CO2, C2H2, BeF2, XeF2, etc all these molecules have linear geometry.
Alinara [238K]3 years ago

Explanation:

There are a few examples of different type of molecules that have a linear geometry:

1) Diatomic molecules

Diatomic molecules always have a linear geomerty given that its their only possiblility.

Some examples are: Oxygen (O2), Nitrogen (N2), Fluorine (F2), Choridic acid (HCl).

2) Triatomic molecules with no lone pair electrons

In this case, the absence of lone pair electrons keeps a linear geometry in molecules such a carbon dioxide (CO2).

If the molecule would have this electrons the repulsion generated between them and the electrons from the atomic bonds would create an angular geometry.

Four properties of water are listed.
kobusy [5.1K]

Answer:

It reacts with metals to form metal hydroxide and hydrogen gas. it s an chemical property and it decomposes to H2 and O2 is also another chemical property property. because in these reaction H2O has changed to something else hence are called chemical property.

A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. How
nata0808 [166]

Answer:

600.7 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

From the question,

Given: P = 190 atm, V = 35 L, T = 135 K

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (190×35)/(135×0.082)

n = 600.7 moles of xygen

A stable subatomic particle known by the symbol for "proton"

e elementary charge, p, H+, or 1H+ having a positive electric charge. Its mass is 1,836 times greater than an electron's mass and just a little bit less than that of a neutron (the proton–electron mass ratio). "Nucleons" refers to protons and neutrons together, each of which has a mass of roughly one atomic mass unit (particles present in atomic nuclei).

Each atom. has a nucleus. that contains one or more protons. In order to keep the atomic electrons bound, they offer the central attractive electrostatic force. An element's defining characteristic, known as the atomic number, is the number of protons in the nucleus (represented by the symbol Z)

Sucrose is very soluble in water. at 25◦c, 211.4 grams of sucrose will dissolve in 100 g of water. given that the density of the
stiv31 [10]
Molarity of solution is mathematically expressed as,
M = \frac{x\text{weight of solute(g)}}{\text{Molecular weight X Volume of solution(l)}}

We know that volume = mass/density
Given: mass of solution = 100 g, Density = 1.34 g/ml
∴ volume = 100/1.34 = 88.49 ml = 0.08849 l

Also, we know that molecular weight of sucrose = 342.3 g/mol
 ∴M = \frac{x\text{211.4}}{\text{342.3 X 0.08849}}
       = 6.979 M

Thus, molarity of solution is 6.979 M
