Explanation:
A chemical property is defined as the property that brings changes in chemical composition of a substance.
For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.
On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.
For example, shape, size, mass, density etc are all physical properties.
Thus, we can conclude that these may all be classified as chemical properties of a substance.
Answer:
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 25.0 L
V₂ = ?
P₁ = 2575 mm Hg
Also, P (atm) = P (mm Hg) / 760
P₁ = 2575 / 760 atm = 3.39 atm
P₂ = 1.35 atm
T₁ = 353 K
T₂ = 253 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 45.0 L</u>
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
The symbol for the hydroxide ion is OH-
Answer:
The answer to your question is below
Explanation:
1. Found in period 2. All the elements in the list are found in period 2.
a. F This option is correct
b. Be Beryllium is located in period two.
c. O also oxygen is found in period 2.
d. C Carbon is found in period 2.
2.- Can gain lose 4 electrons to become its nearest stable noble gas. Only Carbon.
a. F This option is wrong, F becomes stable when it gains 1 electron.
b. Be Beryllium becomes stable when it loses 2 electrons.
c. O Become stable when it gains 2 electrons.
<u>d. C </u><u>Become stable when it gains or loses 4 electrons.</u>
