The reaction that would beat represent a typical reaction mechanism is when A and B react with each other to produce certain products.
The volume of your 0.25 m stock solution that is needed to make 200 ml of 0.010 m NaCl is <u>0.008 L</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
Calculation:-
C₁ = 0.25 M
V₁ = ?
C₂ = 0.010 M
V₂ = 200 ml = 0.2 L
V₁ = C₂V₂/C₁
= 0.010 × 0.2 / 0.25
=<u> 0.008 L</u>
The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.

C. both sources of energy rely on water.
Explanation:
Hydroelectricity and tidal energy are similar energy sources because they both rely on water.
They harness the power of moving water to produce their energy.
- Tidal energy is the energy derived from moving water as crashing waves in an ocean.
- Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
- They are both renewable energy sources.
