Zinc sulfide and oxygen gas react to form zinc oxide and sulfur dioxide. Determine the amount (g) of SO2 that should be produced in a reaction between 32.5 g of ZnS and 23.3 g of oxygen gas. What is the mass of the xs reactant?
Answer:
7.30g O₂ are in excess and 21.3g of SO₂ should be produced.
Explanation:
The reaction of Zinc sulfide (ZnS) with oxygen (O₂) produce ZnO and SO₂ as follows:
2ZnS + 3O₂ → 2ZnO + 2SO₂
Using this reaction we can find the amount of SO₂ produced converting the ZnS and O₂ to moles and finding limiting and excess reactant as follows:
Moles ZnS -Molar mass: 97.47g/mol-:
32.5g * (1mol / 97.47g) = 0.333 moles ZnS
Moles O₂ -Molar mass: 32g/mol-:
23.3g O₂ * (1mol / 32g) = 0.728 moles O₂
For a complete reaction of the 0.333 moles of ZnS are required:
0.333 moles ZnS * (3mol O₂ / 2mol ZnS) = 0.500 moles O₂.
As there are 0.728 moles of O₂, limiting reactant is ZnS and excess reactant is O₂.
The moles and mass of O₂ in excess are:
0.728mol - 0.500mol = 0.228moles O₂ * (32g / mol) = 7.30g O₂ are in excess
The produced mass of SO₂ -Obtained from the moles of ZnS- is:
0.333 moles of ZnS * (2mol SO₂ / 2mol ZnS) = 0.333 moles SO₂
0.333 moles SO₂ * (64.066g / mol) =
21.3g of SO₂ should be producedHow can you increase reaction rate in the forward direction? Chose all that

______ is a way to describe matter with numbers and units.
Measurement is a way to describe matter with numbers and units.
Measurement is a fundamental process used to describe and quantify various aspects of matter. It involves assigning numerical values to physical quantities and expressing them using appropriate units of measurement.
In scientific and everyday contexts, measurements provide a standardized and consistent way to communicate information about the properties, dimensions, quantities, and characteristics of objects, substances, or phenomena. By using measurements, we can describe the size, length, mass, volume, temperature, time, and many other attributes of matter.
The process of measurement typically involves two components: a numerical value and a unit. The numerical value represents the magnitude or quantity being measured, while the unit provides the reference or scale by which that quantity is expressed. Units help provide meaning, context, and comparability to measurements.
Hence, measurement provides a quantitative and objective way to describe matter, allowing us to understand and interact with the physical world in a systematic and meaningful manner.

Describe what happens inside a CD
player when you listen to an audio CD.
The thing that happens inside a CD player when you listen to an audio CD is that laser beam turns on and scans along a track with the photocell from the CD's center.
What are semiconductors?The electrical conductivity of a semiconductor material is between that of a conductor, such as metallic copper, and that of an insulator, such as glass.
A small photoelectric cell and a smaller laser beam (called a semiconductor diode laser) are found inside your CD player (an electronic light detector). When you hit play, the disc is rotated at a high speed by an electric motor (not visible in this figure) (up to 500rpm).
The laser beam turns on and scans along a track with the photocell from the CD's center to its edge (in the opposite way to an LP record). As the laser/photocell scans from the center to the periphery of the disc, the motor gradually slows it down (as the track number increases, in other words).
Hence laser beam turns on and scans along a track with the photocell from the CD's center.

Which type of data relies on the senses or things you can't measure
Answer:
Nominal data
Explanation:
This is a type of data in which its set of values don't have a nominal arrangement.
For example, the color of a football jersey can be deemed as a nominal data type as we can’t distinguish one color from others. Like It is impossible to declare that ‘Pink' is greater than ‘Yellow'.
how does the law of conservation of mass applies to all chemical reactions?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Explanation:
The law of conservation is Matter cannot be created or destroyed in chemical reactions so it means exactly that
