The reaction we will be doing in lab is to take sand(SiO2),baking sod(NaHCO3) and reacting that with HCl. The HCl with the react

with the NaHCO3 and one of the products is CO2. SiO2 does not react.What is the balanced chemical reaction for this chemical equation?

I believe that this equation is
SiO_{2} +NaHCO_{3} => CO_{2} + NaOH + SiO_{2}

Calculate the number of atoms of sodium in a 4.5-gram sample
allochka39001 [22]

Answer:

1.18×10²³ atoms.

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms.

From the above concept, 1 mole of sodium also contains 6.02×10²³ atoms.

1 mole of sodium = 23 g.

Thus,

23 g of sodium contains 6.02×10²³ atoms.

Therefore, 4.5 g of sodium will contain = (4.5 × 6.02×10²³)/23 = 1.18×10²³ atoms.

From the above calculation,

4.5 g of sodium contains 1.18×10²³ atoms.

What are the names of the following three compounds (see attached)
balu736 [363]

Answer:

1. 4-ethyl-1-heptene

2. 6-ethyl-2-octene

3. 1-butyne

Explanation:

The compounds are named according to IUPAC rules.

Compound 1:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 7 carbon atoms, so taken the name hept.
  • The double bond between C1 and C2, so take no. 1 and add the suffix ene to hept "1-heptene".
  • The ethyl group is the alkyl substituent on position 4.
  • So the name is 4-ethyl-1-heptene.

Compound 2:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain).
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (double has the priority over alkyl substituents).
  • The longest chain contains 8 carbon atoms, so taken the name oct.
  • The double bond between C2 and C3, so take no. 2 and add the suffix ene to oct "2-octene".
  • The ethyl group is the alkyl substituent on position 6.
  • So the name is 6-ethyl-2-octene.

Compound 3:

  • Identify the longest carbon chain. This chain is called the parent chain.
  • Identify all of the substituents (groups appending from the parent chain), there is no substituents.
  • The parent chain is numbered so that the multiple bonds have the lowest numbers (Triple bond here take the lowest number).
  • The longest chain contains 4 carbon atoms, so taken the name but.
  • The triple bond between C1 and C2, so take no. 1 and add the suffix yne to but "1-butyne".
  • So the name is 1-butyne.

Chemistry what is stoichiometry and the different formulas
USPshnik [31]
Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. Hoped this helped!!!!. Also if you are trying to look for the formulas it should be online just type in stoichometry formulas.
