Answer:
d Theoretical yield
Explanation:
I took the test :)
Theoretical yield term is used to describe the maximum amount of a product that can be produced by a given amount of reactant
What is Theoretical yield?The theoretical yield is just the maximum mass of a product that a chemical reaction can produce.
Theoretical yield the amount of product produced by a perfect (theoretical) chemical reaction, not the amount that will receive from a laboratory reaction. The balanced chemical equation can be used to calculate theoretical yield, the limiting reactant's mass and relative formula mass, as well as the product's relative formula mass.

(NaOH Molar Mass! 39.997 g/mol)
What can you say about the forces between the particles of these gases)
Answer:
Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.

Write a clear scientific explanation of how and why the water ended up on the mirror and not in the tub. Be sure to include scientific vocabulary (including any phase changes that occurred and the role of kinetic energy).
Vocabulary words-
Condensation
Gas
Heat
Kinetic energy
Liquid
Steam
Vaporization
Water vapor
Answer:
The water was hot it turned into steam then turned to water vapor and the got attached to the glass and as the gas got attached the glass and it built up then became water again. As the vaporization was happening the gas was moving hence the energy building up.

A. Solids feel softer than gases.
B. Gases are darker colors than solids.
c. Solids have stronger odors than gases.
D. Gases usually weigh less than solids.
Answer:
D)Gases usually weigh less than solids.
Answer:
D) Gases usually weigh less than solids
Explanation:
Gases don't have weight and solids do which automatically makes gases lighter because they don't have a mass like a solid.

Explanation:
The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules
Answer:
Due to the presence of 4 valence electrons.
Explanation:
The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules occurs because the carbon atom has four electrons in their outermost shell and the four hydrogens has one electron each which result is a total of eight electrons distributed in four bonding orbitals making the structure of tetrahedral and the bond angles between these carbon atoms is approximately 109.5 degree.

Given that ammonia (NH3) acts as a weak base in water with a Kb of 1.8 x 10-5 at 298.0 K, calculate the pH at 298.0 K of a solution prepared by mixing 100.0 mL of a 0.050 M aqueous solution of ammonia with 20.0 mL of a 1.00 M aqueous solution of nitric acid. The final volume of the solution is 120.0 mL.
Answer:
pH = 0.903.
Explanation:
Hello there!
In this case, according to the given information about the problem, we can notice there is a reaction between nitric acid and ammonia, whereas just the H ions from the former are relevant:
[tex]NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)[/tex]
Thus, we first calculate the consumed moles of ammonia, it order to evaluate the moles after the reaction:
[tex]n_{H^+}=0.020L*1.00mol/L=0.020mol\\\\n_{NH_3}=0.100L*0.050mol=0.005mol[/tex]
It means there is a leftover of moles of hydrogen ions of 0.015mol; then, we calculate the molarity of the resulting solution as follows:
[tex][H^+]=\frac{0.015mol}{0.120L}=0.125M[/tex]
Finally, we use the formula for the calculation of the pH to obtain:
[tex]pH=-log(0.125)\\\\pH=0.903[/tex]
Which means this solution is highly acidic.

Balancee las ecuaciones químicas por el método de tanteo e identifique que tipo de reacción es: 1.1.- Cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso.
Respuesta:
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)
Explicación:
Consideremos la ecuación no balanceada que ocurre cuando cloruro férrico acuoso reacciona con carbonato de sodio sólido para formar carbonato férrico sólido y cloruro de sodio acuoso. Esta es una reacción de doble desplazamiento.
FeCl₃(aq) + Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Vamos a usar el método de tanteo. Empezaremos balanceando los átomos de C, multiplicando Na₂CO₃ por 3.
FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Luego, balancearemos los átomos de Fe, multiplicando FeCl₃ por 2.
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + NaCl(aq)
Finalmente, obtendremos la ecuación balanceada, multiplicando NaCl por 6.
2 FeCl₃(aq) + 3 Na₂CO₃(s) ⇒ Fe₂(CO₃)₃(s) + 6 NaCl(aq)

Calculate the volume that 12.5 g of carbon dioxide gas will occupy at a temperature of 45 degrees Celsius and a pressure of 1.20 atm
Answer:
[tex]V=6.2L[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to realize that we need to use the ideal gas equation in order to calculate the volume of CO2 but firstly calculating the moles:
[tex]n=\frac{12.5g}{44.01g/mol}=0.284mol[/tex]
Then, we proceed with the ideal gas equation to solve for volume:
[tex]PV=nRT=\\\\V=\frac{nRT}{P}\\\\V=\frac{0.284mol*0.08206\frac{atm*L}{mol*K}*(45+273.15)K}{1.20atm}\\\\V=6.2L[/tex]

Why do clouds appear and disappear?
Answer: Clouds are composed of liquid suspended water droplets in about a 100% RH environment. The three primary ways that clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. Many things can increase the temperature of the cloud, like the sun, or warm air radiating off of the ground. That's why low fog and clouds tend to disappear as it warms up during the day. ... The air within the cloud descends - When the air descends, it warms.

If 25.5g of sodium thiosulphate was dissolved in 40g of distilled water at 25°C,
I). Calculate the solubility of the solute in mol/dm^3
II). Calculate the solubility in g/dm^3
Answer:
Formula: Na2S2O3
we get solubility.
Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
Solution given:
mass of sodium thiosulphate [m1]=25.5g
mass of water [m2]=40g
at temperature [t]=25°C
we have
solubility in g/dm^3 :[tex] \frac{solute in gram}{solvent in gram} *100[/tex]
=[tex] \frac{25.5}{40}*100 [/tex]=63.75g /litre=63.75g/dm³solubility in g/dm^3 :63.75g/dm³
now
solubility of the solute in mol/dm^3=:63.75g/dm³/178=0.4 mol/dm³

Lewis acid-base concept have the following characteristics except:
A. formation of an adduct
B. formation of a coordinate covalent bond
C. donation and acceptance of an electron pair
D. donation and acceptance of a proton
Answer:
Option A) Formation of an adduct.
Explanation:
Lewis acid-base concept have the following characteristics except? Option A. Have a great day .
The Lewis acid -base concepts states that acid are electron acceptors and bases are electron donors. Hence, this concept is based on the donation and acceptance of electron pair. Thus, option C is correct.
What is Lewis acid -base concept ?According to Lewis concept of acids and bases acids are substances tends to accepts electrons and bases are electron donors. Therefore, Lewis acids are electron deficient or electrophiles.
Similarly Lewis bases are electron rich or nucleophiles. For example BF₃ is a Lewis acid and NH₃ is a Lewis base. Hence, BF₃ can accept electron from the lone pair of nitrogen from the Lewis base NH₃. and forms the acid-base pair NH₃ - BF₃.
Lewis acid- base concepts thus states the donation and acceptance of an electron pair. Hence, option C is correct.
