250.00 mL) x (1.0 M ) / (2.5 M) = 100 mL
So take 100 mL of 2.5 M HCl and dilute it to 250 mL.
If data results a reproducible but not accurate, it means that there was a high level of precision, but not complete accuracy.
Answer:
ΔG ≅ 199.91 kJ
Explanation:
Consider the reaction:
temperature = 298.15K
pressure = 22.20 mmHg
From, The standard Thermodynamic Tables; the following data were obtained
The equilibrium constant determined from the partial pressure denoted as 
can be expressed as :
= 0.045
where;
R = gas constant = 8.314 × 10⁻³ kJ
199.912952 kJ
ΔG ≅ 199.91 kJ
Answer:
The coefficients in order are 2, 1, 1
Explanation:
Each side of the reaction needs to have the same number of each element due to conservation of matter.
First I looked at what was uneven, notice there are 2 Na on the left side and 4 Na on the left. The easiest way to fix that is to add a 2 on the Na2HPO4:
2(Na2HPO4)--> Na4P2O7 + H2O
Next take count of each element on both sides to see if the 2 balanced everything:
On the left there are 4 Na, 2 H, 2 P, and 8 O
On the right there are 4 Na, 2 H, 2 P, and 8 O
Since both sides match, you are done!
