The more substance you have, the slower the temperature change.

Remember that the slower the temperature changes, the amount of heat is the same. So basically the amount of substance is what determines how much heat there is available for the temperature to change.After that you calculate.

When nitrogen dioxide gas dissolves in water, an aqueous solution containing dissolved nitric acid and nitrogen monoxide forms.
xeze [42]

Answer:

1. Based on the given question, 138.03 grams of NO₂ is reacting completely with 18.02 grams of H2O. However, in case when 359 grams of NO₂ is used then the grams of water consumed in the reaction will be,  

= 359 × 18.02 / 138.03 = 46.87 grams of water.  

2. As mentioned in the given case 138.03 grams of NO₂ generates 126.04 grams of HNO₃. Therefore, 359 grams of NO₂ will produce,  

= 359 × 126.04 / 138.03  

= 327.81 grams of HNO₃.  

3. Based on the given question, 138.04 grams of NO₂ is generating 30.01 grams of NO. Therefore, 359 grams of NO₂ will generate,  

= 359 × 30.01 / 138.04

= 78.04 grams of NO.

What are the different variables of greenhouse gases and how do they affect one another?
Marysya12 [62]
Greenhouse gases absorb and emit some of the outgoing energy radiated from Earth's surface, causing that heat to be retained in the lower atmosphere. As explained above, some greenhouse gases remain in the atmosphere for decades or even centuries, and therefore can affect Earth's energy balance over a long period.

Predict how decreasing the volume of the container used for the reaxtion below affect the initial rate of the reaction and expla
77julia77 [94]
Decreasing the volume increases the pressure, therefore due to Le Chatelier's principle, we can see that more HI2 will be formed as 2 molecules combine into 1 and that conserves space which in turn lowers the pressure.
