One mole of aluminum contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, 0.55 moles of aluminum contains 3.31 × 10²³ atoms.
What is Avogadro number ?One mole of any substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. One mole of every elements contains Avogadro number of atoms.
Aluminum is 13th element in periodic table. It shows metallic properties as well as some non-metallic properties. The symbol of aluminum is Al. It forms compounds mostly through covalent bonding.
One mole of aluminum contains 6.022 × 10²³ atoms.
Thus, number of atoms in 0.55 moles = 0.55 × 6.022 × 10²³ = 3.31 × 10²³ atoms.
Therefore, the number of Al atoms in 0.55 moles is 3.31 × 10²³ .

Explanation:
substances decrease in size on __ (heating/ cooling) and contract.
Answers
It is for this reason that many substances become more dense as temperature decreases. For example, cold air (which is technically a mixture, but it works for our purposes) is denser than warm air, and cold water is denser than warm water. Density is defined as the amount of mass per volume. If the temperature is reduced, the amount of mass isn’t changed. So the increase in density must be due to the change in volume; for density to go up, the volume must go down. One can consider this in isolation: a balloon placed in a freezer will shrivel up as the “size” of the gas inside the balloon decreases.
There are, of course, exceptions, the most famous perhaps being water. While water, like most liquids, does decrease in size on cooling, it only does so up to a point (specifically 4 degrees C); after this point, water expands (its volume increases and density decreases) as it is cooled further, which holds even after it freezes; that is why solid water (ice) floats in liquid water—which isn’t the case with many other substances whose solids states are denser than their liquid states.

Which of the following best describes an Arrhenius acid-base reaction?
O A. Acid + base = H+ + OH-
B. Acid + base = salt + water
C. Acid + base = conjugate base + conjugate acid
D. Acid + base =
H20
Answers
Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.

How do I balance coefficient equations
Answers
Answer:
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
Answer: When you balance a chemical equation, you change coefficients. You never change subscripts. A coefficient is a whole number multiplier. To balance a chemical equation, you add these whole number multipliers (coefficients) to make sure that there are the same number of atoms on each side of the arrow.

Calculate ΔG for this reaction at 12.7
°C.
Answers
Answer:
[tex]\Delta G=-675.38 \frac{kJ}{mol}[/tex]
Explanation:
Hello!
In this case, for this problem, it is possible to use the thermodynamic definition of the Gibbs free energy:
[tex]\Delta G=\Delta H-T\Delta S[/tex]
Whereas G, H and S can be assumed as constant over T; thus, we can calculate H at 135.4 °C:
[tex]\Delta H=\Delta G+T\Delta S\\\\\Delta H=-775.41\frac{kJ}{mol}+(135.4+273.15)K*(0.81791\frac{kJ}{mol*K} )\\\\\Delta H=-441.58\frac{kJ}{mol}[/tex]
Now, we can calculate the Gibbs free energy at 12.7 °C as shown below:
[tex]\Delta G=-441.58\frac{kJ}{mol} -(12.7+273.15)K*0.81791\frac{kJ}{mol*K}\\\\\Delta G=-675.38 \frac{kJ}{mol}[/tex]

1. The percent ionization in the potassium formate solution is____than that in pure water because of the____.
2. The equilibrium for the dissociation of formic acid is shifted to the____by this addition, and a____amount of acid dissociates.
Answers
Answer:
1. The percent ionization in the potassium formate solution is smaller than that in pure water because of the common ion effect.
2. The equilibrium for the dissociation of formic acid is shifted to the left by this addition, and a smaller amount of acid dissociates.
Explanation:
The common ion effect refers to the effect on equilibrium that is observed when an ion that is already contained in the solution (common ion) is added to a solution. The addition of a common generally results in a shift in equilibrium positiont towards the removal of the common ion from solution. This is according to Le Châtelier's Principle which states that if an equilibrium becomes unbalanced, the reaction will shift to restore the balance.
The common ion effect decreases the ionization of a weak acid as the addition of more of an ion that is a product of this equilibrium will shift equilibrium towards removal of the ion.
Adding a common ion also decreases solubility, as the reaction shifts toward the left in order to annul the constraint of the excess ion in the product side of equilibrium.
The percent ionization in the potassium formate solution is smaller than that in pure water because of the Common ion effect. The equilibrium for the dissociation of formic acid is shifted to the left by this addition, and a smaller amount of acid dissociates.
What is Equilibrium law?Equilibrium law states that if any external effect is applied on the equilibrium state of any chemical reaction, then the equilibrium will shift towards that side where the effect will decrease.
Common ion effect occurs when the already present ion in the solution is further added to the solution which increases the concentration of that ion in the solution and equilibrium will shift towards the side where common ion effect will decreases.
That's why the percentage of ionization in the potassium formate solution is less than the percentage of ionization in pure water. And due to common ion effect equilibrium will shift towards the left side where dissociation decreases and the concentration of ions is also decreases.
Hence correct options are smaller, common ion effect, left and smaller.
