contrast longitudinal and transverse waves by describing the particle movement in sound and water waves :​
Airida [17]

Answer: In a transverse wave, the particles of the medium move perpendicular to the wave's direction of travel. Transverse waves are characterized by peaks and valleys, called crests and troughs. In a longitudinal wave, the particles of the medium move parallel to the wave's direction of travel.

Romashka [77]

Answer:

30 μmol/L

Explanation:

<em>A chemist prepares a solution of barium chloride by measuring out 8.9 μmol of barium chloride into a 300mL volumetric flask and filling the flask to the mark with water. </em>

<em> Calculate the concentration in μmol L of the chemist's barium chloride solution. Round your answer to 2 significant digits.</em>

<em />

The chemist has 8.9 μmol of solute (barium chloride) and he adds water until the mark of 300 mL in the container, which is the volume of the solution. We will need the conversion factor 1 L = 1000 mL. The concentration of barium chloride in μmol/L is:

\frac{8.9\mu mol}{300mL} .\frac{1000mL}{1L} =30\mu mol/L

Nitrogen monoxide reacts with chlorine at high temperature according to the equation, 2 NO(g) + Cl2(g) → 2 NOCl(g) In a certain
FrozenT [24]

Answer:

4.50 × 10⁻⁴ mol L⁻¹ s⁻¹

Explanation:

Step 1: Write the balanced equation

2 NO(g) + Cl₂(g) → 2 NOCl(g)

Step 2: Establish the appropriate molar ratio

The molar ratio of NO(g) to NOCl(g) is 2:2, that is, when 2 moles of NO(g) are consumed, 2 moles of NOCl(g) are formed.

Step 3: Calculate the rate of consumption of NO(g)

The rate of formation of NOCl(g) is 4.50 × 10⁻⁴ mol L⁻¹ s⁻¹. The rate of consumption of NO(g) is:

\frac{4.50 \times 10^{-4}molNOCl}{L.s} \times \frac{2molNO}{2molNOCl} = \frac{4.50 \times 10^{-4}molNO}{L.s}
