Answer from: blackops7777

Explanation:

Atomic number of carbon is 6 and its electronic distribution is 2, 4. This means that there are 4 valence electrons present in a carbon atom. Hence, in order to complete its octet it needs to gain 4 more electrons.

Whereas atomic number of hydrogen atom is 1. As in the given molecule there are only two carbon atoms. So, both of them will chemically combine together by sharing of one electron.

Hence, each carbon atom will be attached to three carbon atoms. In total there will be six hydrogen atoms.

Hence, the molecule will be $H_{3}C-CH_{3}$ .

The maximum number of hydrogen atoms that can be covalently bonded in a molecule containing two carbon atoms is 6.

To determine the number of possible covalent bonds, we need to consider the octet's rule: atoms will gain, lose or share electrons to fulfill their valence shell with 8 electrons. In the case of the covalent bonds, atoms will share 1 pair of electrons per covalent bond. Exceptionally, hydrogen needs only 2 electrons to fulfill its valence shell.

Carbon has 4 valence electrons and hydrogen has 1 valence electron. Then, each carbon atom can form 4 covalent bonds to reach its octet and each hydrogen atom can form 1 covalent bond to complete its duet.

Given 2 carbon atoms, and considering that they will form 1 covalent bond between them, each carbon atom can form 3 covalent bonds with hydrogen atoms, resulting in a total of 6 hydrogen atoms in the molecule. The compound formed is a hydrocarbon named ethane with the formula C₂H₆.

The maximum number of hydrogen atoms that can be covalently bonded in a molecule containing two carbon atoms is 6.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

What happens when the atmosphere interacts with biosphere

Answer from: Quest

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. $hbr$ completely dissociates to $h^+$ and $br-$ ions. a is incorrect because $h_2s$ does not fully ionize to $h^+$ and $hs^-$ ions and some remain as the compound $h_2s$ . c and d are incorrect because, $li_2o$ and $libr$ do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise, if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both $li_2o$ and $libr$ have a complete octet so can not accept any electrons which disqualifies them as acids.

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.
