Acetylene gas is often used in welding torches because of the very high heat produced when it reacts with oxygen gas, producing
UkoKoshka [18]

<u>Answer:</u> 1.2 moles of carbon dioxide is produced for the given value of oxygen.

<u>Explanation:</u>

The chemical reaction for the combustion of acetylene follows the equation:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

By stoichiometry of the reaction:

5 moles of oxygen produces 4 moles of carbon dioxide.

So, 1.5 moles of oxygen will produce = \frac{4}{5}\times 1.5=1.2mol of carbon dioxide.

Hence, 1.2 moles of carbon dioxide is produced for the given value of oxygen.

Methylcyclopentene reacting with reacting with sulfuric acid and water
dlinn [17]

Answer:

The product is 1-methylcyclopentanol  

Explanation:

The acid-catalyzed hydration of alkenes involves the addition of a water molecule to a C=C double bond.

H₂O + C=C ⟶ H-C-C-OH

An H atom adds to one of the C atoms, and an OH group adds to the other

This reaction follows Markovnikov’s rule — the H adds to the C atom that has more hydrogen atoms, and the OH adds to the more substituted carbon.

The steps of the mechanism are:

  1. The aqueous sulfuric acid generates hydronium ions
  2. The nucleophilic π electrons attack an H atom  on the hydronium ion, forming a carbocation on the more substituted C atom.
  3. The lone pair electrons on a water molecule attack the carbocation , forming an oxonium ion.
  4. Another water molecule removes the extra proton.

The product is the alcohol with the OH group on the more substituted carbon — 1-methylcyclopentanol.

What happens when an ice cube melts in a glass of water?
morpeh [17]

Answer:

the water is warmer in temperature than the ice cube

Explanation:

the cube wouldn't melt if the water was colder or equally cold (eventually the water would equalize to the room temp) but for a while the water would have to be colder than the cube for the ice cube to stay in a solidified form

What is the mass of copper that increases its temperature by 285 degrees celsius when 186,000 j of energy is applied?
Llana [10]
From reliable sources in the web, it may be searched that the specific heat of copper is approximately equal to 0.385 J/gC. The amount of heat that is required to raise a certain amount by certain number of degrees is given in the equation,
                              H = mcpdT
where H is heat, m is mass, cp is specific heat, and dT is temperature difference. Substituting the known values,
                           186,000 J = (m)(0.385 J/gC)(285C) 
                                     m = 1695.15 g
