Note that this is occurring at STP, where 22.4L of any gas is equal to 1mol of that gas.
First, convert the liters of O₂ to moles of O₂ using the conversion factor 22.4LO₂ = 1molO₂.
8.6LO₂ × 1molO₂/22.4LO₂
= 8.6/22.4
≈ 0.3839molO₂
Next, convert moles of O₂ to moles of H₂O. In the balanced equation, the coefficients show that there are 2 moles of H₂O for every mole of O₂. So, use the conversion factor 1molO₂ = 2molH₂O.
0.3839molO₂ × 2molH₂O/1molO₂
= 0.3839 × 2
= 0.7678molH₂O
Finally, convert the moles of H₂O to liters of H₂O using the same conversion factor from before, 22.4LH₂O = 1molH₂O.
0.7678molH₂O × 22.4LH₂O/1molH₂O
= 0.7678 × 22.4
≈ 17LH₂O
So, the answer is 17 liters of gaseous water is collected! Note that its rounded to 17 because the measurement given in the problem has 2 sig figs. Hope that helps! :)
The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7
<h3>What is
pOH scale?</h3>
Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.
The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.
The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.

Answer:
The answer to your question is below
Explanation:
There are 4 types of chemical reactions:
- Synthesis is when two elements or compounds form only one compound.
- Decomposition is when 1 compound is broken into 2 or more products.
- Single replacement is when one element is replaced by another element.
- Double replacement is when the cations of two compounds are interchanged.
6.- Synthesis Al + 3Cl ⇒ AlCl₃
7.- Double replacement 2NaOH + H₂SO₄ ⇒ Na₂SO₄ + 2H₂O
8.- Decomposition Ni(ClO₃)₂ ⇒ NiCl₂ + 3O₂
9.- Combustion 2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
10.- Single replacement Zn + 2HCl ⇒ ZnCl₂ + H₂
Answer:
the sustainability of economic growth
Explanation:
Equation 1
weight of 2 bolt = 6.75 weight of washer
Equation 2
mass = W/g
Where
g = 9.8m/s^2
mass of box of 2 bolt = weight of 2 bolt x 2 bolt pcs/box/9.8 m/s^2
mass of box of 2 bolt = 6.75 weightwasher x 2 bolt pcs/box
if there are 144 pcs of bolts/box
mass of box of 2 bolt= 6.75 weight of washer x 144/9.8m/s^2
mass of box of 2 bolt = 972 weight of washer /9.8m/s^2
=99.18 weight of washer s^2/m
