Answer:
If the ambient temperature around a piece of ice increases, the temperature of the ice will increase as well. However, this steady increase in temperature stops as soon as the ice reaches its melting point. At this point, the ice undergoes a change of state and turns into liquid water, and its temperature won't change until all of it has melted. You can test this with a simple experiment. Leave a cup of ice cubes in a hot car and monitor the temperature with a thermometer. You'll find that the icy water remains at a frosty 32 degrees Fahrenheit (0 degrees Celsius) until all of it has melted. When that happens, you'll notice a quick temperature rise as the water continues to absorb heat from the inside of the car.
Yes
Explanation:
Valence electrons on the periodic table of elements shows a repeating or periodic pattern. There is a noticeable pattern that can be deduced from the valence electrons in the orbitals of atoms.
Valence electrons are the electrons in the outermost shell of an element
The periodic table arranges elements based on their atomic numbers. This number denotes the number of protons or electrons an atom contains.
- The table is divided into groups which are the vertical columns into which elements are classified.
- The horizontal rows are called periods.
- A period begins with one valence electron and ends with an atom having complete outer shell structure of an inert gas.
- Down a group the valence electron is the same. The group number denotes the number of valence electrons in a group. Group 1 has just one valence electron in their outermost shell.

Answer:
1.27006 kg
Explanation:
1 lb is equal to 0.907185 kg
We have been given the OH⁻ ion concentration, we can calculate the pOH concentration.
pOH = -log [OH⁻]
pOH = - log (5.5 x 10⁻⁵ M)
pOH = 4.26
we can then calculate the pH value
pH + pOH = 14
pH = 14 - 4.26
pH = 9.74
since pH > 7 the solution is basic.
by knowing the pH value, we can calculate the H₃O⁺ concentration
pH = - log[H₃O⁺]
[H₃O⁺] = antilog (-pH) = antilog (-9.74)
[H₃O⁺] = 1.82 x 10⁻¹⁰ M
