how does increasing concentration/ temperature/ surface area affect the yield of products in a chemical reaction (not reversible
egoroff_w [7]
Answer:
             <span>Increasing concentration, temperature and surface area will increase the yield of products.

Explanation:
                   Concentration:
                                           
Increase in concentration of reactants will increase the number of reactants per unit volume. Therefore, the probability of collisions will increase hence, it will result in the increase in yield.

                   Temperature:
                                        Increase in temperature increases the kinetic energy of reactants. Therefore, the increase in velocity of reactants results in the collisions with high energy. It makes it feasible for reactants to attain the optimum energy (activation energy) to convert into products with good yield.

                  Surface Area:
                                       The reactants in grinded / powder form reacts fast as compared to solid form. In fact, grinding results in increase of the surface area of reactants. Greater surface area increases the probability of reactants to colloid. Hence, increases the yield.</span>

A sound wave is traveling at 331 m/s and has a frequency of 126 Hz. What is the wavelength?​
damaskus [11]
<h2>Answer</h2>

2.626984127 m

<h2>Explanation:</h2><h2></h2>

You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).

v = f x λ

where:

v = velocity

f = frequency

λ = Wavelength

Rearrange to make λ subject:

λ = v / f

We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:

331 / 126 = 2.626984127 m
