Answer:

<h2>Longitudinal Waves.</h2>

Explanation:

There are two types of waves: longitudinal and transversal waves.

Longitudinal waves are those where the oscillation and propagation have the same direction, for example, a spring have its oscillation in the same direction of the propagation. This means that both directions are parallel.

On the other hand, transversal waves have these directions differently, like ocean's waves, particles move up and down, while the waves is propagating forward or backwards, this means that both direction are perpendicular.

Hello.

<span>It makes a longitudinal wave because it stretches and compresses while as it slithers foward.

consider the following equilibrium:h2co3(aq) h2o(l) h3o (aq) hco3-1(aq).what is the correct equilibrium expression?
MAVERICK [17]

The equilibrium expression shows the ratio between products and reactants. This expression is equal to the concentration of the products raised to its coefficient divided by the concentration of the reactants raised to its coefficient. The correct equilibrium expression for the given reaction is:<span>

<span>H2CO3(aq) + H2O(l) = H3O+(aq) + HCO3-1(aq)

Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>

Is it possible for the equivalence point of a titration to not be at pH 7? Explain your answer.
lara31 [8.8K]
<span>The reason it will be 7 for some titrations is that when you  titrates a strong acid with a strong base for example  HCl and NaOH the salt formed is conjugate base of strong acid and will be a very weak base
 That means that it cannot produce any OH^-1 and all the H+ has been converted to water.The only source of H+ or OH is water with a Ka of 10^-14 so the pH = -log [H+]=-log 10^-7 = 7 
second reason is 
When you titrates a weak acid with strong base at equivalence point 
only a water solution of the conjugate base exists 

CH3COOH + NaOH ----- Na+ CH3COO^-1 + H2O 
Since the conjugate base is the conjugate base of a weak acid it will hydrolyze in water like so 
for instance Na+ CH3COO^-1 + HCl---- CH3COOH + NaCl the equivalence point will be way BELOW 7 and in the case of above will be less than 5. So pH of 7 at equivalence point is only reached in strong acid strong base titrations.
hope this helps</span>

6) A student measures out 96.21 g of sulfur for an experiment. How many moles of Sulfur are in this
barxatty [35]

Atomic mass of Sulfur = 32g

32g of Sulfur is one mole.

1g of Sulfur is \frac{1}{32} moles

96.21g of Sulfur is \frac{96.21}{32} moles=> 3moles(appx)
