Answer:
Viscosity increases with stronger intermolecular forces
Step-by-step explanation:
<em>Viscosity</em> is the resistance of a liquid to flow.
A liquid can flow easily only if the molecules can move past each other with little resistance.
If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.
For example, the molecules in molasses have strong attractive forces, so it is quite viscous.
Your answer is B. Acid rain might destroy ecosystems and farmland
4KO₂ + 2CO₂ → 2K₂CO₃ + 3 O₂
The two chemicals that have a molar ratio of 3:4 is in equation above O₂ and KO₂
<em><u>explanation</u></em>
The molar ratio is the ratio between the amount in moles of two compounds that are involved in a chemical reaction.
In the equation above the mole ratio is determined by examining coefficient ( <em>number in front of the formula</em>)
the coefficient of O₂ is 3 while that of KO₂ is 4 therefore the mole ratio of O₂:KO₂ is 3:4
Answer:
5f14 6d10 7s2 7p6
Explanation:
This is because oganesson is a noble gas and element of group 18 which does not occur or is not produced naturally. It is produced in an experiment. It is a gas at room temperature and it has atomic number of 118. It is harmful and a radioactive gas due to it's radioactive properties and it is produced in small amound
Answer:
1.40M = [N2O4]
Explanation:
Based on the reaction:
2NO2(g) ⇄ N2O4(g)
Kc is defined as:
Kc = 5.0 = [N2O4] / [NO2]²
<em>Where [] are the concentrations in equilibrium of each gas</em>
As the equilibrium concentration of NO2 is 0.53M:
5.0 = [N2O4] / [0.53]²
5.0 = [N2O4] / [0.2809]
5.0*0.2809 = [N2O4]
<h3>1.40M = [N2O4]</h3><h3 />
