o
A. Separate the particles into positive and negative charges, and increase the space between the particles
B. Separate the particles into positive and negative charges, but maintain the same space between the particles
C Decrease the velocities of the particles, and decrease the space between the particles.
D. Increase the velocities of the particles, but maintain the same space between the particles.

Answer: Here comes the role of another formula, which we refer to as the structural formula and that is CH3OH for methanol. The structural formula gives us an additional information that carbon is attached to three hydrogen atoms and one oxygen atom.

Answer:

The pair co,Ni is out of order in terms of atomic mass

Explanation:

For co,Ni

Atomic mass of Co = 58.9331 u

Atomic mass of Ni = 58.6934

For Li,be

Atomic mass of Li = 6.941 u

Atomic mass of  be = 9.012182 u

For I,xe

Atomic mass of I =  126.90447 u

Atomic mass of Xe = 131.293 u

Hence, the pair co,Ni is out of order in terms of atomic mass

Answer: Oxygen.

Explanation: The -ate is used for the ion that has the largest number of Oxygen atoms. The -ite would be used for the ion with the smaller amount of oxygen atoms.

Answer: what would swimming in mathane lake on titan feel like.

Explanation:

Both methane and titan are gases that are combustible in nature.

Those gases which are inflammable are called combustible gases.

For example:-

These gases have various uses in daily life. these uses as follows:-

The gas will mix in the lake which harms the aquatic animals. The aquatic animals have a hard time to breath.

Hence, the lake will be polluted.

Answer:

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Explanation:

The balanced reaction is:

4 NH₃(g) + 5 O₂(g) → 4 NO (g) + 6 H₂O

By stoichiometry of the reaction, the following amounts of moles participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 4 moles of ammonia produce 6 moles of water, 1.2 moles of ammonia will produce how many moles of water?

[tex]moles of water=\frac{1.2 moles of ammonia*6 moles of water}{4 moles of ammonia}[/tex]

moles of water= 1.8 moles

When 1.20 mole of ammonia reacts, 1.8 moles of water are produced.

Answer:

As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other.  The intermolecluar forces holding the molecules together become weaker.  This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.

Explanation:

Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.

Answer:

Explanation: The body is largely composed of water molecules. Each water molecule has two hydrogen nuclei or protons. MRI takes advantage of the high prevalence of hydrogen in the body and the magnetic properties of the proton in a hydrogen atom. Hydrogen atoms induce a small magnetic field due to the spin of this atom's proton.

Answer:

acid donates protons while base accept protons

Answer: 169.3 g of [tex]AlCl_3[/tex] will be produced

Explanation:

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

moles of [tex]Al[/tex]

[tex]\text{Number of moles}=\frac{50.0g}{27g/mol}=1.85moles[/tex]

moles of [tex]Cl_2[/tex]

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1 atm (STP)  

V = Volume of gas = 42.7 L

n = number of moles = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]273K[/tex]   (at STP)

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1atm\times 42.7L}{0.0820 L atm/K mol\times 273K}=1.90moles[/tex]

[tex]2Al+3Cl_2\rightarrow 2AlCl_3[/tex]

According to stoichiometry:

3 moles of [tex]Cl_2[/tex] reacts with = 2 moles of aluminium

Thus 1.90 moles of [tex]Cl_2[/tex]reacts with=  [tex]\frac{2}{3}\times 1.90=1.27[/tex] moles of aluminium  

Thus [tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product.

As 3 moles of [tex]Cl_2[/tex] give =  2 moles of [tex]AlCl_3[/tex]

Thus 1.90 moles of [tex]Cl_2[/tex] give =[tex]\frac{2}{3}\times 1.90=1.27moles[/tex]  of [tex]AlCl_3[/tex]

Mass of [tex]AlCl_3=moles\times {\text {Molar mass}}=1.27moles\times 133.34g/mol=169.3g[/tex]

Thus 169.3 g of [tex]AlCl_3[/tex] will be produced from the given masses of both reactants.
