The chemical reactions differ primarily in the speed at which they take place. Some take years to attain equilibrium, while some are basically instantaneous. The rate of reaction of a given chemical reaction is the determination of the change in the concentration of the products or the change in the concentration of the reactants per unit time.  

With time, as the reaction reaches dynamic equilibrium, the concentration of the reactants, that is, A and B reduce and the concentration of the product, that is, C elevates. This is due to the fact that the chemical reactions seem to shift towards the product(s) end.

Over time, as the reaction approaches dynamic equilibrium, the concentrations of A and B will decrease and the concentration of C will increase. This is because chemical reactions tend to shift towards the side of the product(s).

Hope this helps!

What is the total number of pairs of electrons shared between the carbon atom and the oxygen atom in a molecule of methanal?
valentinak56 [21]
Answer is: between the carbon atom and the oxygen atom in a molecule of methanal there are two (2) <span>pairs of electrons.

Methanal or formaldehyde (H</span>₂C=O)<span> </span><span>is the simplest of the </span><span>aldehydes.
In methanal, bond between carbon and oxygen is double covalent bond (one sigma and one pi bond), which means there are four shared electrons or two pair of electrons.</span>

5. 1.00 mol HNO3 is treated with 4.47 g of magnesium. Calculate the number of moles of
ruslelena [56]

Answer:

The balanced equation is:

2 HNO3 + Mg ---> Mg(NO3)2 + H2

From the equation, we can see that we need twice the moles of HNO3 than the moles of Mg

Moles of Mg:

Molar mass of Mg = 24 g/mol

Moles = Given mass / Molar Mass

Moles of Mg = 4.47 / 24 = 0.18 moles (approx)

Hence, 2(moles of Mg) = 0.36 moles of HNO3 will be consumed

Number of moles of HNO3 after the reaction is finished is the number of unreacted moles of HNO3

Unreacted moles of HNO3 = Total Moles - Moles consumed

Unreacted moles of HNO3 = 0.64 moles (approx)

Since we approximated the value of moles of Mg, the value of remaining moles of HNO3 will also be approximate

From the given options, we can see that 0.632 moles is the closest value to our answer

Therefore, 0.632 moles will remain after the reaction

Give the number of significant figures in this number: 7.8 x 10¹²
denis-greek [22]
The number is written in scientific notation.


The significant figures are the numbers known precisely plus 1 digit that is uncertain.


When the numbers are expressed in scientific notation all the digits before  10^n are significant.


So, 7 and 8 are significant figures and the answer is that the number of significant figures is 2.

For each compound determine whether it is organic or inorganic. C10h16kno9s2 naaso2 hsicl3 (ch)4as2 (bio)2co3 h2p2o7 h2o co2 c6h
Sindrei [870]

a. Organic: C₁₀H₁₆KNO₉S₂; (CH₃)₄As₂; C₆H₁₂O₆

b. Inorganic: NaAsO₂; HSiCl₃; (BiO)₂CO₃; H₂P₂O₇; H₂O; CO₂

Compounds containing <em>both C and H</em> are organic.

Compounds that are <em>not organic</em> are inorganic.
