What is the volume of 2.10 moles of chlorine gas (Cl2) at 273 K and 1.00 atm?
Rasek [7]
Ideal gas law:
PV=nRT    ⇒  V=nRT / P
P=pressure=1 atm
V=volume
n=number moles=2.10 moles
R=0,082 Atm l/ºK mol
T=temperature=273 K

V=(2.10 moles*0.082 (atm l)/º(K mol)*237ºK)  / 1 atm=47.01 litres

Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? Arrange the substances with polar
KengaRu [80]

Covalent bonds can be classified as nonpolar and polar covalent given the electronegativity difference between two atoms (ΔEN).

Nonpolar covalent bond electrons are shared equally between two atoms, polar covalent bond electrons are shared unequally, atoms have partial charges, ionic bond electrons are completely transferred to one atom, full charges present. Therefore, the greater the electronegativity difference, the greater the bond polarity. Let's determine the types of bonds present in the compounds and arrange the ones with polar covalent in order of increasing ΔEN. Sulfur and oxygen are both nonmetals so the substance is covalent. Sulfur has EN = 2.5 and oxygen has EN = 3.5. Since there is an electronegativity difference, the S−O bonds in the substance can be classified as polar covalent bonds.

PLS HELP!! <br> Balance this equation: __H2+ 2 O2---&gt; 2 H2O
alekssr [168]

Answer:

 2H₂   +   O₂  →   2H₂O

Explanation:

The expression of the equation is given as:

              _H₂   +   2O₂  →   2H₂O

Now for expression above,

                           Reactants                                          Products

H                              2                                                            4

O                              4                                                           2

to balance the equation, we use 2 moles of hydrogen gas and 1 mole of oxygen gas;

           2H₂   +   O₂  →   2H₂O
