Answer:
Explanation:
Remember that
To convert L to mL multiply by 1,000
we know that
Gina made 9,350 mL
She packed 1.8 L of the soup in her kids' lunches
She froze the rest of the soup
step 1
Convert L to mL
step 2
To find out how many milliliters of soup did Gina have left to freeze, subtract 1,800 mL from 9,350 mL
Answer:
reactivity
Explanation:
a chemical reacting to another chemical is considered a Chemical property because chemicals react with other chemicals differently
Answer:
0.92moles
Explanation:
Given reaction:
2Fe + 3Cl₂ → 2FeCl₃
Mass of FeCl₃ = 100g
Unknown:
Number of moles of Cl₂ needed = ?
Solution:
To solve this problem, we work from the known specie to the unknown.
From the mass of the FeCl₃ given, we can solve for the number of moles of the unknown.
- Number of moles of FeCl₃;
Number of moles = 
Molar mass of FeCl₃ = 56 + 3(35.5) = 162.5g/mol
Number of moles = 
= 0.62mole
From the reaction expression;
2 mole of FeCl₃ is produced from 3 moles of Cl₂
0.62 mole of FeCl₃ will be produced from 
= 0.92mole
The number of moles of Cl₂ = 0.92moles
Answer:
Temperature affects the kinetic energy in a gas the most, followed by a comparable liquid, and then a comparable solid. The higher the temperature, the higher the average kinetic energy, but the magnitude of this difference depends on the amount of motion intrinsically present within these phases.
Explanation:
Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces. These forces keep particles close together.
