Answer: single covalent bond
Explanation: Chlorine is a simple molecule. each chlorine atom can count 8 electrons in its outer shell. with other chlorine atoms. One pair of shared electrons form a single covalent bond.
Answer:C
Explanation:it gets rid of waste
Answer:
2 HCl + CaCO3 = CaCl2 + H2O + CO2
Explanation:
On the right side we have 2xCl, to get the same amount we will multiply HCl on the left side by 2.
This will give us 2xH on the left side; we also have 2xH on the right side ( in H2O).
On both sides we have 1x Ca; 1x C.
On the left side we have 3XO (in CaCO3), on the right side we have 1O in H20 and 2xO in CO2, so 3x O on the right side as well.
The reaction is balanced.
Answer:
4.89 mol
Explanation:
Step 1: Write the balanced equation
This is a double displacement reaction.
3 CaSO₄ + 2 AIP ⇒ Ca₃P₂ + AI₂(SO₄)₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CaSO₄ to AlP is 3:2.
Step 3: Calculate the moles of AlP needed to react with 7.33 moles of CaSO₄
We will use the previously established molar ratio.
7.33 mol CaSO₄ × 2 mol AlP/3 mol CaSO₄ = 4.89 mol AlP
