.

METALS:

Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydrides.

--------------------------------------------------------------------

NON-METALS:
Non-metals react with hydrogen to form stable, covalent hydrides.

How many grams of sodium are in 0.820 moles of na2so4?

s344n2d4d5 [400]

the molar mass of a compound is the sum of the products of the atomic masses by the number of atoms of the element.
molar mass of Na₂SO₄ is - 142 g/mol.
1 mol of Na₂SO₄ has a mass of 142 g.
In 1 mol of Na₂SO₄ the mass of Na is 23 g/mol x 2 = 46 g.

Mass of Na in 1 mol of Na₂SO₄ is - 46 g

mass of Na in 0.820 mol of Na₂SO₄ - 46 g /1 mol x 0.820 mol = 37.72 g.
mass of Na is 37.72 g

Out of 500 silicon atoms: 460 are si-28, which has a mass of 27.98 amu 25 are si-29, which has a mass of 28.98 amu and 15 are si

liberstina [14]

Answer;

=28.09 amu

Explanation;

In this problem, they did not give us the percentages. However, since we know the number of atoms, we can easily calculate the percentages. For example:

(460 X 100)/500 = 92%

If we do this for all three isotopes,

(460 × 25)/500 = 5 %

(460 × 15) /500 = 3%

-We get 92%, 5%, and 3%. (We'll assume these are absolute numbers for determining our significant figures).

Now the problem is just like the previous one. First convert the percentages into decimals. Then multiply those decimals by the masses and add. Here's the solution:

= (0.92) X (27.98 amu) + (0.05) X (28.98 amu) + (0.03) X (29.97 amu)

= 25.74 amu + 1.449 amu + 0.8991 amu

= 28.09 amu

Define acid and base according to lewis theory, arrhenius theory and lawn theory

WITCHER [35]

Answer:

Three principal theories about acid-base are,

1. Arrhenius theory

2. Bronsted-Lowry theory

3. Lux-Flood definition

4. Lewis theory

5. Usanovich definition

1. According to the Arrhenius, acids give up hydrogen ion in aqueous medium and a base give up hydroxyl ion in its aqueous medium. Examples are aqueous solution of HCl, CH3COOH, PhCOOH, and H2SO4. These give up H+ in an aqueous medium. Aqueous solutions of NaOH, Ca (OH)2 are Arrhenius bases.

Arrhenius theory has some limitations. This theory cannot explain the acidic nature of BF3 or basic behavior of NH3. This theory fails to give any explanation about acidity and basicity which does not produce H+ and OH- in their aqueous solutions.

2. According to the Bronsted-Lowry, an acid releases proton and a base accepts proton. NH3 accepts proton and forms ammonium ion, so ammonia acts as a base.

But this theory also has limitations. According to this theory acidic behavior of BF3 still cannot be explained.

3. Lux-Flood describes the acid-base theories based on oxide ion transformation. It gives clear explanation for acid-bases theories of non-protonic system. According to them, a base will donate the oxygen atom and an acid will accept oxygen atom.

4. According to the Lewis theory, acids are those substances which accept electron pair and base are those substances which donates electron pairs. Lewis theory can explain the acidic nature of BF3. In BF3, B is two electrons short to fulfil its octet. So it can accept a pair of electrons from an electron donating substituent. So it is an electron pair acceptor compound and acts as an acid.

Substances which have π electrons can donate electron pair to an electron deficient substance and acts as a base. Ethylene and acetylene is Lewis bases. AlCl3, PCl3 are Lewis acids.

5. According Usanovich, an acid is some chemical species which would react with bases and yields cations or accepts anions or electrons. A base is some chemical species which would react with acids, yield anions or electrons or combine with cations.
