Answer:Examples of tipping points are everywhere: a glass falling off a table upon tilting; a bacterial population hitting a level where it pushes your body into fever; the boiling point of water, or a cube of ice being thrown into warm water, where it rapidly melts.

Answer:

A IPCC AR5 climate tipping point is a critical stage at which global or regional climate shows a major change. 

Explanation:

The atmosphere framework expresses that the exact degrees of environmental change adequate to trigger a tipping point stay unsure, yet that the hazard related to intersection different tipping focuses increments with rising temperature.

Examples are melting of Arctic sea, Collapse of coral leaf due to global warming, eutrophication of the lake, Forest loss, lack of rain, Ocean warming, changes in the temperature of the Ocean current etc.

Which event would be impossible to explain by using John Dalton’s model of the atom?

geniusboy [140]

The scientist thought that the atom was the smallest particle in the universe is John Dalton. He established the atomic theory which consists of five; elements are made of extremely small particles called atoms, atoms of different element have different sizes, mass and physic – chemical properties, atoms cannot be divided further, destroyed or created, atoms can combine to form compounds and in chemical reaction, atoms can be combined, separated or rearranged.

What is Δn for the following equation in relating Kc to Kp?2 SO2(g) + O2(g) ↔ 2 SO3(g)23-2-11

san4es73 [151]

Answer:

-1

Explanation:

The relation between Kp and Kc is given below:

$K_p= K_c\times (RT)^{\Delta n}$

Where,

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

$2SO_2_{(g)}+O_2_{(g)}\rightleftharpoons2SO_3_{(g)}$

Δn = (2)-(2+1) = -1

Thus, Kp is:

$K_p= K_c\times (RT)^{-1}$

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.

adelina 88 [10]

Answer: Linear

Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.
