Answers

Answer 1

The order of decreasing density of the gases under STP conditions is as follows:
1) Chlorine ; 2) Neon ; 3) Fluorine ; 4) Argon

The order of decreasing density of the gases under STP conditions is as follows: 1) Chlorine (Cl2) with a density of 3.214 g/L, 2) Neon (Ne) with a density of 0.900 g/L, 3) Fluorine (F2) with a density of 1.696 g/L, and 4) Argon (Ar) with a density of 1.784 g/L. This order can be determined by using the molar mass of each gas and the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. At STP conditions, the pressure is 1 atm and the temperature is 273.15 K. The molar mass of the gases can be found in the periodic table, and using PV = nRT, the number of moles can be calculated. Then, dividing the mass by the volume will give the density.
To convert atmospheric pressure measured in mmHg to mbar, we can use the relation 1 atm = 1013.25 mbar. We know that 760 mmHg = 1 atm, so we can use this to find the pressure in atm and then convert to mbar. For example, if the pressure is 750 mmHg, we can divide by 760 to get the pressure in atm (0.987 atm), and then multiply by 1013.25 to get the pressure in mbar (1000 mbar, to 3 significant figures). Therefore, to convert pressure in mmHg to mbar, we need to multiply the pressure in mmHg by 1.333 to get the pressure in hPa, and then multiply by 10 to get the pressure in mbar (since 1 hPa = 0.1 mbar).

Answers

Explanation:

Using Charles law;

V1/T1 = V2/T2

Convert your temperatures to kelvin;

20+273=298k

60+273=333k

Then put the values the formula stated above

300/333 = V2/298

Make V2 the subject of the formula

V2= (300×298)/333

V2= 89400/333

B.anion, 8 valence electrons
C.cation, 2 valence electrons
D.cation, O valence electrons

Answers

Answer:

B

Explanation:

The [tex]\rm \bold{F^1^-}[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

An ion is defined as the atom with the change in the valence electrons by the loss or gain of electrons to complete the outer shell.

What type of ion is [tex]\rm F^1^-[/tex]?

The ions with the gain of electrons result in a negative charge and are termed anions. The ions with a loss of electrons have a positive charge and are termed cations.

The F is the halogen atom of group 17 with 7 valence electrons. The ion formed for F requires 1 electron to complete its valence shell.

The ion [tex]\rm F^1^-[/tex] has a negative charge, which denotes it gains an electron and forms anion.

The gain of electrons results in the number of valence electrons being 8.

Thus, [tex]\rm F^1^-[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?

Answers

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃   + Cu   →  Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

If we see stoichiometry, ratio is 1:2

Magnetic forces can attract or repel objects at a distance. ...

They explore attracting and repelling forces with magnets and with the simulation. ...

Magnetic forces can convert potential energy stored in the magnetic field to kinetic energy.

Explanation:

The launcher can launch the model spacecraft by exerting a magnetic force.

Magnetic force is a force just like gravity that can act across a distance without touching the object that is attracted by it. It should be noted that magnetic attraction is a pulling force.

Therefore, since the launcher wants to make the model spacecraft move without touching it, a magnetic force should be exerted on it. The magnetic force can act as the distance that's required for the objects to move.
