Which one of the following would form a precipitate when mixed with LiOH?

A) KNO3
B) NH4Cl
C) Ca(C2H3O2)2
D) ZnBr2

Answers

Answer:

ZnBr2

Explanation:

KNO3 + LiOH -------> no reaction

This is because KNO3 and LiOH completely ionize.in water and form neutral solutions.Since both are neutral no reaction occurs

NH4Cl + LiOH -----> NH3 (aq) + H2O (l) + LiCl(aq)

None of the above products are precipitates

Ca(C2H3O2)2 + 2LiOH -----> Ca(OH)2 (aq) + 2LiC2H3O2 (aq)

ZnBr2 + 2LiOH -----> Zn(OH)2 (s) + LiBr2 ( aq)

Zn(OH)2 thus formed is a white precipitate

However when excess LiOH is added Zn(OH)2 precipitate will dissolve to give a clear solution of Li2ZnO2 .

You can remember this by the fact that Na,K,Rb,Cs,Ca,Sr,Ba hydroxides are soluble in water and all other hydroxide are precipitated in water

Zn(OH)2 (s) + 2 LiOH ------> Li2ZnO2(aq) + 2 H2O ( l)

The only compound that will form a precipitate with LiOH would be ZnBr2

Precipitation reactions

These are double displacement reactions in which precipitates are produced. Precipitates are insoluble solids formed from the combination of ions in aqueous solutions.

In this case, a reaction between LiOH and ZnBr2 would be as follows;

2LiOH + ZnBr2 ----------> 2LiBr + Zn(OH)2 (s)

Zn(OH)2 is an insoluble salt and will precipitate out in the solution.

Explanation:

Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.

How to tell if a reaction is exothermic.

Answers

Answer:

If the reaction loses heat it is exothermic.

If the enthalpy change listed for a reaction is negative, then that reaction releases heat as it proceeds — the reaction is exothermic (exo- = out). If the enthalpy change listed for the reaction is positive, then that reaction absorbs heat as it proceeds — the reaction is endothermic (endo- = in).

What makes a hydrocarbon saturated?

Answers

Answer:

Explanation:

It's easier to answer what makes it unsaturated.

H - C ≡ C - H

This is Acetylene. It has three shared bonds between the two carbons. That many bonds makes it unsaturated.

     H   H

H - C - C - H

     H   H

Draw lines from 1 H on top to the Carbon underneath Do the same with the other hydrogen. Make the two Hydrogens on the bottom do the same thing.

The point is that Carbon has 4 bonds. 1 bond goes to the other Carbon. The other 3 take on Hydrogen. That molecule is saturated: nothing can be added in its natural state.

Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. ... They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen.

What is the frequency of yellow light, which has a wavelength of 5.56 x 10^-7 m?
O A) 5.40 x 10^14 m/s
O B) 5.40 x 10^14 Hz
O C) 1.85 x 10^15 m/s
O D) 1.85 x 10^15 Hz

Answers

The answer is B 5.40 x 10^14 Hz

The frequency of yellow light, which has a wavelength of 5.56 x 10^-7 m is  5.40 x 10^14 Hz. Therefore, option B is correct.

What do you mean by wavelength ?

The distance between identical points (adjacent crests) in adjacent cycles of a waveform signal propagated in space or along a wire is defined as the wavelength. This length is typically specified in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).

The wavelength is the distance between two wave crests, and it is also the distance between two wave troughs. The frequency is measured in cycles per second (Hz) and is the number of vibrations that pass over a given spot in one second (Hertz).

Speed is distance over time, Therefore, v = λ / T.

The frequency, f, is 1/T, so the equation relating wave speed, frequency, and wavelength is v = c / λ .

Given :

Wavelength = 5.56 x 10^-7 m

Frequency = ?

Speed (c) = 3 × 10⁸m/s

v = c / λ

By substituting given values in equation and we get,

v =  3 × 10⁸ / 5.56 x 10^-7

= 5.40 x 10^14

The frequency of yellow light is 5.40 x 10^14.

Thus, option B is correct.

how many grams of magnesium cyanide would you need to add to 275 ml of water to make a 0.075 molal solution

Answers

The mass of magnesium cyanide needed to prepare the solution is 1.57 g

We'll begin by calculating the number of mole of Mg(CN)₂. This can be obtained as follow:

Volume = 275 mL = 275 / 1000 = 0.275 L

Molarity of Mg(CN)₂ = 0.075 M

Mole of Mg(CN)₂ =?

Mole = Molarity x Volume

Mole of Mg(CN)₂ = 0.075 × 0.275

Mole of Mg(CN)₂ = 0.020625 mole

Finally, we shall determine the mass of Mg(CN)₂

Mole of Mg(CN)₂ = 0.020625 mole

Molar mass of Mg(CN)₂ = 24 + 2(12 + 14) = 76 g/mol

Mass of Mg(CN)₂ =?

Mass = mole × molar mass

Mass of Mg(CN)₂ = 0.020625 × 76

Mass of Mg(CN)₂ = 1.57 g

Therefore, 1.57 g of Mg(CN)₂ is needed to prepare the solution

Pressure Cooking

Explanation:

Pressure cooking is a very old cooking method that’s experienced a recent resurgence thanks to a new generation of cookers that promise a speedy, set-it-and-forget-it path to dinner. These devices, whether electrical or stovetop, are all much safer than those of decades ago (which tended to explode), with mechanisms to prevent them from accumulating too much pressure. If you read the owner’s manual carefully, however, you’ll still find one important precaution to take when cooking under pressure: adding water. Water and pressure cooking go hand in hand. In fact, it’s water that helps generate the high-pressure environment that makes your food cook faster.

Most pressure cooker instructions state a minimum amount of water required for pressure cooking even a tiny amount of food. Inside the tightly sealed pressure cooker, the water is heated and eventually boils into steam. Since the steam cannot escape, it collects above the food. All those trapped water molecules increase the pressure inside the cooker.
