if 19.1 mL of 1.26 M HBr is headed to 23.7g of CAC03 what volume of CO2 would be produced as 713.6 torr and 29.9°C
Answers
Answer:
0.32 L
Explanation:
The equation of the reaction is;
2HBr(aq) + CaCO3(s) ----->CaBr2(aq) + H2O(l) + CO2(g)
The number of moles HBr reacted = 19.1/1000 L * 1.26 M = 0.024 moles
According to the reaction equation;
2 moles of HBr produces 1 mole of CO2
0.024 moles of HBr produces 0.024 * 1/2 = 0.012 moles of CO2
For CaCO3
Number of moles = 23.7g/100 g/mol = 0.237 moles
Since the reaction is 1:1, 0.237 moles of CO2 is produced.
Hence HBr is the limiting reactant and 0.012 moles of CO2 is produced.
From PV =nRT
V = nRT/P
P= 713.6 torr
n= 0.012 moles
T = 29.9°C + 273 = 302.9 K
R = 62.36 L torr/mol K
V = 0.012 * 62.36 * 302.9/713.6
V = 0.32 L

*2Al+3CuSO4=Al2(SO4)3+3Cu: single replacement.
*C2H5OH+3O2=2CO2+3H2O: combustion.
Explanation:
Hello there!
In this case, according to the required, it turns out necessary for us to recall the five types of reactions, combination, decomposition, single and double replacement and combustion as shown on the attached figure.
In such a way, since the first reaction follows the pattern AB+CD-->AD+CB we infer it is double replacement; the second reaction follows the patter A+BC-->AC+B and therefore it is single replacement; and the last one follows the pattern of combustion reaction due to the presence of CO2 and H2O on the products side.

The carbon-oxygen double bond, or carbonyl, is a key feature of many organic molecules. Two resonance structures can be used to illustrate the properties of the carbonyl structure as provided. In analyzing the minor resonance structure, what can we conclude about the Lewis acid properties of the carbonyl
Answers
The question is incomplete, the complete question is shown in the image attached to this answer
Answer:
B
Explanation:
A Lewis acid is specie that has vacant orbitals and is able to accept a lone pair of electrons while a Lewis base is any specie having a lone pair of electrons which can be donated to another chemical specie.
Hence a Lewis acid accepts a lone pair of electrons while a Lewis base donates a lone pair of electrons.
From the resonance structure shown, the carbon atom in the carbonyl compound ought to function as the Lewis acid since it is electrophilic (electron deficient).
Answer: The Carbon atom in the carbonyl will act as a lewis acid and will accept a pair of electrons
Explanation:
In the minor resonance structure for the carbonyl group, we observe a positive formal charge on the carbon atom. Because of its positive formal charge, the carbon atom will act as a Lewis acid and accept a pair of electrons to stabilize that formal charge.

Printed circuit boards are used in the electronics industry to both connect and hold components in place. In production, 0.03 in. of copper foil is laminated to an insulating plastic board. A circuit pattern made of a chemically resistant polymer is then printed on the board. Next, the unwanted copper is chemically etched away by using selected reagents. If copper is treated with Cu(NH3 ) 4Cl2 (cupric ammonium chloride) and NH4OH (ammonium hydroxide), the products are water and Cu(NH3) 4Cl (cuprous ammonium chloride). Once the copper is dissolved, the polymer is removed by solvents, leaving the printed circuit ready for further processing. If a single-sided board 4 in. by 8 in. is to have 75% of the copper layer removed using these reagents, how many grams of each reagent will be consumed? Data: The density of copper is 8.96 g/cm3.

4 moles of ammonia react to 5 moles of oxygen in order to produce 6 moles of water and 4 moles of NO
We need to determine the limiting reactant:
Ratio is 4:5, As 4 moles of ammonia react to 5 moles of oxygen and we have 4 moles, we definetely need 5 moles, but the problem is, we only have 2.5 moles of O₂. Oxygen is the limting reagent.
5 moles of O₂ produce 4 moles of NO, according to stoichiometry
2.5 moles of O₂ may produce (2.5 . 4) / 5 = 2 moles of NO

Consider a hypothetical metal that has a density of 3.55 g/cm3, an atomic weight of 40.48 g/mol, and an atomic radius of 0.135 nm. Compute the atomic packing factor if the unit cell has tetragonal symmetry, values for the a and c lattice parameters are 0.545 and 0.255, respectively.
Answers
Answer:
0.5447
Explanation:
The atomic packing fraction factor is given by
APF = Volume of sphere/ Volume of unit cell
[tex]APF = \frac{N\times V_N}{V_C}[/tex]
The atomic radius = 0.135 nm
The Density of the metal = 3.55 g/cm^3
To calculate the number of atoms
= desnsity/(atomic radius×Avagadro's number)
Putting values and solving we get
the number of atoms = 4
Now,
[tex]APF = \frac{4\times 4/3\pi(0.135\times10^{-9})^3}{(0.545\times10^{-9})^2(0.255\times10^{-9})}[/tex]
Solving we get
APF = 0.54427

Calculate the percent composition by mass (to 4 significant figures) of all the elements in calcium phosphate [Ca3(PO4)2], a major component of bone.
Answers
Answer:
The elements present in calcium phosphate-based on molecular formula are calcium, phosphorus, and oxygen. The molecular mass of Ca or calcium is 40.08 grams per mole, the molecular mass of P or phosphorus is 30.97 grams per mole, and the molecular mass of oxygen is 16.00 grams per mole. So, in combination, the molecular mass of Ca₃(PO₄)₂ is, = (3 × 40.08 + 2 ×3 0.97 + 8 × 16) = 310.18 grams per mole
Now, the mass percent of calcium is, = n × molecular mass of calcium/ molecular mass of Ca₃(PO₄)₂ × 100% = 3 × 40.08 / 310.18 × 100 = 38.76 % Thus, the mass percent of the calcium in calcium phosphate is 38.76%.
The mass percent of phosphorus (P), = n × molecular mass of phosphorus/molar mass of Ca₃(PO₄)₂ × 100% = 2 × 30.97/310.18 × 100 = 19.97% Thus, the mass percent of phosphorus in calcium phosphate is 19.97%.
The mass percent of oxygen (O), = n × molecular mass of oxygen/molar mass of Ca₃(PO₄)₂ × 100% = 8 × 16/310.18 × 100% = 41.27% Thus, the mass percent of oxygen in calcium phosphate is 41.27%.

Explanation:
In an experiment, a student was assigned to find the formula of an unknown hydrate that weighed 15.67g. The anhydrate, XCO3 (molar mass = 84.32 g/mol), weighed 7.58 g after all the water was driven off. Determine the moles of water per one mole of anhydrate.
Answers
Answer:
5.0 moles of water per one mole of anhydrate
Explanation:
To solve this question we must find the moles of the anhydrate. The difference in mass between the dry and the anhydrate gives the mass of water. Thus, we can find the moles of water and the moles of water per mole of anhydrate:
Moles Anhydrate:
7.58g * (1mol / 84.32g) = 0.0899 moles XCO3
Moles water:
15.67g - 7.58g = 8.09g * (1mol / 18.01g) = 0.449 moles H2O
Moles of water per mole of anhydrate:
0.449 moles H2O / 0.0899 moles XCO3 =
5.0 moles of water per one mole of anhydrate
