Answer:
Copper carbonate undergoes thermal decomposition. The green copper carbonate decomposes when heated and forms copper oxide and carbon dioxide
Answer:
the attractive forces keep the particles together tightly enough so that the particles do not move past each other.
Explanation:
In the solid the particles vibrate in place.
The molarity of a 27%(v/v) aqueous ethanol solution is 4.63 M
calculation
convert 27%(v/v) to fraction = 27ml/100 ml
use density to convert 27ml to grams = 27 ml x0.79 g/ml = 21.33 g
find the number of moles of C2H6O
moles = mass/molar mass of C2H6O(46.07 g/mol)
moles is therefore = 21.33 g /46.07 g/mol =0.463 moles
find the molarity = moles /volume in liters
volume in liter = 100 ml/1000 = 0.1 L
molarity is therefore = 0.463 mole/0.1 L = 4.63 M
Chromosomes have hereditary function
that are capable of self-duplication and they have thread-like structures seen
inside the nucleus of plant and animal. In plants, they go through a cycle
called alteration of generation that has multicellular stages. One is sporophyte
that is a diploid, and the other is gametophyte with a haploid.
<span>Moreover, spores are produce through
meiosis so it go through a process of chromosome reduction in order to create a
haploid spores. While, gametes undergo mitosis and the structure is already a haploid,
which means that the number of chromosomes will not change in order to produce
haploid. In this case, the plant have both spores and gametes and the
similarities is that, they are both singles celled and a haploid. Therefore,
the number of the chromosome in the gametophyte generation is also 32.</span>
