Question

M(C6H6)-7,8 V(H2)-?m(С6Н12)-?C6H6+3H2=C6H12​

Answer 1

Ответ:

Объяснение:

 7,8 г              Х л                        Х г

C6H6     +      3H2     ->            C6H12

n=1 моль           n=3 моль           n=1 моль

М=78 г/моль   Vm=22,4/моль   М=84 г/моль

m=78 г             V = 67,2 л            m=84 г

7,8 г   С6Н6    -    Х л   Н2

78 г   С6Н6    -   67,2 л  Н2

V(H2) = 7,8 * 67,2 / 78 = 6,72 л

7,8 г  С6Н6   -   Х г   С6Н12

78 г   С6Н6  -   84 г   С6Н12

m(C6H12) = 7,8 * 84 / 78 = 8,4 г

Answer 2

The chemical equation you provided is:

C6H6 + 3H2 = C6H12

This equation represents the reaction where benzene (C6H6) reacts with hydrogen gas (H2) to form cyclohexane (C6H12).

To balance the equation, we need to ensure that there is an equal number of atoms on both sides of the equation. Here's how we can balance it:

C6H6 + 3H2 = C6H12

To balance the carbon (C) atoms, we have 6 carbons on both sides.

To balance the hydrogen (H) atoms, we have 6 hydrogens in the benzene on the left side, and 12 hydrogens in the cyclohexane on the right side. Therefore, we need to add 6 hydrogens to the left side to balance it:

C6H6 + 3H2 = C6H12 + 6H2

Now the equation is balanced, and we have 6 moles of benzene (C6H6) reacting with 3 moles of hydrogen gas (H2) to produce 1 mole of cyclohexane (C6H12) and 6 moles of hydrogen gas (H2).
