Standard equation: N2(g)+3H2(g)==>2NH3(g), so through stoichiometry, (13.5 mol H2)(2 mol NH3/3 mol H2), yielding 9 moles of NH3<span />

How many moles of sodium hydroxide are there in 1.0mL of 2.0M NaOH
kvasek [131]
To find the moles, you can use the following formula

moles= Molarity x Liters

Molarity= 2.0 M
Liters= 0.0010 Liters  ---------------->>>>>>>>>> 1.0 mL= 0.0010 Liters

moles= 2.0 M x 0.0010 Liters= 0.0020 moles

When NH3(g) reacts with N2O(g) to form N2(g) and H2O(g), 105 kcal of energy are evolved for each mole of NH3(g) that reacts. Wri
Ganezh [65]

Answer : The balanced chemical equation is,

2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g)+210kcal

Explanation :

Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on product side.

The given unbalanced chemical reaction is,

NH_3(g)+N_2O(g)\rightarrow N_2(g)+H_2O(g)+105kcal

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of individual elements are not balanced.

In order to balanced the chemical reaction, the coefficient 2 is put before the NH_3, the coefficient 3 is put before the N_2O\text{ and }H_2O and the coefficient 4 is put before the N_2.

The energy evolved in this reaction = 105Kcal\times 2=210Kcal

Thus, the balanced chemical reaction will be,

2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g)+210kcal

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.

Subject: chemistry  

Level: High School

Keywords: atomic number, The elemenents of the intermittent table arranged by atomic mass, atomic number speak to, Meaning of subshell.
