How much heat is released when heat is condensed to form 100g of water

Chemistry
1 answer:
lakkis [162]2 years ago
4 0

Answer:

2260 J of heat must be absorbed by the water. Conversely, when 1 g of steam at 100 ºC condenses to give 1 g of water at 100 ºC, 2260 J of heat will be released to the surroundings.

Explanation:

I believe this is correct. :')

How would you prepare 2.5 L of a 0.800M solution of KNO3?
statuscvo [17]
First  find the mass of <span>solute:

Molar mass KNO</span>₃ = <span>101.1032 g/mol

mass =  Molarity * molar mass * volume

mass = 0.800 * 101.1032 * 2.5

mass = 202.2064 g of KNO</span>₃

<span>To prepare 2.5 L (0800 M) of KNO3 solution, must weigh 202.2064 g of salt, dissolve in a Beker, transfer with the help of a funnel of transfer to a volumetric flask, complete with water up to the mark, capping the balloon and finally shake the solution to mix.</span>

hope this helps!

Why do cells use fat and starch for long term energy storage instead of ATP molescules?
IceJOKER [234]
ADP is like an uncharged battery. ATP is like a charged battery, ready to provide energy to do work in the cell. The charging of ADP into ATP takes place in the mitochondria. Fat and starch are stable (last a long time) whereas ATP goes dead too quick and will need to be recharged.

glucose is a carbon chain molecule (sugar). When the bonds in the chain are broken, energy is released. That energy is used to turn ADP into ATP. Glucose is the "electricity" used to charge the battery.

Mn2+

The molarity of the stock Mn²⁺ ions is 0.0288 M

Based on the dilution formula;

  • The molarity of A is 0.00144 M
  • The molarity of B is 0.0000576 M
  • The molarity of C is 0.000001152 M

<h3>What is the molarity of a solution?</h3>

The molarity of a solution is the number of moles of a solute dissolved in a given volume of solution in liters.

  • Molarity = number of moles/volume

The molarity of the stock solution is:

moles of Mn²⁺ ions = mass / molar mass

molar mass of  Mn²⁺ ions = 55.0 g/mol

moles of Mn²⁺ ions = 1.584 / 55

moles of Mn²⁺ ions = 0.0288 moles

molarity of Mn²⁺ ions = 0.0288 / 1

molarity of Mn²⁺ ions = 0.0288 M

The dilution formula is used to determine the molarities of A, B, and C.

C₁V₁ = C₂V₂

C₂ = C₁V₁ / V₂

Where;

  • C₁ = initial molarity
  • V₁ = initial volume
  • C₂ = final molarity
  • V₂ = final volume

Molarity of A = 50 * 0.0288 / 1000

Molarity of A = 0.00144 M

Molarity of B = 10 * 0.00144 / 250

Molarity of B = 0.0000576 M

Molarity of C = 10 * 0.0000576 / 500

Molarity of C = 0.000001152 M
