How can you tell S-wave arrival from the end of the P-wave?
Margarita [4]

Answer:

<h2>The P wave will be the first wiggle that is bigger than the rest of the little ones (the microseisms). Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves</h2>

4) A granola bar has a mass of 42.9 g and the granola bar contains 26.20% honey
nata0808 [166]

<u>Answer:</u>

The percentage of honey in one granola bar is 26.02 percent.  

<u>Explanation:</u>

The weight of 1 granola bar is 42.9 grams. The grams of honey that is present in one granola bar is equal to 26.02 percent of 42.9 = 11.16 g

Now the amount of honey in the factory is given as 189.5g the weight of total granola bars would be

                                     = 42.9/11.16 x 189.5= 728.25

So no. of granula bars =728.25/42.9 =16.9 that can be Approximated to nearly 17

Now if one box has 6 bars then 17 bars will have to fit inside three boxes

Freon, a very useful refrigerant, is produced in the following reaction:
Svetach [21]

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

  • CCl₄: 3 moles  
  • SbF₃: 2 moles
  • CCl₂F₂: 3 moles
  • SbCl₃: 2 moles

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

moles of antimony trifluoride=\frac{3*10^{6}  moles of freon*2 moles of antimony trifluoride}{3 moles of freon}

moles of antimony trifluoride= 2*10⁶

<u><em>The chemistry will need 2*10⁶ moles of antimony trifluoride.</em></u>
