The pressure 80.0 meters under water is 886 kpa. what is the pressure in atm? and in mmhg

1 kPa = 0.00986923 atm

∴ 886 kPa × 0.00986923 atm/ 1 kPa ≅ 8.74413778 atm

we are given our known measurements in 3 sig figs... so...

--> 886 kPa ≅ 8.74 atm

1 atm = 760.0 mmHg

∴ 8.74 atm × 760.0 mmHg / 1 atm ≅ 6642.4 mmHg

(again, 3 sig figs means...)

---> 886 kPa ≅ 6.64 × 10³ mmHg

Hope this helps!! ^_^

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

→

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
