1. ice, water
2. hot soup, spoon
3. cell phone, hand
4. ice cream, bowl
5. hair dryer, hair
one has more thermal energy than the other
they both heat up or cool to the same temperature
Taking the compound with the metallic counterpart of highest mass would be the answer. Looking at the periodic table, it is easy to realize that K has the highest mass out of H, Li, K, and Cl. Therefore, the answer is (2) KCl.
The answer is na sodium, bromine
Balancing of the chemical reaction involves keeping the number of atoms of a certain element equal in both sides of the equation. For this item, the balanced chemical equation would be,
N2 + 3H2 --> 2NH3
The numerical coefficients are therefore 1 for N2, 3 for H2, and 2 for NH3. The sum of the numerical coefficients is 6.
<em>Answer: 6</em>
<h3>Answer:</h3><h2>Chemical properties</h2><h3>Explanation:</h3>
By its very definition, a chemical property is one which is exhibited as a result of a chemical reaction. This may happen during or after the reaction. This is because in a chemical reaction there is a transformation in the physical composition of the components and this directly affects its chemical properties.
