Explain how lowering the speed of the current that is transporting sediment could result in the deposition of that sediment.

Chemistry
1 answer:
Artist 52 [7]3 years ago
4 0

Answer:

Explanation:

In the peak stage of a flood where it current is very high,there is much deposition of sediment dumped into the stream by mainly overland flow and gully erosion.This leads to huge sediment deposition on the stream bed.

As the flood 's current reduces,competence and capacity reduces and sediments are deposited.

The alpha decay of a radioactive nuclide (X) emits a He-4 nucleus and produces an isotope of Superscript 235 subscript 92 upper
kupik [55]

Answer:

Superscript 239 subscript 94 upper P u

(plutonium-239)

Explanation:

In alpha decay, the element subtracts 4 from its mass number and subtracts 2 from its atomic number.

So if we end with Uranium-235, which has an atomic number of 92:

235+4 = 239

92+2 = 94

Element 94 is Pu, plutonium, and its mass could very well be 239 if it's an isotope. So the answer is Superscript 239 subscript 94 upper P u.

A sample of barium nitrate is placed into a jar containing water. The mass of the barium nitrate sample is 27g. Assume the water
34kurt
So we have Barium nitrate with a solubility of 8.7g in 100g water at 20°C.

using that relation
i.e.
8.7g (barium nitrate) =100g (water)
1g barium nitrate = 100/8.7 g water

27g barium nitrate = (100/ 8.7 ) × 27
= 310.34 g

therefore,
you need 310.34g of water is in the jar.

Wetlands are able to remove nutrients and chemicals from water as the water flows through the area. A developer is planning to d
MakcuM [25]

Destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

<h3>What is ecosystem?</h3>

All species and the physical environment with which they interact make up an ecosystem.

  • Nutrient cycles and energy flows bind these biotic and abiotic components together.
  • Photosynthesis brings energy into the system, which is absorbed into plant tissue.

As it is already mentioned that, water of the wetlands was carry nutrients which in turn was taken up by plants and vegetation, and if it will destroyed near a bay then the vegetation of that place will destroy as they will not get proper nutrients, which in turn also affects the ecosystem.

Hence destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

True or false? different reactions require different catalysts.
lapo4ka [179]

True, different reactions require different catalysts. Hence, option 1 is correct.

<h3>What are catalysts?</h3>

A catalyst is a substance that speeds up a chemical reaction or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.

Though a catalyst is supposed to remain unaltered at the end of the reaction, it does take part in the reaction by providing active centres for the reaction to take place.

By helping to form a suitable activated complex in the course of the reaction, the catalyst increases the rate of formation of the product, as well as its yield.

Therefore, a catalyst has to be reactant-specific to form the favourable activated complex or intermediate.

Hence, option 1 is correct.
