At 900 ∘c,kc=0. 0108 for the reaction caco3(s)←→cao(s)+co2(g) a mixture of caco3, cao, and co2 is placed in a 10. 0-l vessel at

The concentration of CaCO3 increases in all cases because Q> K.

<h3>What is equilibrium?</h3>

A chemical reaction is said to have attained equilibrium when the rate of forward reaction is equal to the rate of reverse reaction. We are told that the Kc of the reaction is 0. 0108.

In the first case:

CaCO3 - 15.0 g/100g/mol/10 L = 0.015 M

CaO - 15.0 g/56 g/mol/10 L = 0.027 M

CO2 - 4.25 g/44 g/mol / 10 L = 0.0096 M

Q = [0.027] [0.0096]/0.015

Q = 0.017

Since Q > K, the concentration of CaCO3 increases

In the second case;

CaCO3 - 2.5 g/100g/mol/10 L =0.0025 M

CaO - 25.0 g/56 g/mol/10 L = 0.045 M

CO2 - 5.66 g/44 g/mol / 10 L = 0.013 M

Q = [0.045 ] [ 0.013]/[0.0025 ]

Q = 0.23

Q > K the concentration of CaCO3 increases

In the third case;

CaCO3 - 30.5 g/100g/mol/10 L =0.031 M

CaO - 25.5 g/56 g/mol/10 L =0.046 M

CO2 - 6.48 g//44 g/mol / 10 L = 0.015 M

Q = [0.046] [ 0.015]/[0.031]

Q = 0.022

Q> K hence the concentration of CaCO3 increases

Missing parts: At 900oC, Kc = 0.0108 for the reaction: CaCO3(s) <===> CaO(s) + CO2(g) A mixture of CaCO3, CaO, and CO2 is placed in a 10.0 Liter vessel at 900oC. For the following mixtures, will the amount of CaCO3 increase, decrease, or remain the same as the system approaches equilibrium?

Choice A is the best answer. Throughout the passage, Woolf advocates for
more women to engage with existing institutions by joining the workforce:
"We too can leave the house, can mount those steps [to an office], pass in
and out of those doors, . . . make money, administer justice . . ." (lines 30-32).
Woolf tells educated women that they are at a "moment of transition" (line 51)
where they must consider their future role in the workforce.

Choice B is incorrect because even though Woolf mentions women's traditional
roles (lines 68-69: "while they stirred the pot, while they rocked the
cradle"), she does not suggest that women will have to give up these traditional
roles to gain positions of influence.

Choice C is incorrect because though
Woolf wonders how "the procession of the sons of educated men" impacts
women's roles, she does not argue that this male-dominated society has had
grave and continuing effects.

Choice D is incorrect because while Woolf suggests
educated women can hold positions currently held by men, she does not
suggest that women's entry into positions of power will change those positions.

rock x is released from rest at the top of a cliff that is on earth. a short time later, rock y is released from rest from the s

Sergeu [11.5K]

The velocity of an object in free fall increases downwards with time

Please find attached the correct graph showing velocity as a function time, with the positive direction to be upwards.

Reason:

The known parameters are;

Location where the rocks are released; Earth

The time at which rock Y is released = A few seconds after rock X is released.

Required:

To select the graph that shows the vertical velocity of rock, <em>x</em>, as a function of time.

Solution:

Let <em>t </em>represent the time after which rock x are released, with the positive direction being upwards, we have;

The equation for the velocity of x is v = -9.81·t

With the above equation, the graph of the vertical velocity of rock x is plotted with MS Excel.

Did the egyptains treat cats like gods and if they did why?

attashe74 [19]

Yes they did. You could even get the death penalty if you killed a cat.
They treated them so well because they protected their grains and other foods from rodents
Cats also helped protect their ancient libraries.
