Answer: Option E. There are covalent bonds between the hydrogen atoms
Explanation:
A volcanic <em>eruption</em> occurs when the <em>pressure </em> in a magma <em>chamber</em> becomes so great it is released like a valve. Magma is released through the volcano's <em>cone</em> in an eruption of <em>lava</em> rocks (bombs) and ash. A volcanic <em>cone</em> develops over centuries as flowing <em>lava</em> from the active volcano <em>cools </em>to form layers of rock.

The amount of current required to produce 75. 8 g of iron metal from a solution of aqueous iron (iii)chloride in 6. 75 hours is 168.4A.
The amount of Current required to deposit a metal can be find out by using The Law of Equivalence. It states that the number of gram equivalents of each reactant and product is equal in a given reaction.
It can be found using the formula,
m = Z I t
where, m = mass of metal deposited = 75.8g
Z = Equivalent mass / 96500 = 18.6 / 96500 = 0.0001
I is the current passed
t is the time taken = 75hour = 75 × 60 = 4500s
On subsituting in above formula,
75.8 = E I t / F
⇒ 75.8 = 0.0001 × I × 4500
⇒ I = 168.4 Ampere (A)
Hence, amount of current required to deposit a metal is 168.4A.

Range means the difference between the highest and lowest number. So subtract 25 - 14 which gives you 11.
Answer:
You determine the number of protons by its atomic number, just like electrons.
