Que cantidad de agua sera necesaria agregar a 25 gramos de sulfato de cobre II para preparar una solución al 15% m/m?
Answer:
141.7 de Agua deben ser adicionados para preparar la solución deseada
Explanation:
El %m/m se define como la masa de soluto (En este caso, sulfato de cobre) en 100g de solución (Sulfato de cobre + Agua):
%m/m = Masa soluto / Masa soluto + Masa Agua *100
Reemplazando con los datos del problema:
15%m/m: 25g CuSO₄ / (25g CuSO₄ + Xg H₂O) * 100
0.15 = 25 /(25+X)
3.75 + 0.15X = 25
0.15X = 21.25
X = 141.7 de Agua deben ser adicionados para preparar la solución deseada
Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.
HELpPPPPppp!!!!!! will mark brainless
Answer:
A
Explanation:
This is because in the graph shown line A has a quite greater impact of refraction than line B .
Hence, we can conclude that line A has the greater reaction at a faster rate.

Al(s) + NiSO4(aq)
Balance
Answer:
[tex]2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni[/tex]
Explanation:
This reaction type is a single replacement. The format of a single replacement is:
[tex]A+BC --> B+AC[/tex]
A= Al
B= Ni
C= SO
The coefficient 3 for Ni would become a subscript for AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2
How many grams of carbon dioxide would 6.0E25 molecules be?
Answer:
4383.28 g
Explanation:
First we'll need to convert molecules into moles, we can do so using Avogadro's number:
6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 molesThen we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:
99.62 moles CO₂ * 44 g/mol = 4383.28 gQuestion 17
