Answer: It will increase the rate of reaction
Explanation:
An increase in enzyme or substrate concentration will increase the rate of reaction.
What is an enzyme?An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.
Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off.
The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme.
Hence, an increase in enzyme or substrate concentration will increase the rate of reaction.

Why are microwaves idea for transmitting satellite communication signals?
Answer:
Microwaves are best suited because
they have a higher frequency and small wavelength
Satellite communication and Earth observation from space benefit from microwaves that can pass through haze, light rain, snow, clouds, and smoke. Because they can penetrate the atmosphere, microwaves are used. Small wavelength and high frequency is employed for this.
Microwaves are radio waves with short wavelengths and frequencies in the gigahertz (GHz) range. They can send signals over great distances without any data loss thanks to their high frequency. Without producing signal overlap or interference, they may carry a wide range of frequencies.
Electromagnetic radiations include radio waves and microwaves. In communication, both are utilized. Television and radio programs are transmitted by radio waves, but mobile phones and Wi-Fi use microwaves. Radio waves are one of the several alternatives for satellite communication.

what is the condensed electron configuration for nitrogen
Answer:
In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. The remaining three electrons will go in the 2p orbital. Therefore the N electron configuration will be 1s22s22p3.

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
Using two to three sentences, summarize what you investigated and observed in this lab. I investigated how chemical compounds work and what to use to put them together.
Why do you believe knowing how elements and compounds react together is essential in everyday matters? So, you can cook and stop injuries, these two things happen a lot in day-to-day life.
Some elements are more "reactive" than other elements; why do you think this is? Because certain elements in the compound may react more to fire or water and many other elements.
Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. Because if you add all the atoms, put in that’s the total amount. For example, water has one hydrogen atom and one oxygen atom, so water has two atoms.
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds, or do we have many compounds in this world? Yes, it is possible like water and hydrogen peroxide. The formula of water is H20 but hydrogen peroxide has one more oxygen-H202.

Facts about radiation in the human body
Answer:
How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
Because radiation kills rapidly dividing cells (which is why we use it to treat fast-growing cancer cells), radiation exposure most increases the risk of cancers of rapidly dividing cells — leading to leukemia, lymphoma, breast cancer, bladder cancer, colon cancer, liver cancer, lung cancer, esophageal cancer, ovarian
Explanation:
how many molecules of butane are contained in 25.0 ml of butane? the density of butane is 0.6011 g/ml and the molar mass is 58.12 g/mol.
Explanation:
To determine the molecules of butane we can either use multiple steps or use a combined equation based on the following formulas:
Molecules of butane = Moles × Avogadro's Number
Moles of Butane = Mass ÷ Molar Mass
Mass of Butane = volume × Density
∴ Molecules of butane
= [(volume × Density) ÷ Molar Mass] × Avogadro's Number
= ([(25.0 ml × 0.6011 g/ml) ÷ 58.12 g/mol] × (6.022 × 10²³ molecules/mol))
= 1.557 × 10²³ molecules
∴ 25.0 ml of butane of density of 0.6011 g/ml contains 1.557 × 10²³ molecules.From the following which is not an ore

how did dalton advance the atomic philosophy proposed by democritus
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Dalton turned Democritus' views on atoms into a scientific theory by employing experimental methods. Atoms can join or detach during chemical processes, but they never transform into a different atom.
Dalton was an excellent polymath, a natural philosopher, and a real scientist. His thorough investigations prompted him to suggest an early atomic theory for which exceptions would be difficult to uncover today:
Dalton offered the following:
Atoms are microscopic particles that make up elements. Atoms of the same element have the same size and mass; however, atoms of other elements have varying sizes and masses when compared to atoms of other elements. Subdivision, creation, and destruction of atoms are all impossible.
All of these ideas were developed after a great deal of testing. Other researchers may replicate his work, and new findings could be included into this atomic idea.
Democritus, on the other hand, was a 5th-century BC Greek philosopher. He conducted no experimental work as far as we know, and none of his publications have survived. He postulated that matter was made up of a single indivisible element known as an atom; the word atom originates from the Greek word oos, which meaning "uncuttable" or "indivisible." So the name atom might be a homage to Democritus.
the following reaction gives a product with the molecular formula c4h8o2. draw the structure of the product.
The following reaction gives a product with the molecular formula C₄H₈O₂. The diagram of the structure of the product can be seen in the image attached below.
The reaction between C₂H₂(ONa)₂ and C₂H₄Br results in the formation of the product C₄H₈O₂ and 2NaBr.
This reaction undergoes an SN₂ mechanism since there is no stable carbocation formed. In the reaction -O⁻Na⁺ attacks the ortho position in C₂H₄Br to form C₄H₈O₂.
In SN₂ mechanism is a nucleophilic substitution reaction where one bond is formed while another one is broken simultaneously.
The mechanism for the reaction can be seen in the image attached below.

The alkyl halide that forms the alkene shown as the only product in an elimination reaction is bromomethyl cyclohexane.
An elimination reaction is a reaction in which two atoms are removed to create a double bond. Elimination reaction is a type of reaction that is common to alkyl halides.
In this reaction, a hydrogen atom and a halogen atom are both removed to yield a double bond. The structure of the product depends on the structure of the reactant alkyl halide.
