Answer: hydrogen bonding

Explanation:

Ionic bond is formed by the transfer of electrons between metals and non metals.

Covalent bond is formed by sharing of electrons between two non metals.

Hydrogen bond is the bond formed between hydrogen and an electronegative atom such as fluorine, oxygen and nitrogen.

Water molecules are bonded by strong hydrogen bonding between the hydrogen atom and the electronegative oxygen atom and thus are bonded by cohesive forces of hydrogen bonds.

Each water molecule consists of two atoms of the element hydrogen joined to one atom of the element oxygen. An interesting property of water is the ability of its molecules to “stick together.” This occurs because one side of each water molecule is slightly negative and the other side is slightly positive. The positive portion of a water molecule is attracted to the negative portion of an adjacent water molecule. As a result, water molecules are called polar molecules. They attract other water molecules like little magnets. It is most likely ionic bonding but between hydrogen and oxygen it is covalent.

Which hydrocarbon is saturated?<br> (1) propene (3) butene(2) ethyne (4) heptane
MAXImum [283]
The answer is (4) heptane. Saturated hydrocarbon means that there is no double bonds between the carbon atoms. For propene and butene, there is double bond. For ethyne, there is triple bond.

How many grams of H2O will be produced if 750. grams of Fe are produced?
aleksandr82 [10.1K]

Answer:

\boxed{\small \sf \: Mass \:  of  \: H_2O =322.2 \: grams}

Explanation:

<em>Given:</em>

Mass of ferous (Fe) produced = 750 gram.

<em>To find:</em>

Mass of water produced= ?

<em>Solution:</em>

<em>Molar mass of Fe is 55.84 gram/</em><em>mol</em>

Let's find out the number of moles of ferous produced.

\small \sf Number  \: of  \: moles  =  \frac{Given  \: mass \:  of \:  substance }{Molar \:  mass \:  of \:  substance}

Substituting the given data in above formula.

\small \sf Number  \: of  \: moles  =   \frac{750}{55.84}

\boxed{\small \sf Number  \: of  \: moles \: of \: Fe= 13.43 \: moles}

Now the given reaction is,

Fe_3O_4 + 4H_2  \rightarrow 3Fe + 4H_2O

  • For every 3 mole of production of Fe, 4 mole of waters are produced.
  • let for 13.43 moles of Fe x moles of H2O will be produced.

now calculate the number of moles of H2O

\sf \: \frac{3}{4}  =  \frac{13.43}{x}  \\  \sf x =  \frac{13.43 \times 4}{3}   \\  \sf x = 17.90 \: moles

\small \boxed{\sf number \: of \: moles \: of  \: H_2O= 17.90 \: moles}

mass of one mole of H2O is 18 gram, so we can calculate mass of 17.90 moles.

\small \sf \: Mass \:  of  \: H_2O = 17.90 \times 18 \\    \boxed{\small \sf \: Mass \:  of  \: H_2O =322.2 \: grams}

How many atm are in 1,520 mmHg?
Brums [2.3K]
In 1 atm there is 760 mmHG, so if you divide 1,520 by 760 you get a total of 2 atm. So the answer is 2 atm in 1520 mmHg.
