Through absorbing nutrients and matter and the releasing new matter, usually in the form of CO2<span />
And so what are you trying to ask or are you making a statement??????????????!☺☺☺
The solution for the question is the following:
NaCO3(aq) + CaCl2 (aq) --> CaCO3 + Na2Cl(aq)
Na 2+(aq) + CO3 -2 (aq) +Ca+(aq) + 2Cl-(aq) ---> CaCO3 + Na 2+(aq) + 2Cl-(aq)
Ca2+ (aq) + CO3 2- (aq) → CaCO3 (s) would be the balanced net ionic equation.
Answer:
a. The original temperature of the gas is 2743K.
b. 20atm.
Explanation:
a. As a result of the gas laws, you can know that the temperature is inversely proportional to moles of a gas when pressure and volume remains constant. The equation could be:
T₁n₁ = T₂n₂
<em>Where T is absolute temperature and n amount of gas at 1, initial state and 2, final states.</em>
<em />
<em>Replacing with values of the problem:</em>
T₁n₁ = T₂n₂
X*7.1g = (X+300)*6.4g
7.1X = 6.4X + 1920
0.7X = 1920
X = 2743K
<h3>The original temperature of the gas is 2743K</h3><h3 />
b. Using general gas law:
PV = nRT
<em>Where P is pressure (Our unknown)</em>
<em>V is volume = 2.24L</em>
<em>n are moles of gas (7.1g / 35.45g/mol = 0.20 moles)</em>
R is gas constant = 0.082atmL/molK
And T is absolute temperature (2743K)
P*2.24L = 0.20mol*0.082atmL/molK*2743K
<h3>P = 20atm</h3>
