Answer:
B. particles in an object move faster
Explanation:
At higher temperatures, particles in an object moves faster.
Temperature is the degree of hotness or coldness of a body.
- At higher temperature, the substance is very hot.
- Temperature is related to the heat energy content of a body
- As the temperature increases, the average kinetic energy of the particles of system increases more and more.
- This is in compliance with the kinetic molecular theory of matter.
- Therefore, at higher temperatures, particles in an object move faster.
Answer:
Energy level (n = 4), d subshell (l = 2)
Step-by-step explanation:
The number in 4d tells you the energy level of the subshell: n = 4.
The letter d gives you the secondary quantum number l.
Depending on its value, the letter gives you the shape of the orbital.
l = 0 corresponds to an s orbital (spherical)
l = 1 corresponds to a p orbital (dumb-bell shaped)
l = 2 corresponds to a d orbital (four four-leaf clovers + one that looks like a dumbbell with a doughnut around its middle)
Answer:
7.12 × 10⁻³ M/s
Explanation:
Step 1: Write the balanced reaction
2 SO₂ + O₂ ⇒ 2 SO₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of O₂ to SO₃ is 1:2.
Step 3: Calculate the rate of formation of SO₃
The rate of loss of O₂ is 3.56 × 10⁻³ mol O₂/L.s. The rate of formation of SO₃ is:
3.56 × 10⁻³ mol O₂/L.s. × 2 mol SO₃/1 mol O₂ = 7.12 × 10⁻³ mol SO₃/L.s
yes, because they are combined in different ratios.
