According to the information provided in the image the emergence of photosynthetic organisms contribute to the weathering of rock was

option B was the correct answer

what does weathering of rock refers to ?

Rock Weathering: Weathering is the transformation of rocks into more stable materials as a result of exposure to agents such as air, water, and organic fluids. No rock is impervious to weathering.

                                                         or

Weathering is the process through which rocks disintegrate and decompose in situ. It signifies that weathering is a static process. Weathering, as defined by C.D. Oilier (1969), is "the breakdown and modification of minerals near the earth's surface to produce products that are more in balance with freshly imposed physico-chemical circumstances."

The rock was formed when oxygen reacted with other elements to form earths crust which weathered the rock.

that is the oxygen that is produced from the photosynthetic process was reacted to the hydrogen that is present in the gases formed the water and that lead to the weathering of the rock.

How does a catalyst speed up a chemical reaction? A. by lowering the activation energy B. by lowering the ΔH of the reaction C.
netineya [11]

Answer:

A. by lowering the activation energy

Explanation:

  • Adding a catalyst has this effect on activation energy. A catalyst provides an alternative route for the reaction with a lower activation energy. <em>As illustrated in the attached image.</em>
  • This means that more particles have the activation energy required for the reaction to take place (compared to without the catalyst) and so the speed of the reaction increases.

If you begin with 72 grams of Nickel, how many moles of Ni would you have?​
Marianna [84]

Answer: 1.2 Moles of Nickel

Explanation:

So you have to transfer grams to moles.

You do this by dividing your beginning mass by the atomic mass of the element (found on the periodic table).

1 mole is equal to the atomic mass of the element. The atomic mass of Nickel is 58.6934 rounded to the proper significant figures will be 59.

72 Grams Nickel / 59 grams = 1.2 moles of Nickel
