Chemistry

zzz [600]3 years ago
7 0

Answer:

33/16 S

Explanation:

In beta decay, the atomic number of the daughter nucleus increases by one unit while the mass of the daughter nucleus remains the same as that of the parent nucleus.

Hence, if we know that a beta decay has occurred, then the parent nucleus must have the same mass as its daughter nucleus but have an atomic number that is less than that of the daughter nucleus by only one unit, hence the answer above.

An ion has 14 neutrons, 10 electrons, and a mass number of 27 what element
nasty-shy [4]

The ion is Al³⁺

mass number - number of neutrons= atomic number

27 - 14 = 13

Aluminum has an atomic number of 13, thus we know this is the metal in question. Also, because the aluminum has only 10 electrons, (3 less than a neutral atom of aluminum would have), its charge must be 3+

A dental assistant is preparing to use a chemical that has a number 2 in a blue triangle on the chemical label. Before using the
Effectus [21]

Labels must clearly identify the chemical and include information on its hazards, plus instructions and information on its safe storage, handling, use, and disposal.

Product Identifier: The method used to identify the chemical (in the ingredient disclosure). On the label, include the complete chemical name or number that is used for the hazardous product. Both the label and SDS must have the same information. Abbreviations for chemicals are not accepted.

Signal Words: Assigned to a GHS hazard class and category, "Danger" or "Warning" are used to underline hazards and show the relative level of severity of the hazard.

Danger Statements: Typical expressions that are associated with a hazard class and category and that define the hazard's characteristics. On a label, there must be mention of every danger that applies.

Precautionary Statements: A term that describes actions that should be performed to reduce or eliminate negative effects brought on by exposure to or inappropriate storage of a substance.

Symbols (hazard pictograms): Convey information about environmental, physical, and health hazards that are categorized and allocated to a GHS hazard class.
