Answer:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
Explanation:
Unbalanced:
SeCl₆ + O₂ → SeO₂ + Cl₂
Count the atoms.
On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.
On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.
So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.
SeCl₆ + O₂ → SeO₂ + 3Cl₂
c:
Answer:
18m/s
Explanation:
Given parameters;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4s
Unknown:
Car's new velocity = ?
Solution:
We use one of the kinematics equation to solve this problem:
v = u + at
v = new velocity
u = initial velocity
a = acceleration
t = time
v = 10 + (2 x 4) = 18m/s
Answer:
the answer would be C: point source
Explanation:
because it specified the source of the pollution (manufacturing plant)
