You can consider the density
of the water. Thus, in order to properly measure the mass of a liquid, we can
first get the volume and density of the liquid material or substance.
We can firstly utilize the
formula to get the mass from deriving the set formula of density to mass:
Since density is mass over the
volume,
<span><span>
1. </span>D=m/v</span>
<span><span>
2. </span>We can transmute the formula to m = dv</span>
<span><span>3. </span>Mass is density times the volume</span>
The answers are;
2H2+O2===>2H2O
N2+3H2==>2NH3
C3H8+5O2==>4H20+3CO2
CH4+2O2===>CO2+2H2O
2HBr +Fe==>FeBr2 +H2
I hope it helped
Answer:
A. substance Y will float on top of substance X.
Explanation:
If an objet is more dense that other, the first one will sink because it weights more per militer, as you can see in the image below. In our case, Substance X is heavier than Y, that means that X will sink = Y will float.
Answer:
C)
Explanation:
(A) Cover the chamber. => <u>It helps to keep the solvent in his gas state</u>
<u />
(B) Gently swirl the solvent in the chamber prior to placing the TLC plate inside => <u>The mechanical energy can promote the conversion from the liquid state to the gas state and help to the saturation process.</u>
<u></u>
(C) Add ninhydrin (a visualization technique) to the developing solvent =><u>There is no change in the saturation process</u>
(D) Place a paper wick (like a piece of filter paper) inside the chamber=><u>Increases the area for evaporation. The solvent can go up across the paper by capillarity a then can be evaporated increasing the saturation in the chamber.</u>
