<span>Chemical formula of ammonia = NH3
As we can see there are three atoms of hydrogen in one molecule of ammonia.
So in the 200 molecule of ammonia there will be = 200*3 = 600 atoms of hydrogen.
Answer - 600 atoms of hydrogen.</span>

Answer:</h3>
Ammeter
<h3>
Explanation:</h3>
- Lets ask ourselves the following questions
What is an Ammeter?
- An ammeter is a device that is used to measure electric current in a circuit.
How is it used ?
- To measure the electric current the ammeter is placed in series with the components of the circuit and the reading on the ammeter is taken.
What is electric current?
- Electric current is a measure of the flow of electrons in a given circuit per unit time. It is therefore, the measure of the rate of flow of electrons in a circuit.
Answer:
The answer is "Only at the end, a transformation of rose to color is made
".
Explanation:
In this student puts its vinegar in the titrator, and NaOH throughout the beaker, which implies phenolphthalein has also been poured into water.
Phenolphthalein does have a pH range of 8.3-10 (approx). It's indeed pink in the basic medium therefore, the formulation becomes pink throughout the color by adding phenolphthalein to NaOH.
It is beginning of vinegar was its beginning of neutralization of NaOH from the titrator through full neutralization, a single piece of vinegar is added to a solution as well as the rose solution is lost throughout the beaker.
Answer:
See explanation.
Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary for us to set up the equilibrium reaction by which chromium (II) iodide is ionized as follows:

Thus, it is possible to notice that the the moles, and therefore concentrations, of chromium(II) and iodide ions are going to be different, by a factor of 2 due to the mole ratio in the aforementioned chemical equation.
