How many moles are in 5.77 grams of calcium

Chemistry
1 answer:
AnnyKZ [126]2 years ago
8 0

  • The number of moles  that are in 5.77 grams of calcium  is (8.677*10^{22})

  • From periodic table, <em>Avogadro's number of atom of calcium has a mass approximately ( 40.1 g)</em>

Given:

  • Mass of calcium= 5.77 grams

  • Number of calcium atom =  \frac{5.77g}{40.1g} × ( Avogadro's number)

(Avogadro's number= 6.022 × 10^23 mol^{-1}

Number of calcium atom= \frac{5.77g}{40.01g}× 6.022 × 10^{23} mol^{-1}

= 8.677× 6.022 10^{22}

Therefore, number of moles  that are in 5.77 grams of calcium  is (8.677 × 10^22)

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

Predict the products and write the balanced chemical equation for this reaction. Include the physical state of the product(s).
sukhopar [10]

Answer:

Al(C2H3O2)3 (aq) + 3AgNO3 (aq) ------>Al(NO3)3(aq) + 3Ag(C2H3O2)(s)

Explanation:

A chemical reaction refers to an interaction between two or more chemical species that leads to the formation of other new chemical species.

There are many types of chemical reactions. The type shown above is called a double replacement reaction. In this type of reaction, ions exchange partners in the product.

A chemical reaction is said to be balanced when the number of atoms of each element on the left hand and right hand sides of the reaction equation are exactly the same.

What is the difference between polar and non-polar
ExtremeBDS [4]

Answer:

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Explanation:

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
