Is N2 + H2 →NH4 a balanced chemical equation? Is it obeying the law of conservation of matter?

1 answer:

8 0

The answer is :

No, the equation is not balanced. Neither the Nitrogen (N) or Hydrogen (H) are balanced!

Here’s why:

⓵ A balanced chemical equation occurs when the number of atoms involved in the reactants side is equal to the number of atoms in the products side.

→ The equation is not balanced because in the reactants side, there are 2 Nitrogen atoms and 2 Hydrogen atoms. In the products side, there are 1 Nitrogen atom and 4 Hydrogen atoms. So the number of atoms is not balanced on both sides!

There you go! I really hope this helped, if there’s anything just let me know! ☻

How many iodide ions are present in 65.5ml of .210 m AlI3 solution

blondinia [14]

Answer:

$2.48\times 10^{22} ions$ are present in solution.

Explanation:

Molarity of the solution = 0.210 M

Volume of the solution = 65.5 ml = 0.0655 L

Moles of aluminum iodide= n

$Molarity=\frac{\text{Moles of compound}}{\text{Volume of the solution(L)}}$

$0.210M=\frac{n}{0.0655 L}$

n = 0.013755 moles of aluminum iodide

1 mole of aluminum iodide contains 3 moles of iodide ions:

Then 0.013755 moles of aluminum iodide will contain:

$3\times 0.013755 moles=0.041265 mol$ of iodide ions

Number of iodide ions in 0.041265 moles:

$0.041265 mol\times 6.022\times 10^{23}=2.48\times 10^{22} ions$

$2.48\times 10^{22} ions$ are present in solution.

draw the lewis structure for CO2, H2CO3, HCO3-, and CO3 2-.Rank these in order of increasing attraction to water molecules. Expl

gavmur [86]

Answer:

The structures are attached in file.

Hydrogen bonding and intermolecular forces is the reason for ranks allotted.

Explanation:

In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.

In order of decreasing affinity to water molecules:

$CO_{3}^{2-} > HCO_{3} ^{2-} > H_{2} CO_{3}$

This is due to the fact that the $CO_{3}^{2-}$ will accept protons more readily than the bicarbonate ion, $HCO_{3} ^{2-}$ . Carbonic acid, $H_{2} CO_{3}$ will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.

Why does 5060 have three significant figures?

Morgarella [4.7K]

<h2>5060 have three significant figures : Explanation given below </h2>

Explanation:

Significant figures

The significant figures (also known as the significant digits and decimal places) of a number are digits that possess certain meaning .

It includes all digits except: zeros

Rules to find significant figures

1.All non-zero digits are considered significant. For example, 23 has two significant figures.

2.Zeros in between two non-zero digits are significant: like in 202.1201 has seven significant figures.

3.Zeros to the left of the significant figures are not significant. For example, .000021 has two significant figures, zeros have no value .

4.Zeros to the right of the significant figures are significant.

That is the reason in number 5060 , it has 3 significant figures .
