From the given pH, we calculate the concentration of H+:
     [H+] = 10^-pH = 10^-5.5
We then use the volume to solve for the number of moles of H+:
     moles H+ = 10^-5.5M * 4.3x10^9 L =  13598 moles
From the balanced equation of the neutralization of hydrogen ion by limestone written as
     CaCO3(s) + 2H+(aq)  → Ca2+(aq) + H2CO3(aq)
we use the mole ratio of limestone CaCO3 and H+ from their coefficients, which is 1 mole of CaCO3 is to react with 2 moles of H+, to compute for the mass of the limestone:
     mass CaCO3 = 13598mol H+(1mol CaCO3/2mol H+)
                               (100.0869g CaCO3/1mol CaCO3)(1kg/1000g) 
                            = 680 kg

QUESTION 14
AveGali [126]

Within each functional group, the boiling points of members of the group vary according to molecular weight. Therefore, one cannot deduce any functional group from boiling points.

Organic compounds are divided into families called homologous series. Each homologous series has a functional group common to all the members of the series. As a result of this, the chemical properties of all the members of the homologous series are similar.

However, the boiling points of the members of a homologous series vary according the their molecular weights. As such, boiling points can not be used as evidence to classify substances into any particular homologous series.

Summarily, one cannot deduce any functional group from physical properties.

Answer: The Note

Explanation: Neurotransmitters are endogenous chemical substances that transmits signals through a NEUROMUSCULAR JUNCTIONS.

The signals are transmit from one NERVE CELL TO THE TARGET POINT such as Muscle cell,gland cell etc. Neurotransmissiom require the presence of synapse(the structure or medium through which neurosignals which can be an electrical or chemical signals to pass through).

Determine the balanced chemical equation for this reaction.C8H18(g) O2(g)→CO2(g) H2O(g)Enter the coefficients for each compound
sashaice [31]

Answer:

2C₈H₁₈(g) + 25O₂(g)→16CO₂(g) + 18H₂O

Explanation:

To balance an equation, the moles of one element on one side of the equation should be the same as those on the other side of the equation. This is because (as a law of thermodynamics), in a chemical reaction, the matter is not destroyed nor created - atoms are only rearranged.
