what will be the reading on the ammeter A² be?
and pls answer quickly with explaining the formula
Answers
No need formula to explain this since it's mainly theory.
In a series circuit, the reading on the ammeter stays the same throughout, this is since current (in the circuit) doesn't change in a series circuit.
so A1 = A2 = An (n meaning any number of ammeters within the circuit)

How many moles are in 5.4 x 10-7 grams of silicon dioxide, SiO2 ?
Answers
Answer:
there are [tex]\sf 9*10^{-9}[/tex] moles in grams [tex]\sf 5.4 * 10^{-9}[/tex] of silicon dioxide.
Explanation:
[tex]\boxed { \boxed{ \sf moles = \sf{\frac{mass}{Mr}} }}[/tex]
we should know that:
[tex]\sf molar \ mass \ of \ SiO2 = 60[/tex][tex]\sf given \ mass \ of \ SiO2 = 5.4 * 10^{-7}[/tex]using the formula:
[tex]\sf moles = \frac{mass}{Mr}[/tex]

[tex]\sf moles = 9*10^{-9}[/tex]
N2 + 3H2 2NH3
Using the balanced equation above for the production of ammonia from nitrogen and hydrogen, how many moles of NH3 are produced when 1.7 moles of nitrogen reacts with hydrogen?
Answers
Answer:Considering the N2 only, 3 mols of N2 could form 6 moles of NH3. Considering the Hydrogen only, 8 moles of H2 could make 16/3 or 5 1/3 moles of NH3. 5 1/3 is less than 6, so the reaction is limited by the hydrogen, and 5 1/3 is the correct answer. Note that in reality this reaction does not go to completion, and this is just a textbook exercise.

What are two ways you can tell that steel wool went into a chemical reaction
Answers
Answer:
Two ways that I can tell is that rusting is a chemical reaction because it is not caused by any physical force or trauma it's oxidation and it changes colors from heat and heat is one of the main factors for a chemical reaction.
Explanation:
Answer:
Explanation:
Touching the battery to steel wool sends a current through the thin wire, and it heats up a lot (to about 700 degrees C). These temperatures cause the iron to react with the oxygen (O2) in the air and creates iron oxide (FeO2).
A boy of mass 60 kg and a girl of mass 40 kg are together and at rest on a frozen pond. What is the initial momentum of the boy?
A. 0 kgm/s
B. 60 kgm/s
C. 100 kgm/s
D. 10 kgm/s
Answers
The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.
Momentum can be defined as the product of mass and velocity. The S.I unit of momentum is kgm/s.
The initial momentum of the boy can be calculated using the formula below.
Formula:
M' = muWhere:
M = Initial momentum of the boyFrom the question,
Given:
M = mass of the boy = 60 kgU = Initial velocity of the boy = 0 m/s (at rest)Substitute these values into equation 1
M = 60(0)M = 0 kgm/sHence, The initial momentum of the boy is 0 kgm/s the right option is A. 0 kgm/s.

How does extreme pressure affect the volume occupied by a real gas compared to the predictions of the ideal gas law? (3 points)
Group of answer choices
The true volume of the gas will be higher than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.
The true volume of the gas will be lower than predicted by the ideal gas law because the attraction between the particles is weaker under high pressure.
The true volume of the gas will be higher than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.
The true volume of the gas will be lower than predicted by the ideal gas law because the volume of the actual particles is more significant under high pressure.
Answers
At a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.
Behavior of gases at low pressure and high pressuresAt low pressure, the distance between gas molecules is relatively far apart, but as the pressure of the gas increases, the distances between theses gaseous molecules becomes smaller.
Due to the high pressure the volume occupied by the gas molecules becomes significant compared with the volume of the container.
As a result, the total volume occupied by the gas will be greater than the volume predicted by the ideal gas law.
Thus at a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.

Answer: The fourth answer
Explanation:
Under high pressure, real gases deviate from ideal gas behavior as their particles have a finite size and experience intermolecular forces, causing the actual volume of the gas to be lower than predicted by the ideal gas law.

A sample of a compound weighing 416 grams decomposes into 143 grams of iron and 273 grams of chlorine. The
percent composition of these products is
iron and chlorine. Using these values, we can
determine that the empirical formula of the compound is Fe CI
Use the periodic table to help you find the molar masses.
Answers
1. The percentage composition of iron in the compound is 34.4%
2. The percentage composition of chlorine in the compound is 65.6%
3. The empirical formula of the compound is FeCl₃
1. How to determine the percentage of ironMass of compound = 416 gMass of iron (Fe) = 143 gPercentage of iron (Fe) =?Percentage of Fe = (mass of Fe / mass of compound) × 100
Percentage of Fe = (143 / 416) × 100
Percentage of Fe = 34.4%
2. How to determine the percentage of chlorine Percentage of Fe = 34.4%Total percentage = 100%Percentage of chlorine (Cl) =?Percentage of Cl = 100 – 34.4
Percentage of Cl = 65.6%
3. How to determine the empirical formula Fe = 34.4%Cl = 65.6%Empirical formula =?Divide by their molar mass
Fe = 34.4 / 56 = 0.614
Cl = 65.6 / 35.5 = 1.848
Divide by the smallest

A chemist burns 650.0 g of C4H8S2 in excess oxygen, according the following balanced chemical reaction:
C4H8S2+ 902 -> 4CO2 + 4H2O +2S03
If the chemist has 92.2% yield, how many grams of SO3 were produced?
Answers
Answer:
952.2g SO3
Explanation:
Molar mass of C4H8S2 is 120.2363 g/mol
Mol in 750.0g = 750.0/120.2363 = 6.238 mol
1mol C4H8S2 produces 2 mol SO3
6.238 mol will produce 2×6.238 = 12.476 mol SO3
Molar mass SO3 = 32+3×16 = 80.0g/mol
Theoretical yield = 12.476×80.0 = 998.08g
The actual yield is 95.4%
Actual mass-produced = 95.4/100×998.08 = 952.2g SO3 produced

what is the Lewis dot structure for NOH3
Answers
In this structure, Nitrogen (N) has a lone pair of electrons, Oxygen (O) has a lone pair of electrons, and each Hydrogen (H) atom has two electrons and no lone pairs.
The Lewis dot structure for [tex]NOH_{3}[/tex] (nitrosamine) can be determined by following a few steps:
Count the total number of valence electrons in the molecule. Nitrogen (N) contributes 5 valence electrons, Oxygen (O) contributes 6 valence electrons, and Hydrogen (H) contributes 1 valence electron each. So, the total number of valence electrons is:
5 (N) + 6 (O) + 3 (H) = 14 valence electrons.
Identify the central atom. In this case, Nitrogen (N) is the central atom since it can form more bonds compared to Oxygen (O).
Connect the atoms using single bonds. In [tex]NOH_{3}[/tex], Nitrogen (N) is bonded to Oxygen (O) and three Hydrogen (H) atoms.
Place the remaining electrons around the atoms to complete their octets. Start by filling the octet of the atoms bonded to the central atom, and then distribute the remaining electrons to satisfy the octet rule. If there are extra electrons, place them on the central atom.
