This is a physical phase change it is still water it just separated and became less and less.it stays water though
Answer:
Observe: To model how hydrogen and oxygen react to make water, type “H2+O2” into the Reactants box and “H2O” into the Products box.
As the equation is written, which element is not in balanced?
oxygen isn't balanced...
Explanation:
in reactants there is 2hydrogens and 2 oxygen
but in product there is balanced no if hydrogen bt there is only one no of oxygen
169.32 grams of NH3 ........
One of the differences I can think of is that hydrogen is no longer listed as a group I element.
According to the mendeleev tables that I looked up, hydrogen is catorgrized as a group I element, along with Lithium, sodium, Potassium etc. However, nowadays, hydrogen does not belong to any groups in the periodic table. This is because there are arguments about whether hydrogen belongs to group I. Group I elements are all alkali metals, while hydrogen is not. However, some people says that hydrogen only have one outer shell electron so it should be in group I. Some people even say hydrogen should belong to group VII because it only needs one more electron in order to achieve the duplet of electrons.
Therefore as you may notice, hydrogen in modern periodic tables are put in the center of the periodic table on the top.
Answer:
0.0064 qt
Explanation:
Given data:
Density of mercury = 13.6 g/cm³
Mass of mercury = 83.0 g
How many quarts mercury have = ?
Solution:
First of all we will calculate the volume in cm³.
d = m/v
13.6 g/cm³ = 83.0 g / volume
Volume = 83.0 g / 13.6 g/cm³
Volume = 6.1 cm³
cm³ to L:
6.1 cm³ × 1 L / 1000 cm³
0.0061 L
In quarts:
1 L = 1.06 qt
0.0061 L × 1.06 qt / 1 L
0.0064 qt
