Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100.. 49.7% 58.4% 63.6% 78.7%

Answers

Answer 1

Answer:

D. 78.7% on edge 2020

Explanation:

i got 100

Answer 2

The percent yield of NaCl is 78.7 %

CuCl₂  +  2NaNO₃ →  Cu(NO₃)₂  + 2NaCl

How NaNO₃ is determined to be in excess?

If the NaNO₃ is determined to be in excess, the limiting reagent is the chloride. We convert the mass to moles:

31 g . 1mol / 134.45g = 0.230 moles

Ratio is 1:2, so we can make a rule of three to determine the theoretical yield

1 mol of copper (II) chloride reacts to produce 2 moles of sodium chloride.

Then you can find out how much NaCl 31.0g of CuCl₂ should produce using stoichiometry.  Divide 31.0g by the molar mass of CuCl₂ (134.446g/mol) to get 0.2306mol CuCl₂.  Than multiply 0.2306mol CuCl₂ by 2 to get 0.4612mol NaCl.  

Than multiply 0.4612mol by the molar mass of NaCl (58.45g/mol) to get 26.95g of NaCl.

that means that 100% yield would give you 26.95g of NaCl so to find percent yield divide 21.2 by 26.95 to get 0.7867 which is 78.7% yield

Then, 0.230 moles of CuCl₂ will react to produce (0.230 .2) /1 ) = 0.461 moles of NaCl → we convert the moles to mass → 0.461 mol . 58.45 g / 1mol = 26.9 g

To find percent yield we do → (Yield produced / Theoretical yield) . 100

(21.2 g / 26.9 g) . 100 = 78.7 %

The information that the dialogue revealed was that the guards do not recognize each other at first.

From the complete question, we can deduce that the guards didn't recognize each other at first. Bernardo didn't see Francisco properly at first and he thought that he was the king before he saw him clearly.

A dialogue simply refers to a conversation between two to more people. The effect of the dialogue was that it caused a feeling of confusion and distrust. Bernardo and Francisco were confused.

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?

Answers

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%

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)

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."

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.

Answers

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.
