What do 4 hydrogen and 2 oxygen atoms chemically react to

Chemistry

Answer:

2 molecules of water

Explanation:

In chemical reactions, molecules and compounds chemically combine to give products. This involves atoms combining by re-establishing bonding relationships.

  4 hydrogen atoms is equivalent to 2 molecules of Hydrogen gas = H₂

   2 oxygen atoms is the same as 1 oxygen molecule  = O₂

This 2 molecules of hydrogen gas and 1 molecule of O₂ gas will combine to form 2 molecules of water chemically;

                        2H₂   + O₂    →  2H₂O

galben [10]

Answer:

Explanation:

From the equation:

H2SO4(aq) + 2NaOH(aq) --> Na2SO4(aq) + 2H2O (l)

<em>1 mole of the acid (H2SO4) and 2 moles of the base (NaOH) are required for complete neutralization.</em>

mole of acid (H2SO4) present = molarity x volume

                                  = 1 x 0.1 = 0.1 mole

Mole of base (NaOH)  present = mass/molar mass

                                                      = 7/40 = 0.175 mole

<em>The ratio of acid and base should be 1:2, hence the acid is slightly excessive in this case and the base is the limiting reagent that will determine the extent of the reaction.</em>

Amount of excess acid = 0.1 - 0.175/2

                                       = 0.0125 mole

volume of excess acid = mole/molarity

                                      = 0.0125 x 1 = 0.0125 L

                                       = 12.5 mL

<em>Hence, the acid (H2SO4) was in excess by 12.5 mL.</em>

a solution with a transmittance of 0.44 is analyzed in a spectrophotometer with 6% stray light. calculate the absorbance reporte
IgorLugansk [536]

The absorbance reported by the defective instrument was 0.3933.

Absorbance A = - log₁₀ T

Tm = transmittance measured by spectrophotometer

Tm = 0.44

Absorbance reported in this equipment = -log₁₀ (0.44) = 0.35654

True absorbance can be calculated by true transmittance, Tm = T+S(α-T)

S = fraction of stray light = 6%= 6/100 = 0.06

α= 1, ideal case

T = true transmittance of the sample

Tm = T+S(α-T)

now, T= Tm-S/ 1-S = 0.44-0.06/ 1-0.06 = 0.404233

therefore, actual reading measured is A = -log₁₀ T = -log₁₀ (0.404233)

i.e; 0.3933

Which of these is a property of acids?
sertanlavr [38]

Answer: Correct option is 3.

Explanation: Properties of Acid:

  • They are liquids.
  • Acids are the ones which donate hydrogen ions to the solution.
  • They turn blue litmus paper to red.
  • They are corrosive in nature.
  • They are sour in taste. For example: vinegar

From the above properties written, it can be said that option 3 is correct.

Ethyl alcohol has a heat of vaporization of 850. J/g. What mass of ethyl alcohol can be boiled using 15000 J of energy?
Verdich [7]
The amount of heat, H, needed to boil off certain mass, m, of the substance is given by the equation,
                                H = mHv
where Hv is the heat of vaporization. Manipulating the equation, the mass is calculated by,
                                m = H/Hv
Substituting the known values,
                                m = 15000 J/(850 J/g) = 17.65 g
Thus, the mass of ethyl alcohol is approximately 17.65 g.
