Which statement best describes how a catalyst can speed up a chemical reaction?
The catalyst decreases the activation energy needed.
The catalyst increases the concentration of products.
The catalyst binds to enzymes to release substrates.
The catalyst increases the concentration of reactants.
Explanation:
The catalyst decreases the activation energy needed.
Catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.
What is catalyst?Catalyst is defined as a material that allows a chemical process to happen under new circumstances or at a typically faster rate.
It can also be defined as an additive ingredient that can speed up a reaction without being consumed during the process.
There are basically four types of catalyst.
Homogenous catalystHeterogenous catalystHeterogenized homogenous catalystBiocatalystNickel, When making margarine out of palm oil, Ni is employed. In the Haber process, iron (Fe) is employed etc. are some of the example of catalyst.
Thus, catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.

Can hydrogen peroxide be broken down by catalysts other than those found in a living system? What is/are the control(s) and why are they needed?
Answer:
Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down
Explanation:
because it contains no catalytic properties
Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.
What is a catalyst?A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.
Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).
The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.
Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.
As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.
Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.

Which of the following landforms is not made by groundwater erosion?
A. stalactites
B. stalagmites
C. mountains
D. sinkholes
Answer:
mountains?
Explanation:
Answer: Mountains
Explanation: Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns. And we know that a sink whole is also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes

Why is investment in capital goods important for a country like Japan? Japan's economy depends heavily on industry and must be modern to be competitive. Japan needs investment in capital goods to develop its rich natural resources. Investment in capital goods makes up for a poor literacy rate in Japan. Investment in capital goods makes overseas trade unnecessary.
Answer: Japan's economy depends heavily on industry and must be modern to be competitive.
Explanation:
Capital goods are referred to as the physical assets which are utilized during production process and they're simply used to produce other goods. Examples of capital goods are machinery, buildings, vehicles etc.
Investment in capital goods is important for a country like Japan because the economy of Japan depends heavily on industry and must be modern to be competitive. It is a highly industrialized country and must continually invest in order to keep up with other nations.

Answer:
A temporary lake create salt flats in Death Valley when Holocene lakes began to evaporate.
Explanation:
"Each time it has rained since, a new layer has been added. The flat is a vast area covered in salt that was deposited from evaporated water. When the water runs down the mountain, it dissolves minerals that precipitate out as the water evaporates."

What’s 2 similarities and 2 differences between the Earths layers and the atmospheric layers?
Answer:
Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.
Explanation:
The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.
