Calcium
Calcium is a chemical element with the atomic number 20 and symbol Ca. It is an alkaline earth metal and one of the most abundant metals in the Earth’s crust. Calcium is also essential for living organisms, both as a catalyst for cellular processes and as a component of shells, bones, and teeth.

Calcium carbonate is heated to from calcium oxide and carbon dioxide well balanced equation?
Calcium carbonate is heated to from calcium oxide and carbon dioxide as illustrated by the chemical equation CaCO3(s) ===> CaO(s) + CO2(g).
small atomic radius.
What happens to calcium carbonate as ocean acidification increases?
As ocean acidification increases, the concentration of carbonic acid rises, leading to a decrease in the pH of seawater. This change in acidity reduces the availability of carbonate ions, which are essential for the formation of calcium carbonate (CaCO₃). Consequently, marine organisms such as corals and shellfish struggle to build and maintain their calcium carbonate structures, resulting in weakened shells and skeletons. Over time, this can disrupt marine ecosystems and affect biodiversity.
How does calcium atomic radius compare to magnesiums radius and potassium's radius?
Calcium has a larger atomic radius than magnesium because it is located further down in the periodic table, resulting in an increased number of electron shells. However, potassium, being in the same group as calcium but further down, has a larger atomic radius than both calcium and magnesium. Thus, the order of atomic radii from smallest to largest is magnesium, calcium, and then potassium.
Why do pregnant women need more calcium than not pregnant women?
Because part of everything they eat goes to the growing baby. So they need to eat a little extra all over, and particularly of some extra important stuff. Like calcium, for growing bones.
What are the elements that formed the calcium?
Calcium is an element, which means that it is made up protons/electrons and neutrons. Each calcium atom contains a total of 20 protons/electrons, and 20 neutrons.
What mass of carbon dioxide is produced when 200 tons of calcium oxide is made?
the answer is 356.96 tonnes
Why tourniquet shouldn't be tied during calcium test?
because it causes stasis and hem concentration and leads in erroneously high values
A calcium atom is larger than a calcium ion because?
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
How do you get calcium deposits out of hot tub?
try CLR. it can be bought at any grocery or home improvement store
empty the tub and follow the directions on the bottle.
Aging is an unavoidable life process, but the impact of aging can be minimized by diet, exercise and supplements. Much of the aging process is caused by decreased glandular activity and declining levels of testosterone, DHEA, HGH and other "youth" hormones. Supplements and hormone treatments, combined with other lifestyles can reduce the impact of aging.
It is the most commonly seen process in living bodies, however, scientifically, it is not normal or inevitable. The body is a complex of systems based on regeneration and healing and in theory it should be able to stand the passage of time.
Many branches of medical biology are trying to find the true reasons for aging. Beyond tear and wear (due to usage), that can be overcome through the regenerative capacities of the body, some elements present in the body, programmed for acting as neutralizers or limiting cell regeneration after some age, have been identified. It seems that the body is made for standing the passage of time but programmed for not using so well that capacity after certain age.
As your body ages, you can expect it to undergo gradual changes, at its own pace. How your body ages depends in part on your family (genetic) patterns of aging. However, your lifestyle choices have a more powerful impact on how well your body ages. Fortunately, you can control your lifestyle choices.
Aging is a normal process of life. From the time we are born, aging begins and eventually culminates in death. So far, none of us have lived to see another human being live forever. Although lifespans have extended, we are able to live longer, but not escape aging. Obviously, the better your diet andn body maintenance, the better chances you have of living longer. With that said, there are many options available today because of advanced science which can help delay the process of aging. The right diet, right supplements, and even anti-aging products like DaySkin, a physician-formulated cream which is based on the latest scientific technology to delay fine lines, wrinkles and to protect the skin from the damaging effects of the sun during the day.
Answer: Here is what the Holy Scriptures from an Awake article; In line with the physical laws of inheritance, all of Adam and Eve's descendants acquired imperfection and the inclination to sin, or do what is wrong. Says Romans 5:12: "Through one man sin entered into the world and death through sin, and thus death spread to all men because they had all sinned."
Why does a house cat live 20 years, but a similar-size opossum lives only 3 years?*Why can a bat live 20 or 30 years, but a mouse only 3? Why can a giant tortoise live 150 years, but an elephant only 70? Factors such as diet, body weight, brain size, or rate of living do not explain such diversity of life spans. The Encyclopædia Britannica states: "Locked within the code of the genetic material are instructions that specify the age beyond which a species cannot live." Maximum life span is written in the genes. But as the end of that life span approaches, what causes all the body functions to start closing down?
Molecular biologist Dr. John Medina writes: "There seem to be mysterious signals that simply show up at certain times and tell cells to quit doing their normal adult functions." He also notes: "Genes exist which can tell cells, and indeed entire organisms, to grow old and die."
Our body might be compared to a company that has been doing business successfully for decades. Suddenly the managers stop hiring and training new staff, stop repairing and replacing machines, and stop maintaining and rebuilding the premises. Soon the business will start to deteriorate. But why did all those managers change their successful policies? That question is similar to the one facing biologists who study aging. The book The Clock of Ages says: "In aging research, one of the great mysteries is trying to understand why cells stop replicating and start dying."
Is Insullin a neurotransmitter?
No, it's a "sugar transmitter" , it transports sugar to be used by the different organs of the body. So less insulin produced, more sugar concentration in the blood.
How much food rich in folic acid would you have to eat to reach your RDA?
In terms of health RDA stands for Reccommended Daily Allowence.
How do you remove calcium deposits?
Calcium can be broken down with an acidic solution of some kind. There are cleaning agents sold which are made specifically for this.
You can remove calcium deposits using baking soda and white vinegar, depending on what kind of surface you are cleaning, you can scrub the area with either steel wool or a nylon scrubber. This is a lot less expensive than store bought products. You can also use salt and vinegar.
