Consider the reaction H2SO4 + 2 NaOH -> Na2SO4 + 2H2O. In an acid-base tritration, the stoichiometric point happens when 43.4

4 mL of 0.2753 M NaOH is added to a 54.69 mL portion of H2SO4. What is the molar concentration of H2SO4 expressed in M?

            moles NaOH = c · V = 0.2753 mmol/mL · 43.44 mL = 11.959032 mmol
            moles H2SO4 = 11.959032 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 5.979516 mmol
Hence
            [H2SO4]= n/V = 5.979516 mmol / 54.69 mL = 0.1093 M
The answer to this question is  [H2SO4] = 0.1093 M

The quantity of heat required to change the temperature of 1 g of a substance by 1⁰c is defined as
Alex
Specific heat is the quantity of heat required to change the temperature of 1 gram of a substance by 1 degree Celsius. It is the amount per unit mass that is required to raise the temperature by one degree Celsius. Every substance has its own specific heat and each has its own distinct value. The units of specific heat are joules per gram-degree Celsius (J/f C) and sometimes J/Kg K may also be used.

How are concentration and chemical reaction rate related?
dem82 [27]

Answer:

When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

Sediment layers stop lateral spreading when:
GREYUIT [131]
Sediment layers stop lateral spreading when they encounter a barrier and they run out of additional sedimentary material. Lateral spreading is the lateral movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. Hope this answers the question.
