Depending on the numbers on the side for the price, it could be A or B; if the numbers go from higher to lower then its A, if it goes from lower to higher then its B
B) chemical bond i believe is the correct answer
Answer:
20.2 °C
Explanation:
When the pressure and number of moles are constant, Charles's law may be used to solve for temperature:
T₁/V₁ = T₂/V₂ >> T₂ = T₁ (V₂/V₁)
Expressions for the volumes can be substituted and simplified:
T₂ = T₁ (V₂/V₁) = T₁ (4/3πr₂³/4/3πr₁³) = T₁ (r₂³/r₁³)
Substituting in values in the equation (where the radius r is half of the diameter) gives:
T₂ = T₁ (r₂³/r₁³) = (19.0°C) x ((51.0cm/2)³/(50.0cm/2)³) = 20.2 °C
Answer:its B
Explanation:
i have done this before! and i got 100 so i hope you got all the other questions right!
Answer:
The correct answer is A.
Explanation:
The acids with hydrogen atoms in them are the ones that dissolve best in water and when they do, they get diluted, raising their pH level by releasing hydrogen ions (H+) into the solutions.
So when acids get dissolved in water, positively charged hydrogen atoms are released.
The answer is A.
I hope this helps.
