tree rings
Explanation:
A dendrochronologist interprets tree rings to ascertain the age of a particular tree.
Dendrochronology is a a scientific process that involves the dating of tree rings to determine the age of a particular tree.
- It is sometimes called tree-ring dating.
- This method of dating is mostly applicable to woody trees that have large years of growth.
- New rings develops in order to accommodate new structural materials like the secondary xylem and phloem in them.
- The nature of this secondary growth pattern can be used to systematically determine how old a particular tree is.

Answer:
if this is balanced or unbalanced equations then this one is balanced since there is 2 H on each side and 2 Cl's on each side
Explanation:
Answer:
0.54g of Cr
Explanation:
Current (I) = 10A
Time (t) = 100s
Molecular mass of Cr = 51.996 amu
Faraday's first law of electrolysis states that
The mass of the substance (m) of a given substance deposited at an electrode is directly proportional to the quantity of electricity or charge (Q) passed
m = nQ
M = mass of the substance
n = electrochemical constant
Q = charge passed through it
Q = IT
Q = (10 * 100) = 1000C
1 moles = molarmass = Faraday's constant (96500C)
Molar mass = Faraday's constant (96500C)
51.996 g = 96500C
How many grams will be liberated with 1000C
51.996g = 96500C
Xg = 1000C
X = (1000 * 51.996) / 96500
X = 51996 / 96500
X = 0.5388g = 0.54 g of Cr will be deposited
