Answer:
It is because water molecules in the air condensed on to the container of the drink.
Explanation:
The way this works is the water molecules outside are hot and in the gas state, so when they come into contact with the cold side of the container they lose energy due to heat transfer between the molecules and the container, becoming a liquid on the side of the drink.
Answer:
Heat of vaporization: 250.580 kJ/mol. Number of Protons/Electrons: 47. Number of neutrons: 61. Classification: Transition Metal.
Number of Protons/Electrons: 47
Number of neutrons: 61
Classification: Transition Metal
Number of shells: 5
Explanation:
add 47 to 61 and its 108! hope its right! have a great day!
Iron-55 (55Fe) is a radioactive isotope of iron with a nucleus containing 26 protons and 29 neutrons.
THE COMPLETE QUESTION IS:
Determine whether each cation is acidic or pH-neutral. For those cations that are acidic, write an equation that shows how the cation acts as an acid . a. NH+4 b. Na+ c. Co3+ d. CH2NH+3
Answer:
<em>a. Acidic</em>
<em>b. neutral</em>
<em>c. Acidic</em>
<em>d. Acidic</em>
Explanation:
a. NH4+ + H2O <==> NH3 + H3O+ (NH4+ is a conjugate acid of a weak base. Therefore it is acidic)
b. Neutral. Na+ is a cation of a strong base. Therefore it's pH is neutral.
c. Co(H2O)6³+ + H2O <==>CoH2O5(OH)²+ + H3O+
(Therefore Co+ is a weak acid since hydronium ion is formed.)
d. CH2NH3+ is a conjugate acid of a weak base. Therefore it is acidic.
