Answer:
22.4 L at standard temperature and pressure.
Answer:
Explanation:
There are three types of interactions involved between the particles when solution are formed.
1 : Solute - solute interaction:
2 : Solute - solvent interaction:
3 : Solvent - solvent interaction:
1 : Solute - solute interaction:
It is the inter-molecular attraction between the solute particles.
2 : Solute - solvent interaction:
It involve the inter-molecular attraction between solvent and solute particles.
3 : Solvent - solvent interaction:
It involve the intermolecular attraction between solvent particles.
Solutions are formed if the intermolecular attraction between solute particles are similar to the attraction between solvent particles.
Exothermic process:
The process will exothermic when solute solvent bonds are formed with the release of energy and energy required to brake the solute-solute particles and solvent solvent particles are less.
Endothermic process:
The process will be endothermic when energy required to break the solute-solute particles and solvent solvent particles are higher than energy released when solute solvent bonds are formed .
Carbon Dioxide + Water --> Glucose + Oxygen + Energy(ATP)
Also photosynthesis only takes place in plant cells due to the fact that they are autotrophs and make their own food.
Reactants: Carbon Dioxide + Water
Products: Glucose, Oxygen, and Energy
Answer:
1.70
Explanation:
The molar mass of perchloric acid is 100.46 g/mol. The moles corresponding to 484 mg (0.484 g) are:
0.484 g × (1 mol/100.46 g) = 4.82 × 10⁻³ mol
4.82 × 10⁻³ moles are dissolved in 240 mL (0.240 L) of solution. The molar concentration of perchloric acid is:
4.82 × 10⁻³ mol/0.240 L = 0.0201 M
Perchloric acid is a strong monoprotic acid, that is, it dissociates completely, so [H⁺] = 0.0201 M.
The pH is:
pH = -log [H⁺] = -log 0.0201 = 1.70
Answer:
C) differ in the arrangement of their atoms about a double bond
Explanation:
Cis-trans isomers -
Isomers are the molecules which have the same molecular formula but they differ in their arrangement of atoms.
The two isomers possible are the cis and the trans isomer .
1. Cis - isomer - The priority group or the similar group are at same side of the double bond .
2. trans - isomer - The priority group or the similar group are at different side of the double bond . ( the group are diagonally present )
Hence , the option about cis - trans isomer is ( c ) .
