Answer: it is just a phrase that mostly everyone uses and they know they ate to much lol
Explanation:
Answer:
6
Explanation:
The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
The complete question is;
How many Joules of heat energy would be required to raise the temperature of 16.0 g of lead from 25 degrees to its melting point of 327 degrees for a length of time long enough to completely melt the lead.
Specific heat capacity of lead is 0.159 J/gK and the molar enthalpy of fusion is 24.7 J/g
Heat is given by mcΔT
Δ T= 322 ° c = 322 +273 = 595 K
Heat = (16 × 595 × 0.159) + (24.7 × 16 )
= 1513.68 + 395.2
= 1908.88 Juoles
The desirable soil pH for corn ranges from 5.8 to 7.0.
Molar mass Zinc chloride
ZnCl2 = 65.3 + 35.5 * 2 = 136.3 g/moles
1 mole ZnCl2 ------------- 136.3 g
x mole ZnCl2 ------------- 302.48 g
x = 302.48 / 136.3
x = 2.219 moles
1 mole --------------- 6.02x10²³ units
2.219 moles --------- y units
y = 2.219 * 6.02x10²³
y =
formula units
hope this helps!.
