Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

Because we synthesized the two most common kidney stones‚ calcium oxalate and calcium phosphate‚ we will focus on those two in the discussion of formation‚ treatment‚ and prevention. Calcium stones like calcium oxalate and calcium phosphate stones form when urine is “supersaturated with the constituent ions that comprise the stone” (Figge). This means‚ when urine is supersaturated with calcium and oxalate ion that type of stone is more likely to form. This supersaturation results from the ionic activity

It aids the development of bones and bone mass. 3 Explain how the body controls calcium levels in the bones and blood. Be sure to describe the roles of parathyroid hormone (PTH) and calcitonin in detail. (2 points) The body controls calcium levels

temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE the calcium chloride is what releases the

Calcium hypochlorite is a chemical compound with formula Ca(ClO)2. It is widely used for water treatment and as a bleaching agent. This chemical is considered to be relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with

heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms of muscular contraction‚ will last roughly as long contraction. This is

2013). 2. Explain the relationship between calcium and bones. (1 point) Calcium is essential for maintaining necessary level of bone mass to support structures of the body. The body uses calcium for heart‚ blood‚ muscles and nerves. It can be lost through bodily process like sweating‚ waste‚ shedding of hair‚ skin and fingernails. The close relationship between bone and calcium is the principal processes of calcium metabolism. Bone contains about 99% of calcium in the body and can behave as an adequate

The importance of calcium and phosphorus is that they play a role in the body and their role is to build bones and teeth this is because they allow rigidity to the structure of the bones and teeth. This is because bones are continuously being rebuilt with new bone being formed and also teeth as well but at a slower rate but this is why calcium and phosphorus is needed and is important. The role of calcium is that it circulates blood and it also helps blood clot in other body tissues and also plays
