<em>Chemical</em> <em>weathering</em> affects hillslope form by directly removing mass from hillslopes. The transformation of primary minerals to secondary minerals can also affect the hydrology, biota, and stability of hillslopes, which in turn influence sediment transport and landscape morphology. Erosion in evolving landscapes can modulate and be modulated by chemical weathering; for example, pulses of accelerated erosion can lower the residence time of hillslope materials, thereby increasing their chemical weathering rates, which in turn accelerate the incision signal.

How many moles are in 2.3 grams of phosphorus

dmitriy555 [2]

Molar mass of phosphorus (p) : 30.9 g/mol

1 mole P ----------- 30.9 g
x mole -------------- 2.3 g

30.9 * x = 2.3* 1

30.9 x = 2.3

x = 2.3 / 30.9

x = 0.07 moles

Solution A has a mass of 70 g. Solution B has a mass of 35 g. When they are mixed, a chemical reaction occurs in which a gas is

Nuetrik [128]

Mass of gas produced : 15 g

<h3>Further explanation </h3>

In general, the reaction takes place in the open air. If the reaction results in the form of gas as in combustion, the mass of the reaction results will be smaller than the original mass.

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same

So In a closed/isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Mass of reactants :

Mass of solution A = 70 g

Mass of solution B = 35 g

Mass of products :

Mass of mixture : 90 g

Mass of gas : X

Mass of gas X :

$\tt mass~reactants(mass~A+mass~B)-mass~products(mass~mixture+mass~gas)\\\\mass~gas=(70+35)-90\\\\mass~gas=15~g$

HOW DOES ENERGY FROM THE<br> SUN ULTIMATELY CAUSE THE<br> BLADES ON THESE WIND<br> TURBINES TO MOVE?

Anarel [89]

Energy in wind comes from the sun. for example, when the Earth’s surface absorbs the suns energy, it turns to heat. wind is produced by uneven heating from the earths surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. The blades on the wind turbine move from the wind. i hope that made sense, if it didn’t i’m sorry, i hoped that hep though!

A person slips over banana pills. Give reason

zhenek [66]

Answer:

We slip when we step on a banana peel because the inner side of banana peel being smooth and slippery reduces the friction between the sole of our shoe and the surface of road.
