What is the definition of base area?Space and Astronomy
It refers to the area of one of the bases of a solid figure. It can be used to determine the volume of solid figures.
What is a definition for a base?
base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).
What is the formula for base area?
Formulas for finding the Area of Base of Geometric Shapes
|Triangle||1⁄2 b*h b=base h=height b=base h =height|
|Trapezoid||1⁄2 h ( b_1+ b_2 ) h = height b_1=base 1 b_2=base 2|
|Square||s^2 s =side|
|Parallelogram||base * altitude|
|Pentagon||1⁄2 a*p a = apothem P = perimeter|
Is base the same as area?
Because the area of a rectangle is base times height (which is the same thing as length times width), and a triangle is half of a rectangle.
What is base example?
Examples of bases are sodium hydroxide, calcium carbonate and potassium oxide. A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. …
What are bases Class 10?
Bases are those substances which have bitter taste. They turn red litmus to blue. Those bases which are soluble in water are called alkali. For Example: NaOH,KOH, Mg(OH) 2 , NH 4OH. A base is a substance which dissolves in water to produce hydroxide ion in solution.
What is the definition of base in biology?
Definition. noun, plural: bases. (1) (molecular biology) The nucleobase of a nucleotide involved in base pairing, as of a DNA or RNA polymer. (2) (anatomy) The lowest or bottom part of a plant or animal organ closest to the point of attachment.
What is a base class 7?
The substances that taste bitter are called base and their nature is basic. They are slippery to touch. Example: baking soda containing sodium hydrogen carbonate, Milk of magnesia, Soaps, Lime water containing calcium hydroxide, Household cleaners.
What are the 3 types of bases?
The word base has three different definitions in chemistry, and they are Arrhenius base, Bronsted base, and Lewis base. All the base definitions agree to the fact that bases react with acids.
What are the bases?
In the United States, mostly among American teenagers, baseball metaphors for your physical intimacy with someone and sex are often used as euphemisms. Bases is a term that, in its origins, has to do with, out of all things, the sport of baseball.
What are called bases?
A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. Bases include the oxides, hydroxides and carbonates of metals. The soluble bases are called alkalis. Sodium hydroxide is an alkali.
Where are bases found?
Bases are less common as foods, but they are nonetheless present in many household products. Many cleaners contain ammonia, a base. Sodium hydroxide is found in drain cleaner. Antacids, which combat excess stomach acid, are comprised of bases such as magnesium hydroxide or sodium hydrogen carbonate.
What is a base in your home?
Acids & Bases Found in Homes
In more familiar terms, a base is the alkaline opposite of an acid; when the two mix, they neutralize one another. The logarithmic pH scale measures a substance’s acidity or alkalinity, and chemists classify anything with a pH greater than 7.0 as a base.
Is shampoo a base?
Shampoo is a basic hair care product representing the largest segment of hair care cosmetics. Shampoo is typically in the form of a viscous liquid with some exception of waterless solid form such as a bar.
Is soap a base?
Soap is Basic.
Soaps are bases as they are salts of strong bases and weak acids. Some chemicals are also used in making soap. If the soap is too basic, it can damage the skin, the surfaces it must clean, and the clothing it must clean.
What are 5 examples of bases?
Some common strong Arrhenius bases include:
- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Barium hydroxide (Ba(OH)2)
- Caesium hydroxide (CsOH)
- Strontium hydroxide (Sr(OH)2)
- Calcium hydroxide (Ca(OH)2)
- Lithium hydroxide (LiOH)
- Rubidium hydroxide (RbOH)
Is shampoo base or acid?
Shampoo is considered acidic. Note: There were different types of shampoos available. But the main ingredient in shampoo is citric acid.
Is coffee a base?
On the pH scale, the acid content in coffee ranges from about 4.85 to 5.10, making it an acid, not a base. And as delicious as it may be, because coffee is acidic, it can be difficult for people with certain health conditions to enjoy. For most people, drinking a cup of coffee with a pH level of 5.0 is perfectly fine.
Is water a base?
Pure water is neither acidic or basic; it is neutral.
Is blood a base?
Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40. A doctor evaluates a person’s acid-base balance by measuring the pH and levels of carbon dioxide (an acid) and bicarbonate (a base) in the blood.
Is toothpaste a base?
Toothpaste is a base. It is alkaline in nature. After we have our food, the food gets breakdown and releases the acid. In order to neutralize the acidic effect in our mouths, we use toothpaste to brush our teeth.
Is milk a base?
Actually, milk has a pH of around 6.5 to 6.7, which makes it slightly acidic. Some sources cite milk as being neutral since it is so close to the neutral pH of 7.0. However, milk contains lactic acid, which is a hydrogen donor or proton donor.
Is baking soda solution a base?
A 1% molar solution of baking soda in water has a pH of 8.3 at room temperature. This number indicates that baking soda is alkaline, which gives reason for its bitter taste.So,baking soda is basic in nature.
Why is soap a base?
For example, when stearic acid reacts with lye, it loses a Hydrogen (from the OH on the end of the molecule) and attracts a sodium ion (Na+). So SOAP is a mixture of salts of fatty acids and glycerine, and it has a high (basic) pH because lye is a strong base that releases OH– molecules.
Is baking soda a base or acid?
Its superpowers come from a two-letter term: pH. That stands for “power of hydrogen” to make something either an acid or a base (alkaline). Baking soda is an alkaline substance. When it mixes with an acid, it alters the pH level.
Is bleach a base?
Chlorine bleach is a base and is especially good at removing stains and dyes from clothes as well as disinfecting.
