Explanation:
as a solution of copper sulfate slowly evaporates, beautiful blue crystals made of cu(ii) and sulfate ions form such that water molecules are trapped inside the crystals. the overall formula of the compound is cuso4 • 5h2o.
There are five molecules of the water of crystallization.
Mass of hydrated copper(II) sulfate CuSO4 · xH2O = 0.755 g
Mass of anhydrous copper(II) sulfate CuSO4 = 0.483 g
Molar mass of hydrated copper(II) sulfate CuSO4 · xH2O = (160 + 18x) g/mol
Molar mass of anhydrous copper(II) sulfate CuSO4 =160 g/mol
Number of moles of hydrated copper(II) sulfate CuSO4 · xH2O = Number of moles of anhydrous copper(II) sulfate CuSO4
Therefore;
0.755 g/(160 + 18x) g/mol = 0.483 g/160 g/mol
0.755 * 160 = 0.483 (160 + 18x)
120.8 = 77.28 * 8.694x
120.8 - 77.28 = 8.694x
x = (120.8 - 77.28)/8.694
x = 5
The formula of the hydrated salt is CuSO4 · 5H2O.

What is a court?Plessy v. Ferguson was a landmark 1896 Supreme Court decision that upheld the legality of racial segregation under the "separate but equal" principle. The case began in 1892, when African-American railroad traveler Homer Plessy refused to ride in a vehicle reserved for blacks.
The Supreme Court rejected Plessy's claim that his protected rights were violated, ruling that legislation that "implies only a juridical disparity" between whites and blacks was not unlawful. As a result, Jim Crow laws and segregated open lodging based on race became popular.

Answer:
D is the correct answer- ¿Qué es lo que está comiendo el duque?
The translation of the given question is: ¿Qué es lo que está comiendo el duque?
What is translation?
Translation is the conveyance of a source-language text's meaning through an equivalent target-language text. The English language makes a terminological distinction between translating and interpreting; translation can begin only after writing appears within a language group. A translator always runs the danger of introducing source-language terms, grammar, or syntax into the target-language translation inadvertently. Such "spill-overs," on the other hand, have occasionally imported useful source-language calques and loanwords that have enhanced destination languages. Translators, notably early sacred text translators, have contributed form the languages into which they have translated. Because of the difficulty of the translation process, efforts have been made, with varied degrees of success, since the 1940s to automate translation or to mechanically assist the human translator. More recently, the Internet's emergence has created a global market for translation services and promoted "language localisation."

if 3.00 g g of titanium metal is reacted with 6.00 g g of chlorine gas, cl2 c l 2 , to form 7.7 g g of titanium (iv) chloride in a combination reaction, what is the percent yield of the product?
The percentage yield of titanium IV chloride is 95.8%.
The equation of the reaction is;
Ti(s) + 2Cl2(g) ------> TiCl4(s)
Number of moles of Ti = 3.00 g /48 g/mol = 0.0625 moles
Number of moles of Cl2 = 6.00 g/71 g/mol = 0.0845 moles
The limiting reactant yields the least amount of product.
For Ti, the reaction is 1:1 so it yields 0.0625 moles of TiCl4
For Cl2;
2 moles of Cl2 yields 1 mole of TiCl4
0.0845 moles of Cl2 yields 0.0845 moles × 1 mole/2 moles = 0.0423 moles of TiCl4
Hence, Cl2 is the limiting reactant.
Mass of TiCl4 produced = 0.0423 moles × 190 g/mol = 8.037 g
Note that 190 g/mol is the molar mass of TiCl2 and 8.037 g is the theoretical yield of the compound.
Applying the formula;
%yield = actual yield/theoretical yield × 100/1
In the question, the actual yield was supplied as 7.7 g.
%yield =7.7 g/8.037 g × 100/1
%yield = 95.8%

Answer:
F= 11.76 kn
Explanation:
The rocket engines apply a constant upward force of 15680 N.
What is force?Force can be said as the amount of pressure that is applied ob an object. One can easily determine the mass and the velocity to find the force that is applied to an object.
Gravitational acceleration which will be represented by g = 9.8 m/s2
Mass of the rocket which will be represented by M = 400 kg
Constant upward force that is applied on the engine of the rocket which will be represented by F
The height through which engines accelerate the upward force upon the rocket will be represented by h = 100 m
Work done by the engine which will be represented by W
W = Fh
Maximum height well above the surface, this data will represent the rocket reaches which will be represented by H
The work completed with the help of the engine on the rocket is equal to the potential energy gained with respect to maximum height.
W = MgH
Fh = MgH
F(100) = (400)*(9.8)*(400)
