The quality or state of being volcanic.
Answer:
1.2x10⁻⁵M = Concentration of the product released
Explanation:
Lambert-Beer's law states the absorbance of a solution is directly proportional to its concentration. The equation is:
A = E*b*C
<em>Where A is the absotbance of the solution: 0.216</em>
<em>E is the extinction coefficient = 18000M⁻¹cm⁻¹</em>
<em>b is patelength = 1cm</em>
<em>C is concentration of the solution</em>
<em />
Replacing:
0.216 = 18000M⁻¹cm⁻¹*1cm*C
<h3>1.2x10⁻⁵M = Concentration of the product released</h3>
Answer:
Answer in explanation
Explanation:
In the first case, we divide each of the masses by the respective atomic masses:
N =0.615/14 = 0.043928571428571
O = 0.703/16 = 0.0439375
It can be seen here that the values are similar, hence the formula is NO
now let us look at the second data set:
N = 1.27/14 = 0.090714285714286
O = 2.9/16 = 0.18125
We now divide by the smallest
N = 090714285714286/090714285714286 = 1
O = 0.18125/090714285714286 = 2
The formula here is thus NO2.
It can be seen that there are different oxides of nitrogen here which clearly indicates the law of multiple proportion.
Physicalchange. Lighting a match and letting is burn is an example of a chemical change. Chemical reactions cause chemicalchanges. In a chemical reactiontwo or more substances, called the reactants, form different substances called products.
The spontaneous disintegration of a nucleus into a slightly lighter and more <u>radioactive </u>nucleus is accompanied by the emission of particles, electromagnetic radiation, or both.
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei into atomic nuclei to shape greater energetically strong atomic nuclei.
Radioactive decay is a tremendously exoergic, statistically random, first-order system that occurs with a small amount of mass being converted to strength.
Spontaneous disintegration of a radionuclide with the emission of lively particles or radiation, consisting of alpha or beta debris or gamma rays.
