question 1

Multiple Choice

Given the following information about the activity series, predict whether the given reaction will occur or not. If it does occur, write a balanced equation. Cu < H₂ < Sn < Fe < Zn < Mg Fe(s) + SnCl₂(aq) →

• A)No reaction will occur.
• B)Fe(s)+ SnCl₂(aq)→ FeCl(aq)+ SnCl(aq)
• C)Fe(s)+ SnCl₂(aq)→ FeCl₂(aq)+ Sn(s)
• D)Fe(s)+ SnCl₂(aq)→ FeZn(s)+ Cl₂(g)
• E)Fe(s)+ SnCl₂(aq)→ FeCl₂(aq)+ Sn(aq)

Definitions:

Independent Samples

Two or more groups of data that are collected from separate, non-related populations or entities.

Dependent Samples

Pairs of samples where the members of one sample are related or matched to the members of the other sample, often used in before-and-after studies.

Dependent-Samples T Test

A method in statistics for comparing the average differences between two related or matched groups to determine if the differences are not due to random chance.

Regression

A statistical method used to determine the relationship and predict outcomes between dependent and independent variables.
