Answer:
Explanation:
Attach is the net ionic equation
Protons are heavy particles. Electrons are far from a nucleus. So your choice is <span>4. protons; electrons.</span>
Answer: the bottom one is wave the one above is electromagnetic and the one above is transverse
Explanation:
In chemistry Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.
Hopefully this helps!!
Using Ideal Gas Laws :
PV = nRT
Where,
P is Pressure = Not given
V is the Volume = 56L
n is number of moles of gas = Not given
R is the proportionality constant = 0.08206 L.atm/K.mol
T is the temperature = 25 + 273.15 = 298 K
Step 1:
Calculate n,
n = 2 x 15.999 = 31.998 g/mole
n (oxygen) = 64/31.998
= 2 moles of oxygen
Step 2:
Calculate Pressure,
P = nRT/V
Substitute the values,
P = 2 x 0.08206 x 298/56
P = 0.88 atm
