How does changing the number of electrons in an atom affect the atom?

Chemistry

Gre4nikov [31]2 years ago

In addition to protons and neutrons, all atoms have electrons, negatively charged particles that move around in the space surrounding the positively-charged nuclear core. But unlike protons, the number of electrons can and does change without affecting the kind of element an atom is!

Write a balanced chemical equation for the reaction of copper(II) sulfate and concentrated ammonia to produce teramine copper(II
Rudiy27

Answer:

CuSO4(aq) + 4NH3(aq) + nH2O→ [Cu(NH3)4H2On]S04(aq)

Explanation:

When the concentrated ammonia is added into the copper ions solution, a blue solid is formed. This blue solid is gelatinous.it consist of Cu(OH)2 in insoluble form. As more ammonia is added precipitate start to dissolve and [Cu(NH3)4]∧+2 is produce.

Net Ionic equation:

Cu∧+2 +4NH3 →  [Cu(NH3)4]∧+2

S04∧-2 are spectator ions.

Properties and uses of Tetraaminecopper(ll) sulfate:

1. It is solid compound.

2. Its color is dark blue.

3. It has ammonia like odor.

4. It is used to make the copper compounds and also used in the printing of fabric.

5. It is also used as pesticide.

If 200 grams of glucose is converted what will the total mass of ethanol and carbon dioxide be
lubasha [3.4K]
Glucose can be converted into ethanol, carbon dioxide and energy (usually in the form of heat).

Using chemical formulas, this can be illustrated as follows:
Glucose = Ethanol + Carbon Dioxide + Energy
C6H12O6 = 2C2H5OH + 2CO2 + Energy

From the periodic table:
molecular mass of carbon = 12 grams
molecular mass of oxygen = 16 grams
molecular mass of hydrogen = 1 gram

Therefore:
molar mass of glucose = 6(12) + 12(1) + 6(16) = 180 grams
molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46 grams
molar mass of carbon dioxide = 1(12) + 2(16) = 44 grams

Based on the conversion equation, each one mole of glucose converts into two moles of ethanol and two moles of carbon dioxide.
Therefore, each 180 grams of glucose converts into 46 x 2 = 92 grams of ethanol and 44 x 2 = 88 grams of carbon dioxide in addition to energy.

To calculate the mass of ethanol and carbon dioxide produced from 200 grams of glucose, we will simply use cross multiplication as follows:
mass of ethanol = (200 x 92) / 180 = 102.2 grams
mass of carbon dioxide = (200 x 88) / 180 = 97.7 grams

Total mass of ethanol and carbon dioxide = 102.2 + 97.7 = 199.9 grams
