The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
The number of liters produced when 126g of glucose is completely reacted with O2 is calculated as follows
find the moles of C6H12O6 used that is moles = mass /molar mass
= 126g /180 g/mol = 0.7 moles
from the equation
C6H12O6 +6O2 = 6CO2 +6 H2O
the reacting ratio of C6H12O6 to Co2 is 1:6 therefore the moles of CO2 = 0.7 x6/1= 4.2 moles
At STP 1 moles of a gas = 22.4 L
what about 4.2 L = how many liters
cross multipication
= (4.2moles x 22 .4 L)/ 1mole = 94.1 L
<u>Answer</u>:
"weathering breaks rocks into minerals and plants die and decay" must occur to form soil
<u>Explanation</u>:
For the formation of the soil two process are mandatory and they are erosion as well as weathering. The weathering takes place near the surface of the soil, which can occur due to various physical and chemical processes. Being an important part of soil development. It may occur rapidly or can be a slow process for decades. Water and air helps in weathering. The transport is generally by wind or with the help of flow of water, ice, etc

Answer:
Oxygen
Explanation:
<em>Oxygen. </em>Based on octet rule (An empirical rule that refers to the tendency of atoms to prefer to have eight electrons in the valence shell giving the same electronic configuration of a noble gas), the Sulfur and oxygen need two electrons to complete eight electrons in its valence shell, giving, in this way, the same electronic configuration as Ne and Ar, respectively.
I hope it helps!
