Crystals of different soluble solids are not similar because they are amorphous and therefore do not have definite crystals.
What are crystal solids?A crystalline solid is a homogeneous solid in which the constituent particles, atoms, ions or molecules are arranged in a definite repeating pattern.
Most of the solid substances are crystalline in nature. The arrangement of particles in a crystalline solid is such that the total intermolecular force of attraction is at maximum.
Factors in which solubility depends are temperature, pH, and ionic strength.
Crystals of different soluble solids are not similar as they do not have definite crystals.

What products would you expect from the reaction of ammonia and sulfuric acid in aqueous solution
Answer:
(NH4)2SO4
Explanation:
2NH3(aq) + H2SO4 (aq) ---> (NH4)2SO4(aq)
Ammonia reacts with sulfuric acid to give the fertilizer ammonium sulfate.
NaC2H3O2 HOH --> HC2H3O2 NaOH Since the two products are a weak acid and a strong base, we expect this mixture to be basic. When NaF reacts with water in the same manner, the products would be NaOH and _______.
The products of the reaction would be NaOH and HF
From the question,
We are to determine the products of the reaction between NaF and water in the same manner as the given reaction.
To determine the other product, we will write the equation for the reaction
The equation for the reaction is
NaF + H₂O → NaOH + HF
Hence, the products of the reaction would be NaOH and HF.

2AlCl3 --> 2Al + 3Al2
If you produce 15 moles of Al, how many grams of AlCl3 decomposed?
Answer:
1597,5 gm AlCl3 decomposed
Explanation:
2AlCl3 --> 2Al + 3Al2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed?
FIRST, you need to write down the the correct reaction. Your equation makes no sense
here is the correct question
2AlCl3 --> 2Al + 3Cl2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed?
for every mole of Al produced, we decomposed a mole of AlCl3
so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3
15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed
6.02 times 10 to the 23 atoms of an element have a mass in grams equivalent to the mass of how many of the atoms in amu?
Answer:
Relation between AMU and Gram
The mass of an atom in amu is numerically the same as the mass of one mole of atoms of the element in grams. One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g. For compounds, the molecular mass (in amu) is numerically the same as the mass of one mole of the compound in grams.

Convert 4.0 moles of krypton into liters of krypton.
Answer:
4.0 moles of krypton converts to 89.6L.
Explanation:
To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.
We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

Have a nice day
Imagine yourself making a nice cup of tea on a cold winter day. You begin by boiling some water in a kettle. Next, you add the steaming liquid to your cup. Then, you open a tea bag and repeatedly dunk it into the water. You pour a dash of milk and drop a few sugar cubes into the cup, stirring the solution with a spoon. Finally, you squeeze a bit of lemon into your tea mixture. However, before you have time to stir the lemon juice into your tea, the liquid forms clumps. In other words, your tea has curdled!
Based on the scenario, answer the questions below.
Which of the four indicators of a chemical change is described in the paragraph above?
What makes the tea with milk and lemon curdle?
Name some of the chemical substances in the tea mixture. (You will need to conduct some research on your own to do this.)

The relative atomic mass of chlorine is 35.5.
When calculating relative atomic mass, which particle is the mass of a chlorine atom compared
to?
Given what we know, we can confirm that relative atomic mass is calculated by comparing the particles to the atomic mass of a carbon-12 atom.
Why compare to carbon-12?Carbon is a very common element. It was been studied greatly, telling us a great deal about the atom. It contains 6 protons and 6 neutrons.This makes it very stable and the standard for comparison.Therefore, given its abundant nature and the fact that it has been extensively studied, we can confirm that a carbon 12 atom has exactly 6 protons and 6 neutrons, making it very stable and the standard to which other atoms are compared.
