Answer:
d
Explanation:
the you answer you need is lithium
You need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. First, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. If they meet these criteria, they will have similar properties.
The first pair: Ne (Neon) and Kr (Krypton), are noble gases found in group 8
The second pair: Li (Lithium) and K (Potassium), found in group 1
The third pair: S (Sulfur) and Te (Tellurium), found in group 6
Answer:
6
Explanation:
Any atom with the atomic number 6 is carbon and has 6 protons
Answer:
The temperature of the methanol will increase more rapidly.
Explanation:
The premise of your question is incorrect. Methanol has an OH group, so there ARE hydrogen bonds among methanol molecules.
However, the specific heat capacity of methanol is 2.53 J°C⁻¹g⁻¹, while that of water is 4.18 J°C⁻¹g⁻¹.
Thus, it takes 65 % more heat energy to raise the temperature of a given mass of water by 1 °C than it does to raise the temperature of an equal mass of methanol by the same amount.
The two samples are receiving heat energy at the same rate, so the methanol will heat up faster than the water.
