Answer:

Nitrogen molecules in solid nitrogen would vibrate about fixed positions close together in the regular lattice and have weak intermolecular forces holding the molecules together. However, in nitrogen gas the nitrogen molecules would be traveling in random directions at high speed and far apart.

Consider the following unbalanced equation. N2+ O2=N2O. When the equation is completely balanced using smallest whole numbers, t
77julia77 [94]

Answer:

2

Explanation:

Since you are balancing the equation you need to have equal amounts of each element on each side. Right now there is 2n and 2o on one side, and on the other 2n and 1o. Although the number of n's on each side is equal the number of o's are not. First I balance the number of oxygen's on each below, but doing that made the number of nitrogen's unbalanced. So then I balanced the nitrogens in step 2.

__N2+ __O2 = __N2O

1. __N2+ __O2 =  2 N20

2. 2 N2 + 1 O2 = 2 N2O

The combustion of 44.45 grams of a hydrocarbon gas mixture releases 2,649 kJ of heat. How much energy, in kWh, will the combusti
Naddika [18.5K]

Explanation:

It is given that 44.45 g of hydrocarbon gas produces 2649 kJ or 2649 \times 10^{3} J of heat.

Also here, 1 lb = 453.592 g.

Therefore, amount of energy released by 453.592 g of hydrocarbon gas will be calculated as follows.

              \frac{2649 \times 10^{3} J \times 453.592 g}{44.45 g}

             = 27.03 \times 10^{6} J

It is known that 1 J = 2.778 \times 10^{-7} Kwh.

Hence, 27.03 \times 10^{6} J = 27.03 \times 10^{6} J \times 2.778 \times 10^{-7} Kwh/J

                              = 7.508 Kwh

Thus, we can conclude that the combustion of exactly one pound of this hydrocarbon gas produce 7.508 Kwh energy.
