8 groups, 1 to 7 and most people call group 8 group 0 because the noble gases in group 0 have the outer electron shell full, so for example argon has 18 electrons, so it’s structure is 2.8.8 with its outer shell full. Also the number of the last shell defies what group it’s in, for example sodium is in group 1 so it’s structure is 2.8.1. Hope this helps.

Briefly describe the movement of water through the water cycle
kotegsom [21]

1) Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Solar radiation is the source of energy for evaporation.

2) Condensation is phase change process in which the water changes from a gas to a liquid, the vapor becomes a cloud.

3) Precipitation is falling of the condensed water vapor as rain, snow, fog drip.

The water cycle (hydrological cycle) is the continuous movement of water all around the Earth.

initial volume of the argon sample = 5.93L according to Boyle's law

What is Boyle's law ?

Boyle's law, also known as Mariotte's law, is a relationship describing how a gas will compress and expand at a constant temperature. The pressure (p) of a given quantity of gas changes inversely with its volume (v) at constant temperature, according to this empirical connection, which was established by the physicist Robert Boyle in 1662. In equation form, this means that pv = k, a constant.

According to Boyle's law

P1/V1 = P2/V2

P1 = initial pressure

P2 = final pressure

V1 =initial volume

V2= final volume

V1 = P1*V2/P2

V1 = 2.32*18.3/7.16 = 5.93L

initial volume of the argon sample = 5.93L according to Boyle's law

Answer:

ok :)

Explanation: genetically modified organisms (GMOs) are being made by inserting a gene from an external source such as viruses, bacteria, animals or plants (etc) into foods. Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah
