To determine the limiting reagent of the given reaction, we need to compare the amounts of each reactant and their respective stoichiometric coefficients. One is present in a smaller amount
The reactant that is completely consumed and limits the amount of product that can be formed is the limiting reagent.In this case, we have 76.4 g of C2H3Br3 and 49.1 g of O2. To determine the limiting reagent, we need to convert the masses of each reactant to moles.
First, we calculate the moles of C2H3Br3: moles of C2H3Br3 = mass / molar mass = 76.4 g / (molar mass of C2H3Br3)
Next, we calculate the moles of O2:
moles of O2 = mass / molar mass = 49.1 g / (molar mass of O2)
Now, we compare the moles of each reactant to their stoichiometric coefficients in the balanced equation. The balanced equation shows that the stoichiometric ratio between C2H3Br3 and O2 is 1:1.
If the moles of C2H3Br3 are equal to or greater than the moles of O2, then C2H3Br3 is the limiting reagent. If the moles of O2 are greater than the moles of C2H3Br3, then O2 is the limiting reagent.
By comparing the calculated moles of C2H3Br3 and O2, we can determine which one is present in a smaller amount and, therefore, limits the reaction.

Answer:
alligators protect their offspring by digging a hole where they bury their eggs and stay all the meanwhile on top of the hole protecting their offspring. baby alligators can be eaten by birds and snakes. they for short periods of time take a break to hunt for food. when their hatchling hatch they keep them in their mouth until they're in the water. alligators are good protecting their offspring.
seahorses make the males take care of their baby's till they are born and male seahorses join together in groups to help protect eachother. once the babies are born male seahorses are still together helping raise their pups
Alligators bury their eggs in a hole that they have dug, and they then spend the entire time on top of the hole guarding their young. Therefore, by below given ways animals take care of their offspring.
What is offspring?Offspring refers to the new organism that an organism creates via the act of reproduction. Both birds and snakes can consume young alligators. They stop for brief periods of time to go food hunting. They hold their hatchlings in their mouths until they are in the water after they hatch. Alligators do a superb job of safeguarding their young.
Male seahorses form groups to assist defend one another, and they are required to care for their young until they are born. Male seahorses continue to work together to nurture their young after the babies are born.

how many moles of oxygen gas are produced in the decomposition of 5.00g of potassium chlorate?
Given: KClO3= O2+KCl
Answer:
0.0612 moles of O2 produced
Explanation:
First we convert from grams of Potassium Chlorate to moles..
Amu = 122.5
5.00g / 122.5 g = 0.0408163265 moles of Potassium Chlorate
Now we need to use the chemical equation to find the ratio of Potassium Chlorate to Oxygen... But first, we need to balance it
Original Chemical Equation : KClO3 = O2 + KCl
Balanced Chemical Equation : 2KClO3 = 3O2 + 2KCl
Now we will use the balanced chemical equation to find the ratio of Potassium Chlorate to oxygen (in order to convert to moles of oxygen for our answer)
We can see that for every 2 moles of Potassium Chlorate that are decomposing, we have 3 moles of oxygen gas produced.
So, we will set up our conversion factor like this:
0.0408163265 moles KClO3 * 3 moles Oxygen
-------------------------
2 moles KClO3
When we solve for this, we see that there are 0.0612244898 moles of O2 produced, or 0.0612 moles of O2 produced

The interconnected, continuous processes that move water through Earth's spheres
Water changing from liquid to gas and back to liquid
The chemical components that make up water
Answer:
I think option B , bcz it is continuous process
The continuous, interconnected processes that move water through Earth's spheres best describe the water cycle. Therefore, option B is correct.
What is the water cycle?The water cycle can be demonstrated as the continuous movement of water from the Earth's surface to clouds and from clouds to the back surface. The sun, air, and other factors are included in the physical process of the water cycle, water goes through each of the states of matter such as solid, liquid, as well as gas.
The water cycle is a combination of the physical processes where water evaporates from the earth's surface into the atmosphere, cools down, condenses produces rain in clouds, and again comes back to the surface of the earth with the precipitation process.
Water on the Earth's surface of the water after rain gets collected in the form of rivers, groundwater, ponds, etc., and combines in oceans and gets evaporated.
The evaporation process includes the exchange of water from the surface in the form of water vapors to the atmosphere. The process of evaporation cools the temperature of the atmosphere as the sunlight on the surface of the earth makes the warm.

Answer: "The microscopic size of cells enable them to function properly.
Most organisms on Earth are multi-celled." is false
Explanation:
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. This is achieved by the highly regulated process of cell proliferation. The growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms.

Answer: i gotcu the answer is mass
Explanation: The more weight of the object the more its subject to gravity like a feather barley is while a bowling ball smashes into the ground :D
The property allows objects to be subject to gravity is mass. Therefore, option B is correct.
What is mass ?Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term.
The strength of an object's gravitational attraction to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit. The amount of matter object present is also known as mass.
The amount of matter that makes up every item or body is the greatest way to understand mass. Everything that we can see has mass. Examples of objects with mass include a table, a chair, your bed, a football, a glass, and even air. The mass of a thing determines whether it is light or heavy.
