Answer:
The answer is D (contains index fossils)
Explanation:
Here is an image of the periodic table. Hope this helps.
By increasing atomic number, the Periodic Table organises elements in chemistry. Since groups of elements share comparable properties because they all have the same number of electrons in their outer shell, each row represents a period and each column represents a group.
Interpreting the Periodic Table involves understanding its structure and how the elements are arranged.Elements in the periodic table are ordered by increasing atomic number, which corresponds to the number of protons in an atom's nucleus. Each row represents a period and the columns represent groups. Because all members of a group have an equal number of electrons in their outermost shell, all members of that group share characteristics. For instance, the elements fluorine (F) and chlorine (Cl), which both belong to group 17, have seven electrons in their outermost shells and share other characteristics. The Periodic Table is an essential tool in the field of chemistry as it allows scientists to understand patterns and properties of elements.

Explanation:
Homogeneous mixture is separated using two stage separation process: mobile stage and stationary stage. The mobile phase are absorbent such as water, chemicals while the stationary stage is the column used for the separation process. The integral method of separation of homogeneous mixtures is called chromatography (analytical or preparative). Other method of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture.
While heterogeneous mixtures are separated based the properties of the components. One method of separation of solids suspended in liquids is simple filtration.
B. The noble gases
C. The halogens
D. The alkaline earth metals
Answer:
C. The halogens
Explanation:
Show what the following molar ratios should be.
a. C4H10 / O2 2:13 (example) b. O2 / CO2
c. O2 / H2O
d. C4H10 / CO2
e. C4H10 / H2O
also give an explanation
Answer:
a. C₄H₁₀/O₂ = 2:13 (example)
b. O₂/CO₂ = 13:8
c. O₂/H₂O = 13:10
d. C₄H₁₀/CO₂ = 2:8
e. C₄H₁₀/H₂O = 2:10
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O
The molar ratios are the same as the coefficients in front of the formulas.
