4. Describe the movement of the water molecules at cold temperatures.
kenny6666 [7]

Answer:

Point out to students that molecules of hot water are moving faster and are slightly further apart. The molecules of cold water are moving slower and are a little closer together. If students do not notice a difference, move the slider all the way to the left again and then quickly to the right.

2. How do molecules move in cold water?

Compare the speed of molecules in hot water compared to molecules in cold water? Water molecules move faster in hot water and slower in cold water. water molecules in cold, room temperature, and hot water. most of the liquid.

When copper (I) oxide dissolves in dilute sulfuric acid, copper (II) sulfate and copper are produced
const2013 [10]

Answer:

Cu2O + H2SO4 ——> CuSO4 + Cu + H2O

Cu2O is oxidized and reduced. It lost an electron in CuSO4 for the 2+ charge, but it gained an electron in Cu to go from the 1+ charge to a neutral charge. This is dismutation (aka disproportionation)

An ionic bond would form between which pairs of elements? atomic number 4 and atomic number 18 atomic number 7 and atomic number
weeeeeb [17]

Answer:

atomic number 8 and atomic number 12

Explanation:

atomic number 8 and atomic number 12 , element with the atomic number 8 is oxygen, and the element with atomic number 12 is Magnesium

Magnesium has low ionization energy, hence higher tendency to loose its two outermost electrons to form positive ion.

Oxygen has high electron affinity, hence higher tendency to accept or gain electrons to form negative ion.

The electronegativity difference between the element with atomic number 8 and element with atomic number 12 is greater for the formation of ionic bond
