assuming you find the peroxide to be 1m, how many grams of h2o2 is in the 1 ml of hydrogen peroxide solution?
Answers
The peroxide to be 1 M, grams of H₂O₂ is in the 1 mL of hydrogen peroxide solution is 0.034 g.
Given that :
molarity of hydrogen peroxide , H₂O₂ = 1 M
volume of hydrogen peroxide . H₂O₂ = 1 mL = 0.001 L
The molarity expression is given as:
Molarity = number of moles / volumes in L
number of moles of H₂O₂ = molarity × volume
= 1 × 0.001
= 0.001 mol
now, the number of moles is given as :
number of moles = mass / molar mass
mass of H₂O₂ = number of moles × molar mass
= 0.001 × 34
= 0.034 g
Thus, The peroxide to be 1 M, grams of H₂O₂ is in the 1 mL of hydrogen peroxide solution is 0.034 g.

PLEASE HELP!! Will give 1st answer Bainliest. Explain the electrical conductivity of melted and of aqueous solutions of ionic compounds using the characteristics of ionic compounds.
Answers
Answer:
When ionic compounds are melted, the orderly crystal structure breaks down and each ion can move freely. When ionic compounds dissolve, their ions dissociate from each other and move freely. When voltage is applied, cations migrate to one electrode and anions migrate to the other which equals the flow of electricity.
Explanation:
assuming all the salts below are the same concentration, which salt would lower the freezing point of water the most?
Answers
The salt that would lower the freezing point of water the most is sodium chloride.
Sodium chloride is the most effective salt at decreasing the freezing point of water. This is because sodium chloride has the highest solubility of all the salts, meaning that it can dissolve and form a solution with a higher concentration of solute. This leads to a decrease in the freezing point of water, as the solute molecules interfere with the structure of the water molecules and prevent them from forming an orderly pattern. Other salts, like potassium chloride, magnesium sulfate, and calcium chloride, may still lower the freezing point of water, but to a lesser degree compared to sodium chloride.

Calcium chloride is the salt which lower the freezing point of water the most.
The freezing point can be defined as the is the exact temperature at which a liquid becomes a solid. The freezing point of water is 32 degrees Fahrenheit. Freezing point describes the moment of transition much as the melting point captures the moment when ice turns from a solid to a liquid. Normal fresh water freezes at 32 degrees Fahrenheit and seawater freezes at about 28.4 degrees Fahrenheit because of the salt in it. Calcium chloride is highly soluble in water. It lowers the freezing point of water the most. Both calcium chloride and magnesium chloride have lower the freezing points. When calcium chloride comes in contact with ice, it rapidly lowers the freezing point of water and melts snow and ice quickly. Calcium chloride forms brine faster than other salts because of its hygroscopic properties.

The initial concentration of sodium oxalate, Na₂C₂O4 is 1.34 M. After 19.3 seconds its concentration is
0.276 M
(Triangle)Na₂C₂O4 =
Rate =
Answers
The rate of change of the concentration of Na₂C₂O4 is -0.0551 M/s.
To determine the rate of change of the concentration of sodium oxalate (Na₂C₂O4), we can use the rate equation:
Rate = (Δ[Na₂C₂O4]) / (Δt)
where Δ[Na₂C₂O4] represents the change in concentration of Na₂C₂O4 and Δt represents the change in time.
In this case, the initial concentration of Na₂C₂O4 is 1.34 M, and after 19.3 seconds, the concentration is 0.276 M.
Substituting the values into the rate equation, we have:
Rate = (0.276 M - 1.34 M) / (19.3 s - 0 s)
Rate = (-1.064 M) / (19.3 s)
Rate = -0.0551 M/s
Therefore, the rate of change of the concentration of Na₂C₂O4 is -0.0551 M/s.
The negative sign indicates that the concentration of Na₂C₂O4 is decreasing over time, as the reactant is being consumed in the reaction.
It's important to note that the rate of a reaction is influenced by various factors, such as the reaction mechanism, temperature, and presence of catalysts. The rate can be determined experimentally by measuring the change in concentration of a reactant or product over a specific time interval.
The given information allows us to calculate the rate of change for the specific reaction involving Na₂C₂O4. However, without additional information about the reaction, it is not possible to determine the exact nature or stoichiometry of the reaction, as well as any other reactants or products involved.

Yes, igneous rock become sedimentary rock through a process called sedimentation.
The sedimentary rock formed in the process above arises from sediment that was compacted and cemented. When igneous rock is lifted up by plate motion toward Rhombus’s surface, it become exposed to energy from Rhombus’s sun. Therefore, wind and water can move and breakdown the igneous rock into sediment. This process here, the sedimentary rock could have been igneous rock.In sedimentation, An igneous rock is broken down or crushed into little piece of rock called sediment, the sediment is then packed together as a result of othe rocks or strong forces, that form together to make a Sedimentary rock.

group ia reactivity was demonstrated on a video you were expected to view. match the following observations of group ia chemical reactivity with the metal which demonstrates it.
Answers
Group IA metals, also known as alkali metals, include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These metals demonstrate high reactivity due to their single electron in the outermost energy level. This makes them eager to lose that electron, resulting in a positive ion.
As you go down Group IA, the chemical reactivity of the metals increases. This is because the outermost electron is further from the nucleus and experiences less attraction to the protons, making it easier to remove.
To match the observations of Group IA chemical reactivity with the metals, follow this trend:
1. Lithium (Li) - Lowest reactivity in Group IA.
2. Sodium (Na) - Moderate reactivity, more than lithium but less than potassium.
3. Potassium (K) - Higher reactivity, more than sodium but less than rubidium.
4. Rubidium (Rb) - High reactivity, more than potassium but less than cesium.
5. Cesium (Cs) - Very high reactivity, more than rubidium but less than francium.
6. Francium (Fr) - Highest reactivity in Group IA, but due to its rarity and instability, it is not commonly observed.

The correct reaction for the enthalpy of formation of ozone at 25 °C is D. 3O2(g) → 2O3(g).
The reaction D represents the formation of ozone (O3) from molecular oxygen (O2) gas. This reaction involves three molecules of O2 combining to form two molecules of O3. The enthalpy of formation is defined as the change in enthalpy when one mole of a substance is formed from its constituent elements in their standard states. In this case, the standard state of oxygen is O2(g), and the standard state of ozone is O3(g).
The reaction D correctly shows the stoichiometry of the formation of ozone, where three molecules of O2 react to produce two molecules of O3. This balanced equation represents the enthalpy change associated with the formation of ozone and is consistent with experimental observations and thermodynamic data.

after ten years, 75 grams remain of a sample that was
originally 100 grams of some unknown radio isotope. find the half
life for this radio isotope
Answers
The half-life of the radioisotope, calculated based on the given information that after ten years only 75 grams remain from an initial 100 grams, is approximately 28.97 years.
To find the half-life of the radioisotope, we can use the formula for exponential decay:
N(t) = N₀ × (1/2)^(t / T₁/₂)
T₁/₂ is the half-life of the substance.
In this case, we know that the initial amount N₀ is 100 grams, and after ten years (t = 10), 75 grams remain (N(t) = 75 grams).
We can plug these values into the equation and solve for T₁/₂:
75 = 100 × (1/2)^(10 / T₁/₂)
Dividing both sides of the equation by 100:
0.75 = (1/2)^(10 / T₁/₂)
Taking the logarithm (base 2) of both sides to isolate the exponent:
log₂(0.75) = (10 / T₁/₂) × log₂(1/2)
Using the property log₂(a^b) = b × log₂(a):
log₂(0.75) = -10 / T₁/₂
Rearranging the equation:
T₁/₂ = -10 / log₂(0.75)
Using a calculator to evaluate the logarithm and perform the division:
T₁/₂ ≈ 29.13 years
Therefore, the half-life of the radioisotope is approximately 28.97 years.
