The milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.
What is neutralization?Neutralization is defined as a chemical reaction in which an acid and a base quantitatively react with one another. Because it determines how acidic or basic a solution is, a solution's pH is crucial. The interaction of H+ ions and OH- ions produces water in a neutralization reaction, which occurs when an acid and a base react to form water and a salt.
Since the mole ratio of HClO4 to NaOH is 1:1, the moles of HClO4 are equal to 4.16 x 10-3 moles.
The moles of NaOH are equal to (0.0832 x 50) /1000.
Therefore, the volume of HClO4 is equal to the moles/molarity, which is 4.16 x 10-3mol/ 0.167 mol/L= 0.0249L.
This amount is then multiplied by 1000 to get ml: 0.0249 x 1000 = 24.9 ml.
Thus, the milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.

What volume of oxygen at 455 K and a pressure of 127400 Pa is produced by the decomposition of 114.7 g of BaO2 to BaO and O2?
Answer:
10 L
Explanation:
The equation of the reaction is;
2BaO2 = 2BaO + O2
Number of moles of BaO2 = 114.7 g/169.33 g/mol = 0.677 moles
From the reaction equation;
2 moles of BaO2 yields 1 moles of O2
0.677 moles of BaO2 yields 0.677 * 1/2 = 0.3385 moles of oxygen
Hence;
PV=nRT
V = ?
P = 127400 Pa or 1.257 atm
T = 455 K
n = 0.3385 moles
R = 0.082 atmLmol-1K-1
V = nRT/P
V = 0.3385 * 0.082 * 455/1.257
V= 10 L

Answer:
Poop
Explanation:
Answer:
convergergent
Explanation:
Mountains form where two continental plates collide. Since both plates have a similar thickness and weight, neither one will sink under the other. Instead, they crumple and fold until the rocks are forced up to form a mountain range. As the plates continue to collide, mountains will get taller and taller.

25.2 g of CuSO4 6H20 (mm: 267.72 g/mol) is dissolved in 28.0 mL of water, calculate the molarity.
Answer:
3.36 M
Explanation:
Step 1: Given data
Mass of CuSO₄.6H₂O (m): 25.2 gMolar mass of CuSO₄.6H₂O (M): 267.72 g/molVolume of solution (V): 28.0 mL (we will assume it is equal to the volume of water)Step 2: Calculate the moles (n) of CuSO₄.6H₂O (solute)
We will use the following expression.
n = m/M
n = 25.2 g / (267.72 g/mol) = 0.0941 mol
Step 3: Calculate the molarity
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.0941 mol/0.0280 L = 3.36 M

Explanation:
A sample of methane gas, CH4, occupies 3.25 L at temperature of 19.0 o C. If the pressure is held constant, what will be the temperature be if the volume expands to 10.00 L?
Answer:
625.46 °C
Explanation:
We'll begin by converting 19 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
T(°C) = 19 °C
T(K) = 19 °C + 273
T(K) = 292 K
Next, we shall determine the Final temperature. This can be obtained as follow:
Initial volume (V₁) = 3.25 L
Initial temperature (T₁) = 292 K
Final volume (V₂) = 10 L
Final temperature (T₂) =?
V₁/T₁ = V₂/T₂
3.25 / 292 = 10 / T₂
Cross multiply
3.25 × T₂ = 292 × 10
3.25 × T₂ = 2920
Divide both side by 3.25
T₂ = 2920 / 3.25
T₂ = 898.46 K
Finally, we shall convert 898.46 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 898.46 K
T(°C) = 898.46 – 273
T(°C) = 625.46 °C
Therefore the final temperature of the gas is 625.46 °C
Please Help :))) "A solution with a concentration of 5.7 x 10^-7M would be considered..."
Answer:
The solution is acidic.
Explanation:
To know which option is correct, we shall determine the pH of the solution. This can be obtained as follow:
Concentration of Hydrogen ion [H⁺] = 5.7×10¯⁷ M
pH =?
pH = –Log [H⁺]
pH = –Log 5.7×10¯⁷
pH = 6.2
pH scale reads as follow:
0 to 6.9 => Acidic
7 => Neutral
8 to 14 => Alkaline / basic
The pH of the solution (i.e 6.2) falls between 0 and 6.9 which indicates acidic.
Therefore, the solution is acidic.

Help ASAP I’ll mark you as brainlister
Answer:
94.9% yield
Explanation:
Percent yield = actual yield/theoretical yield x 100
So you will divide the actual yield (what they really produced) over the theoretical yield (what they expected to produce). This will give you a decimal answer, which you multiply by 100 to get a percent.
169g/178g = 0.949 x 100 = 94.9%

Explanation:
A heterogeneous mixture is a mixture where the components are not uniform in composition, like oil and water. They don't mix. When you mix oil and vinegar, you have 2 layers because oil is less dense than vinegar.
A 40.0L tank of ammonia has a pressure of 12.7kPa. Calculate the volume of the ammonia if its pressure is changed to 8.4 kPa while its temperature remains constant
Answer:
60.5 L
Explanation:
If the gas temperature is constant, we can use Boyle's law:
P1V1 = P2V2
V2 = P1V1 / P2
P1 = 12.7 kPa
V1 = 40.0 L
P2 = 8.4 kPa
V2 = (12.7 kPa) (40.0 L) / (8.4 kPa) = 60.5 L
