What is calcium for a rabbit?

User Avatar

Asked by Wiki User

Calcium is an essential mineral required for a rabbit's overall health, including proper growth and development of bones and teeth. However, too much calcium can lead to health issues like urinary tract problems. It is important to provide a balanced diet to ensure the right amount of calcium for a rabbit's specific needs.

Why does the body have systems to remove calcium from bones if calcium is to low?

User Avatar

Asked by Wiki User

When calcium levels are low, the body may release calcium from the bones into the bloodstream to maintain a normal balance in the blood. Bone is a reservoir for storing calcium, which can be mobilized when needed by the body for various functions such as muscle contraction and nerve signaling. If calcium levels are consistently low, it can lead to weakening of the bones and other health issues.

How many electrons are in a calcium atom and in a calcium ion?

User Avatar

Asked by Wiki User

A calcium atom has 20 electrons, as it has 20 protons to maintain a neutral charge. A calcium ion, specifically Ca2+, has lost two electrons, so it has 18 electrons.

What is the electronic configuration of calcium in calcium hydroxide?

User Avatar

Asked by Wiki User

The electronic configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2. In calcium hydroxide (Ca(OH)2), calcium loses its two outer electrons to form Ca2+ ion, which has the electronic configuration 1s2 2s2 2p6 3s2 3p6.

How do you make calcium sulphate using calcium carbonate?

User Avatar

Asked by Wiki User

To make calcium sulfate using calcium carbonate, you can react calcium carbonate with sulfuric acid. The chemical equation for this reaction is: CaCO3 + H2SO4 → CaSO4 + H2O + CO2. By mixing these two compounds, calcium sulfate can be produced along with water and carbon dioxide as byproducts.

What is the difference between calcium and calcium chloride?

User Avatar

Asked by Wiki User

Calcium is a chemical element with the symbol Ca and atomic number 20. Calcium chloride is a compound made up of calcium and chlorine ions (CaCl2). While calcium is an essential mineral for the human body, calcium chloride is often used as a de-icing agent, in food preservation, and in various industrial processes.

Why do doctors recommend people over 45 years of age to drink milk and eat more foods that contain calcium?

User Avatar

Asked by Wiki User

Doctors recommend people over 45 to consume more calcium-rich foods like milk to help prevent osteoporosis, a condition where bones become weak and brittle. Adequate calcium intake can help maintain bone density and reduce the risk of fractures and other bone-related issues as people age.

How many calcium ions in 0.625 mol of calcium nitride?

User Avatar

Asked by Wiki User

There are 1 calcium ion in each formula unit of calcium nitride, which is Ca3N2. Therefore, in 0.625 mol of calcium nitride, there are 0.625 mol of calcium ions.

Is calcium hydroxide and calcium carbonate the same?

User Avatar

Asked by Wiki User

No, calcium hydroxide (Ca(OH)2) and calcium carbonate (CaCO3) are not the same. Calcium hydroxide is a compound that is used in construction and agriculture, while calcium carbonate is a common mineral found in rocks and used in various industries like pharmaceuticals and food.

How many atoms of calcium are present in 60.8 g of calcium?

User Avatar

Asked by Wiki User

First you need to find how many moles of calcium that is. Since 1 mole of calcium is 40.078g you need to divide 60.8g by how much is one mole (60.8 / 40.078 = 1.517 moles). Once you know how many moles you have (1.517) you can find how many particles there are. There are 6.02 *10^23 atoms in one mole (Avagadro's number), so your final answer will be, 6.02*10^23 x 1.517 = 9.132 * 10^23

Is calcium chloride the same as calcium hypochlorite?

User Avatar

Asked by Wiki User

No, calcium chloride and calcium hypochlorite are not the same. Calcium chloride is a chemical compound used for de-icing roads and in food preservation, while calcium hypochlorite is a chemical compound used as a disinfectant and bleaching agent, such as in swimming pools.

Where is excess calcium stored when blood calcium levels increase?

User Avatar

Asked by Wiki User

Excess calcium is stored in the bones when blood calcium levels increase. This process is regulated by hormones such as calcitonin and parathyroid hormone, which help maintain calcium balance in the body.

If you are allergic to calcium what do you do?

User Avatar

Asked by Wiki User

If you are allergic to calcium, it is extremely rare and typically not a standalone allergen. Speak with a healthcare provider for guidance on managing potential reactions and to determine if other underlying issues may be causing symptoms. Avoiding the consumption of foods high in calcium may be recommended, but consultation with a medical professional is essential.

Why is calcium in steel?

User Avatar

Asked by Wiki User

Calcium is added to steel during the steelmaking process as a deoxidizer and desulfurizing agent. It helps remove impurities like oxygen and sulfur from the steel, which can improve its properties such as strength and machinability.
