Answer:
NO2
Explanation:
Calculate moles of Nitrogen and oxygen (assume total mass is 100g as you only have percentages therefore there is 63.6g of N and 36.4g of O) This is the ratio that they are in but you need the ratio to be in whole numbers therefore divide each number of moles by 2.275 (the moles of oxygen) to calculate the empirical formula. Hope this helps!
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:
Cold water
Explanation:
A simple way to solve this kind of problems is to keep in mind that:
<em>Solids have stronger intermolecular attractive forces than liquids, and liquids have stronger forces than gases.</em>
Cold water behaves more similarly to solids than hot water. Conversely, hot water behaves more similarly to gases than cold water. Thus, cold water has stronger intermolecular attractive forces than hot water.
They are able to be divided by a chemical reaction
