Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
The answer would be About 3.857yd3
Answer:
The reason for the suspicion was because the manner in which iodine reacted chemically as well as its other chemical properties, indicated that it belonged in the same group as chlorine and bromine, while the much heavier tellurium should be placed in the previous group
The suspicion was proved to be correct when the atomic number of tellurium was found to be 52 and that of iodine was found to be 53 by later scientists
Explanation:
Answer:
Alkaline earth metals
Explanation:
Group 2 has 2 valence electrons that they lose when being ionized, thus making their charge 2+.
Answer:
Ideal ,P=49.52 atm
Real ,P=47.62 atm
Explanation:
Given that
n= 1 mol
V= 0.5 L
T= 29 ∘C = 29 +273 K
T= 302 K
For ideal gas
P V = n R T
P x 0.5 = 1 x 0.0821 x 302
P=49.52 atm
For real gas
Now by putting the values
P=47.62 atm
