Answer:

Hess's law:

First reaction:

Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ

Second reaction:

2Ca (s) + O₂ (g) → 2CaO (s) ΔH₂ = -1269 kJ

Overall reaction:

CaO (s) + CO₂ (g) → CaCO₃ (s) ΔH = ?

According to the Hess law of constant heat summation, the enthalpy of the overall reaction is the sum of the enthalpy of both reactions but this will not give the enthalpy of the overall reaction in this case. The enthalpy of the overall reaction is rather obtained by halving the enthalpy of the second intermediate reaction and reversing its sign before taking the sum as shown below;

Enthalpy of Intermediate reaction 1 + ½(- Enthalpy of Intermediate reaction 2) = Enthalpy of Overall reaction

The information shown in this population pyramid is a graphical representation of the country's current population of males and females, birth and death rates, population size, life expectancy, age and sex ratio etc.

What is population pyramid?

A "population pyramid" is a graphical representation of a population's age and gender makeup. It depicts the current population of a country, separated into males and females.

The population pyramid pattern is used to investigate the population using graphs because the shape of the population is determined by two variables: age and sex composition.

As a result, the population pyramid depicts births, deaths, ages, and sex ratios, among other things.

type ''How did geographical features of the country impact Japan's growth and expansion'' and click the 2nd site which is a file with all the info you need! i wish I can send it to you but I don't know how

Geographical features have played a significant role in shaping the growth and expansion of China. China is characterized by vast mountain ranges, such as the Himalayas and the Kunlun Mountains. These mountains have acted as natural barriers, providing protection against invasions and external threats. They have helped in creating a sense of isolation, allowing China to develop its own distinct culture and civilization.

China is home to several major rivers, including the Yangtze and Yellow Rivers. These rivers have served as transportation routes, facilitating trade and communication between different regions of the country. They have also supported agriculture, as the fertile plains surrounding these rivers have been vital for food production.

China has a long coastline along the Pacific Ocean. This has enabled maritime trade and contact with other countries, leading to the development of coastal cities and the expansion of trade networks. The coastal areas have been centers of economic activity and have played a crucial role in China's growth and development.

China has vast desert regions, such as the Gobi Desert and the Taklamakan Desert. These arid landscapes pose challenges for agricultural development and human habitation. However, the Chinese have found ways to adapt, utilizing advanced irrigation techniques and building the Great Wall as a defense against desert nomads.

Overall, the geographical features of China have influenced its growth and expansion by shaping its cultural identity, providing natural defenses, facilitating trade and communication, and posing challenges that required innovative solutions. Understanding and harnessing the opportunities and challenges presented by the country's diverse geography has been crucial in China's historical development.

China has overcome its geographical challenges through various strategies and innovations:

1. Construction of the Great Wall: To protect against invasions from nomadic groups in the north, the Chinese constructed the Great Wall. This immense fortification not only served as a defensive barrier but also enabled efficient troop movements and communication along the northern border.

2. Development of advanced irrigation systems: China's agricultural productivity was enhanced by the construction of intricate irrigation systems. Canals, terraced fields were built to overcome the challenges of varying terrain and ensure sufficient water supply for crops.

3. Creation of the Grand Canal: The Grand Canal, stretching over 1,100 miles, connected major rivers and facilitated internal trade and transportation. This extensive waterway system allowed goods to be transported more efficiently and played a crucial role in China's economic development.

4. Maritime exploration and trade: Despite its long coastline, China faced challenges in navigating its waters due to treacherous currents and monsoons. However, Chinese sailors developed advanced navigational techniques such as compasses and improved shipbuilding methods, enabling extensive maritime exploration and trade along the Silk Road and beyond.

5. Urban planning and infrastructure development: China's densely populated regions necessitated efficient urban planning. The construction of cities with carefully designed layouts, such as Beijing's Forbidden City, demonstrated China's ability to adapt to its geographical challenges and provide effective governance.

6. Technological advancements: Over time, China has achieved significant technological advancements in various fields, such as agriculture, transportation, and communication. Innovations like the development of high-yield rice varieties and the construction of high-speed rail networks have helped overcome geographic limitations and fostered economic growth.
