Serhud [2]2 years ago

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

<h3>What is molarity?</h3>

Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of moles of solute per liter of solution.

We want to find the moles of iron (II) nitrite (solute) in 125 mL of a 3.5 M solution. We will use the definition of molarity.

M = n / V(L)

n = M × V(L) = 3.5 mol/L × 0.125 L = 0.438 mol

where,

  • M is the molarity.
  • n is the number of moles.
  • V(L) is the volume of the solution in liters.

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

How do a steam engine do work a steam enter a cylinder and pushes a piston be steam causes wills to turn C steam turns a turbine
lapo4ka [179]

Answer:

In a steam engine into a reciprocating piston cylinder assembly a high pressure steam is been admitted.

Explanation:

Steam engine: High-pressure steam is been injected into a piston-cylinder assembly which is reciprocating in nature. some part of its thermal energy gets converted into movement of the piston to work,When the steam starts expanding to lower pressure.

 Apparatus which is separate and a condenser at comparatively low temperature and pressure here steam is passed.The expanded steam can then be made to be free, or, for engine efficiency to be maximum, Rotary motion with a crank-crankshaft assembly similar to that used in automobiles gets transferred from that.

Remaining heat has been now used for warming water.

 boiler fired with coal, oil, or natural gas by them the steam gets supplied.

. In many areas, more reliable and economical diesel-electric locomotives gets supplanted by the steam locomotives.  

The steam engines today generally are regarded as a unique piece as they are not considered as above reasons are explained.

Nevertheless, the creation of the steam engine played a vital role in the Revolution carried out by the industries by creating a society which now is less dependent on the different windmills, the watermills and mostly the animal power.

L and D forms of a molecule are what kind of isomers?
kotegsom [21]

Answer:

enantiomers

Explanation:

L and D stand for levorotatory and dextrorotatory respectively. A levorotatory molecule will rotate the plane of plane polarised light left and a dextrorotatory molecule will rotate the plane of plane polarised light right.  L and D molecules are non superimposable mirror image of each other. Therefore they are also known as enantiomers.
