Soccer, football, and basketball
Answer:
they are carried away and deposited wherever.
there are many wanys sediments can be carried so common examples would be... by wind, water, or by animals.
Explanation:
to find the mass we multiply the number of moles with the molar mass
0.00808*195=1.5756g
Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.
Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).
Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.
Answer:
X- HCl
Y- NaOH
Z- NaCl
Explanation:
An acid turns blue litmus paper red, exhibits low pH(due to high concentration of hydrogen ions) and also react with magnesium as follows;
2HCl(aq) + Mg(s)-------> MgCl2(aq) + H2(g)
A base turns red litmus paper blue, exhibits a high pH (due to low concentration of hydrogen ions) and does not react with magnesium.
A salt does not react with litmus paper, exhibits a neutral pH of 7 and does not react with magnesium.
