Answer:
1. Many different hypotheses will be tested.
Explanation:
Scientists test every hypothesis they make for their investigation, before moving onto bigger conclusions.
Answer:
D.
Explanation:
CH₃C≡ CCH₂CH₂Cl
Since there are 5 carbons so the suffix used is "pent"
There is a triple bond so its alkyne
So the compound becomes 2-pentyne (2 because the triple bond is with the 2nd carbon)
Then,
The functional group of chlorine is attached with 5th carbon So the compound becomes
5-chloro,2-pentyne
This is commonly true, but not always.
Carbon dioxide is CO2...if it’s broken down it will be C and O which are carbon and oxygen
Answer:
Mg₃(PO₄)₂
Explanation:
This is a neutralization reaction between an acid and a base
The acid here is H₃PO₄
base is Mg(OH)₂
Every chemical reaction is made up of reactants on the left side and products formed on the right hand side of the expression;
3Mg(OH)₂
+ 2H₃PO₄
→ Mg₃(PO₄)₂ + 6H₂O
The reaction above is a double replacement reaction in which two ionic compounds gives an insoluble precipitate as a product when their ions displace one another in solution.
The solid formed is Mg₃(PO₄)₂
