What is the molarity of a solution with 2 moles of HCl in 2000 mL?
ikadub [295]

Answer:

"1 M" will be the right solution.

Explanation:

The given values are:

Number of moles,

= 2 moles

Volume of solution,

= 2000 mL

or,

= 2 L

Now,

The molarity of the solution will be:

=  \frac{Moles}{Liters}

On substituting the values, we get

=  \frac{2}{2}

=  1 \ M

Which of the statements accurately describes compounds?
kow [346]

Answer:

True statements are 2, 4, 5

Explanation:

They can be broken down by chemical means because we need to break chemical bonds between two (or more) atoms.

They are pure substance because one can't separate them by physical means.

When one separate compounds on two (or more) substances, there are two (or more) different species and they all act differently.

Several interesting observations from the world around you are listed below. Which of these is NOT explained by a colligative pr
Phantasy [73]

Answer:

1.) At high altitude it takes longer to cook spaghetti.

Explanation:

The first even describes depression in boiling point due to reduction in external pressure . It is not a colligative property.

Depression of freezing  point and elevation of boiling point due to impurity or addition of solute are colligative priperty.

Consider the following redox equation Mn(OH)2(s) + MnO4 –(aq)  MnO42 –(aq) (basic solution) When the equation is balanced with
inysia [295]

Answer : The balanced chemical equation is,

2MnO_4^-(aq)+Mn(OH)_2(s)+4OH^-(aq)\rightarrow 3MnO_4^{2-}(aq)+2H_2O(l)

The coefficient for OH^- is, 4 and on reactant side of the equation OH^-(aq) is present.

Explanation :

Rules for the balanced chemical equation in basic solution are :

  • First we have to write into the two half-reactions.
  • Now balance the main atoms in the reaction.
  • Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
  • If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
  • If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion (OH^-) at that side where the less number of hydrogen are present.
  • Now balance the charge.

The half reactions in the basic solution are :

Reduction : Mn(OH)_2(s)+1e^-\rightarrow MnO_4^{2-}(aq) ......(1)

Oxidation : MnO_4^-(aq)+4OH^-(aq)\rightarrow MnO_4^{2-}(aq)+2H_2O(l)+2e^-.....(2)

Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.

The balanced chemical equation in a basic solution will be,

2MnO_4^-(aq)+Mn(OH)_2(s)+4OH^-(aq)\rightarrow 3MnO_4^{2-}(aq)+2H_2O(l)

Thus, the coefficient for OH^- is, 4 and on reactant side of the equation OH^-(aq) is present.

At what temperature will 55 grams of chlorine gas Cl2 exert a pressure of 245 kPa at a volume of 3.4 liters?
DiKsa [7]

132.67 K is the temperature at which 55 grams of chlorine gas exert a pressure of 245 kPa at a volume of 3.4 liter.

Explanation:

Data given:

mass of chlorine gas  = 55 grams

atomic mass of chlorine gas = 71 grams/mole

pressure of chlorine gas = 245 kPa 0R 2.41 atm

volume of the chlorine gas = 3.4 litres

temperature of the chlorine gas = ?

R = 0.08201 Latm/moles K

n =?

Assuming that chlorine behaved like ideal gas, the formula used will be,

PV = nRT

number of moles = \frac{mass}{atomic mass of 1 mole}

number of moles= \frac{55}{71}

number of moles = 0.77

putting the values in ideal gas equation:

T = \frac{2.41 X 3.4}{0.08021 X 0.77}

T = 132.67 K

temperature is 132.67 K
