Neon and Argon both are noble gas, so they have same property !!

The  gases  that has the  most similar  properties   is

Neon (Ne)  and  Argon (Ar)


<u><em>explanation</em></u>

   From  periodic  table    both Argon (Ar)  and  Neon(Ne)    are element in  group 18   which are referred  to  as  noble  gases.

Noble  gases are  inert since they have eight (8)   valence  electrons ( <em>electrons in their  outermost shell)</em>   which  make them  stable<em>(  neither gain or  lose  electrons)</em>

Assuming that all the energy given off in the reaction goes to heating up only the air in the house, determine the mass of metha
nirvana33 [79]

Answer:

0.92 kg

Explanation:

The volume occupied by the air is:

35.0m\times 35.0m \times 3.2m \times \frac{10^{3}L }{1m^{3} } =3.9 \times 10^{6} L

The moles of air are:

3.9 \times 10^{6} L \times \frac{1.00mol}{22.4L} =1.7 \times 10^{5}mol

The heat required to heat the air by 10.0 °C (or 10.0 K) is:

1.7 \times 10^{5}mol \times \frac{30J}{K.mol} \times 10.0 K = 5.1 \times 10^{7}J

Methane's heat of combustion is 55.5 MJ/kg. The mass of methane required to heat the air is:

5.1 \times 10^{7}J \times \frac{1kgCH_{4}}{55.5 \times 10^{6} J } =0.92kgCH_{4}

Afina-wow [57]

Answer:

An addition reaction

Step-by-step explanation:

In an addition reaction, two or more molecules come together to form a single product, for example,

C₂H₂ + 2Cl₂ ⟶ C₂H₂Cl₄

This reaction consists of two successive additions. The product of the first reaction becomes a reactant and adds a second molecule of Cl₂ to form C₂H₂Cl₄

    C₂H₂ + Cl₂ ⟶ <em>C₂H₂Cl₂ </em>

<em><u>C₂H₂Cl₂</u></em><u> + Cl₂ ⟶ C₂H₂Cl₄ </u>

 C₂H₂ + 2Cl₂ ⟶ C₂H₂Cl₄

What is the kinetic energy in kJ of 1 mole of water molecules (mass=18) if the average velocity is 590 m/s (1300 mph)
zubka84 [21]

Answer:

= 3132.9 Joules

Explanation:

  • Kinetic energy is the energy possessed by a body when in motion.
  • Kinetic energy is calculated by the formula; K.E = 1/2 mV², where m is the mass of the body or object, and V is the velocity.
  • Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.

In this case;

Kinetic energy = 0.5 × 0.018 kg × 590²

                        <u>= 3132.9 Joules</u>
