what is the mass in kilograms of 25L of hydrophosphoric acid?
Answer:
0.0345kg is the mass of 25L of the sample
Explanation:
Hydrophosphoric acid, H₃P = Phosphine has a density of 1.38g/L.
To solve this question we need to convert the volume of the gas to mass in grams as first and then to kilograms as follows:
Mass in grams:
25L * (1.38g / L) = 34.5g
Mass in kilograms:
34.5g * (1kg / 1000g) = 0.0345kg is the mass of 25L of the sample

When ethane (C2H6) burns, it produces carbon dioxide and water:
2C2H6(g)+7O2(g)→4CO2(g)+6H2O(l)
How many moles of water will be produced when 3 moles of ethane are burned?
3 moles
6 moles
9 moles
12 moles
Answer:
6 moles
Explanation:
According to stoichiometry and given chemical equation 2C₂H₆(g)+7O₂(g)→4CO₂(g)+6H₂O(l), 9 moles of water are produced when 3 moles of ethane are burned.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is important while balancing chemical equations.
In the given problem , as 2 moles of ethane produce 6 moles of water so according to stoichiometry
∴ 3 moles of ethane will produce 3×6/2=9 moles
Thus, 9 moles of water are produced when 3 moles of ethane are burned.

Organisms that are made up of prokaryotic cells are NOT ____________.
Question 3 options:
Bacteria
Multicellular
Simpler than organisms made up of Eukaryotic celled organisms
All of these are true about prokaryotic cells
Answer:
Multicellular
Explanation:
Prokaryotic cells are unicellular because the do not have a nucleus and lack organelles, while eukaryotic cells do have a nucleus, have organelles, and are are multicellular. :)
Organisms that are made up of prokaryotic cells are NOT
Multicellular.
Classification of Organisms based on cellular organisation.Living organisms can be classified based on their cellular organisation.
Organisms that are made up of one cell are known as unicellular organisms.
Organisms that are made up of more than one cell are known as multicellular organisms.
A prokaryote is an organism that lacks distinct nucleus while eukaryote is an organism that possess a nucleus that is enclosed in a nuclear envelope.
While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular.
Therefore, organisms that are made up of prokaryotic cells are not multicellular.

On a recent day the difference between the lowest temperature at the highest temperature of the day was 9*C. By how many degrees fahrenheit did the temperature change
Answer:
48.2 Fahrenheit
Explanation:
Temperature change = 9*C
By how many degrees Fahrenheit did the temperature change?
The relationship between Fahrenheit and degree Celsius is given as;
F = (9 / 5) C + 32
Inserting the value of C;
F = (9 / 5) * 9 + 32
F = 48.2 Fahrenheit

Calculate the concentration of a solution of sodium chloride if 15g are added to water to make a 200cm³ solution. The answer shoulsd be in units of g/dm³.
Answer:
75 g/dm³
Explanation:
The following data were obtained from the question:
Mass of solute (NaCl) = 15 g
Volume of solution = 200 cm³
Concentration (in g/dm³) =?
Next, we shall convert 200 cm³ to dm³. This can be obtained as follow:
1000 cm³ = 1 dm³
Therefore,
200 cm³ = 200 cm³ × 1 dm³ / 1000 cm³
200 cm³ = 0.2 dm³
Thus, 200 cm³ is equivalent to 0.2 dm³.
Finally, we shall determine the concentration of the solution as follow:
Mass of solute (NaCl) = 15 g
Volume of solution = 0.2 dm³
Concentration (in g/dm³) =?
Concentration (in g/dm³) = mass / volume
Concentration (in g/dm³) = 15 g /0.2 dm³
Concentration (in g/dm³) = 75 g/dm³

Hund's rule tells us that 1) any orbital in a given subshell must first be occupied by a single electron before being occupied by a second electron and 2) the electrons in a singly occupied orbital all have the same spin.
Diagram I follows both 1 and 2; there are no prematurely-filled orbitals (boxes), and all the singly-filled 2p orbital have the same spin (the arrows are all pointing up). So, diagram I follows Hund's rule and is correct.
Diagram II violates 1: the first box in the 2p subshell is doubly filled while there's still a vacant orbital. That second electron in the first box should be in the third box and pointing upward for diagram II to be correct. Thus, diagram II violates Hund's rule and is incorrect.
Diagram III follows rule 1 but violates rule 2: While every 2p orbital is singly filled, they do not all have the same spin. In the second box, the arrow is pointing down while the arrows in the other two boxes are pointing up. Thus, diagram III violates Hund's rule and is incorrect.
So, of the diagrams given, II and III do not follow Hund's rule and thus are incorrect.
why hydrogen and oxygen atoms are more stable when they form bonds in a water molecule?
The outer shell of electrons is full, so there is no need to gain or lose electrons.
The hydrogen and oxygen atoms are more stable in water molecules as they get a complete valence shell when they bonded with other atoms.
What is the reaction to the formation of water?In a chemical reaction, two or more reactants react with each other under the chemical condition to form two or more products. The Chemical reaction is defined as a reaction two or more reactant components react with each other to form two or more products.
The water is formed by reacting hydrogen and oxygen. The chemical reaction of water formation is shown below.
[tex]H_2(g)+O_2(g)\longrightarrow H_2O(l)[/tex]
The balanced chemical equation can be defined as a reaction where the number of moles of reactants is equal to the number of moles of products.
[tex]H_2(g)+ \frac{1}{2}O_2(g)\longrightarrow H_2O(l)[/tex]
The hydrogen atoms have one electron and the oxygen has two electrons less than the complete valence shell. But in the water molecule, every atom has a complete valence shell so atoms become more stable.
