The answer is ⁷¹Ga³⁺.
Substitute 28 for number of electrons, 71 for mass number, and 3 for charge on the ion. The element is Gallium and its symbol is Ga.
Answer:
The density of the liquid is 4.9 g/ml
Explanation:
Density of a liquid is usually measured by filling a beaker of known weight and known capacity (total volume in ml you can fill it) and weighing it. The difference between the total weight (beaker+liquid) and the beaker weight is the liquid weight. Finally, you must divide <em>liquid weight/volume</em> to obtain density.
For the problem:
beaker=15 g
beaker+liquid=64 g
⇒liquid= 64 g - 15 g = 49 g
density= 
= 
= 4.9 g/ml
Answer is: <span>naturally occurring solid, inorganic compound or element is mineral.
Minerals usually have </span>crystalline form, that means than crystal constituents (atoms<span>, </span>molecules <span>or </span>ions<span>) are arranged in a highly ordered microscopic structure, forming a </span>crystal lattice<span> that extends in all directions.

When hydrogen ................................... a CIS formation exist.
There are two types of formation which are possible in fatty acids, these are CIS and TRANS configurations.
A fat is described as a CIS fatty acid if its hydrogen atoms are lying on the same side of the carbon carbon double bonds. A fat is said to be a trans fatty acid, if the hydrogen atoms in its molecules are lying on the opposite sides of the carbon bonds.
When convergent happens:
•Deep ocean trenches
• volcanoes
• mountains
• earthquakes
When divergent occurs:
• new oceanic crust forms
• submarine mountain range
• volcanoes
• earthquakes
When transform occurs:
• faults
• earthquakes
• linear valleys
• stream beds split in half
