There are two beakers that contain the same liquid substance at the same temperature. The larger beaker is 1,000ml and the small
azamat

Answer:

Answer choice B

Explanation:

Since you do not know the volume of the liquid in each beaker, the one in the smaller beaker could have more substance and therefore more thermal energy. If they had the same amount of substance, then the more voluminous one would radiate faster. However, since you do not know this, there is no way to tell. PM me if you have more questions. Hope this helps!

Why must living things rely on thousands of catalysts for chemical reactions necessary for life?
Murrr4er [49]
Well, you don't need enzymes (biological catalysts) if you're willing to wait a century or two to digest a burger.

Without catalysts, complex reactions like digestion would take too long and the organism could not extract energy from the nutrients it eats in a practical time frame.

In addition, speed is everything in the biological world.

Some reactions and their speed relative to other organisms reactions determines who survives and who doesn't, among other aspects of life.

If a plant is slow to photosynthesize and grow in a habitat high in competition for sunlight real estate, other autotrophs will surely take over.

Does this equation obey the law of conservation of mass: 2Z + 2HCI ➡️ ZnCI2 + H2​
MAXImum [283]

Answer:

2Zn + 2HCI ➡️ ZnCI2 + H2​

LHS of equation

Z = 2

H = 2

Cl = 2

RHS of equation

Zn = 1

Cl =2

H =2

as Zn is not equal in number of atoms on both sides of the equation, the equation does not obey the law of conservation of mass

Explanation:

the law of conservation mass states that the mass of an isolated system cannot be created nor destroyed by any chemical reaction or physical transformation. thus, there must be an equal number of atoms of an element present on both sides of the equation.

<h3>What is hexadecimal system?</h3>

Hexadecimal is an easy route for addressing twofold. It is vital to take note of that PCs don't utilize hexadecimal - it is utilized by people to abbreviate parallel to an all the more effectively reasonable structure. Hexadecimal Number System is generally utilized in Computer programming and Microprocessors. It is likewise useful to portray colors on pages. Every one of the three essential tones is addressed by two hexadecimal digits to make 255 potential qualities, hence bringing about in excess of 16 million potential tones. The primary benefit of utilizing Hexadecimal numbers is that it utilizes less memory to store more numbers, for instance it stores 256 numbers in two digits while decimal number stores 100 numbers in two digits. This number framework is likewise used to address Computer memory addresses.
