Does ch3cn dissolve in water?
Acetonitrile is easily ignited by heat, sparks or flames and gives off highly toxic hydrogen cyanide fumes when heated. It dissolves easily in water. It can react with water, steam or acids to produce flammable vapors that can form explosive mixtures when exposed to air.
What happens when potassium nitrate is dissolved in water?
Dissolving potassium nitrate in water is an endothermic process because the hydration of the ions when the crystal dissolves does not provide as much energy as is needed to break up the lattice. Forming an ionic lattice from gaseous ions like this is always an exothermic process since bonds are being formed.
What is the product of potassium nitrate and water?
It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre in the UK)….Potassium nitrate.

Which substance is most soluble in water?
d. Water, too, is considered to be a polar molecule and, as we know, likes dissolve likes. Hence, C2H5OH C 2 H 5 O H will be the most soluble in water.
What happens when something dissolves in water?
As each solute molecule gradually breaks away, water molecules surround it, and it drifts into solution. If the solute is a solid, this process happens gradually. The surface molecules are the first to go, exposing the ones underneath to water molecules that have not yet bonded.
What are the keys to predicting the products of the five general types of reactions?
The five general types of reaction are combination, decomposition, single-replacement, double-replacement, and combustion. How can you predict the products of the five general types of reactions? The number of elements and/or compounds reacting is a good indicator of possible reaction type and thus possible products.
How do you know what products are formed in a chemical reaction?
To predict the products of such a reaction, see what happens if the chemical breaks into smaller, familiar products such as water, carbon dioxide, or any of the gaseous elements. When pure elements are combined, synthesis reactions are the frequent result.
Is ch3 2co soluble in water?
Acetone is a manufactured chemical that is also found naturally in the environment. It is a colorless liquid with a distinct smell and taste. It evaporates easily, is flammable, and dissolves in water. It is also called dimethyl ketone, 2-propanone, and beta-ketopropane.
Is LiCl soluble in water?
Lithium chloride is certainly the least water-soluble of the three compounds. That makes sense, since the lithium ions are small and the attraction for the chloride would be stronger over that shorter distance….Exercise 3.4. 3.

How much products are formed in a reaction?
The amount of product generated by a chemical reaction is its actual yield. This yield is often less than the amount of product predicted by the stoichiometry of the balanced chemical equation representing the reaction (its theoretical yield).
What do you call to a substance that enters into a chemical reaction?
The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
Is toluene soluble in water?
Toluene has a molecular weight of 92.14 g mol−1. At 25 °C, toluene has a solubility in water of 526 mg l−1, an estimated vapor pressure of 28.4 mm Hg and a Henry's Law Constant of 6.64 × 10−3 atm-m3 mol−1(USEPA, 2011).

Is mgco3 soluble in water?
Medical use. It is a laxative to loosen the bowels. In addition, high purity magnesium carbonate is used as an antacid and as an additive in table salt to keep it free flowing. Magnesium carbonate can do this because it does not dissolve in water, only in acid, where it will effervesce (bubble).

When cacl2 dissolves in water which is true?
1 Expert Answer. Since CaCl2(s) is a strong electrolyte, it dissolves completely in water, so it will form Ca2+ ions and Cl- ions. However, you must know that every mole of CaCl2(s) will form 1 mole of Ca2+ ions and 2 moles of Cl- ions (as indicated by the subscripts), so your chemical equation should look like…
