Answer:
2S +3O2 =2SO3
Explanation:
2 at the front of sulphur is to equalize the 2 put in SO3.
Answer:
The sun is not yellow.
Explanation:
sun can look yellow or red whenever we see the sunlight at sunrise or sunset, when it becomes low on the horizon. That's only how the wavelengths of the low frequency (green , blue, magenta) are dispersed across the planet's crust, just as the tiny waves are distributed along the sea by huge rocks.
The solubility product constant, Ksp, is calculated by the product of the concentration of the dissociated ions raise to the stoichiometric coefficient of each ion. We calculate what is asked in this problem as follows:
Ag2SO4 = 2Ag^+ + (SO4)^2-
Ksp = [Ag^+]^2 [SO4^2-]
<span>6.0 x10^-5 = 4x^2 (x) = 4x^3
x = 0.025 M
0.025 mol </span>(SO4)^2- / L ( 1 mol Ag2SO4 / 1 mol (SO4)^2-) (311.799 g / mol ) = 7.69 g Ag2SO4 / L solution
The age of the remnants is calculated as 3807 years.
<h3>What is the half life?</h3>
The half life is the time taken for only half of the number of the radioactive atoms to remain.
Half life of carbon - 14 = 5730 years.
Initial count rate = 8.0 counts per minute per gram
Count rate at time t = 12.7 counts per minute per gram of carbon
Since;
0.693/t1/2 =2.303/t log (N/No)
0.693/5730 = 2.303/t log (12.7/8)
1.21 * 10^-4 = 2.303/t * 0.2
t = 2.303 * 0.2/1.21 * 10^-4
t = 0.4606/1.21 * 10^-4
t = 3807 years

<span>When cyclohexanol is dehydrated using various means it creates a new hydrocarbon. This new hydrocarbon is called cyclohexene. Cyclohexene is a liquid which has no color, yet has a very strong smell to it. It is used in common industrial processes, but is also considered somewhat unstable due to it's tendency to form peroxides when exposed to light.</span>
