There are many acids which may react with the metal...
If they react,then the metal may lost its lustre,strength etc.
In short, the reaction of the metal with the acid is not desirable..Hence the metal cleaner must not contain the acid.
The term "complete protein" refers to amino acids, the building blocks of protein. A protein must contain all nine of these essential amino acids in roughly equal amounts.
Broken down to the molecular level ... And in the case of proteins, down to amino acids.
They contain h2o and an egg
The conditionally essential amino acids in humans are the amino acids arginine, cysteine, glycine, glutamine, histidine, proline, serine and tyrosine. They are considered conditionally essential, which means they are not normally required in the diet, but must be supplied as a supplement to specific populations that do not synthesize it in adequate amounts. An example would be with the disease phenylketonuria (PKU). Individuals living with PKU must keep their intake of phenylalanine extremely low to prevent mental retardation and other metabolic complications. However, they cannot synthesize tyrosine from phenylalanine, so tyrosine becomes essential in the diet of PKU patients.
Magnetic objects must contain atoms with unpaired electrons. No unpaired electrons=no magnetism.
if a block of metal is attracted to a magnet it must have flowing charged particles (electrons)
No, each conduit must contain a separate grounding conductor.
Nucleic acids contain sugar, phosphate groups, and nitrogenous bases, which are not present in carbohydrates or amino acids. They are the building blocks of DNA and RNA, playing a crucial role in genetic information storage and transfer.
The term "complete protein" refers to amino acids, the building blocks of protein. A protein must contain all nine of these essential amino acids in roughly equal amounts.
Our body needs twenty two amino acids and can manufacture some of it. There are some amino acids that cannot be manufactured by our body and therefore must be obtained from our diet. Proteins contain combinations of different amino acids.Some of them contain all amino acids required by the body
Oxoacids are acids specifically containing oxygen. Different oxyacids are defined by their extra elements, but all of them contain hydrogen and oxygen.
Acids are compounds that have a pH less than 7. They usually contain hydrogen ions (H+) that can dissociate in water to form hydronium ions (H3O+). Acids can also contain an anion component, such as chloride in hydrochloric acid (HCl).
An acid must contain hydrogen ions (H+) in order to be classified as an acid. These hydrogen ions are what allow acids to donate protons in chemical reactions.
1. An alkali must contain a metal ion 2. Alkali sometimes can neutralize acid, if it is applied with enough force 3. All alkalis are inedible 4. For an alkali to be found in nature, it must not contain radioactivity 5. Uses of alkalis include tanning leather, cleaning, and scrubbing
The eight amino acids that must be obtained from the diet are called essential amino acids. These amino acids are not produced by the body and must be obtained from food sources to support various bodily functions and processes.
Many acids react with most metals, often producing soluble substances. Acid + metal --> salt + water. This 'eats' away at the container and causes it to leak. Glass (almost always) and polythene are unaffected by acids. However, before the advent of polythene, concentrated sulfuric acid was stored in lead vessels.
The if statement must contain else.
