x + y = 100
0.10x + 0.45 y =25
eliminate
x + y = 100
x + 4.5 y = 250
-3.5 y = -150
y = 42.85
x = 57.15
hope this helps
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
Hello!
GAS SOLUBILITY INCREASES:
• O2 in the blood of a person who is in a hyoerbaric chamber.
• The partial pressure of an anesthetic gas is increased.
• The temperature is decreased.
GAS SOLUBILITY DECREASES:
• CO2 In a can of soda as it warms to room temperature.
• The pressure of a gas over a solvent is decreased.
I really hope this helped you! :)
Answer: 20 mg Te-99 remains after 12 hours.
Explanation: N(t) = N(0)*(1/2)^(t/t1/2)
N(t) = (80 mg)*(0.5)^(12/6)
N(t) = 20 mg remains after 12 hours
Answer:
the type of change in which the chemical composition of an element changes is called chemical change
the best example is the formation of H2O. Since Hydrogen is an inflammable gas and oxygen is consumed by fire to keep burning, but their product - H2O is used to extinguish oxygen
