Water or also known as H2O
Answer:
s an example, the ground state configuration of the sodium atom is 1s22s22p63s1, as deduced from the Aufbau principle (see below). The first excited state is obtained by promoting a 3s electron to the 3p orbital, to obtain the 1s22s22p63p1 configuration, abbreviated as the 3p level.
Explanation:
Explanation:
the sum of PE and KE is mechanical energy this means energy during motion and position I think the answer is motion and stored or it may be internal
The mass of is K2CrO7 in the 250 ml of solution is mathematically given as
x=1.25mg of K2CrO7.
Hence, 250 ml of the solution will contain 1.25mg of K2CrO7
<h3>The mass of is K2CrO7</h3>
Question Parameters:
The total of potassium dichromate are there in a 250 mL bottle filled with 5 ppm solution
Generally the mass of k2CrO7 is mathematically given as

x=1.25mg of K2CrO7
Therefore,
250 ml of the solution will contain 1.25mg of K2CrO7
