C₂H₇ is a covalent compound

N0₄ will be name nitrogen(viii) oxide

MgCl₂ will be named magnesium chloride.

<h3>What are covalent compounds? </h3>

Covalent compounds are compounds which are formed when two electronegative atoms combine together by a sharing of electrons between them.

Covalent compound molecules are usually formed from a combination of non-metals.

The C₂H₇ is a covalent radical formed from the addition of a hydrogen ions to the covalent compound C₂H₆

<h3>What would you name NO₄?</h3>

The name given to a compound depends on the oxidation number of the component elements.

The oxidation number of oxygen is -2.

Since there are 4 atoms of oxygen, the total negative charge is -8.

Nitrogen will have to exist in the +8 state in order to give a neutral compounds.

Therefore, the name given to the compound will be nitrogen (viii) oxide.

<h3>What would you name MgCl₂? </h3>

Magnesium chloride, MgCl₂ is an ionic compound formed from the ionic bond between chlorine and magnesium.

Magnesium donates two electrons to two chlorine atoms to form magnesium chloride, MgCl₂.

The fact that HBO2, a reactive compound, was produced rather than the relatively inert B2O3 was a factor in the discontinuation

Reil [10]

Answer:

1027.62 g

Explanation:

For $B_2H_6$ :-

Mass of $B_2H_6$ = 296.1 g

Molar mass of $B_2H_6$ = 27.66 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{296.1\ g}{27.66\ g/mol}$

$Moles\ of\ B_2H_6= 10.705\ mol$

From the balanced reaction:-

$B_2H_6(g) + 3 O2_{(l)}\rightarrow 2 HBO_2_{(g)}+ 2 H_2O_{(l)}$

1 mole of $B_2H_6$ react with 3 moles of oxygen

Thus,

10.705 mole of $B_2H_6$ react with 3*10.705 moles of oxygen

Moles of oxygen = 32.115 moles

Molar mass of oxygen gas = 31.998 g/mol

<u>Mass = Moles * Molar mass = 32.115 * 31.998 g = 1027.62 g</u>

Cellulose could provide an abundant and cheap form of glucose for humans. Why is cellulose not a source of nutrients for humans?

mojhsa [17]

Answer:

Option (c).

Explanation:

Cellulose is one of the most important carbohydrate of the plant that provide structural framework to the plant cells. Cellulose is made of the monomer of the glucose that are linked through the beta glycosidic linkages.

Although cellulose contains large number of glucose but it cannot be used as the nutrient source for humans. Humans and other vertebrates lacks the enzyme cellulase that is required for the digestion of cellulose. Cellulose cannot be broken down in the human body.

Thus, the correct answer is option (c).
