Answer:

$N_2(g)+2O_2(g)\rightarrow N_2O_4(g)$

Explanation:

Hello,

In this case, considering the required product which is dinitrogen tetroxide whose molecular formula is N₂O₄, by considering its formation reaction which is starting by both gaseous nitrogen and oxygen as shown below:

$N_2(g)+O_2(g)\rightarrow N_2O_4(g)$

Nevertheless, it should be balance since four oxygen atoms are present at the right side, thus, we obtain:

$N_2(g)+2O_2(g)\rightarrow N_2O_4(g)$

Best regards.

Statement:

The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.

Explanation:

Problem 1

The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.

Reasons:

Using the mass pieces and the cup to find the weight of the orange is wrong approach.

He can easily place the orange on the balance and read off the weight.

Centimeters is a unit of length. What length is he measuring and recording?

The unit of weight is in newtons(N).

Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.

Problem 2

Rewriting to paragraph to correct the errors:

The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.

A sample of propane (C3H8) has a mass of 0. 47 g. The sample is burned in a bomb calorimeter that has a mass of 1. 350 kg and a

Nady [450]

The amount of heat released by the sample has been 22.54 kJ. Thus, option C is correct.

The specific heat has been defined as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.

The specific heat has been expressed as:

$q=mc\Delta T$

<h3 /><h3>Computation for the heat absorbed</h3>

The iron and calorimeter are in side the closed system. Thus, the energy released by the sample, has been equivalent to the energy absorbed by the calorimeter.

$q_{released}=q_{absorbed}\\
q_{released}=m_{calorimeter}\;c_{calorimeter}\;\Delta T$

The given mass of calorimeter has been, $m_{calorimeter}=1350\;\rm g$

The specific heat of the calorimeter has been, $c_{calorimeter}=5.82\;\rm J/g^\circ C$

The change in temperature of the calorimeter has been, $\Delta T=2.87^\circ \rm C$

Substituting the values for heat released:

$q_{released}= 1350\;\text g\;\times\;5.82\;\text J/\text g^\circ \text C\;\times\;2.87^\circ \text C\\
q_{released}=22,549.5\;\text J\\
q_{released}}=22.54\;\rm kJ$
