Which two substances are covalent compounds? * C6H12O6(s) and KI(s) C6H12O6(s) and HCl(g) KI(s) and NaCl(s) NaCl(s) and HCl(g)
Ray Of Light [21]

Answer: Option (b) is the correct answer.

Explanation:

A covalent compound is defined as the compound in which sharing of electrons take place between the combining atoms. Generally, when two or more non-metals chemically combine together the it will lead to the formation of a covalent compound.

For example, C_{6}H_{12}O_{6} and HCl is also a covalent compound.

And, a compound in which transfer of electrons occur between the combining atoms is known as an ionic compound. Whenever, a metal chemically combines with a non-metal then it will always lead to the formation of an ionic compound.

For example, KI is an ionic compound.

Thus, we can conclude that C_{6}H_{12}O_{6} and HCl are the two substances which are covalent compounds.

Which of the following is a property of an acid
liberstina [14]

Answer:

Explanation: Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. ... Acids have a pH less than 7 ; Bases have a pH greater than 7.

How many moles of carbon dioxide are produced when 23.0 g of C3H2O3 is burned during the
Mars2501 [29]

Moles of Carbon dioxide : 0.75

<h3>Further explanation</h3>

Given

23 g C₃H₈O₃

Required

Moles of Carbon dioxide

Solution

Reaction

2C₃H₈O₃ + 7O₂ → 6CO₂ + 8H₂O

mol C₃H₈O₃ :

= mass : MW

= 23 g : 92,09382 g/mol

= 0.24975

From the equation, mol ratio of C₃H₈O₃ : 3CO₂ = 1 : 3, so mol CO₂ :

= 3/1 x mol C₃H₈O₃

= 3/1 x 0.24975

= 0.74925≈0.750 mol

The following reactions occur at 500K. arrange them in orderof increasing tendency to proceed to completion.
77julia77 [94]

Answer:

B. 3<4<1<2

Explanation:

Upon comparing all four equations, you would find that it is pretty much only the value of Kp that varies.

So we have to understand what Kp is and its relationship with tendency of completion.

Kp is the equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressures. It is a unitless number, although it relates the pressures.

So what is the significance?

If K is a large number, it means that the equilibrium concentration of the products is large. In this case, the reaction as written will proceed to the right (resulting in an increase in the concentration of products).

So what do we now?

We pretty much just have to arrange the equations in order of increasing K values.

Upon doing that, we are left with;

3) 2SO3 <---> 2SO2 +O2 Kp= 1.3x 10-5

4) 2NO2 <---> 2NO +O2 Kp=5.9 x 10-5

1) 2NOCl <---> 2NO +Cl2 Kp=1.7 x 10-2

2) N2O4 <--->2NO2 Kp= 1.5x 103

So the order is given as; 3<4<1<2
