once an enzymatic reaction is completed, the enzyme releases what?

Answers

Answer:

Once an enzymatic reaction is completed, the enzyme releases substrates.

Explanation:

The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

I would say D) A new substance is formed with different properties.

It doesn't nesisarally have to have a specific change (except mass), but it could be a wide variety of changes.

Answer:

A New substances form with different properties

Explanation:

When two different chemical substances are combined, they form new substances with different properties. The properties may be modified and the substance formed may exhibit better characteristic than individual properties of its components. For example, when sodium and chlorine combine, they form sodium chloride. Sodium chloride has different properties than any of the constituents.

Why are engineers called applied scientist?

Answers

Answer:

Applied science is a discipline that is used to apply existing scientific knowledge to develop more practical applications, for example: technology or inventions. In natural science, basic science (or pure science) is used to develop information to explain phenomena in the natural world.

Answer:

• Because engineers apply science and its theories into practical situation

Take an example of;

→ A generator: When creating a generator, electromagnetic induction theorem is applied. [ self and mutual inductance ]

→ A plane: The wings are made in considerance of Bernoulli principle and viscous drag

if a light wave has a wavelength of 5.80x10^-7 what is its frequency

Answers

Speed = v = 3×10⁸ m/s

Wavelength = λ = 5.8×10⁻⁷ m

Frequency = f

v = fλ

Hence,

f = v/λ

f = 3×10⁸ / 5.8×10⁻⁷

f = 0.517×10⁸⁺⁷

f = 5.17×10¹⁴ Hz

i hope this will help but if im wrong then it will be 5.16x10¹⁴

Copper occurs naturally as a mix of two isotopes: Copper-63 with a mass of 62.930 amu and copper-65 with a mass of 64.928 amu. The percent abundance of copper-63 is 69.09%.
Calculate the atomic mass of copper.

Answers

Take the weighted average of the individual isotopes.Explanation:63Cu has 69.2% abundance.65Cu has 30.8% abundance.So, the weighted average is 62.93×69.2% + 64.93×30.8% = 63.55 amu .If we look at the Periodic Table, copper metal (a mixture of isotopes but 63Cu and 65Cu predominate) has an approximate atomic mass of 63.55 g⋅mol−1 , so we know we are right.

Answer: 63.55

Explanation:

The attached chart shows the calculation. The orange line points to the % abundance of Cu-65, which is the difference of 100% less the % Abundance of Cu-65 (since there are only 2 isotopes).

The weighted average contribution of each istope is calculated (blue arrow) and then summed to find the atomic mass of copper.

Scientists use measures of velocity in everything from figuring out how much rain is falling to sending a rocket to space.
