In terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.?
The chemical reaction goes faster if calcium carbonate is powdered.
The rate of secretion of parathyroid hormone increases when?
the calcium levels in the blood decrease. This prompts the parathyroid glands to release more parathyroid hormone to prevent hypocalcemia by stimulating the release of calcium from bones, increasing calcium absorption in the intestines, and reducing calcium excretion in the kidneys.
How fast does chalk dissolve in water?
Chalk, which is primarily composed of calcium carbonate, dissolves very slowly in water due to its low solubility. The rate of dissolution can vary depending on factors such as temperature and agitation. In general, it can take several hours to several days for chalk to fully dissolve in water.
How might you increase the reaction rate between calcium carbonate and acid?
Possible actions:- stirring- heating- increase of the acid concentration- fine grinding of calcium carbonate- increasing the pressure
What is calcium use for?
Calcium is a mineral that is important for bone health, muscle function, nerve transmission, and blood clotting in the body. It plays a crucial role in maintaining strong bones and teeth, as well as supporting various cellular functions.

What Factors that influence the purity of a precipitate?
Factors that influence the purity of a precipitate include the solubility of the precipitate in the reaction mixture, the pH of the solution, the presence of impurities or competing ions, the temperature of the reaction, and the rate of precipitation. Proper isolation techniques and careful control of these factors are essential to ensure the purity of the precipitate.
In copper reaction why do you need to use very hot distilled water in washing the black precipitate?
Using hot distilled water helps to dissolve the soluble impurities that may be present in the black precipitate, leaving behind a purer copper product. The hot water also increases the rate of dissolution, making the washing process more efficient. Additionally, the use of distilled water ensures that no additional impurities are introduced during the washing process.
Which nutrient increases the absorption rate of calcium?
Vitamin D
How does increased ventilation rate affect arterial blood?
It will induce a respiratory alkalosis, as carbon dioxide is washed out of the blood by the increased ventilation rate.
What effect does changing the concentration of calcium ions have on the coagulation of milk?
the rate of coagulation increases as the concentration of calcium ions increase.
What vitamin influences the rate at which the kidneys excrete calcium?
Vitamin D
What is the use of anhydrous calcium chloride in the experiment of rusting of metals?
Anhydrous calcium chloride can be used in the rusting of metals experiment to create a desiccating environment. By absorbing any water vapor present in the air, it helps to accelerate the rusting process by increasing the rate of oxidation of the metal. This can lead to a quicker and more visible demonstration of the rusting process for educational purposes.
What effect changing the concentration of calcium ions has on the rate of coagulation of milk?
Increasing the concentration of calcium ions can accelerate the rate of coagulation of milk. This is because calcium ions bind with the negatively charged casein proteins in milk, causing them to come together and form a gel-like structure, leading to coagulation. Conversely, decreasing the concentration of calcium ions can slow down the rate of coagulation.
What effect does calcium have on the heart rate?
The resting membrane potential is maintained by the distribution of positive and negative charged ions across both sides of the cell membrane. At rest, calcium concentration in cells of the heart is low as compared to the outside. At action, calcium channels in the membranes open, thereby allowing calcium to rush into the cells. So raising the heart rate.
Effect of calcium ions on the heart rate?
Calcium has no effect on heart rate. It does, however, have an effect on how hard the heart squeezes (inotropic effect). Heart rate is effected by the slow sodium channels in the pacemaker cells in the right atrium (and other pacemaker cells if the SA node is malfunctioning).
Is whole milk high in calcium but also high in fat?
All Milk has a high calcium rate. Whole milk would have the same amount of Calcium as 2%, but yes, it would have more fat
