Answer:
Measure 20mL of the stock
Explanation:
All we need to do is to find the volume of the stock solution needed. This is illustrated below:
C1 = 2M
V1 =?
C2 = 0.400 M
V2 = 100mL
C1V1 = C2V2
2 x V1 = 0.4 x 100
Divide both side by 2
V1 = ( 0.4 x 100) /2
V1 = 20mL
Therefore, to prepare the solution, we will measure 20mL of the stock solution and make it up to the 100mL mark.
Answer & Explanation:
D orbitals begin filling with electrons after the orbital found in the 4s sublevel is filled. This occurs because the d sublevel is first found in the.
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
a₀=2
a₁=9
a₂=6
a₃=8
Answer:
E Reactivity
Explanation:
Reactivity is not one of the properties shared by metals with one another.
The reactivity of a substance is its ability to combine with other substances. Reactivity is not used to measure the physical property of a metal.
- Physical properties are those that we can sense with our senses.
- For metals, conductivity, luster, malleability are all properties of metals.
- They can be examined using our active senses.
The physical properties observed in metals derives from the metallic bonds within their atomic structure.
Conductivity, luster, malleability, ductility, magnetism etc. are some of the other physical properties of metals.
