OSHA standards appear in the ___________ and are then broken down into ____________.
Answers
The answer is
OSHA standards appear in the Code of Federal Regulations (CFR) and was then broken down into two parts.
The explanation:
OSHA standards are rules that describe the methods that employers must use to protect their employees from hazards. There are OSHA standards for Construction work, Maritime operations, and General Industry, which is the set that applies to most worksites. These standards limit the amount of hazardous chemicals workers can be exposed to, require the use of certain safe practices and equipment, and require employers to monitor hazards and keep records of workplace injuries and illnesses
It contains standards to ensure a comfortable and high quality research tools like the databases. These standards are to be strictly monitored to ensure the safety of workers.

Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter or energy is created or destroyed in a chemical reaction---only changed. There are so many chemical reactions that it is helpful to classify them into 4 general types which include the following:SYNTHESIS REACTION
In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product is another way to identify a synthesis reaction.
For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance-----water!
The chemical equation for this synthesis reaction looks like:
reactant + reactant -------> product
To visualize a synthesis reaction look at the following cartoo
In the cartoon, the skinny bird (reactant) and the worm (reactant) combine to make one product, a fat bird.
DECOMPOSITION REACTION
In a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products. Basically, synthesis and decomposition reactions are opposites.
For example, water can be broken down into hydrogen gas and oxygen gas. The chemical equation for this decomposition reaction looks like:
reactant -------> product + product
To visualize a decomposition reaction look at the following cartoon:In this cartoon the egg (the reactant), which contained the turtle at one time, now has opened and the turtle (product) and egg shell (product) are now two separate substances.SINGLE REPLACEMENT REACTION
In a single replacement reaction a single uncombined element replaces another in a compound. Two reactants yield two products. For example when zinc combines with hydrochloric acid, the zinc replaces hydrogen. The chemical equation for this single replacement reaction looks like:
reactant + reactant ---------> product + product
To visualize a single replacement reaction look at the following cartoon:
Notice, the guy in the orange shirt steals the date of the other guy. So, a part of one of the reactants trades places and is in a different place among the products.DOUBLE REPLACEMENT REACTION
In a double replacement reaction parts of two compounds switch places to form two new compounds. Two reactants yield two products. For example when silver nitrate combines with sodium chloride, two new compounds--silver chloride and sodium nitrate are formed because the sodium and silver switched places. The chemical equation for this double replacement reaction looks like:
reactant + reactant ---------> product + product
To visualize a double replacement reaction look at the following cartoon:

Answer:
Molecular bonding cannot occur without electrons.
Explanation:
In order to be 100% correct, the answers should be electrons, protons and neutrons. Since moleculas are formed by atoms and atoms are formed by electrons protons and neutrons.
However, if we consider only the bonding itself, the most important atomic particle is the electron. Molecular or convalent bonding happens when atoms share electrons pairs to reach stability.

Answer:4.5 moles of sulfate ions are present in 1.5 moles of .
Explanation:
1 mol of gives 3 moles of sulfate ions.
Moles of sulfate ion in 1.5 moles :
4.5 moles of sulfate ions are present in 1.5 moles of .
Moles are the fraction of the chemical unit of the atoms, molecules, etc. The moles of sulfate ion present in 1.5 moles of aluminum sulfate is 4.5 moles.
What are moles?
Moles are the ratio of the mass of the substance to that of the molar mass of the substance. Moles are given in mol.
The reaction can be shown as:
From the reaction, it can be concluded that 1 mole of aluminum sulfate will give 3 moles of sulfate ions.
The moles of sulfate ions in 1.5 moles of aluminum sulfate will be,
Therefore, 4.5 moles of sulfate ions are present in aluminum sulfate.
