Answer:
The metallic elements have more metallic characteristcis.
Explanation:
- Metallic character is the name given to a set of common properties shared by the metallic elements.
- Metallic luster, high density, high electric and thermal conductivity are some physical properties associated with metallic characters.
- Malleability and ductility is also an important metallic characteristic.
- Generally the metals are hard and dense.
- The elements on the left hand side of the periodic table show metallic characteristics except hydrogen.
Follow the formula.. there’s not enough in this question for me to solve
In order to calculate the new freezing point, we must first find the depression. This is given by:
ΔT = Kf * b * i
where Kf is the cryscopic constant for the solvent, b is the molarity of the solution in moles per kilogram and i is the van't Hoff factor, which tells us how many ions will be released when a substance is dissolved.
Kf = 1.853, b = 1.5, i = 2 (Na⁺ and Cl⁻)
ΔT = 5.5 °C
The new freezing point will be 0 + 5.5
5.5 °C
Answer: 12.011g/mol
Explanation: The molar mass of any element is usually stated at the bottom of periodic table (depending of your table anyways). Remember that the periodic table speaks to you in moles so every molar mass under the element is for 1 mole. By this I mean for example, 1 mole of Carbon = 12.011g of Carbon.
