Selenium

The balanced chemical equation for the reaction between tartaric acid and copper sulfate is: C4H6O6 + 3CuSO4 -> Cu3(C4H4O6)2 + 3SO4.

Lead used to be commonly added to gasoline as an octane booster, but due to its environmental and health risks, it has been phased out and is no longer used in car gasoline.

1.9 mol Se ( 78.96 grams/1mol Se ) = 150.024 grams

Selenium has a moderate first ionization energy, with a value of 941 kJ/mol. This means that it requires some energy to remove the outermost electron from a selenium atom.

No, selenium is not the only mineral with antioxidant functions. Other minerals such as zinc, copper, manganese, and iron also exhibit antioxidant activity in the body by helping to neutralize harmful free radicals. These minerals play essential roles in protecting cells and tissues from oxidative damage.

The central atom in selenium sulfide has a bent molecular geometry due to the presence of two lone pairs on the selenium atom. This results in a distorted tetrahedral arrangement around the selenium atom.

The abundance of selenium in the atmosphere of Earth is very low, with concentrations typically ranging from 0.1 to 1 nanograms per cubic meter of air. Selenium is not a major component of Earth's atmosphere and is mainly found in soil, water, and food sources.

Selenium typically forms an ion with a charge of -2 when it gains two electrons to achieve a stable electron configuration. This forms the selenide ion (Se2-).

Selenium sulfide, an anti-infective agent, relieves itching and flaking of the scalp and removes the dry, scaly particles that are commonly referred to as dandruff or seborrhea. It is also used to treat tinea versicolor, a fungal infection of the skin.

Selenium exists in several allotropic forms. The most stable, crystalline hexagonal selenium, is metallic gray. Crystalline mono clinic selenium is a deep red color. Amorphous selenium is red in powder form and is black in vitreous form. Gray crystalline 'metallic' selenium conducts electricity better in the light than in the dark (photoconductive) and it can convert light directly into electricity (photovoltaic).

6 but i don't know why though but its six coz it came out for my practice gcse test

Fluorine and selenium can form a type of bond known as a covalent bond, where they share electrons to achieve a stable electron configuration. In this bond, both fluorine and selenium atoms contribute to the bond by sharing electrons rather than transferring them completely.

There is limited data on the prevalence of selenium deficiency in Canada. However, research suggests that certain populations, such as those with specific medical conditions or following restrictive diets, may be at higher risk. It is recommended to consult a healthcare provider for personalized advice on assessing and addressing selenium status.

Selenium deficiency can be diagnosed through blood tests that measure levels of selenium in the body. Symptoms such as muscle weakness, fatigue, and hair loss may also indicate a deficiency.Consulting with a healthcare provider is important for proper diagnosis and treatment.

You should use selenium sulfide 2.25% shampoo as directed by your healthcare provider or as indicated on the product label. In general, it is typically used 2-3 times per week at the beginning of treatment, and then less frequently for maintenance once symptoms improve. It is important to follow the specific instructions provided for your individual situation.

Use for decolourizing of Ferric and Ferrus oxide , green colour to colourless. But Selenium have many oxidation state and can change oxidation state when furnace condition change Reduction to Oxidation.

Selenium, when forming an ion, gains two electrons. The name of the anion is Selenide, and it has a -2 charge. I found this by looking at the periodic table. Find Selenium, number 34, and you can see that two spaces to its right is a noble gas. This means is gains two electrons when forming an ion. I hope I helped.

Yes, vitamin D plays a role in the immune response of cows by supporting proper immune function and reducing inflammation. Selenium is also important for immune function in cows as it helps protect against oxidative stress and improves white blood cell activity. Both nutrients are essential for maintaining a healthy immune system in cows.

Selenium is a mineral that acts as an antioxidant in the body, which may help protect cells from damage that can lead to cancer. However, more research is needed to determine the role of selenium in cancer prevention and treatment. It is important to talk to a healthcare provider before using selenium supplements for cancer.

The most common isotope of selenium is selenium-80, which makes up about 50% of naturally occurring selenium.

Selenium is stored in the heart, kidney, lung, liver, pancreas and muscle tissue. Selenium is found in nuts, meat, mushrooms, fish and eggs.

Selenium is important to the world because it is an essential micronutrient for humans and animals, playing a key role in various physiological functions such as antioxidant defense and thyroid hormone metabolism. It also has industrial applications, being used in the production of glass, electronics, and pharmaceuticals. Furthermore, selenium is crucial for environmental health as it contributes to the balance of ecosystems and helps mitigate pollution.

no. it is an element and will be homogeneous
