tiny-mole [99]2 years ago
5 0

Answer:

In thermodynamics, the Joule–Thomson effect describes the temperature change of a real gas or liquid when it is forced through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment. This procedure is called a throttling process or Joule–Thomson process

Individual solute particles are broken apart from the solid by these particles. * a Solution b Insoluble c Solvent d Compounds
Maru [420]

Answer:

Individual solute particles are broken apart from the solid by the;

c. Solvent

Explanation:

A solution is the homogeneous mixture that is made up of two or more substances formed by dissolving a substance which can be a solid, liquid or gas in another substance known as the solvent which normally the larger part of the fraction of the solution than the solute and can also be a solid, liquid or a gas

In a solution the solvent particles serves to brake of and disperser parts of a solid solute to form a more or less homogeneous mixture

Therefore, the solute particles are broken by the <u>solvent</u> particles in a solution

Why does it generally take more enthalpy to ignite a solid than a gas or liquid?
Anuta_ua [19.1K]

Answer:

It is due to the nature of the reactants

Explanation:

To ignite a solid, we require more heat component compared to liquids and gases. For ignition to occur, oxygen gas combines with a reactant in most cases.

Some factors affect the rate rate at which a chemical proceeds. One of the factors is the nature of reactants.

The solid phase is very slow while the gaseous phase is rapid and fast.

            solid phase < liquid phase <  gas phase

Gases are free and the molecules move in all direction. They easily combine and react very fast.

Write this number in standard notation.<br> 1.986 x 10negative exponent 6 or 1.986 x 10^6
Brums [2.3K]

Answer:

0.000001986

Explanation:

We have the number 1.986*10^{-6}. Standard notation would basically be this number without the 10^{-6} part.

To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).

So, when we move the decimal point 6 places to the left, the resulting number is: 0.000001986, with 5 zeros after the decimal point before a nonzero number.

Thus, the answer is 0.000001986.
