I think it is the gas and the heat in it
Answer : The concentration of are 0.127 ppm, 0.127 ppm and 0.254 ppm respectively.
Explanation : Given,
Mass of =
Volume of solution = 2.25 L
First we have to calculate the concentration in terms of g/L.
conversion used :
As we know that,
1 mg/L = 1 ppm
0.127 mg/L = 0.127 ppm
So, the concentration will be 0.127 ppm.
The concentration of in ppm is, 0.127 ppm.
Now we have to calculate the concentration of and .
We assume that, dissociates 100 % in the solution then the balanced reaction will be:
From the reaction we conclude that the mole ratio of is, 1 : 1 : 2. So,
The concentration of = 0.127 ppm
The concentration of = 2 × 0.127 ppm = 0.254 ppm
organic chemistry, the hydroboration–oxidation reaction is a two-step organic reaction that converts an alkene into a neutral alcohol by the net addition of water across the double bond. The hydrogen and hydroxyl group are added in a syn addition leading to cis stereochemistry. Hydroboration–oxidation is an anti-Markovnikov reaction, with the hydroxyl group attaching to the less-substituted carbon.
Answer:
The metals in this group are lithium, sodium, potassium, rubidium, cesium, and francium. The gas hydrogen is also put in this group because it shares similar reactivity with the alkali metals.
I don't know if this is what you wanted or not sorry if it isn't
The independent variable as we can see from the experiment that have been described in this case is the brand of fertilizer that was used in the study.
<h3>What is an experiment?</h3>
When we talk about an experiment, we are talking about the way by which the relation ship between the dependent and the independent variable could be studied. In the experiment, there is a dependent variable which would change values when the variable that is under study in the particular experiment changes value. We have to know that in the realm if science, it is only by the means of experiments that we can be able to establish cause and effect relationships.
In this case, we can see that the experiment that the students were working on has to do with trying to actually find out if brand X fertilizer will affect the growth of Lily plants. This means that they were studying the effect of a fertilizer brand on the growth of the crops.
