Answer:

Explanation:

57.1 g of oxygen combines with 42.9 g of carbon

57.1/16 atoms of oxygen combines with 42.9 / 12 atoms of carbon

3.56 atoms of oxygen combines with 3.575 atoms of carbon

one atom of oxygen combines with one atom of carbon

A appears to be CO ( carbon monoxide gas )

2 )

72.7 g of oxygen combines with 27.3 g of carbon

72.7 / 16 atoms of oxygen combines with 27.3 / 12 atoms of carbon

4.54 atoms of oxygen combines with 2.275 atoms of carbon

2 atoms of oxygen combines with 1 atom of carbon

B appears to be CO₂ ( Carbon dioxide)

Determine the element of lowest atomic number that contains a complete d subshell in the ground state. element symbol:
allsm [11]

The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .  

Further Explanation:  

atomic number:  

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.  

The elemenents of the intermittent table arranged by atomic mass:  

atomic Mass    Name substance element          Number  

1.0079                          Hydrogen                            1  

4.0026                            Helium                                    2  

6.941                           Lithium                                    3  

9.0122                           Beryllium                                    4  

atomic number speak to:  

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.  

Meaning of subshell:  

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.

How many liters are in a 0.115 M solution containing 1.55 moles of dissolved KBr?
Anika [276]
13.48 is your answer.

M=moles/liters we have M=.115 and moles=1.55

Input those values into the equation
.115=1.55/L

Solve for L
1.55/.115=13.48
