Answer:
pH=1.6
Explanation:
Recall that pH= -log [H+]
Plug the 2.5 x 10^-2 into [H+].
-log (2.5 x 10^2)
=1.6
Hoped this helped!
<h2>Let us complete it :</h2>
Explanation:
In sodium phosphide
Electrons are transferred from atoms of sodium
to atoms of phosphorous .
This transfer makes the sodium atoms to loose electrons
and the phosphorus atoms to gain electrons
As a result, the sodium and phosphorus bond strongly each other with a ionic bond .
The bond formation occurs as shown :
Sodium looses one electron to form Na⁺¹.
Phosphorous gain electrons to form P³⁻.
So, now we have :
Na ⁺ P³⁻
After criss crossing we have :
Na₃P
Answer:
7 and 11
Explanation:
The amount of sand on the beaches can be found using this formula:
volume (m3) = length (m) × width (m) × depth (m)
(6 × 108 m) × 60 m × 20 m = 7 × 1011 m3
Therefore, there would be a total of 7 × 1011 cubic meters of sand on the beaches.
Answer:
