Answer:
290 g of hydrogen peroxide would fill the 200.0 mL container
Explanation:
Given data:
Volume = 200.0 mL
Mass of hydrogen peroxide = ?
Solution:
Density of hydrogen peroxide is 1.45 g/cm³.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Now we can determine the mass of hydrogen peroxide.
D = m/v
1.45 g/cm³ = m/ 200.0 mL
1 mL = 1 cm³
m = 1.45 g/cm³× 200.0 cm³
m = 290 g
So 290 g of hydrogen peroxide would fill the 200.0 mL container.
2. High tempertaure and low pressure
3. HCL,NH3,H20
4. higher collisions ieThe greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
Explanation:
Expansion:
1. Suppose gas particles are moving in a linear fashion but if they collide with some thing they will fil that. This explains expansion theory of gases.
Fluidity: The gas molecules are in dependent of each other and have low density, they are in constant motion hence have fluidity.
low density: The gas molecules are far apart as compared to solid and liquid hence have low density.
compressibility: Due to the large distance between the gas molecules they collide with each other and vessel wall and when the space is constricted they start moving faster. They are elastic in nature.
Diffusion: Yes, because when gas is mixed it starts moving in the mixture randomly.
2. The molecules in real gas are at large distance. The high temperature and low pressure real gas would behave ideally. Because increase temperature would cause higher movement of gas particles.
3. HCL, NH3 and H2O are polar gases they will have relatively different attractive forces between them.
4. The greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
5. The gas particles get closer, enough pressure not provided. It increases the kinetic energy as heat is produced due to compaction of molecules. The particles would not move and will become liquid causing volume to increase.
6. The gas molecules start moving rapidly, move farther apart .Volume and pressure also increases.
Answer: The reaction does occur.
Explanation: For the reaction of aqueous strontium sulfide and aqueous copper(II) sulfate, the reaction follows:
This reaction is a type of precipitation reaction.
The precipitate formed is CuS which is black in color.
Answer:
The answer is
<h2>0.89 atm </h2>
Explanation:
To convert from kPa to atm we use the conversion
101.325 kPa = 1 atm
If
101.325 kPa = 1 atm
Then
90.23 kPa will be
We have the final answer as
<h3>0.89 atm</h3>
Hope this helps you
Answer:
pH will always be less than 7
Explanation:
This is because NH3 is a relatively weak base and the resulting Acidic salt on titration might hydrolyse to form a buffer solution
