Which of the following is the long notation for 3.45 x 10^10? A 3,450,000,000 B 345,000,000,000 C 34,500,000,000

C. 34,500,000,000

Explanation:

Firstly, 3.45 x 10^10 is said to be in a standard form, which is a simpler way to write relatively large or small numbers. Standard forms make use of powers of ten, which means that how many tens can be found in such number.

The power of ten of a small number is written with a negative sign. For example; 0.004 is written as 4 × 10^-3 while the power of ten of a large number is written with a positive sign. For example; 3.45 x 10^10 means the number is large.

In order to convert a standard notation to an expanded notation, one moves the decimal point to the right by the number of times indicated on the index. For example, 3.45 x 10^10 is written as 34,500,000,000 in long notation form by moving the decimal point to the right 10 times (as indicated on the index). A zero (0) is used to fill the blank spaces when moving the decimal point.

Hence, a standard notation of 3.45 x 10^10 can be written as 34,500,000,000 in long or expanded notation. This figure is 34 trillion, 500 million.

the answer is c. it will give up it's valence electron to the other atom.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
