Answer:
            <span>When baking soda is mixed with vinegar, a Neutralization reaction takes place.

Explanation:
                   The reaction of Baking sode (NaHCO</span>₃) and Vinegar (Acetic Acid) takes place in two steps.

Step 1:
           In first step a Double Displacement Reaction takes place between baking soda and acetic acid.

               NaHCO₃  +  CH₃COOH    →    CH₃COONa  +  H₂CO₃

Step 2:
           The Carbonic acid (H₂CO₃) formed in first step undergoes Decomposition Reaction as it is unstable.

                                 H₂CO₃     →      CO₂    +    H₂O

How many moles of Fe2+ are there in a 2.0g sample that is 80% by mass of FeCl2?
KIM [24]

Answer:

A walkthrough for a sample titration calculation for all levels of chemistry. ... Now that gives us the moles of Fe2+, but it's asking for how many grams there are. ... The molar mass of iron is about 55.8, so we'll just put that.

Nitrogen and hydrogen combine to form ammonia in the Haber process. Calculate (in kJ) the standard enthalpy change ΔH° for the r
PolarNik [594]

Answer: -105 kJ

Explanation:-

The balanced chemical reaction is,

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

The expression for enthalpy change is,

\Delta H=\sum [n\times B.E(reactant)]-\sum [n\times B.E(product)]

\Delta H=[(n_{N_2}\times B.E_{N_2})+(n_{H_2}\times B.E_{H_2}) ]-[(n_{NH_3}\times B.E_{NH_3})]

\Delta H=[(n_{N_2}\times B.E_{N\equiv N})+(n_{H_2}\times B.E_{H-H}) ]-[(n_{NH_3}\times 3\times B.E_{N-H})]

where,

n = number of moles

Now put all the given values in this expression, we get

\Delta H=[(1\times 945)+(3\times 432)]-[(2\times 3\times 391)]

Delta H=-105kJ

Therefore, the enthalpy change for this reaction is, -105 kJ

We observe a distant object in space and see that the spectral lines for hydrogen in the object's light appear at a shorter wave
MrMuchimi

Answer:

This tells us the radial velocity of the object and that the object is approaching or coming towards us.

Explanation:

Certain chemicals radiate with particular wavelengths or colors  when their temperature is raised or when they are charged electrically. Also observable are dark strokes separating the spectrum known as absorption lines

These spectral lines of chemicals are well known as stated above and from the phenomenon of Doppler effect, spectroscopy can be used to detect the movement of a distant object by the change of the emitted frequency of the wavelength

The Doppler effect is used in calculating the radial velocity of a distant object due to the fact that an approaching object compresses its emitted signal wavelength while a receding object has a longer wavelength than normal

What is the mass number of an atom with 17 protons, 17 electrons, and 20 neutrons?
astra-53 [7]
The mass number of this particular element is 37

An element with 17 protons will ALWAYS be chlorine.
The mass number is found by adding the element’s protons and neutrons.
protons+neutrons=mass number

Here is the math if needed,
17+20=37

Therefore the mass number is 37

I hope this helped!
