Answer:
Exposure of silver chloride to sunlight for a long duration turns grey due to photolytic decomposition i.e decomposition in the presence of sunlight.
Explanation:
When silver chloride, AgCl is exposed to sunlight for a long time, it will undergo decomposition as the sunlight provides sufficient energy needed to decomposed the salt, AgCl to metallic silver and chlorine gas. This can be seen in the equation below:
2AgCl —> 2Ag + Cl2
Answer:
Binomial Naming System
Explanation:
He was the first to use the system, he used it frequently enough for the system to be accepted and used more often by scientists. He believed that species were unable to be changed.
To find the mass you need to find the weight of a mol of the molecules by adding up the atomic mass.
N = 14.007 g/mol
H = 1.008 g/mol
S = 32.065 g/mol
O = 16 g/mol
2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol
Now you know how much an entire mol weight you multiply it by how much you actually have
0.00456 * 132.143 = 0.603 g
Answer:
5.74 gm
Explanation:
First, use the ideal gas law PV = n RT
to find the number of moles, then multiply by 28 g/ mole
PV = n RT T must be in Kelvin R = 8.314463 L kPa/(K - Mol)
( make sure you use the R with the correct units!!)
182 kPa * 3 L = n (8.314463 ) ( 273.15+47.2)
solve for n = .205 moles
.205 mole * 28 g/mole = 5.74 gm
