Solar and hydroelectric (just took test)
nikdorinn [45]3 years ago

The answer is B. Solar and hydroelectric energy are renewable sources of energy. This means that they are sustainable hence cannot be depleted since they renew themselves at sufficient rates. They have the lowest carbon footprint compared to the other choices’ combinations. Therefore due to their low greenhouse gas emissions, they contribute the least to global warming.

How does the path of the moon in the sky vary throughout the year
Kay [80]

Answer: your answer

Explanation: The Moon follows generally the same path, but with some important differences. The Moon's orbit is tilted 5.1° relative to the ecliptic. So, the Moon can appear anywhere in a band extending 5.1° north (above) and south (below) of the ecliptic. Each month, the Moon twice crosses the ecliptic on opposite sides of Earth

Which of the following ways lead to the creation of an ion? (You may select more than one option.)
tresset_1 [31]

Answer:

option A = gaining or losing of electrons

Explanation:

Ionic bond:  

When an atom loses the electrons positive ions are formed. The other atom which accept these electrons form negative ions. These positive and negative ions attract each other through electrostatic force and form the bond called ionic bond.

Ionic bond:

Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.

We know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.

But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.

Example:

Take the example of sodium that can lose one electron and form Na+. This Na+ ion is called cation because it carry positive charge by losing the one electron. This cation now contain eleven proton and ten electron.

Now consider the example of Chlorine atom. It consist of 17 proton and 17 electron. But in order to attain the noble gas configuration or to complete the octet it gain one electron and form anion (Cl-). The chlorine anion consist of 17 proton and 18 electron.

Now consider the compound formed by sodium and chlorine ions. Sodium chloride is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.

Na+ (cation)

Cl- (anion)

NaCl
