Answer:
the answer is decaying wood
Answer:
-2
Explanation:
Gibbs free energy is defined by enthalpy of the system minus the product of the temperature and entropy and represented by the formula below:
G = H - TS where G = Gibbs free energy, H = enthalpy and T = temperature and S = entropy
change in entropy is defined by the formula below
ΔG = ΔH - Δ(TS) if the temperature is not constant, but if the temperature is constant then
ΔG = ΔH - TΔS
in according to the question (TS) is treated together.
to the solution
increase in H = 10 units , increase in the product of temperature and entropy = 12 units
ΔG = 10 - 12 = -2
Kinetic energy is the energy of moving things
Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
Explanation:
The balanced chemical reaction for the described reaction above is,
Na2CO3 + 2HCl ---> 2NaCl + H2CO3
From the reaction, 1 mole of Na2CO3 is needed to produce 2 moles of NaCl. In terms of mass, 106 grams of Na2CO3 are needed to produce 116.9 grams of NaCl. From this,
(23.4 g NaCl) x (106 g Na2CO3 / 116.9 NaCl = 21.22 g Na2CO3
Thus, approximately 21.22 g Na2CO3 is needed for the desired reaction.
