How many atoms are in KOH?

Chemistry
1 answer:
Nata [24]3 years ago
3 0

Answer:

KOH contains only one K, so a mole of KOH contains one mole of K. How many atoms of K are in 1 mole of KOH? There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K.

Carbon dioxide, when it is at -145 degreesC has a density of 2.54 g/L. What is the pressure in torr??
Black_prince [1.1K]

Answer: The pressure in torr is 461 torr

Explanation:

To calculate the relation of density and molar mass of a compound, we use the ideal gas equation:

PV=nRT

P = pressure

V = Volume

n = number of moles

R = gas constant = 0.0821 Latm/Kmol

T = temperature =-145^0C=(273-145)K=128K

Number of moles (n) can be written as:

n=\frac{m}{M}

where, m = given mass

M = molar mass  = 44 g/mol

PV=\frac{m}{M}RT\\\\PM=\frac{m}{V}RT

where,

\frac{m}{V}=d

where d = density = 2.54 g/L

The relation becomes:

PM=dRT  

P=\frac{dRT}{M}

P=\frac{2.54\times 0.0821\times 128}{44}=0.607atm

P=461torr    (760torr=1atm)

Thus the pressure in torr is 461 torr

Which statement is true of energy in reactants during an endothermic reaction? (1 point)
pychu [463]

All of the energy from the reactants will be lost to the surroundings.The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.

<h3>What is Endothermic reaction?</h3>

Endothermic reaction is a reaction in thermochemistry where the reactants absorb heat from the surrounding to form the products.

In an endothermic reaction, the products have more energy than the reactants, that is they absorbed more energy. The reactants have less energy,that is they loss energy . Therefore, the change in enthalpy is positive, heat is absorbed from the surroundings during the reaction.

Therefore, All of the energy from the reactants will be lost to the surroundings.

The energy found in the reactants remains in the system, and the reactants also take energy from the

surroundings is true of energy in reactants during endothermic reaction.
