The answer should be its kinetic energy increases.
The kinetic energy of a particle means how fast they move, the faster they move, the more kenetic energy they have. In addition, when it moves faster and have more kenetic energy, their temperature becomes higher too.
Therefore, the answer is the first one.
Answer:
Some of liquid to liquid solutions examples are
milk+water solution buttermilk+water solution

petrol+water
mercury+water
Answer:
of different elements with different electronegativities
Explanation:
A molecule containing two atoms "of different elements with different electronegativities"
A polar covalent bond exists when two different atoms (non-metals) with different electronegativities are able to share their electrons in a covalent bond.
Some examples of polar covalent bonds are seen in:
1. Ammonia(NH3): The polar covalent bonds exists between the nitrogen and hydrogen atoms.
2. Water(H2O): The polar covalent bond exists between hydrogen and oxygen. The oxygen molecule has a net negative charge while the hydrogen atoms have a net positive charge.
Determine the mass of each of the following amounts. a. 1.366 mol of
NH3
, b. 0.120 mol of glucose,
C6H12O6
, c. 6.94 mol barium chloride,
BaCl2
, d. 0.005 mol of propane,
C3H8
Answer:
About 3.5 kJ.
Explanation:
Recall the heat transfer equation:
Where <em>q</em> is the heat; <em>m</em> is the mass of the substance; <em>C</em> is its specific heat; and Δ<em>T</em> is the change in temperature.
The given specific heat of iron is 462 J/kg -°C.
Substitute and evaluate. Ensure correct units:
Therefore, the block of iron absorbed about 3.5 kJ of heat.
