Answer:

Coefficient in front of the NO in the balanced equation - 4

Explanation:

The unbalanced reaction is shown below as:-

NH_3+O_2\rightarrow NO+H_2O

On the left hand side,  

There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms

On the right hand side,  

There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms

Thus,  

Right side, H_2O must be multiplied by 6 and NO by 4

Left side, O_2 is multiplied by 5 and NH_3 by 4 so to balance the whole reaction.

Thus, the balanced reaction is:-

4NH_3+5O_2\rightarrow 4NO+6H_2O

<u>Coefficient in front of the NO in the balanced equation - 4</u>

If 41grams of water at 24°C absorbs 2208 J of heat energy, what will be the final temperature of the water?
aleksklad [387]
The problem can solved using the heat equation which is expressed as:

H = mCΔT

 where H is the energy absorbed or released, m is the mass of the substance, C is the specific heat capacity, and ΔT is the change in temperature.

2208 J = 41 g x 4.18 J/g·°C x ( T - 24 °C) 
T = 36.88 °C

The solar corona has a temperature of more than a million kelvins; the photosphere has a temperature of only about 6000 K. Why i
kicyunya [14]

Answer & explanation:

Despite the huge difference in temperature between the solar corona and the photosphere, in addition to the fact that the solar corona is the largest and outermost layer of the solar atmosphere (about 13 million kilometers), the photosphere becomes a visible surface region due to to the gases present in it, causing the body to stop being transparent, becoming opaque to light.

However, it is still possible to observe the solar corona in total eclipses, where the opacity to light extends across the sun, facilitating the visibility of the corona and other layers.
