Protists belong to the group eukaryotes (having their DNA enclosed inside the nucleus). They are not plants, animals or fungi but they act like one. They can be in general subgroups such as unicellular algae, protozoa and molds.
contact metamorphism
extrusive igneous rock
chemical sedimentary rock
The right option is; chemical sedimentary rock
Chemical sedimentary rocks are rocks that are formed by precipitation of minerals from water. Chemical sedimentary rocks are also called evaporates and they are usually composed of the minerals halite (calcium chloride) and gypsum (calcium sulfate). Examples of chemical sedimentary rocks include stalactites, stalagmites, rock salt, flint, and some dolomites.
Answer:
The correct answer is option D, chemical sedimentary rock
Explanation:
Both stalactites and stalagmites are called drip stone as they are formed of the dripping water consisting of minerals. Both stalactites and stalagmites hang up from the ceiling of caves. These are also refereed to as Chemical sedimentary rocks formed by precipitation. The three major processes involved in the formation of these two rocks are –
a) Physical weathering – which disintegrates the minerals contained in the igneous, sedimentary, or metamorphic rock
b) Chemical weathering – which involves dissolution of weathered rock minerals
c) Precipitation of the dissolved minerals.
B. positively charged.
C. negatively charged.
D. not part of an electrolyte.
Answer:
The correct answer is option B. positively charged.
Explanation:
Hello!
Let's solve this!
When an atom yields its electrons, it yields part of its negative charge. Therefore, it immediately transforms into a positively charged ion.
This positively charged ion is called cation.
We conclude that the correct answer is option B. positively charged.
B. Minerals are deposited into the soil through erosion.
C. The surface area of rocks decreases because of acid rain.
D. Materials are transported through erosion and are dropped in another location.
Which of the following statements describes the process of deposition?Deposition can be best described as materials being transported through erosion that are dropped in another location, so the answer is D.
Moles are the amount of substance
the break down of CCl₄ is as follows
CCl₄ --> C + 4 Cl
in the compound CCl₄ - 1 mol of CCl₄ contains 4 mol of Cl
so for every 1 mol of CCl₄ there are 4 mol of Cl
then in 8 mol of CCl₄ - there are 4 x 8 = 32 mol of Cl
so 8 mol of CCl₄ contains 32 mol of Cl
answer is 32 mol of Cl
of chlorine are present in 8 moles of .
Further Explanation:
Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.
In , both carbon and chlorine are non-metals. Carbon has four valence electrons whereas chlorine has seven valence electrons. Both share two electrons with each other and a single covalent bond is formed between a carbon and a chlorine atom. So carbon forms four single bonds with four chlorine atoms in order to complete its octet and the octet of chlorine is also fulfilled. This bond is formed due to sharing of the electrons and therefore is a covalent compound. (Refer to the attached image)
is a covalent compound. So 1 mole of contains 1 mole of carbon and 4 moles of Cl.
Number of moles of Cl in 1 mole of = 4
So the number of moles of Cl in 8 moles of is calculated as follows:
So 8 moles of contain 32 moles of Cl.
