Answer:
183.3 Km.
Explanation:
- The jet airplane reaches 846 Km in an hour (60.0 min).
- The question is what the distance the airplane covers in 13.0 min.
<em>Using cross multiplication:</em>
846 Km → 60.0 min
??? Km → 13.0 min
∴ The distance that the airplane covers in 13.0 min = (846 Km) (13.0 min) / (60.0 min) = 183.3 Km.
Explanation:
It is known that for a body centered cubic unit cell there are 2 atoms per unit cell.
This means that volume occupied by 2 atoms is equal to volume of the unit cell.
So, according to the volume density
2 atoms =
=
Formula for volume of a cube is . Therefore,
Volume of the cube =
As lattice constant (a) =
=
Therefore, the value of lattice constant is .
And, for bcc unit cell the value of radius is as follows.
r =
Hence, effective radius of the atom is calculated as follows.
r =
=
=
Hence, the value of effective radius of the atom is .
A) 60 male
B)70 Celsius
C) 15 celsius
D) 55 Celsius
E)40
F)60
G)it increased
Answer:
The answer to your question is 2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Explanation:
Original chemical equation
NaCl + H₂O ⇒ NaOH + Cl₂ + H₂
Reactant Element Products
1 Na 1
1 Cl 2
2 H 3
1 O 1
This reactions is unbalanced
2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂
Reactant Element Products
2 Na 1
2 Cl 2
4 H 4
2 O 2
Now, the reaction is balanced
