Is milk an acid or base?
Cow’s milk Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.
What is the 92 element?
UraniumUranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.
What are some examples of element?
An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.
What is a basic compound?
Bases are generally compounds that can neutralize an amount of acids. Both sodium carbonate and ammonia are bases, although neither of these substances contains OH − groups. Both compounds accept H+ when dissolved in protic solvents such as water: Na2CO3 + H2O → 2 Na+ + HCO3− + OH.
What are the 4 types of compounds?
There are four types of compounds, depending on how the constituent atoms are held together:molecules held together by covalent bonds.ionic compounds held together by ionic bonds.intermetallic compounds held together by metallic bonds.certain complexes held together by coordinate covalent bonds.

Is bleach an acid or base?
For domestic use, bleach usually contains 5% sodium hypochlorite, giving it a pH of around 11 and making it mildly irritating to the skin. Concentrated bleach (10-15% sodium hypochlorite) is highly alkaline (pH ~13) and now is now so corrosive that it can burn skin on contact.
Is a mixture?
In chemistry, a mixture is a material made up of two or more different substances which are physically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.
