Na reação de óxido de alumínio com ácido sulfúrico forma-se sulfato de alumínio (equação abaixo). Levando em consideração que a

reação tenha um rendimento total, para produzir 6 mols desse sulfato, qual é a quantidade de matéria, em mol, de ácido necessária?

Answer:

18 moles de ácido

Explanation:

A reação de óxido de alumínio com ácido sulfúrico é:

Al₂O₃ + 3H₂SO₄ → Al₂(SO₄)₃ + 3H₂O

<em>Onde 1 mol de óxido de alumínio reaciona com 3 moles de ácido sulfúrico produzendo 1 mol de sulfato de alumínio e 3 moles de água.</em>

Agora, se você quizer produzir 6 moles de sulfato de alumínio, e você sabe que 3 moles de ácido formam 1 mol de sulfato, as moles de ácido que você precisa são:

6 moles Al₂(SO₄)₃ × ( 3 moles H₂SO₄ / 1mole Al₂(SO₄)₃) = <em>18 moles de ácido</em>

<span>Answer: .01 moles of D to .005 moles of L ~ so, .01+.005 = .015 total; using this total value, divide the portions of D and L. so .01/.015 to .005/.015 ~ 67% D to 33% L. And thus, the enantiomer excess will be 34%.</span>

What is the concept of Dimensional Analysis?
7nadin3 [17]

Answer:

In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometers, or pounds vs. kilograms) and tracking these dimensions as

What is the volume (in cm^ 3 ) of 1.2 moles of water vapor at RTP? Calculate the mass of this water vapor.
mars1129 [50]

Answer:

Volume = 29400 cm³

Mass =  21.6 g

Explanation:

Given data:

Number of moles of water vapors = 1.2 mol

Mass of water vapor = ?

Volume of water vapors = ?

Solution:

Room temperature = 25 °C (25+273 = 298 K)

Room pressure = 1 atm

PV = nRT

V =  nRT/P

V = 1.2 mol × 0.0821 atm. K⁻¹. mol⁻¹ . L × 298 K/ 1 atm

V = 29.4 L

In cm³:

29.4 × 1000 = 29400 mL

mL = cm³

Mass of water vapors:

<em>Mass = number of moles × molar mass</em>

Mass = 1.2 mol × 18 g/mol

Mass =  21.6 g

Which of these Group 14 elements has the most metallic properties? 1. C 2. Ge 3. Si 4. Sn
seraphim [82]
I would say that the answer is Sn.
C-is a non-metal
Ge-is a metalliod (consists both non-metal and metal)
Si -is a metalloid
Sn- is a pure metal
