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.
To avoid corrosion of metals
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.
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.
They contain h2o and an egg
Magnetic objects must contain atoms with unpaired electrons. No unpaired electrons=no magnetism.
I assume you must want phosphorous as the answer. Neither amino acids or carbohydrates contain the element phosphorous.
if a block of metal is attracted to a magnet it must have flowing charged particles (electrons)
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
No, each conduit must contain a separate grounding conductor.
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.
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.
No. Chemical compounds contain two or more different elements. H2O is a compound that does not contain a metal.There are many other examples, all the organic compounds for instance.
Possibly nothing, depending on which definition of "acid" you use. All Bronsted-Lowry acids must contain hydrogen, but many BL bases do as well, so that's not necessarily as useful as might be hoped.
essential amino acids
The if statement must contain else.
Depends on what metal and what acid. Most common metals can be attacked by some type of acid. Other more rare and exotic metal are more resistant. Gold Platinum are resistant to almost all acids except for a mixture of Nitric and Hydrochloric acid (aqua regia) and in the case of platinum the mixture must be hot. Tungsten and Tantalum are also in this category. The only metal that is completely resistant to all acids at any temperature is Iridium, a platinum group metal. So the answer would be Iridium.
RNA is the most amino acids.
