Answer:

Explanation:

If a substance is a limiting reactants then the chemical reaction will not last a long time because the reactant has a set limit it will stop reacting with the second reactant. Hope this helped :)

Use an example how natural selection can lead to evolution

Eddi Din [679]

Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.

Need help asp will give brainliest

Levart [38]

Answer:

Explanation:

1: the sciencetific name of a giant squid is called Architeuthis

2: i dont know I think it says diet but: Giant squid mostly eat deep water fishes and other squids.
3: the range of a Giant squid can be found in oceans around the world at depths of at least 2,950 feet, but their exact range is unknown.

4, characteristics,

1: it has two large fins attached to its mantle.

2: the giant squid have many unique features, such as their ability to produce 'ink' to distract and deter predators.

facts,

1: Their eyes are the largest eyes in the animal kingdom and are about 10 inches

2: Their big eyes help them to spy objects in dark depths where most other animals would see nothing

3: Until 2005, nobody had ever seen a giant squid that was alive.

4: According to the stories, an huge squid would wrap its arms around a whale, causing a terrible fight to start.
5: Giant squid have small fins at the rear of their mantles used for locomotion.

Human IMPACT

Not only can squids and octopuses sense sound, but as it turns out, these and other so-called cephalopods might be harmed by growing noise pollution in our oceans—from sources such as offshore drilling, ship motors, sonar use and pile driving.

The rate law for 2NO(g) + O2(g) ====>2NO2(g) is rate=k[NO]^2[O2]. In addition to the mechanism, the following have been propo

pishuonlain [190]

Answer:

Mechanism (I).

Explanation:

The given chemical reaction:

2NO(g) + O₂(g) → 2NO₂(g)

The given rate equation for the reaction:

rate = k [NO]² [O₂]

The rate equation of a given chemical reaction is equal to the product of the concentration of reactants raised to the power the partial orders of reaction.

The overall rate of a given multi-step chemical reaction depends on the slowest step in the reaction mechanism.

Therefore, the slowest step of a given chemical reaction is called the rate-determining step (RDS).

The proposed reaction mechanisms:

(I). 2NO(g) + O₂(g) → 2NO₂(g)

In an elementary (single step) reaction, the rate equation can be written as:

rate = k [NO]² [O₂]

(II). 2NO (g) ===> N₂O₂ (g) [fast]

N₂O₂(g) +O₂(g) ===> 2NO₂ (g) [slow] ⇒ RDS

In an complex (multi-step) reaction, the slow step is the rate determining step (RDS). So, the rate equation can be written as:

rate = k [N₂O₂] [O₂]

(III). 2NO(g) ===>N₂(g) + O₂(g) [fast]

N₂(g) + 2O₂(g) ===> 2NO₂(g) [slow] ⇒ RDS

In an complex (multi-step) reaction, the slow step is the rate determining step (RDS). So, the rate equation can be written as:

rate = k [N₂] [O₂]²

Thus, the rate equation of the reaction mechanism: (I). is the same as the given rate law of the chemical reaction.

Therefore, reaction mechanism (I). is consistent with the rate law of the given chemical reaction.

Which of these compounds would be the best

Volgvan

Answer: 6. Rb Cl

Because, as the electronegativities of the elements, Rb and Cl, indicate this an ionic compound. Meaning that the elements are as ions ( Rb+ Cl-)., which in liquid (molten) state are charges that move freely, making the compound a good conductor of electricity.
