Studies have suggested that texting or using a cell phone while driving is as dangerous as: a. drinking coffee while driving b. driving with a bac of 0.08% c. speeding in rainy weather

Option (C) is the correct answer.

Explanation:

When we are talking on phone while driving then it is dangerous because then our mind gets diverted from the front of road towards the conversation. As a result, we forget to slow down, look around carefully, stop when necessary etc and therefore, all this might lead to accident.

Similarly, when its raining then also we should drive carefully because then people travelling on the road are not able to see things clearly due to the water entering in their eyes. As a result, they try to run to board a bus, train, taxi etc.

So, in that case person driving the car should watch out carefully in order to stop whenever necessary or slow down the speed.

Hence, we can conclude that studies have suggested that texting or using a cell phone while driving is as dangerous as speeding in rainy weather.

it should be p1 v1 = p2 v2

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
