Chapter 2, Problem 2.13P
Interpretation Introduction

(a)

Interpretation:

How many panels are required.

Concept introduction:

Kilowatt hour is a commercial unit of energy which is widely used in electrical application.

Kilowatt hour can be calculated by multiplying 1000 W with 3600 s. The consumption by home and other small business are measured in kilowatt hour while the consumption by medium and large-scale industries are measured in Megawatt hour.

Applying conversion factor to find the value of kWh as follows:

1kWh=1000×60×60=3600000J

Interpretation Introduction

(b)

Interpretation:  What would be total cost saving

Concept introduction:

Kilowatt hour is a commercial unit of energy which is widely used in electrical application.

Kilowatt hour can be calculated by multiplying 1000 W with 3600 s. The consumption by home and other small business are measured in kilowatt hour while the consumption by medium and large-scale industries are measured in Megawatt hour.

Applying conversion factor to find the value of kWh as follows:

1kWh=1000×60×60=3600000J

Interpretation Introduction

(c)

Interpretation:  Motivation to decide to install the solar panels

Concept introduction:

Kilowatt hour is a commercial unit of energy which is widely used in electrical application.

2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.
