Answer:
Ionic.
Explanation:
Elements with higher electronegativity values are better at attracting electrons in a chemical bond.
- A chemical bond is considered "ionic" if the electronegativity difference between the two bonding atoms is greater than
. - Otherwise, this chemical bond is considered "covalent".
In this example, the difference between the electronegativity of oxygen and lithium is
. Since
, the bond between the two elements would likely be ionic.
It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.
Answer:
300K.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 300L
Initial temperature (T1) = 200K
Final volume (V2) = 450L
Final temperature (T2) =..?
Since the pressure is constant, the gas is obeying Charles' law.
Using the Charles' law equation, we can obtain the new temperature of the gas as follow:
V1/T1 = V2/T2
300/200 = 450/T2
Cross multiply to express in linear form
300 x T2 = 200 x 450
Divide both side by 300
T2 = (200 x 450)/ 300
T2 = 300K
Therefore, the new temperature of the gas is 300K.
The Law of Conservation of Mass says that there can be no more or no less mass after a chemical reaction, so 24.4g+ 12.3 g has to equal the mass of Ca(OH)2
