Answer:

None of the above.

Explanation:

a, c, and d are correct.

a. In a reaction at equilibrium, the forward and reverse reactions are occurring at the same rate.

c. If the position of equilibrium lies to the right, the forward reaction has "gone further" than the reverse reaction.

d. Even if the position of equilibrium is far to the right, the balanced equation for the equilibrium has equal numbers on each side of the equation. For example, in the equilibrium reaction 2H₂ + O₂ ⇌ 2H₂O, the position of equilibrium is far to the right but there are equal atoms on each side of the reaction.

b. is wrong. It is exceptionally rare for reactants and products to have the same concentrations at equilibrium.

Write the complete chemical formula for the unknown compound.

Zinaida [17]

The complete chemical formula for the unknown compound will be $C_2H_6$

<h3>Chemical formula</h3>

The chemical formula of the compound is $C_2H_x$ and x is supposed to be a whole number.

In the analysis, C = 2.22 moles and H = 6.7 moles

Dividing both by the smallest: C = 1 and H = 3

Thus, the empirical formula of the compound will be $CH_3$

But since the compound is $C_2H_x$ , it means both C and H are multiplied by 2.

The chemical formula will, therefore, be $C_2H_6$

A piece of glass has a temperature of 83˚C. Liquid that has a temperature of 43˚C is poured over the glass, completely covering

Lerok [7]

Answer: The specific heat of the liquid is $2520J/kg^0C$

Explanation:

$heat_{absorbed}=heat_{released}$

As we know that,

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

.................(1)

where,

q = heat absorbed or released

= mass of glass = x kg

= mass of liquid = x kg

= final temperature =

$T_1$ = temperature of glass = $83^oC$

$T_2$ = temperature of liquid = $43^oC$

$c_1$ = specific heat of glass = $840J/kg^0C$

$c_2$ = specific heat of liquid= ?

Now put all the given values in equation (1), we get

$-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)$

$c_2=2520J/kg^0C$

Therefore, the specific heat of the liquid is $2520J/kg^0C$

How does a person's senses help identify the properties of a material

Marysya12 [62]

Touch can sense the texture, and you can see what color it is, but if your talking about chemical properties, I'd say smell, color, and heat can identify some chemicals.
