Answer:
b)The molar mass of the particles.
Explanation:
The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law), a relationship that closely approximates the rate of diffusion. As a result, light gases tend to diffuse and effuse much more rapidly than heavier gases.
Global cooling was a hypothesis of the looming cooling of the Earth's surface and atmosphere that would take place over a period of substantial glaciation.
It emerged as a result of a drop of temperature during the period of 1940s and 1970s. After this it was realized that it is not a big threat as global warming.
On the other hand, Global warming is the rise in overall temperature of the atmosphere which is caused by greenhouse effect that is as a result of rise in the levels of greenhouse gas emissions such as CFCs and carbon dioxide.
Global warming is a present threat in the society world over with the rise in temperatures and climatic changes taking place, this is the reason why global warming replaced global cooling.
In chemistry, the elements that exist with electrical charges are called ions. These ions can carry a positive charge, for which they are called cations, or a negative charge, for which they are called anions. These ions carry an electric charge because they do not conform to the stable number of electrons of their neutral atom. Because of this, they carry excess electrons for cations, and a lack of electrons for the anions.
When cations and anions form together such that there is a complete transfer of electrons so that each ion would be neutral, an ionic bond is formed. If you write the reaction, the superscripts and subscripts would just cross-multiply. If the cation is A⁺ᵃ, and the anion is B⁻ˣ, then the ionic compound would then be AₓBₐ. Of x=a, then they will cancel out which will yield AB. Therefore, the ionic compound for each pair of ions are:
NH₄⁺ + OH⁻ = NH₄OH
Mg²⁺ + CO₃²⁻ = MgCO₃
Fe³⁺ + PO₃⁴⁻ = Fe₄(PO₃)₃
Answer:
CsNO₃
Explanation:
The reactants are:
Cesium chloride = CsCl
Silver nitrate = AgNO₃
Products:
Silver chloride = AgCl
The other product:
Now;
CsCl + AgNO₃ → AgCl + ?
The other product is CsNO₃
So;
CsCl + AgNO₃ → AgCl + CsNO₃
