RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Unit 01 – Child and young person development (2:1) Give Examples of how the different aspects of development can affect each other. There is a strong connection between Physical‚ Intellectual and Social development. All developmental areas have their own unique traits and specific characteristics. However‚ they are all dependent upon and can impact each other. This can have detrimental effect on an individual’s development. Growth and development of the brain (physical development) leads to changes

Interpretation of Data When looking at my results i can safely say that the change in HCl concentration does affect the rate of reaction with the Calcium carbonate pebbles. The relationship between the change in HCl and reaction rate can be seen in the graph and raw data table presented above. If you compare the lowest concentration with the highest concentration you’d be able to see that there is a very large contrast between their averages. The average gas production of 0.1M HCl was 0.00693 kPa/s

How Variations Of 5‚ 10‚ 15‚ 20‚ And 25 Squats Affects the Respiration Rate In 14 Year- Old Year 9 Boys. The human respiratory system is made up of the lungs and the passages that lead to them. Air is breathed into the lungs‚ and oxygen from the air passes into the blood‚ which carries it around the body. The waste product‚ carbon dioxide‚ is then passed from the blood into the lungs and is breathed out. This all happens with the immense help of oxygen‚ to maintain a functional human body. However

__________________ THE SCIENTIFIC METHOD: IDENTIFYING WHICH LIQUID EVAPORATES FASTER I. Objectives To know the step-by-step procedure in conducting an experiment To determine how the process of scientific method helps us to solve a certain problem To identify which liquid evaporates faster. II. Science Concept Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. The rate of evaporation is dependent upon temperature‚ humidity‚ and wind

What Makes Rocks and Gems Different? By: Morgan Bellile Have you ever found a beautiful gem? Have you ever wondered what is in rocks? Did you know that red diamond is one of the most rare types of gems? Rocks and gems both have something in common‚ but have you ever wondered what makes rocks and gems different? Gems Gems are also known as precious stone‚ jewels‚ or just stone. What is a gemstone? A gemstone is a piece of mineral crystal‚ when the gem is cut and polished‚ it is normally used for

1/ List and describe the four factors that affect the rate of drug distribution. The four factors that affect the rate of drug distribution are absorption‚ metabolism‚ distribution‚ and excretion. a. Absorption is the movement of a drug from its site of administration into the blood. Most drugs are absorbed by passive absorption but some drugs need carrier-mediated transport. Example: Acidic drugs such as aspirin will be better absorbed in the stomach whereas basic drug
