Examination reveals that 180.2 g/mol of glucose contains 72.1 grams of carbon, 96 g/mol of oxygen and the remainder is hydrogen. How many g of hydrogen are there in 55.5 g of glucose?

Answers

Answer 1

Mass of Hydrogen = 3.7 g

Further explanation  

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

180.2 g/mol of glucose-C₆H₁₂O₆ contains 72.1 grams of carbon, 96 g/mol of oxygen and the remainder is hydrogen

Remainder Hydrogen :

[tex]\tt 180-(72.1+96)=11.9~g/mol[/tex]

% mass of Hidrogen in Gllucose :

[tex]\tt \dfrac{11.9}{180}\times 100\%=6.61\%[/tex]

So mass of Hydrogen in 55.5 g Glucose :

[tex]\tt 6.61\%\times 55.5~g=3.7~g[/tex]

Which of the following best represents and explains the formula for a compound made from fluorine and hydrogen?

A. HF, because both fluorine and hydrogen are capable of forming only one ionic bond.

B. HF, because both fluorine and hydrogen are capable of forming only one covalent bond.

C. H2F, because fluorine is short of two electrons, and hydrogen is short of one electron.

D. H2F, because fluorine is capable of forming one, and hydrogen is capable of forming two covalent bonds.

Thank you ​

Answers

The answer is B

HF, because both fluorine and hydrogen are capable of forming only one covalent bond.

The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent  bond is weaker than ionic bond.

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.

The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond.

Therefore, the correct option is option B.

how do you determine valence electrons of a metal? A non Metal?

Answers

Answer:

Check the electronic configuration of elements.

Explanation:

Valence electrons are the elwctrons present in the outermost shell of any element.

For example,

Electronic Configuration of Sodium = 2,8,1

Here , Sodium has 1 valence electrons.

Valency of an element is the total no. of electrons to be gained/losed in order to achieve duplet/octate state.

For example,

Electronic configuration of Sodium = 2,8,1

Sodium can achieve octate state either by losing 1 electron or gaining 7 electrons. But losing 1 electron is eay than gaining 7 electrons. So Valency of Sodium = +1

Metals have 1 or 2 or 3 valence electrons.

Non metals have 4 or 5 or 6 or 7 valence electrons.

Noble gases tend to stay in duplet/octate state i.e they have 2 or 8 valence electrons.

Answer: More than one atom of the same type chemically joined together

Explanation:

An atom is the smallest unit of any matter which may or may not have independent existence. Example: Argon (Ar) is an element which exist as Ar atom only.

Molecule is the smallest unit of any matter which always have independent existence. For example: Hydrogen (H) is an element which can exist in nature as [tex]H_2[/tex] molecule only.

Atoms of different elements chemically joined together is called as a compound. Example: [tex]H_2O[/tex] is a compound formed by chemical combination of hydrogen (H) and oxygen (O) atom.

Which chemical equation represents a decomposition reaction?
O A. 2C2H6 + 702 + 4CO2 + 6H20
O B. AgNO3 + LiCl → AgCl + LINO3
O C. Ca + MgS → CaS + Mg
O D. 2H20 2H2 + O2

Answers

Decomposition reaction D. 2H20⇒ 2H2 + O2

Further explanation

Every chemical reaction involves a compound consisting of reactants and products  

Reactants are compounds that react and form new compounds called products

There are several forms of reactions that can occur, including single replacement, double replacement, synthesis, decomposition, etc.

A. 2C2H6 + 702 ⇒ 4CO2 + 6H20

Combustion : reaction of Hydrocarbon and Oxygen

B. AgNO3 + LiCl → AgCl + LINO3

Double replacement : there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

C. Ca + MgS → CaS + Mg

Single replacement :one element replaces the other elements of a compound to produce new elements and compounds

D. 2H20⇒ 2H2 + O2

Decomposition : One compound breaks down into 2 components

Decomposition, often known as rot, is the breakdown of dead organic matter into more basic organic or inorganic components such as carbon dioxide, water, simple sugars, and mineral salts. Here among the given options, the decomposition reaction is 2H₂O→ 2H₂ + O₂. The correct option is D.

Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input. For instance, the thermal breakdown of potassium chlorate (KClO₃) is a typical technique used in laboratories to generate oxygen gas.

Soft drink carbonic acid breaks down to release carbon dioxide gas. As water breaks down, gases like hydrogen and oxygen are released. Food digestion is a response to breakdown.

Thus the correct option is D.

She remembered that chemical equations can summarize what happens in a chemical reaction. What is the name of the two parts found on the left side of the equation below? 4 Fe + 3O2 → 2Fe2O3 A. products B. reactants C. scientific notation D. synthesis

Answers

Answer:

The name of the two parts found on the left side of the equation is reactants.

Explanation:

Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.

Reactants ⇒ Products

Then, the name of the two parts found on the left side of the equation is reactants.
