An ice cube is placed on a kitchen counter then heat flows from the counter to the ice, causing the molecules in the counter to move more slowly.
<h3>What is heat flow?</h3>
Heat flow is a process in which heat is transfered from hot body to the cold body.
So, when we place an ice cube to the counter of the kitchen and here ice is a colder body and counter is a warmer body so transfer of heat takes place from counter to the ice cube. As a result of which movement of particles of counter gets slow and of ice increases.
Hence in the given situation heat flows from the counter to the ice, causing the molecules in the counter to move more slowly.

Answer:
H2 + I2 --> 2HI
Explanation:
The two reactants are diatomic molecules because they contain two atoms of the same element. Therefore, they would need to have a subscript of "2" next to their symbols.
When balancing an equation, you want the same amount and type of atoms on both sides. By adding a coefficient of "2" in front of the product, two H's and two I's are now on both sides.
In diamond, The arrangement of carbon atoms follows a tetrahedral shape. Each carbon is attached to four other carbon
atoms, forming strong covalent bonds.This arrangement of the diamond is very durable and rigidity, that's why is necessary so many energy to break it.
On the other hand, graphite, has a different geometric
arrangement. the carbon atoms are arranged in 2D sheets and each carbon is linked to three other carbon atoms, forming
hexagonal rings that are easily broken.
Answer:
Really sorry I don't know answer
Answer:
saturated solution because it can only dissolve upto fixed temperature
