# Does a balanced chemical equation obey the law of definite proportions?

## Does a balanced chemical equation obey the law of definite proportions?

Answer Expert Verified Solution: Law of conservation of matter or mass states that’ total mass of the reactants should always be equal to the total mass of the product that is the total mass is remained conserved in a chemical reaction. A balanced chemical equation always follow this law.

## Does a balanced chemical equation obey the law of conservation of mass?

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

Which type of reaction obeys the law of conservation of mass?

Following the Law Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

How does a balanced equation show the conservation of mass?

A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.

### Is the law of conservation of mass?

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

### Which chemical reaction is the fastest?

German and US scientists recently reported an unusual feat: they observed the world’s fastest chemical reaction, during which hydrogen atoms bind onto and then leave a sheet of graphene, all within ten quadrillionths (10^-14) of a second.

What would slow down a reaction?

To slow down a reaction, you need to do the opposite. Factors that can affect rates of reactions include surface area, temperature, concentration, and the presence of catalysts and inhibitors. Concentration – another way to increase the rate of a chemical reaction is to increase the concentration of the reactants.

How do you know if a reaction is slow or fast?

You can also determine which reaction is fast and which reaction is slow if you are given the rate law. Which ever reactants are present in the rate law are the reactants in the slow reaction.

## Who has the fastest reaction time?

Ingenious experiment reveals that fruit flies have the fastest reaction times of all. Reaction time is the period between a sensory stimulus and the subsequent behavioural response. In humans, the fastest reaction time is about 100 milliseconds or 0 .

## What is the slowest human reaction time?

The fastest possible conscious human reactions are around 0.15 s, but most are around 0.2 s. Unconscious, or reflex, actions are much faster, around 0.08 s because the signal doesn’t have to go via the brain.

Who has the world’s fastest reflexes?

Recently, fast reflex responses of skipper but- terflies (Hesperiidae) to the photographic flash were reported and were found to be among the fastest ever recorded (<17 ms)—comparable to the fastest reflexes of the vertebrates (Sourakov 2009).

How fast can the human brain react?

The typical reaction time for a human is about 250 milliseconds—meaning it takes you about a quarter of a second after you see something to physically react to it.

### Can thoughts travel faster than light?

(Phys.org) —Physicist James Franson of the University of Maryland, Baltimore County has captured the attention of the physics community by posting an article to the peer-reviewed New Journal of Physics in which he claims to have found evidence that suggests the speed of light as described by the theory of general …

### How fast are our thoughts?

1 to . 5 milliseconds, so the bulk of that time is spent within the axons. This is consistent with research findings that the average individual neuron sends signals at around 180 kilometers per hour. But speeds can be boosted with myelination and increased axon diameter.

What is the fastest thing humans have made?

1 Helios 2, 157078 miles per hour NASA Helios 2 space probe is the fastest man-made object ever.

What is the fastest animal on Earth 2020?

cheetah

## Is light faster than darkness?

Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. In this respect, darkness has the same speed as light.

## Is anything faster than light?

Nothing can move faster than the speed of light. When Einstein set forth his theory of relativity, this was his inviolable postulate: that there was an ultimate cosmic speed limit, and that only massless particles could ever attain it. All massive particles could only approach it, but would never reach it.

What color is darkness?

Eigengrau (German for “intrinsic gray”; pronounced [ˈʔaɪ̯gn̩ˌgʁaʊ̯]), also called Eigenlicht (Dutch and German for “intrinsic light”), dark light, or brain gray, is the uniform dark gray background that many people report seeing in the absence of light.

Does time stop for light?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.

### Does E mc2 apply to humans?

No. Not technically. Many people think mass can be converted into energy and vice versa. But E=mc^2 is the equation for mass-energy equivalence.

### What is the relationship between light and time?

The speed of light is the speed at which all massless particles travel. It is only happenstance that light was the first massless particle that we discovered, which caused c to be named after light, a name which has stuck. This is because time is like space, and moving objects are tilted in time.

Is it possible to travel back in time?

Real-life time travel occurs through time dilation, a property of Einstein’s special relativity. Einstein was the first to realize that time is not constant, as previously believed, but instead slows down as you move faster through space.

Does the past still exist?

The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.

## Can we go back in time if we travel faster than light?

Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.

## Is Time Machine already invented?

In fact, a time machine has already been built. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.

Can Time Machine is possible?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth.

Who made time machine in real life?

Ali Razeqi says his time machine uses “complex algorithms” to see the future. It’s not quite Back to the Future, but a young Iranian inventor claims to have built a time machine that can predict a person’s future with startling accuracy.

### Who invented time machine in real life?

The idea of a time machine was popularized by H. G. Wells’ 1895 novel The Time Machine. It is uncertain if time travel to the past is physically possible.
