Worksheet - Acids‚ Bases and Salts 1. I am pure water. When heated my pH (increases‚ decreases)‚ because more of my water molecules dissociate. 2. I am a 0.020 M solution of weak acid‚ HA. If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am

What is the care value base? The care value base is a range of standards for health and social care. It is designed to guide the practice of professionals working in this area. The aim of the standards is to improve clients’ quality of life‚ by ensuring that each person gets the care that is most appropriate for them as an individual. The care value base offers guidance‚ and sets standards‚ in three main areas of health and social care: ➢ Fostering equality and diversity ➢ Fostering people’s

Introduction: Plants have adaptations to help them survive in harsh environments; Some live in a forests where plants have to find a way to get the sunlight they require‚ some live in an aquatic environments where there is an abundance of water‚ and some live in desert environments where it is dry and very hot. These plants have different adaptations such as leaf size‚ leaf surface‚ stem size‚ and their stress level. In this lab‚ we will be discussing plants from 3 different regions; forest‚ aquatic

percent of animal life lives in the trees. It is filled with lakes‚ river‚ swamps and a wide variety of different terrain. There is an overabundance of green plant life that strives on the heavy rains received each year. The forest floor is full of nutrients which the large tree strive on giving the canopy effects and which houses so much plant and animal life. 2.

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells
