In order to properly calculate how much reactant needs to be used in a chemical reaction to produce a specific amount of product

, what method of chemical calculation must be used
Chemistry
1 answer:
Alik [6]3 years ago
6 0

Answer:

First, a mandatory stoichiometric balance must be made, and second, the degree of purities and impurities that the reagents have must be analyzed to see how many products they would have.

It is essential that this is taken into account since not all chemical compounds (reactants) are 100% pure and therefore their entirety does not become a product.

Explanation:

As for the stoichiometric balance, it is fundamental since if the equation is not balanced all the data will be wrong.

Many times the quantity in grams and another measurement of the products are obtained, taking into account a standard value of how many reactants will give x quantity of products, a simple rule of three could be made and thus be able to determine in a simpler way how many reactants were catalyzed in reaction.

Which one has more mass a bag of cotton balls or a bag of nails and explain
Mama L [17]
You would think that the bag of nails would have more mass but their masses are identical. <span>If you were to put them both in a vacuum chamber and let them fall from a great height, they would fall the same speed. The vacuum chamber would suck all of the air out of the cotton balls, thus making it heavier and weigh the same as the bag of nails.

Hopefully this is helpful and makes sense.</span>

Which statement describes the reaction involved in cellular respiration?
Masteriza [31]

Answer:

i think its b

Explanation:

if you removed the C02 from the atmosphere that

willl make the 02 and it will

released for the atmosphere

which means, Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2. However, these processes are not in balance. Not all organic matter is oxidized.   photosynthesis mean if you dont know: Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.

this is why the CO2 is removed and the 02 is released into the atmosphere,   Consumers such as animals, fungi, and bacteria get their energy from this excess biomass either while living or dead and decaying. Oxygen from the atmosphere is combined with carbohydrates to liberate the stored energy. ... Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

and if the CO2 is release from the atmosphere this will happen --> Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating CO2 effects the wither,   Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts.     im sorry that i gave alot of facts my teacher said its good to add alot of facts some of my thoughts thank you i hope you get this right :)

Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?
vlabodo [156]

Answer:

Option (D) freezing point depression

Explanation:

Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.

Which statement best describes how an electromagnetic motor works?
inn [45]

Answer:

Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.

Explanation:

Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
