HELPPPPP PLEASEEE ILL MARK YOU BRAINLIESTTTTTT!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

Ionic bonding occurs when atoms either gain or lose one or more valence electrons, resulting in the atom having either a negative or positive charge.

Through ionic bonding, an atom of each element will combine with the other to form a molecule, which is more stable since it now has a zero charge.

What is the function of the phytoplankton in the ocean ecosystem
Nitella [24]

Phytoplankton is a type of micro algae. This creature is similar to the other plants in the ocean biome. But what makes it special is the fact that it is the main produce in the food web. The plant is so small that it is impossible to see it with the naked eye.

However, that doesn’t remove the fact that phytoplankton contains a huge amount of chlorophyll. Here are the 13 Function of the Phytoplankton in Ocean Ecosystem. Find out what makes this small plant so crucial to the ocean

The development of new technology requires the evaluation of the overall benefit to cost ratio of the new technology.
avanturin [10]

Answer:

B and C Reduce Emissions and Least fuel economy

Explanation:

Plug-in electric vehicles are related, fun and practical (also called electric cars or hybrid electric vehicles).  We will reduce emissions and save you even money. EVs deliver more than individual advantages.  EVs will allow the US to have a more diverse range of transportation fuel options.  Last year the US used almost nine billion barrels of oil, of which two-thirds went into shipping.  We are vulnerable to price increases and supply disruptions because of our dependence upon oil. EVs help reduce this threat, as almost all US electricity, including coal, nuclear, natural gas and renewables, is generated from domestic sources.Vehicles can also minimize the CO2 emissions, improve health, and reduce environmental damage that contribute to climate change and smog. Charging your EV for renewable, such as solar or wind, will further reduce these emissions. Link to a calculator on the right to the pollution disparity between the traditional and an EV. Discover how EV reduce pollution and their emissions during their life cycle.

Two isotopes of hypothetical element X exist with abundances of 30.00% 100X and 70.00% 101X. What is the approximate atomic mass
Rasek [7]

Answer:

C. 100.7 amu

Explanation:

Isotopes of an element are atoms of an element with the same atomic number but different atomic masses. Each atomic mass of an isotope is known as an isotopic mass. An element that exhibits isotope, that is, that have two or more isotopes has a relative atomic mass that is not a whole number.

Relative atomic mass of X is the sum of the products of the relative abundances of each isotope and its isotopic mass.

For Isotope ¹⁰⁰X: 30% × 100 = 30 amu

For Isotope ¹⁰¹X: 70% × 101 = 70.7 amu

Relative atomic mass of X = (30 + 70.7) amu = 100.7 amu

Therefore, the approximate atomic mass of X is 100.7 amu
