Answer: Stationary front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or “standing still.”

Intermolecular forces and kinetic energy both play a role in the phase a substance is in at a particular temperature and pressur

Step2247 [10]

Answer:

(Highest kinetic energy)

3. Neon at 65 K and 15 atm

2. Neon at 55 K and 10 atm

4. Neon at 25 K and 5 atm

1. Neon at 5 K and 0 atm

(Lowest kinetic energy)

Explanation:

In gases, kinetic energy is higher the higher the temperature is. This is because the molecules have more available energy under those conditions. Generally there's also an increase in kinetic energy if there's an increase in pressure -assuming there's no phase changes ie. the gas condenses into a liquid-.

Write the equilibrium constant expression for the following reaction in terms of concentrations of the components. (Concentratio

timofeeve [1]

Answer: The expression for equilibrium constant in terms of concentration is $K_c=[CO_2]$

Explanation:

Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by $K_{c}$

For a general chemical reaction:

$aA+bB\rightarrow cC+dD$

The $K_{c}$ is written as:

$K_{c}=\frac{[C]^c[D]^d}{[A]^a[B]^b}$

The concentration of pure solids and pure liquids are taken as 1.

For the given chemical reaction:

$MgCO_3(s)\rightarrow MgO(s)+CO_2(g)$

The expression for $K_{c}$ is:

$K_{c}=\frac{[MgO][CO_2]}{[MgCO_3]}$

In the above expression, magnesium oxide and magnesium carbonate will not appear because they are present in solid state.

So, the expression for $K_c$ becomes:

$K_{c}=[CO_2]$

Hence, the equilibrium constant for the reaction is given above.

What is the most important question to ask to determine wheatear a change is physical or chemical

spin [16.1K]

The most important thing to determine whether a change is physical or chemical is whether the substance was changed. When the substance being changed, it is chemical change. Otherwise, it is physical.
