Answer:

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). ... Cameras on satellites can be used to make images of temperature changes in the oceans.

2.The answer is Land Area. If you know the distance and scale at which the image was captured, than one pixel of the image is equal to an X amount of area. The land area is represented as one pixel in an image called Resolution.

3.A pixel is the smallest picture element addressable on a picture, it is a specific location, and at that location associated with that location, is color, intensity

a.mph (miles per hour), mph. knots, knots. m/s (meters per second), m/s. ft/s (feet per second), ft/s. km/h (kilometers per hour), km/h ...

Explanation:

7 kph 4.35 mph

8 kph 4.97 mph

9 kph 5.59 mph

10 kph

The second-order decomposition of NO2 has a rate constant of 0.255 M-15-1. How much NO2 decomposes in 4.00 s if the initial conc
S_A_V [24]

Answer:

Option D, Concentration of NO2 decomposes after 4.00 s = 0.77 mol

Explanation:

rate\;constant = 0.255\;M^{-1}s{-1}

Time (t) = 4.00\;s

Initial concentration of NO2 = 1.33 M

Integrated law for second order reaction:

\frac{1}{[A]}=\frac{1}{[A]_0} =kt

Where, [A] = Concentration after time, t

[A]0 = Intitial concentration, k = rate constant, t = time

On substituting values in the above

\frac{1}{[A]}=\frac{1}{1.33} =0.255 \times 4.00

\frac{1}{[A]} =1.772

[A] = 0.5644 M

Concentration of NO2 decomposes after 4.00 s = 1.33 - 0.5644 = 0.7656 M

No. of mole = Molarity * volume

                    = 0.7656 * 1

                    = 0.7656 mol 0r 0.77 mol

What is the difference between the compounds Fe2O3 and FeO? Why are they not both called simply iron oxide?
Kitty [74]
There is a big different. Iron (Fe) is a transitional metal. these type of metals are known to have different "versions" of the same element with different charges. Iron has two ions, Fe+2 and Fe+3. so the molecular formula varies depending on which iron ion you have. 

Oxygen is a nonmetal and it will always have the same charge, -2. 

remember that when you put two atoms together, you "cross" the charges and put them as a suffix. I have attached a picture as a visual aid of how to do this.

so, if you put together Fe+2 and oxygen you can get Fe2O2, which simplifies to FeO since the have the same suffix.this compound is called Iron (II) oxide because the iron is the one with charge +2.

so, if you put together Fe+3 and oxygen you can get Fe2O3. this compound is called Iron (III) oxide because the iron is the one with charge +3.

4.<br> How does a positive ion form?
MakcuM [25]

Answer: Metal atoms lose electrons from their outer shell when they form ions: the ions formed are positive, because they have more protons than electrons.
