Answer:
3.75 atm
Explanation:
Volume remains constant, so we can use <em>Gay-Lussac’s Law</em>.
<em>p</em>₁/<em>T</em>₁ = <em>p</em>₂/<em>T</em>₂ Multiply both sides by <em>T</em>₁
<em>p</em>₁ = <em>p</em>₂ × <em>T</em>₁/<em>T</em>₂
<em>p</em>₁ = ?; <em>T</em>₁ = 299 K
<em>p</em>₂ = 7.77 atm; <em>T</em>₂ = 620 K Insert the values
<em>p</em>₁ = 7.77 × 299/620 Do the operations
<em>p</em>₁ = 3.75 atm
The rate of a chemical reaction is the speed with which the reactants are converted to products while the collision theory is used to explain why chemical reactions occur at different rates. It states that for a reaction to proceed, the reactants particles must collide and the more successful collisions there are per unit of time, the faster the reaction will be. As the reaction progresses, the products builds up in the system and the chance that the reactants will collide amongst themselves reduces as the product molecules begin to build up while the molecules of the reactants are deprived. therefore the rate of reaction changes.
Answer:
positive(cations) and negative(anions)
Explanation:
Answer:
In chemistry the substance is usually measured using molecular mass and molar mass. They are very important concepts in chemistry. Expression of molar mass is grams per mole.
...
Molar mass:
Difference between Molar mass and Molecular mass
Measurement given to compounds, atoms or molecules Determined only in molecules
