The theoretical yield of 18 gram of is 162 gram of .
The amount of a product produced by a reaction is generally expressed as a percentage of the reaction's yield. The amount of product that stoichiometry predicts is known as the theoretical yield, but the amount that would be actually achieved is known as the actual yield.
The balanced chemical equation is :
→
It is known that the molar mass of water is 18 gram /mol and 2 gram per mole of .
18g (1 mol (/2 g ()(2 mol / 2 mol ()(18 g /1 mol ) = 162 g .
Theoretical yield will be 162 gram.
So, the theoretical yield of 18 gram of is 162 gram of .

<u>Satelites</u> are a type of space technology utilizes the electromagnetic spectrum to collect information.
Explanation:
Depending on the electromagnetic spectrum that the satellite is designed for, it can be utilized for a certain scientific function. The Hubble Telescope, for example, is designed to perceive the visible light spectrum of electromagnetic radiation to provide the beautiful pictures of space we see today. Some satellites that orbit teh earth are sensitive to infra-red radiation and are used to monitor earth’s atmospheric and ocean temperatures. Some satellites are designed for X-rays and gamma rays and are used to search for supernovae.
Correct answer: Galvanic cell
Reason:
Following are the differences between Galvanic cell and electrolytic cell:
1. <span>Galvanic cell converts chemical energy into electrical energy , on other hand <span>electrolytic cell converts electrical energy into chemical energy.
2. In galvanic cell, </span></span><span>redox reaction is spontaneous and is responsible for the production of electrical energy. in electrolytic cell, t<span>he redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
Thus, galvanic cell </span></span><span>refers to an electrochemical cell that produces an electric current</span>
Answer:
gains 2 electrons. In order for the new ionic compound to form a a neutral compound, the oxygens must gain 6 electrons
Answer:
the valence electrons of atoms in a pure metal can be modeled as a sea of electrons
