A useful dilution relationship is (M1V1)=(M2V2) where M is molarity and V is volume in liters.
(6.00M x V1) = (2.00M x .500L) (I assume you mean 2.0M)
V1= (2.00M x .500L)/6.00M
V1= 0.167L
Answer:
Ionic
Explanation:
Any metal with a nonmetal is an ionic bond due to the transfer of electrons.
A food web shows all of the possible energy pathways through an ecosystem.
Answer: A. Metalloids exhibit properties of both metals and nonmetals
Explanation: Metalloids are elements that has a metallic appearance such as shiny, dull amd ductile but they possess the properties of nonmetals in which they are intermediately poor conductors of heat and electricity in which they are good semiconductors.

Answer:</h3>
825 mL
<h3>
Explanation:</h3>
<u>We are given;</u>
- Molarity of HCl is 0.200 M
- Mass of CaCO₃ is 8.25 g
- The equation of the reaction as;
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
We are required to calculate the volume of the Acid that reacted.
<h3>Step 1: Determine the moles of CaCO₃ that reacted;</h3>
We know that;
Moles = Mass ÷ molar mass
Molar mass CaCO₃ is 100.1 g/mol
Therefore;
Moles of CaCO₃ = 8.25 g ÷ 100.1 g/mol
= 0.0824 moles
<h3>Step 2: Determine the moles of HCl that reacted;</h3>
From the reaction, 1 mole of CaCO₃ reacts with 2 moles of HCl
Therefore;
Moles of HCl = Moles of CaCO₃ × 2
= 0.0824 moles × 2
= 0.1648 moles
= 0.165 moles
<h3>Step 3: Determine the volume of HCl </h3>
We know that, Molarity = Moles ÷ Volume
Rearranging the formula;
Volume = Moles ÷ Molarity
Therefore;
Volume of HCl = 0.165 moles ÷ 0.200M
= 0.825 L
But, 1 L = 1000 mL
= 825 mL
Therefore, the volume of HCl that reacted with CaCO₃ 825 mL
