What does your number mean?

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults.

BMI values are age-independent and the same for both sexes.
The health risks associated with increasing BMI are continuous and the interpretation of BMI gradings in relation to risk may differ for different populations.

As of today if your BMI is at least 35 to 39.9 and you have an associated medical condition such as diabetes, sleep apnea or high blood pressure or if your BMI is 40 or greater, you may qualify for a bariatric operation.

If you have any questions, contact Dr. Claros.

< 18.5 Underweight
18.5 – 24.9 Normal Weight
25 – 29.9 Overweight
30 – 34.9 Class I Obesity
35 – 39.9 Class II Obesity
≥ 40 Class III Obesity (Morbid)

reaction of metals with water examples

Sodium and potassium metal are stored under kerosene oil to prevent their reaction with the oxygen,moisture and carbon dioxide of air.They are so reactive that they react vigorously with oxygen.They catch fire and start burning when kept open in the air. Sodium reacts vigorously with water to produce aqueous sodium hydroxide and hydrogen (see figure below). The products of such a reaction are the metal hydroxide and hydrogen gas. The reactions in which single reactant is oxidized and reduced is known as Disproportionation reactions. Metals below hydrogen on the reactivity series will not react with dilute acids. The heavier a metal gets, the slower and more difficult thereaction. However, some metals react slower with water. Reaction of Sulfur with Oxygen Sulfur burns with a blue flame Sulfur + oxygen → sulfur dioxide sulfur dioxide + water → sulfuric acid Generally non-metals do not react with water. Non-metals react with oxygen to form acidic oxides which form acids when dissolve in water. Normally, “light” metals react vigorously with water. Water can have more energy if it heats up. All group 1 metals undergo this type of reaction. Examples of metals that do not react with acids include copper, platinum and mercury. Metal oxides are basic in nature.They turn red litmus to blue. One notable reaction within this group is aluminum's (Al) reaction with water. Aluminum does not appear to react with water because an outer layer of aluminum oxide (Al 2 O 3) solid forms and protects the rest of the metal. Name two metals which do not react with any form of water. 3. Most oxides of non-metals are soluble. The reactivity of the metal determines which reactions the metal participates in. The reactivity series of metals can be used to predict which metals will react with acids. Group 13 elements are not very reactive with water. Give one example with a proper balanced chemical equation. 2. Disproportionation Reactions. Reaction with water - definition Some metals react with water to form metal hydroxide and hydrogen gas. Metals can react with water, acid and oxygen. 2 N a (s o d i u m) + 2 H 2 O 2 N a O H + H 2 (h y d r o g e n g a s l i b e r a t e d) ↑ Less active metals react with boiling water. Ans. Metals may also react directly with water, as when sodium combines with water to form sodium hydroxide and hydrogen gas. Some metals react very quickly and easy with water. Learn Group 1 in the Periodic Table - lithium, sodium, potassium, rubidium, ceasium (cesium), and francium, What are alkali metals, Physical and chemical properties of alkali metals, Reaction with water (videos), Reaction with chlorine, Reaction with oxygen, Chemistry: An overview of the Periodic Table, examples with step by step explanations In this type of reaction, we can find a hydrogen displacement and sometimes rarely occurring reactions involving oxygen displacement. Reaction of metal with water The order of increasing reactivity of these metals is … Non-Metal Displacement. Explain the reactions of different metals with hot water, cold water and steam. Examples of metals that do react with acids include lithium, aluminium, zinc and iron. In fact, boron (B) does not react at with water. Q. When the metals in two compounds switch places, this is called a double-replacement reaction, and when an acid and a base -- the latter formed from a metal -- become water and a salt, this is a neutralization reaction. Non-metals do not react with water. Reaction with acids : Metals react with acids to produce respective salts along with evolution of hydrogen gas. Some metals are so reactive that they are capable of replacing the hydrogen in water. Examples of water-reactive chemicals include alkali metals, alkaline earth metals, anhydrides, certain carbides, hydrides, sodium hydrosulfite, and similar chemicals. Reaction of non-metals with oxygen If a non-metal takes part in a chemical reaction with oxygen it forms an oxide. Reaction with water: Metals react with water to form their oxides or hydroxides.
