The correct answer is false. A compound microscope can magnify something up to 200 times and further. A compound microscope is a microscope with more than one lens and its own source of light. Today's strongest compound microscopes have magnifying powers of 1000 times to 2000 times.

The correct answer is False

Explanation:

A microscope is an instrument used in many scientific fields including biology and chemistry to magnify the image of an object and therefore study and look at it, which is not possible without a microscope due to the limitations of the human eye. Additionally, a compound microscope is a type of microscope that includes multiple lenses to magnify objects and therefore, allows scientist to observe the same object with different sizes. About this, it is important to mention the range objects can be magnified depends on the type of microscopes but in general terms, this type of microscope include lenses that magnify objects from 10 times to around 400 times, and especial microscopes can magnify objects up to 1000 times. Thus, it is false a compound microscope can magnify something only up to 200 times.

Calculate the molecular (formula) mass of each compound: (a) iron(ll) acetate tetrahydrate; (b) sulfur tetrachloride; (c) potass
Nutka1998 [239]

Answer:

a) Iron(ll) acetate tetrahydrate: 245,68 g/mol

b) Sulfur tetrachloride: 173,87 g/mol

c) Potassium ermanganate 158,034 g/mol

Explanation:

To solve this kind of exercises you must look for the number of atoms in each molecule first, then look on the periodic table the atom weight and the multiply the atom weight times the quantity of each atom. For instance:

The molecule of Iron(II) acetate itetrahydrate is (CH3COO)2Fe•4H2O, it means that you have:

2 atoms of carbon times the atomic weight of C (12.00g/mol)= 24g

14 atoms of Hidrogen times the atomic weight of H (1,00g/mol)= 14g

6 atoms of Oxigen times the atomic weight of O (16,0g/mol)= 96

2 atoms of Iron times the atomic weight of Fe (55,84g/mol)= 111,68g

At last, you only have to add the results: 24+14+96+11,68= 245,68g/mol. This example was for the first molecule.

See you,

Answer: C) a redox reaction that produces an electric current

Explanation:

Chemical cell is a device which is used for the conversion of the chemical energy produced in a redox reaction into the electrical energy. The cell consists of the negative terminal called as anode where oxidation takes place and a positive terminal called as cathode where reduction takes place.

Electrolytic cell is a device which is used to carry out chemical reactions by the use of electrical energy. The cell consists of the negative terminal called as cathode where reduction takes place and a positive terminal called as anode where oxidation takes place.
