Antoine Lavoisier was able to show that mass wasn't lost or destroyed during chemical reactions by weighing all of the matter in the system before and after reactions occurred. What questions would you ask Lavoisier about how he conducted his investigations?​

Answers

Answer 1

Answer: we can ask simple qs like was it a fair experiment and what he was actually looking for. Other qs include his variables use and that how he has maintained the experiment. Finally we could ask him for his outcome and what it would ahve changed in the near future

What is chemical equation?

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Why must you continue to increase the temperature as you perform distillation ?​

Answers

Answer:

It is possible to separate several distinct compounds according to their varying volatilities by altering the temperature of the distillation process. A nonvolatile solute, on the other hand, will always remain in the solution if you have a nonvolatile solute in your solution.

Explanation:

Hope it helps:)

Answer:

The reason for this is that the composition of the vapor that is distilling varies continuously during the distillation

A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, how many moles of Gas B are present?

Answers

A flower vase placed on the table

Explanation:

A laborer pushing a crate on the table

A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, no. of moles of Gas B are 1.376.

What is combined gas law?

The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.

It is a mathematical expression that relates Pressure, Volume and Temperature.

(P1 × V1)÷T1 = (P2 × V2)÷T2

We can also use the following relation-

PV = nRT

Let n be the total no. of moles.

Given,

P = 7 atm

R = 0.0821

T = 333K

V = 16 L

n = PV / RT

n = 4.096

n = no. of moles of A gas + no. of moles of gas B

4.096 = 2.72 + x

x = 1.376

Therefore, A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, no. of moles of Gas B are 1.376.

why are metals generally good conductors of electric current?

Answers

Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.

The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.

A friend has a plan to make jewelry using rock candy and claims that the jewelry will look like and last as long as jewelry made from gemstones. Use evidence about the bonding in ionic and molecular compounds to evaluate this claim.

Answers

It is possible to form jewelry from rock candy that will look like and last as long as jewelry made from gemstones since the both materials contains a crystalline lattice.

Ionic bonding comprises of units cells of oppositely charged ions that come together to form a crystal lattice. Molecular compounds such as gemstones are also composed of unit cells which also give a well defined crystal lattice.

We must note that the strength of these materials come from the fact that all have a well defined crystal lattice in which particles are well ordered.

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

Answers

Answer:

21.2 gm

Explanation:

calculate the mass of butane needed to produce 64.1 g of carbon dioxide to three significant figures and appropriate units

butane is the hydrocarbon C4H10  

in combustion, we react hydrocarbons with O2 to form CO2 and H2O

so

C4H10  + O2---------------->  CO2 + H2O

BALANCE

2C4H10 + 1302--------> 8CO2 + 10 H2O

the molar mass of CO2 is 12 + 16X2 = 44

64.1 gm of CO2 is

64.1/44 = 1.46 MOLES OF  CO2,

FOR EVERY 8 MOLES OF CO2 WE NEED 2 MOLES OF BUTANE  IT IS A

8:2 OR 4:1 RATIO.  THE MOLES OF C4H10 ARE 1/4 THE MOLES OF CO2

SO

THE MOLES OF C4H10 H10 ARE 1.46/4 =0.365 MOLES

THE MOLAR MASS OF BUTANE IS 58.12

0.365 MOLES OF C4H10 HAS A MASS OF 0.365 X 58.12 = 21.2 gm

Is the partial pressure of o2 higher in water or the air?

Answers

Since inspired air is 21% oxygen and atmospheric pressure is 760 mmHg (at sea level), the partial pressure of oxygen is 0.21 x 760 mmHg = 160 mmHg. As air moves into the alveoli, water vapor and carbon dioxide are added, and that reduces the partial pressure of oxygen to about 100 mmHg in the alveolar gas.
