The answer is 0.25 M
Use the equation C1V1=C2V2
(.5)(100)=x(200)
x=0.25
Answer:
1.91 atm
Explanation:
Step 1: Calculate Henry's constant (k)
A gas has a solubility (C) of 2.45 g/L at a pressure (P) of 0.750 atm. These two variables are related to each other through Henry's law.
C = k × P
K = C/P
K = (2.45 g/L)/0.750 atm = 3.27 g/L.atm
Step 2: Calculate the pressure required to produce an aqueous solution containing 6.25 g/L of this gas at constant temperature.
We have C = 6.25 g/L and k = 3.27 g/L.atm. The required pressure is:
C = k × P
P = C/k
P = (6.25 g/L)/(3.27 g/L.atm) = 1.91 atm
A chemical change is a change that results in new chemicals (the reactants underwent a chemical change which resulted in new products).
an example of a chemical change is the burning of paper. An example of something that is not a chemical change is the melting of ice.
Answer is: <span>j. double-replacement.
</span>Double displacement
reactions - cations and anions of the two reactants switch
places and form two new compounds.
Neutralization<span>is
is reaction in which an acid and a base react quantitatively with each other. In this reaction, there are no acids and bases, only salts.
</span><span>Synthesis
is reaction of two or more substances combining to make a more complex
substance. In this example, there is more complex substance in products.
</span>Oxidation-reduction reactions - <span>change in the oxidation number between the reactants and the products. In this example there is no change in oxidation number of elements.</span>
