Choose The Names Of The Substances For Reactants Of The Equation 2H2 + O2 2H2O

Answers

Answer 1
the reactants are hydrogen and oxygen NOT water, WATER is the product
Answer 2

The names of the substances for the reactants in the chemical equation 2H₂ + O₂ → 2H₂O are; Hydrogen gas (H₂) and Oxygen gas (O₂). Option A and C is correct.

Hydrogen gas (H₂) - This is the molecular form of hydrogen, consisting of two hydrogen atoms bonded together.

Oxygen gas (O₂) - This is the molecular form of oxygen, consisting of two oxygen atoms bonded together.

In a chemical equation, the reactants are the substances that undergo a chemical reaction to form new products. In this case, the reactants are hydrogen gas (H₂) and oxygen gas (O₂). The arrow (→) in the equation represents the direction of the reaction, indicating that hydrogen gas and oxygen gas react to form water (H₂O).

The coefficient 2 in front of H₂ and H₂O indicates that two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The balanced chemical equation shows the stoichiometry of the reaction, indicating the number of molecules of each reactant and product involved in the reaction.

Hence, A. C. is the correct option.

A vapor volume of 1.17 L forms when a sample of liquid acetonitrile, CH3CN, absorbs 1.00 kJ of heat at its normal boiling point (81.6 °C and 1 atm). What is Hvap in kilojoules per mole of CH3CN?​

Answers

The heat of vaporization of CH3CN is obtained from the question as 25 KJ/mol.

We can obtain the number of moles from;

PV = nRT

P = 1 atm

V = 1.17 L

n = ?

R = 0.082 atm LK-1mol-1

T = 81.6 °C + 273 = 354.6 K

n = PV/RT

Substituting values;

n =  1 atm × 1.17 L/0.082 atm LK-1mol-1 × 354.6 K

n = 0.04 moles

Using; q = n·ΔHv

q = Heat absorbed

n = number of moles

Hv  = Heat of vaporization

ΔHv = q/n

ΔHv = 1.00 × 10^3/0.04

ΔHv = 25 KJ/mol

The city council of a small town wanted to add fluoride to their water so that all the residents would have healthier teeth. The mayor had read that ionic compounds must be used to get the fluoride into water. He looked up fluorine-containing compounds and came up with the following list. ​
NaF NF3 SiF4 CaF2 NH4F​

Using academic vocabulary in paragraph form, discuss the following: ​

Explain which compound(s) could produce fluoride ions in the water. In your response, be sure to include: ​
° which of the listed compounds are ionic and which are covalent. ​
° how ionic and covalent compounds are different. ​
° why only ionic compounds would produce fluoride in water.​

Answers

Answer:NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and  NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.

The compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

The ionic compounds are formed by the transfer of electrons between the atoms of the compounds. The ionic bonds are weaker and are easy to dissociate in the aqueous solution.

The covalent compounds are formed by the sharing of electrons between the atoms. Since there is sharing, there has been a strong bond, that has been hard to dissociate.

The Mayor has to release Fluoride in the water, thus ionic compounds are preferred that have the easy release of fluorine.

From the given compounds:

NaF = Ionic compound[tex]\rm NF_3[/tex] = Covalent compound[tex]\rm SiF_4[/tex] = Ionic compound[tex]\rm CaF_2[/tex] =  Ionic compound[tex]\rm NH_4F[/tex] =  Ionic compound

Thus the compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].
