Answer: 6100 seconds
Explanation: 6.1 Kiloseconds = 6100 Seconds
Converting 6.1 Kilo seconds is 6100 seconds.
What are seconds?The unit of time measurement used by the International System of Units (SI) is the second (s or sec). Any specific period of time that is used to measure or represent duration on a regular basis is referred to as a unit of time.
The second is the fundamental unit of time in the International System of Units and by extension. There are different units of time. They are hour, second, and minute. 1 minute is equal to 60 seconds. 60 minutes into one hour, and 24 hours equals one day.
The unit can be converted into different units as 1 ks equals 1000 seconds. To convert a unit first determine the unit, then match the unit which others, and then know the units.
Thus, the 6.1 Kilo seconds is 6100 seconds.

Why is nitro group called an ambident group?
Answer:
An ambident ("both teeth") group is a group that can attach to another by either of two atoms. A nitro group can bond through either N or O. In organic chemistry, this property gives rise to functional group isomers.

Calculate the change in temperature of a 650. g sample of water that loses 5480. J of energy
Answer:
2
Explanation:
1) the formula of the energy is:
E=cm*Δt, where E - the value of the energy (5480 J.), c - the specific heat capacity (4200 J/(kg*C)), Δt - the difference between initial temperature and the final one (it is unknown);
2) if to perform the substitution of the values 'E', 'm' and 'c' into the formula above, then
5480=4200*0.65*Δt;
3) to calculate Δt:
Δt=5480/4200/0.65≈2 (°C).
note: the initial temperature is higher than the final.

Answer:
781×10¯² g of MgCl₂.
Explanation:
The balanced equation for the reaction is given below:
Mg + 2HCl —> MgCl₂ + H₂
Next, we shall determine the mass of HCl that reacted and the mass of MgCl₂ produced from the balanced equation. This is illustrated below:
Molar mass of HCl = 1 + 35.5
= 36.5 g/mol
Mass of HCl from the balanced equation = 2 × 36.5 = 73 g
Molar mass of MgCl₂ = 24 + (35.5×2)
= 24 + 71
= 95 g/mol
Mass of MgCl₂ from the balanced equation = 1 × 95 = 95 g
SUMMARY:
From the balanced equation above,
73 g of HCl reacted to produce 95 g of MgCl₂.
Finally, we shall determine the mass of MgCl₂ produced by the reaction of 6 g of HCl. This can be obtained as follow:
From the balanced equation above,
73 g of HCl reacted to produce 95 g of MgCl₂.
Therefore, 6 g of HCl will react to produce = (6 × 95)/73 = 781×10¯² g of MgCl₂.
Thus, 781×10¯² g of MgCl₂ were obtained from the reaction.

What is Molecular formula?Two atoms together chemically form a molecule. The chemical formula for a molecular compound's molecular formula lists the variety of atoms that make up the molecule.
A subscript under oxygen in CO2, for instance, indicates that there are two oxygen atoms present, but a subscript under carbon indicates that there is just one carbon atom present.
A nitronium salt is produced when tin(IV) nitrate and trifluoroacetic acid anhydride combine. Trifluoroacetic acid produces a similar molecule when it is solvated with it.
The number of each atom contained in a given molecule is indicated by the molecule's molecular formula. In essence, it is a list of the elements that are present in a molecule and how many of each there are.
Therefore, The formula for tin (II) nitrite Sn(NO2)2.

Using the equation below, how many liters of water can be made from 7.6 L of oxygen gas at STP?
Answer:
V = 15.2 L
Explanation:
STP means that T = 273 K and P = 1 atm.
We use the PV=nRT equation to convert the given liters of oxygen to moles:
1 atm * 7.6 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 273 Kn = 0.340 molNow we convert O₂ moles to H₂O moles, using the stoichiometric coefficients of the equation:
0.340 mol O₂ * [tex]\frac{2molH_2O}{1molO_2}[/tex] = 0.68 mol H₂OFinally we use the PV=nRT equation once again to convert 0.68 moles of H₂O to liters:
1 atm * V = 0.68 * 0.082 atm·L·mol⁻¹·K⁻¹ * 273 KV = 15.2 LHow many molecules of ammonia are contained in 10.4 moles of ammonia, NH3?

Argon has three naturally-occurring isotopes: 99.6% of 40Ar, with an atomic weight of 39.9624 amu, 0.337% of 36Ar, with an atomic weight of 35.9676 amu, and 0.063% of 38Ar, with an atomic weight of 37.9627 amu. Calculate the average atomic weight of Ar. Round off the answer to six significant figures. Do not include the units.
Answer:
39.9477amu is the average atomic weight of Argon
Explanation:
The average atomic weight is defined as the sum of the products of the atomic weight of each isotope times its abundance. For the Argon the average atomic weight, X is:
[tex]X = 0.996*^{40}Ar + 0.00337*^{36}Ar+0.00063*^{38}Ar[/tex]
[tex]X = 0.996*39.9624amu + 0.00337*35.9676amu+0.00063*37.9627amu[/tex]
X = 39.9477amu is the average atomic weight of Argon
A certain reaction with an activation energy of 185 kJ/mol was run at 505 K and again at 525 K . What is the ratio of f at the higher temperature to f at the lower temperature
Answer:
The ratio of f at the higher temperature to f at the lower temperature is 5.356
Explanation:
Given;
activation energy, Ea = 185 kJ/mol = 185,000 J/mol
final temperature, T₂ = 525 K
initial temperature, T₁ = 505 k
Apply Arrhenius equation;
[tex]Log(\frac{f_2}{f_1} ) = \frac{E_a}{2.303 \times R} [\frac{1}{T_1} -\frac{1}{T_2} ][/tex]
Where;
[tex]\frac{f_2}{f_1}[/tex] is the ratio of f at the higher temperature to f at the lower temperature
R is gas constant = 8.314 J/mole.K
[tex]Log(\frac{f_2}{f_1} ) = \frac{E_a}{2.303 \times R} [\frac{1}{T_1} -\frac{1}{T_2} ]\\\\Log(\frac{f_2}{f_1} ) = \frac{185,000}{2.303 \times 8.314} [\frac{1}{505} -\frac{1}{525} ]\\\\Log(\frac{f_2}{f_1} ) = 0.7289\\\\\frac{f_2}{f_1} = 10^{0.7289}\\\\\frac{f_2}{f_1} = 5.356[/tex]
Therefore, the ratio of f at the higher temperature to f at the lower temperature is 5.356
If 4.50 moles of HNO3 are used, how many moles of copper (II) nitrate are produced?
Answer:
2.25 moles of Cu(NO₃)₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
Cu + 2HNO₃ —> Cu(NO₃)₂ + H₂
From the balanced equation above,
2 moles of HNO₃ reacted to produce 1 mole of Cu(NO₃)₂.
Finally, we shall determine the number of mole of Cu(NO₃)₂ produced by the reaction of 4.5 moles of HNO₃. This can be obtained as follow:
From the balanced equation above,
2 moles of HNO₃ reacted to produce 1 mole of Cu(NO₃)₂.
Therefore, 4.5 moles of HNO₃ will react to produce = 2.25 moles of Cu(NO₃)₂.
Thus, 2.25 moles of Cu(NO₃)₂ were obtained from the reaction.

Which hand is negatively charged?
Option B is the correct answer .
What is Charge ?
Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Use the smallest integer coefficients possible. If a box is not needed, leave it blank.
Answer:

Explanation:
The destruction of ozone is a non-elementary reaction. This means that it does not take place in a single reactive encounter. The reaction rather takes place is a sequence of steps called the reaction mechanism.
We can see that in the overall reaction, ozone is reduced to ordinary oxygen thus the ozone layer is depleted by this reaction. It is a two step reaction as shown.
Both steps (1) and (2) are bimolecular. The equation of the net reaction is shown in the image attached.
