The required moles of water and anhydrous salt in the given reaction is 0.06 moles.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

From the given data, mass of left water will be calculated by substracting the mass of CuSO₄ from the anhydrous salt as:

  • Mass of Left water =  1.6 - 0.5 = 1.1 g
  • Moles of left water = 1.1g / 18g/mol = 0.06 moles

Chemical reaction will be represented as:

CuSO₄.XH₂O → CuSO₄ + XH₂O

From the stoichiometry of the reaction it is clear that 0.06 moles of water is produced from 0.06 moles of anhydrous compound.

Ratio of the moles of water to salt = 0.06 / 0.06 = 1

So name of the compound CuSO₄.H₂O is copper sulfate monohydrate.

Hence, 0.06 moles of water as well as anhydrous compound is involved in the reaction and name of the obtained compound is copper sulfate monohydrate.

Describe the interactions of the nervous and the muscular system
STatiana [176]
<h2>The nervous  and the muscular system interacts as follows</h2>
  • Receptors in the muscles [provide the brain with information about the body position  and movement.
  • The brain send signal  back  down the spinal  cord directed to the location of desired muscle
  •  The ultimate effect of this signals is the acetylcholine  is  released onto  the muscle  fibers  which target nicotinic cholinergic receptors  which open ion channel that cause the  muscle to contract.

A single atom of hydrogen has a mass of 1.0 amu, while a mole of hydrogen atoms has a mass of 1.0 g. Select the correct conversi
user100 [1]

Answer:

1g = 6.022 x 1023 AMU

Explanation:

An atomic mass unit or AMU is a physical constant which is equal to one-twelfth of the mass of an unbound  carbon-12 atom.

One unified atomic mass unit is equal to 1.66 yoctograms = 1.66053904020 x 10-24 g.

1 AMU is equivalent to 1.66 x 10-24 grams and 1 gram is equivalent to 6.022 x 1023 AMU.

Thus,1g = 6.022 x 1023 AMU.
