At what temperature is water at its greatest density
2 answers:
Answer:
Explanation:
We usually approximate the density of water to about at room temperature. In terms of the precise density of water, this is not the case, however, as density is temperature-dependent.
The density of water decreases with an increase in temperature after the peak point of its density. The same trend might be spotted if the temperature of water is decreased from the peak point.
This peak point at which the density of water has the greatest value is usually approximated to about . For your information, I'm attaching the graph illustrating the function of the density of water against temperature where you could clearly indicate the maximum point.
To a higher precision, the density of water has a maximum value at , and the density at this point is exactly

Answer:
<u>= 14.24g of </u><u> is required.</u>
Explanation:
Reaction equation:
→
Mole ratio of ammonium carbonate to carbon dioxide is 1:1
1 mole of CO2 - 44g
?? mole of CO2 - 6.52g
= 6.52/44 = 0.148 moles was produced from this experiment.
Therefore, if 1 mole of - 96.09 g
0.148 mol of -- ?? g
=0.148 × 96.09
<u>= 14.24g of </u><u> is required.</u>
Answer:
Explanation:
Hello,
In this case, the initial concentrations of hydrogen and iodine are the same:
Thus, considering the given undergoing chemical reaction, one states the law of mass action in terms of the change due to the chemical change as shown below:
Therefore, solving for by quadratic equation one obtains:
Nevertheless, the feasible result is the first one as the second one results in negative concentrations, thus, the hydroiodic acid equilibrium concentration turns out:
