The speed of sound in water is 350m/s. If a sound wave has the frequency of 50Hz.
Elena-2011 [213]

Answer:

Explanation

Let, Wavelength = W,

Given, frequency (f) = 50 Hz, wave velocity (V) = 342 m/s

We know, V = f × W

=> 342 = 50 × W

=> W = 342/50 metre

=> W = 6.84 metre

Write a paragraph explaining the effect of surface area on the rate of reaction.
nexus9112 [7]
(For a bit of context I will use the reaction between HCl and Mg as an example)

The larger the surface area of the magnesium metal, the more particles are exposed to collide with the aqueous HCl particles to cause the reaction to occur. This increases the frequency per second of collisions, speeding up the rate of reaction.

The effect of a catalyst is to reduce the minimum collision energy which allows the reaction to happen. This does not increase the number of collisions per second, but increases the percentage of successful collisions, which consequently causes the rate of reaction to increase .

I have drawn diagrams showing the effect of surface area, but there isn't really a meaningful diagram that I know of to show the impact of a catalyst (at least not at GCSE level).

Select the chiral center(s) in threonine by clicking on the atom(s). (clicking on an atom will turn it green. if you make a mist
Alborosie

Chiral center is the center where all the attached substituents are different. For example, a carbon is said to be chiral carbon if it is attached to four different substituents.

The structure of threonine is attached here.

The marked carbons are chiral carbons because they have all the 4 different substituents.

He shell of a chicken’s egg makes up 5% of the mass of an average egg. An average egg has a
blagie [28]
First of all, you have to write a balance equation for the reaction. The balanced equation for the reaction is:
CaCO3 + 2CH3COOH = [CH3COO]2Ca +CO2 + H20
Next, find the mass of the shell.
For an average egg, the mass is 0.05 * 50 = 2.5 g. 
To convert this mass to moles, we have: 2.5/100 = 0.025 Moles. This is the mole of calcium carbonate.
To calculate the mole of ethanolic acid, we have: 50 * 0.001 * 2 = 0.1. This value is for 2 molecules, therefore for one molecule, we have: 0.1/2 = 0.05. 
From the equation of reaction, one mole of calcium carbonate is required to neutralize two moles of ethanolic acid.
Thus, 0.05/0.025 = 2. This imply that two complete egg shells will be needed to neutralize 50cm of ethanolic acid.
