Answer:
Li2CO3 - Lithium carbonate
Explanation:
If you look at the periodic table of elements, you will see that, from all alkali metals, Lithium is the one with the lowest atomic mass. So we can conclude that the element q in the compound qr is Lithium.
The task says that in the compound qr, r contains the elements oxygen and carbon in a 3:1 ratio. It means that we have 3 oxygen and 1 carbon atom in this compound, which can be written as CO3.
From the information above, we can conclude the compound that we are looking for is Li2CO3 - Lithium carbonate.
Form determines function is the explanation in this statement.The example is Na+ is table salt but Na is highly unstable. Understanding its form and function is very important in making an experiment. So we need to know and understand the relationship between form and function for appreciating.
Answer:
Number of moles = 0.51 mol
Explanation:
Given data:
Mass of CO₂ = 22.4 g
Number of moles = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
by putting values,
Number of moles = 22.4 g/ 44 g/mol
Number of moles = 0.51 mol
This statement is <u>TRUE.</u>
Explanation:
Due to the high heat capacity of water, it takes much more energy to have a gram of water raised by one degree compared to one gram of land. This is why during a hot day, the ground gets hotter faster than the adjacent oceans or adjacent lakes. It also takes water to lose the same amount of energy to have its temperatures drop by one degree as compared to land. During the night, therefore, this is why adjacent water bodies remain relatively warmer than land.
