Using the equation 2H2+O2 = 2H2I, if 192 g if oxygen reacts completely, how many grams of hydrogen must react with it

I assume there is a typo in the equation.  It is H2O instead of H2I.

The ratio of H2 and O2 that react with each other is 2:1.  To find out the grams of H2, we need to first find out the moles of O2 and H2.

Moles of O2 = mass of O2/molar mass of O2 = 192g/32g/mol = 6 mol.  Therefore, the moles of H2 = 6mol *2 = 12 mol.

So the mass of H2 that reacts with O2 = moles of H2 * molar mass of H2 = 12 mol * 2 g/mol = 24 g

What best explains the formula unit for a compound made from fluorine and hydrogen?
kirza4 [7]

Answer:

2)HF bcz both fluorine and hydrogen are capable of forming only one covalent bond

Explanation:

flourine is short one electron to become stable while hydrogen has only one electron.Hydrogen cant give out its one electron fully thus it will share its one electron with flourine

When mixtures of gaseous h2 and gaseous cl2 react, a product forms that has the same properties regardless of the relative amoun
lilavasa [31]
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.

The reaction for this problem is:

H₂ + Cl₂ → 2 HCl

1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.

The reaction of 2-methylcyclohexanone with CH3MgBr followed by neutralization gives two alcohols. These two alcohols are
Lilit [14]

The reaction of 2-methylcyclohexanone with CH3MgBr followed by neutralization gives two alcohols. These two alcohols are cyclohexanol and ethanol. This reaction involves Grignard reaction.

<h3>What is Grignard reaction?</h3>
  • Alkyl, allyl, vinyl, or aryl-magnesium halides (the Grignard reagent) are added to a carbonyl group in an aldehyde or ketone to produce the Grignard reaction. The creation of carbon-carbon bonds depends on this process.
  • An organic halide reacts with magnesium, but it does not undergo a Grignard reaction; instead, it produces a Grignard reagent.
  • The carbon bonded to magnesium acts as a nucleophile and targets the electrophilic carbon atom that is present within the polar bond of a carbonyl group because carbon is more electronegative than magnesium.
  • Usually, the Grignard reagent is added to the carbonyl through a six-membered ring transition state.

Which of the answer choices correctly describes two liquids that cannot combine and form a homogeneous mixture?
tia_tia [17]
The term that is being described above is what we call IMMISCIBLE. This means when liquids are immiscible, it cannot be mixed in order to make a homogeneous mixture. When two liquids are mixed, these will eventually form layers. The answer to this is the first option. Hope this helps.
