The sand is the residue and a mixture of salt dissolved in water is the filtrate
Answer:
since the movie was unlisted, i'm unable to provide you with a proper answer? sorry
Explanation:
PV=nRT
p = 1,5atm = 1,5*101325 = 151987,5 Pa
V = 11,9l = 0,0119m3
n = ?
R = 8,314 J/mol*K
T = 20°C = 20+273 = 293K
pV=nRT
151987,5*0,0119 = n*8,314*293
1808,6513=n*2436,002 ||:2436,002
0,7425 = n >>> moles of CO2
1 mole of CO2 = 44g
1 mole of CO2--------------44g
0,7425 moles of CO2----------x
<u>x = 32,67g of CO2</u>
Answer:
the atom is neutral, the nucleus is positive
Explanation:
Answer: 0.45 J / g °C
Explanation: solution attached.
Heat is equal to the product of mass, specific heat and change in temperature.
Q= mc∆T
Derive the equation to find c
c = Q / m∆T substitute the values
c = 21.6 J / 2.0g ( 24°C - 5°C)
c = 0.45 J / g ° C
