Answer:

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. This is also useful for describing the chemical bonds that hold atoms together.

Answer:

0.0125mol/dm³

Explanation:

Given parameters:

Mass of carbon dioxide  = 0.22g

Volume of water  = 400cm³

Unknown:

Concentration in mol/dm³ =  ?

Solution:

Concentration is the amount of solute dissolved in a solvent.

The formula is expressed as;

    Concentration  = [tex]\frac{number of moles}{volume}[/tex]  

Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

       Molar mass of CO₂   = 12 + 3(16) = 44g/mol

Number of moles  = [tex]\frac{0.22}{44}[/tex]   = 0.0005mol

Now,

             1000cm³  = 1dm³

             400cm³ = [tex]\frac{400}{1000}[/tex]  = 0.4dm³

Insert the parameters and solve;

     Concentration  = [tex]\frac{0.005}{0.4}[/tex]  = 0.0125mol/dm³

Hi, the given question is incomplete, the complete question is:

It takes 4.37 J of heat to raise the temperature of Object A by 1°C, and 2.88 J to raise the temperature of Object B by 1°C. Suppose A and B are brought into contact. A is initially hotter. A is seen to cool down by 6.3°C . How would you calculate the rise in temperature of B?

Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

Answer:

The correct answer is 9.56 degree C.

Explanation:

Based on the given information, the given object A is initially hotter than object B, and the direct contact between them permits the transfer of heat between them. Based on the law of conservation of energy, the energy cannot be created nor be destroyed. In the given case, the energy, which is lost from object A can only be gained by object B.

Let us consider that both the objects exhibits equal mass, now in order to determine the transfer of energy between them there is a need to multiply the heat capacity with the temperatures. Therefore,

Energy lost by object A = Energy gained by object B

Heat capacity of object A × Temperature lost by object A = Heat capacity of object B × Temperature gained by object B

4.37 J/°C × 6.3 °C = 2.88 J × Tb

Tb = (4.37 J/°C × 6.3° C) / 2.88 J

Tb = 9.56 °C

Answer:

P₂ = 1.03 atm

Explanation:

Given data:

Initial pressure = 1.00 atm

Initial temperature = 293 K

Final temperature = 303 K

Final pressure = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.00 atm / 293 K = P₂/303 K

P₂ = 1.00 atm × 303 K / 293 K

P₂ = 303 atm. K /293 K

P₂ = 1.03 atm

Answer:

6 Cl atoms

Explanation:

In one molecule of ZnCl2, we have 2 atoms of Cl

Therefore, in 3 molecules of ZnCl2, we'll have 3(2) atoms of Cl = 6 atoms of Cl.

Answer:

Gas(this is because we are only considering that there are 3 states of matter, while in reality there are 5.)

Explanation:

There are actually 4 states of matter excluding a 5th one that has just been discovered, but if we consider that there are only 3 states of matter then the particles move the fastest in gases. As the particles are the furthest apart.

A gas produced in a chemical reaction can be collected by water displacement. Because the gas is collected over water, it is not pure but is mixed with vapor from the evaporation of the water. Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor.

Explanation:

oxygen gas is collected bye the downwards displacement of water. because it is only slightly solube in water and is less dence than water. this is my answer

Answer:

Convert grams of Mg to moles

Explanation:

In stoichiometric calculations, the first thing is always to balance the chemical reaction equation. However, in this particular instance, the equation is already balanced; 2Mg + O2 ---------->2MgO as shown in the question.

Hence, what Niven now has to do is to convert grams of Mg to moles so that the amount of MgO obtained can be calculated and subsequently converted to mass.

Answer:o It is important to realise that mixing will be small unless there are electrons in the 4a1 LUMO, this is why NH3 is pyramidal while BH3 is planar! ... This mixing is very strong and stabilises the 3a1 MO substantially and hence NH3 is trigonal pyramidal and not planar.
