Which is an example of a double
replacement reaction?
2Na+ Cl2 + 2NaCl
H2SO3 → H20 + S02
2K + 2H20 – 2KOH + H2
NaCl + AgF-NaF + AgCI

Answers

Answer:

NaCl + AgF → NaF + AgCl

Explanation:

A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products.

From all the reactions given ,

2Na + Cl₂ → 2NaCl is an example of combination reaction because two or more reactants (Na & Cl₂) react with each other to form a single product (NaCl)H₂SO₃ → H₂O + SO₂ is an example of decomposition reaction because a single reactant (H₂SO₃) breaks down into two or more products (H₂O & SO₂).2K + 2H₂O → 2KOH + H₂ is an example of displacement reaction because a highly reactive element (K) displaces a least reactive element (H) from its compound (H₂O).NaCl + AgF → NaF + AgCl is an example of double replacement reaction because there's an exchange between Cations ([tex]Na^+[/tex] & [tex]Ag^{+}[/tex]) and Anions ([tex]Cl^-[/tex] & [tex]F^-[/tex]).

When an atom of calcium (Ca) forms an ion by losing two electrons, what is the ion’s type and charge?

cation, 2+

anion, 2−

cation, 2−

anion, 2+

Answers

Answer:

cation +2

Explanation:

A cation is a positively charged ion, while an anion is a negatively charged ion. Contrary to how it sounds, when an atom loses electrons, it's charge becomes more positive. Since the calcium atom lost 2 electrons, it is a positive (+2) ion.

The electrical charge of the calcium ion is +2.

A chemistry student experiments on producing table salt by reacting pure sodium cubes with confined chlorine gas. If the procedure is successful, how much salt is produced with 160 g of chlorine gas used? *
with solution pls

Answers

Answer: 263 grams of salt is produced.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Cl_2=\frac{160g}{71g/mol}=2.25moles[/tex]

The balanced chemical reaction is:

[tex]2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)[/tex]

According to stoichiometry :

1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]

Thus 2.25 moles of [tex]Cl_2[/tex] will produce =[tex]\frac{2}{1}\times 2.25=4.50moles[/tex] of [tex]NaCl[/tex]

Mass of [tex]NaCl=moles\times {\text {Molar mass}}=4.50moles\times 58.5g/mol=263g[/tex]

Thus 263 grams of salt is produced.
