The moon would stop orbiting us and instead it’s kinetic energy would keep it going in one direction indefinitely until it collides with another entity. There is a specific name for this phenomena but I cannot recall it.

solution is 2.41 molal toluene (C 7H 8, 92 g/mol) in benzene (C 6H 6, 78 g/mol); i.e. consider toluene the solute, benzene the s
inn [45]

Answer : The molarity of solution is, 1.73 mole/L

Explanation :

The relation between the molarity, molality and the density of the solution is,

where,

d=M[\frac{1}{m}+\frac{M_b}{1000}]

d = density of solution  = 0.876g/cm^3=0.876g/mL

m = molality of solution  = 2.41 mol/kg

M = molarity of solution  = ?

M_b = molar mass of solute (toluene) = 92 g/mole

Now put all the given values in the above formula, we get  the molality of the solution.

0.876g/ml=M\times [\frac{1}{2.41mol/kg}+\frac{92g/mole}{1000}]

M=1.73mol/L

Therefore, the molarity of solution is, 1.73 mole/L

How many grams hydrogen in 4.5 mol H2SO4
swat32
H2SO4 ---> 2H^+ + SO4^2-

Hence n H+ = 9 mols

Mass of H = nM = (9*1) = 9g


Alternately

mass of H2SO4= nM= 4.5*98= 441

Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g

A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder
IRISSAK [1]

Answer:

A. Up

B. Out

C. Out

D. To equilibrum

Explanation:

a. The reaction in an exothermic reaction so this means heat is given off. If the cylinder is thin enough heat will transfer to the water bath

b. Since the products will create heat which will increase pressure, the piston in an attempt to maintaining a constant pressure will move up to accommodate building pressure.

c. Heat will flow out of the gaseous mixture as this reaction creates heat as a product as well

d. Heat will flow out in the capacity to create an equilibrium with the water bath that it is in.

Indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium after changing th
Viktor [21]

Explanation:

Since this is an equilibrium problem, we apply le chatelier principle. This principle states that whenever a system at equilibrium is disturbed due to change in several factors, it would move in a way to annul such change.

C2H4(g) + Cl2 ⇔ 2C2H4Cl2(g)

When the concentration of C2H4 is increased, there is more reactant sin the system. In order to annul this change, the equilibrium position will shift to the right favoring product formation.

When the concentration of C2H4Cl2 is increased, there is more product in the system. To annul this change, the equilibrium position will shift to the left, favoring reactant formation.
