Answer:
= 0.238 L
Explanation:
From the given information:
To convert cm³ to L(liter), we utilize the advent of a unit fraction that comprises a liter in the upper part of the fraction(numerator) and a cubic centimeter in the lower part of the fraction(denominator)
Recall that:
1000 cm³ = 1 liter
∴
238.0 cm³ = 
= 0.238 L
The intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
Answer: Solids
Explanation:
In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
The standard cell potential is obtained from the equation of the reaction.
<h3>What is the standard cell potential?</h3>
The standard cell potential is obtained from the equation of the reaction. Now we have the overall cell equation as from the half reactions as;
Oxidation half reaction;
Al(s) --->Al³+ (aq) + 3 e
Reduction half equation;
Cu²+ (aq) + 2 e →→ Cu(s)
Standard cell potential Eºcell = 0.34V - (-1.66 V) = 2 V
Now;
ΔG = -nFEcell
ΔG = -(2 * 6 * 96500 * 2)
ΔG = -2316kJ
E = 2 - 0.0592/6 log [0.0025]/[3.5 M]
E = 2 + 0.031
E = 2.031 V

Answer:
Explanation:
Given data:
Mass of water used = 4.05 g
Mass of each product produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 4.05 g/ 18 g/mol
Number of moles = 0.225 mol
Now we will compare the moles of water with hydrogen and oxygen.
H₂O : H₂
2 : 2
0.225 : 0.225
H₂O : O₂
2 : 1
0.225 : 1/2×0.225 = 0.113 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.225 × 2 g/mol
Mass = 0.45 g
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.113 mol × 32 g/mol
Mass = 3.616 g
