Answer:
Forces like wind and water break down rocks through the processes of weathering and erosion. ... Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface.
Explanation:
Answer:
134K
Explanation:
Using the ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (Litres)
n = number of moles (mol)
R = gas constant (0.0821 Latm/Kmol)
T = temperature (K)
Based on the information provided, n = 1.4moles, P = 3.25atm, V = 4.738L, T = ?
3.25 × 4.738 = 1.4 × 0.0821 × T
15.3985 = 0.11494T
T = 15.3985/0.11494
T = 133.969
Approximately;
T = 134K
Answer: The formic acid is 3.5 times stronger than acetic acid.
Explanation:
The strength of an acid depends on its acid dissociation constant.
For a hypothetical monoprotic acid HA, the dissociation equilibrium is:
More is the value of , greater is the dissociation and stronger is the acid.
Thus formic acid is 3.5 times stronger than acetic acid.
Answer:
H₂ + O₂ → H₂O
Now, check that oxygen has two atoms on the left and one on the right
so, you put 2 on the right side
H₂ + O₂ → 2H₂O
oxygen is balanced so, add 2 on H₂ to balance out hydrogen
THE FINAL BALANCED EQUATION:
<h2>
2H₂ + O₂ → 2H₂O</h2>
The law of conservation of mass states that:
"For any closed system, mass is preserved. This means that the total amount of mass remains constant as mass can neither be created nor destroyed".
Applying this to the decomposition we have,
since the total mass of reactants (water) is 10 grams, therefore, the total mass of products (hydrogen and oxygen) is also 10 grams
