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.

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.

Answer:

The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.

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.

The IUPAC name for NH3 is Ammonia  

The IUPAC name is also known as (International Union of Pure and Applied Chemistry) and it is a standardized system by chemical scientists for naming chemical compounds.

The IUPAC name for NH3 is Ammonia. Ammonia is a colorless gas with a stifling odor that is an exceedingly unpleasant pungent smell. It dissociates quickly in water to generate ammonium hydroxide, which can irritate and burn the skin.

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

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.

Behavior

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 = Molarity x Volume

Mole of Mg(CN)₂ = 0.075 × 0.275

Mole of Mg(CN)₂ = 0.020625 mole

Mole of Mg(CN)₂ = 0.020625 mole

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

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

Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase "I think, therefore I am".

Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to Rene Descartes. This Latin phrase is roughly translated as "I think, therefore I am", which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

Answer:

The speed of the wave decreases.

Explanation:

When light waves do pass through a medium, any solid, liquid, or gas, the speed of the waves actually decreases. Solids are more dense than liquids, so they decrease the speed of light even more.

Explanation:

So copper is a lattice of positive copper ions with free electrons moving between them. 

The number of moles of XeF4 that can be created would be 0.5 moles.

From the equation of the reactiobn:

                Xe (g) 2 F₂ (g) ---> XeF₄ (g)

The mole ratio of Xe to F2 is 1:2. Hence, in the presence of 1 mole Xe and 1 mole F2, F2 would be limiting the reaction.

This means that the amount of F2 would determine the amount of XeF4 that would be produced from the reaction.

The mole ratio of F2 to XeF4 according to the equation is 2:1. This means that for every 1 mole of F2 introduced into the reaction, 0.5 moles of XeF4 will be produced.

In this case, 1 mole of F2 is introduced. Thus, the mole of XeF4 that would be produced would be:

                       1/2 = 0.5 moles.
