Answer:
Explanation:
Weathering is the breakdown of rocks into smaller particles called:
sediments
Weathering is the physical disintegration and chemical decay of rocks into smaller fragments to produce sediments. The product of rock weathering is basically sediments. Some of the sediments can be transformed to form soils when they combine with organic matter, water and air.
Physical weathering is when rocks are physically broken into smaller pieces, but the minerals in the rock remain the same.
Physical weathering
Physical weathering is the disintegration of rocks into smaller bits without altering the chemical make up of the minerals. The goal of physical weathering is to expose rock surface to action of chemical weathering.
When a rock is broken down in a way that changes the mineral composition, it is called chemical weathering
chemical weathering
Chemical weathering is the decay of rocks by altering the minerals in a rock.
Answer:True
Explanation:
Most of the transition metals—those metals in the center d-block of the periodic table—are polyvalent. Since they can form cations with different charges, those charges must be specified when naming the ions and when naming compounds containing those ions.

Answer:
Explanation:
how many grams and moles of gold are present in 8.09 x 10^28 atoms of gold?
there are 6.02 x 10^23 molecules or atoms in 1 mole
of a compound or element
8.09 x 10^28 /(6.02 x 10^23) = 1.34 x 10^5 moles of Au
1 mole of gold (see periodic table for #79) 197 g
so 1.34 x 10^5 moles of Au weigh
197 x 1.34 x 10^5 = 2.64 x 10^7 g
your little gold treasure is worth
Gold Price Per Gram $59.87 x 2.64 x 10^7=
$$$$ 1.58 x 10^9
=$ 1,580,000,000
