the percent error for the density of the liquid in each graduated cylinder is -1.38% in A and 1.39% in B
To calculate the percent error for the density of the liquid in each graduated cylinder, we need to use the following formula:Error percent is calculated as [(experimental value - acceptable value) / accepted value]. x 100. First, we'll calculate the density of the liquid in graduated cylinder A: Density of liquid A = mass of liquid A / volume of liquid A = (23.54 - 17.83) g / 5 mL = 3.56 g/mLNow we'll calculate the percent error for density of liquid A: % Error = [(3.56 g/mL - 3.61 g/mL) / 3.61 g/mL] x 100 = -1.38%. Next, we'll calculate the density of liquid B: Density of liquid B = mass of liquid B / volume of liquid B = (23.9 - 18.07) g / 5 mL = 3.61 g/mL. Now we'll calculate the percent error for density of liquid B:% Error = [(3.61 g/mL - 3.56 g/mL) / 3.56 g/mL] x 100 = 1.39%. It's worth noting that the percent error for the density of liquid A and B are opposite in sign and similar in magnitude, this implies that the measurement errors in mass and volume are likely to be canceled out when measuring the density, resulting in relatively low error.

how many grams of aluminum bromide are formed from the reaction of aluminum and hydrogen bromide if you have excess al and 121 g of hbr
The reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.
The chemical equation for the reaction between aluminum and hydrogen bromide is:
[tex]2 Al + 3 HBr[/tex] →[tex]Al_2Br_6[/tex]
From this equation, we can see that the reaction is a stoichiometric reaction, which means that the ratio of the reactants and products is fixed and is determined by the coefficients in the balanced equation.
If we have 121 grams of hydrogen bromide, the number of moles of hydrogen bromide can be calculated using the molar mass of hydrogen bromide ([tex]HBr[/tex]) which is approximately 80.9 g/mol. So:
121 g [tex]HBr[/tex] / 80.9 g/mol = 1.49 mol [tex]HBr[/tex]
Since the coefficient of hydrogen bromide in the balanced equation is 3, we know that for every one mole of aluminum, we need 3 moles of HBr. So, in this case, we have excess [tex]Al[/tex], which means the limiting reactant is [tex]HBr[/tex], and we have 1.49 moles of [tex]HBr[/tex].
The number of moles of aluminum bromide ([tex]Al_2Br_6[/tex]) formed can be calculated by dividing the number of moles of [tex]HBr[/tex] by the coefficient of [tex]HBr[/tex] in the balanced equation, which is 3
1.49 moles [tex]HBr[/tex] / 3 = 0.497 moles [tex]Al_2Br_6[/tex]
We can calculate the number of grams of aluminum bromide by multiplying the number of moles by the molar mass of aluminum bromide, which is approximately 427.3 g/mol
0.497 moles [tex]Al_2Br_6[/tex] * 427.3 g/mol = 212.44 g [tex]Al_2Br_6[/tex]
So, the reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

The [OH-] Of A 0.180 min F- Solution. Ka For HF Is 6.8 X 10-4. E.
[OH^-] = 0.004 Moles
To determine the [OH-] of a solution, we can use the relationship between the acid dissociation constant (Ka) and the base dissociation constant (Kb).
The relationship is: Kb x Ka = Kw
Where Kw is the ion product constant of water which is 1.0 x 10^-14 at 25°C.
We know that the Ka of HF is 6.8 x 10^-4. To find the Kb of F-, we'll use the above terms.
Kb x 6.8 x 10^-4 = 1.0 x 10^-14
Kb = 1.0 x 10^-14 / 6.8 x 10^-4
Kb = 1.47 x 10^-11
To find the [OH-] of the solution, we'll use theformulae:
[OH-] = sqrt(Kb)
[OH-] = sqrt(1.47 x 10^-11)
[OH-] = 0.0038
So the [OH-] of the solution is 0.0038 M

28.35 x 0.15825 = 4.49 grams
In other words, 0.750 tsp of baking soda would be worth 4.49 grams of baking soda going by the available conversion factors.

Write balanced net ionic equation for the following reaction: Fe(OH)3(s) + H2SO4(aq)→? Express your answer as a chemical equation
The balanced net ionic equation is:
2Fe⁺³(aq) + 6OH⁻(s) + 6H⁺(aq) + 3SO₄⁻² (aq) → Fe₂(SO₄)₃(s) + 6H₂O(l).
How is the ionic equation discovered?All soluble ionic compounds (those denoted with a (aq)) must be broken down into their corresponding ions in order to write the ionic equation. Each ion needs to be displayed with its charge and a (aq) to signify that it is in solution. Coefficients can be used to display the quantity of each ion.
The net ionic equation is the chemical formula that only displays the substances that are directly involved in the reaction. The spectator ions are also included in a complete ionic equation, whereas a net ionic equation only displays the chemical species that are involved in a reaction.

point(s) where only a gas is present b) temperature at which vaporization occurs c) point(s) where a mixture of a solid and a liquid are present d) point(s) where a gas turns into a liquid e) temperature at which the substance starts to freeze f) range where there is only a liquid
The solution for the above questions are gas phase, boiling point, the solid-liquid (melting point) phase, condensation point, freezing point and liquid phase respectively.
What is vaporization?Vaporization is the process by which a substance is transformed from its liquid or solid state into its gaseous (vapor) state. Boiling is the term for the vaporization process when conditions permit the formation of vapor bubbles within a liquid. Sublimation is the process of directly converting a solid into a vapor.
a) point(s) where only a gas is present: the gas phase
b) temperature at which vaporization occurs: the boiling point
c) point(s) where a mixture of a solid and a liquid are present: the solid-liquid phase boundary
d) point(s) where a gas turns into a liquid: the condensation point
e) temperature at which the substance starts to freeze: the freezing point
f) range where there is only a liquid: the liquid phase
