Answer:
Two
Explanation:
The law of conservation of mass states that in an isolated system the mass present is neither destroyed nor created by chemical changes or physical changes.
This tells us that the mass of reactants must be equal to the product mass.
If 1 atom of Zn react with one atoms of sulfur, the product will be 1 molecule of zinc sulfide according to the equation below
Zn(s) + S(s) ⇒ ZnS(s)
therefore two atoms each f zinc and sulfur will product two molecules of Zn sulfide
The alkanes are saturated hydrocarbons which include propane, methane, ethane and other higher of saturated hydrocarbons.
The answer to the given problem is the letter "A" Single covalent bonds only.
The Alkanes are hydrocarbons that contain "Single Covalent Bonds Only".
Answer:
12 hydrogen atoms are present.
Explanation:
The hydrocarbon is an alkane as it contains single covalent bonds.
The first carbon attaches to 3 hydrogen atoms, the second to fourth carbon attaches to 2 hydrogen atoms each and the last (fifth) carbon have 3 hydrogen atoms.
The Alkane compound is called PENTANE with molecular formula C5H12.
Answer:no
Explanation:as long as it’s not too much of it then no , it’s not bad . food coloring gets tested to be safe for human consumption so you’re good
Answer:
A one-point pH change indicates the strength of the acid or base has increased or decreased tenfold; a 2-point change indicates a 100-fold change in acidity or alkalinity, and a 3-point change in pH indicates a 1000-fold change. Examples: • An increase in pH from 7.0 to 8.0 means the water is 10 times more basic.
