When calculating the amount of product formed during alcohol fermentation, one mole of ethanol is chemically equivalent to what volume of CO2 (g) measured at 1 atm and 273 K
Answer:
44.8 dm^3
Explanation:
The equation for the fermentation of glucose is;
C6H12O6 -----> 2C2H5OH + 2CO2
This means that two moles of ethanol carbon dioxide are produced.
If 1 mole of gas at STP occupies 22.4 dm^3, then two moles occupies; 22.4 dm^3 × 3 = 44.8 dm^3
URGENT!!!! How many molecules of carbon dioxide are produced when a molecule of C7H15 combusts?
Answer:
7 seven
Explanation:
because when C7H15 is heated 7molecules of atoms are displaced
Para preparar 1 kilogramo de arcilla se requieren 400 gramos de agua. Si a nivel del laboratorio solo se cuenta con una probeta y sabemos que la densidad del agua es 1100Kg/m3 ¿Cuántos litros de agua se deben añadir?
Answer:
0.364 L
Explanation:
Para resolver este problema es necesario expresar la densidad en g/L.
Para hacer esa conversión primero convertimos m³ en L:
1 m³ = 1000 L1100 [tex]\frac{kg}{m^3}* \frac{1m^3}{1000L}[/tex] = 1.1 kg/LY después convertimos kg en g:
1.1 kg/L * [tex]\frac{1000g}{1kg}[/tex]= 1100 g/LFinalmente dividimos la masa deseada (400 g) entre la densidad, para calcular el volumen:
400 g ÷ 1100 g/L = 0.364 L“True or False”

Which of the following is a possible compound formed from Ca2+ and NO3-1?
F Ca2NO3
G Ca(NO3)2
H Ca3NO2
J CaNO
Answer:
Ca(NO3)2
.................
Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.
Ions, which are charged atoms of elements come together to form ionic compounds. A positively charged ion called cation reacts with a negatively charged ion called anion to form a neutral ionic compound i.e. compound with a charge of 0. In this question, cation Ca²+ reacts with anion NO3-. The ionic compound formed must have a net charge of 0. This can only happen if 2 moles of NO3- and 1 mole of Ca²+ is present in the compound. The resulting ionic compound can be chemically represented as Ca(NO3)2. Therefore, Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.Learn more at: https://brainly.com/question/11148793?referrer=searchResults
Where do most earthquakes occur? Where do most volcanoes occur? Why do they occur here?
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire
Explanation:
Answer:
Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

kindly mark as brainliest answerA cross section of bone tissue is illustrated here. What statements accurately describe the cells shown here? You may select as many as are correct A) These cells form a type of connective tissue in the body B) This tissue can be found as compact on spongy in the body C) These cells have high concentrations of phosphate and calcium minerals D) The bone cells comprise a combination of nervous and muscular tissue in the body
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the illustration (diagram or figure). However, general understanding of the bone cells can help answer the question.
Bone cells come together to form a connective tissue called bone. The bone is a connective tissue that contains cells and other substances. The bone assists in the storage of minerals, providing of support to the body, protecting internal organs and providing attachment for muscles and tendons. The bone can be either compact or spongy (cancellous). The spongy bone is lighter and less dense than the compact bone. The bone is primarily composed of a mineral called hydroxyapatite (made of calcium and phosphorus) but also contains other minerals (such as magnesium and sodium). Hence, the bone cells are also expected to have high concentration of the minerals of hydroxyapatite (calcium and phosphorus).
The bone cells cannot however comprise a combination of nervous and muscular tissue because a cell is the structural unit of life and cannot as such comprise of a higher structure. Thus, options A, B and C are correct.

What is Zeff of phosphorus
Answer:
Explanation:
Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.
We have that The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80
[tex]Z_{eff}=4.8[/tex]
It is important to note that the Z_{eff} of an element can be defined simply as the average positive charge felt by an shell electron in an atom from the various electrons around it
Hence
The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80

For complete combustion of an organic compound needs 8 molecules of oxygen, what could the formula of this compound be?
Answer:
C5H12.
Explanation:
The compound will be C5H12.
Now consider the general formula for the combustion of an alkane;
CnH2n+2 + 3n+1/2O2-----> nCO2 + (n+1) H2O
If we substitute n=5, we have;
C5H12 + 8O2-----> 5CO2 + 6H2O
Hence the answer above.
