Explanation:
option option B is the correct answer of given statement helium-4(He)=2
Answer:
two examples are blood and soapy water.
Explanation:
The answer is A. Aluminum Chloride it does not have the prefix "tri-" since it is ionic.
C. Shape, because increasing pressure has a profound influence on the volume of a gas sample, for example, it pushes the particles closer together; thus gases are considered compressible.
Let P be the product solution, A be the 30% alcohol solution and W be the distilled water.
If we multiply the percentage of alcohol to the volume of the stream, we can obtain the amount of alcohol. Alcohol in the product is the sum of the alcohol in the solution and water.
Vp x 0.25 = 50 x 0.3 + Vw x 0
Vp = 60 gallons of product solution
Volume of product = volume of alcohol sol + vol of water
60 = 50 + Vw
Vw = 10 gallons
10 gallons of water must be added.
