Answer:

Salts can be several different colors and may be any of the five tastes, including salty, sweet, bitter, sour or savory. Their odor depends on the acid and base it is comprised of. Salts comprised of strong acids and bases, called strong salts, are odorless.

Consider the reaction for the combustion of butane (C4H10), a component of liquefied petroleum (LP) gas. 2C4H10(g)+13O2(g)→8CO2(

polet [3.4K]

Answer:

The answer to your question is:

a) 3.87 mol of CO2

b) 14.63 mol of O2

Explanation:

2C4H10(g) + 13O2(g) → 8CO2(g) + 10H2O(g)

CO2 = ?

Butane 0.968 moles

From the balance equation 2 moles of butane ---------- 8 moles of CO2

0.968 moles of butane ------ x

x = (0.968 x 8) / 2

x = 3.87 moles of CO2

moles O2 = ?

butane = 2.25 mol

From the balance equation

2 moles of butane ---------- 13 mol O2

2.25 mol ---------- x

x = (2.25 x 13) / 2

x = 14.63 mol of O2

For the following reaction, Kc = 15 at 700 K. 2 NO(g) + Cl2(g) ⇄ 2 NOCl(g) If we have [NO] = 0.15 M, [Cl2] = 0.15 M, [NOCl] = 0.

vovangra [49]

Answer : The correct option is, The equilibrium will shift to the left until all the NOCl is used up.

Explanation :

Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given balanced chemical reaction is,

$2NO(g)+Cl_2(g)\rightarrow 2NOCl(g)$

The expression for reaction quotient will be :

$Q=\frac{[NOCl]^2}{[NO]^2[Cl_2]}$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

Now put all the given values in this expression, we get

$Q=\frac{(0.40)^2}{(0.15)^2(0.15)}=47.4$

The given equilibrium constant value is, $K=15$

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

There are 3 conditions:

When $Q>K$ that means product > reactant. So, the reaction is reactant favored.

When $Q$ that means reactant > product. So, the reaction is product favored.

When $Q=K$ that means product = reactant. So, the reaction is in equilibrium.

From the above we conclude that, the $Q>K$ that means product > reactant. So, the reaction is reactant favored that means reaction must shift to the reactants to be in equilibrium or shift to the left side.

Hence, the correct option is, The equilibrium will shift to the left until all the NOCl is used up.

What is a covalent bond

diamong [38]

Answer:

Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).

I believe it was Hiroshima. Followed by Nagasaki. Moscow was never bombed in my knowledge, and Auschwitz was a death camp, so it wasn't bombed.
