Answer:

No, Mercury can actually cause poisoning. That is why other metals, such as Alkaline metals, are used in making batteries

Answer:

Mercury can be found in most common household batteries but will most likely be discontinued in the future.

Explanation:

Zinc air, alkaline, and silver oxide button cell all include mercury but only in SMALL amounts. Chances of this mercury leaking are very unlikely and does not pose a large danger to people. In present day, most batteries are turning away from using mercury so its most likely mercury batteries will not be found in the future.

positive ions are smaller than the ions from which they are formed but negative ions are larger than the is from which they are
Vadim26 [7]
Positive ions are atoms that have lost an electron from its outtermost shell. It is positive because electrons are negative and the loss of something negative makes it a bit more positive.
A negative ion is larger than its original atom because it's gained an electron.

The more electrons an atomic has on its electron cloud, the bigger the atom.

Hopefully I didn't confuse you, good luck. ♡

Consider the hypothetical reaction A(g)←→2B(g). A flask is charged with 0.77 atm of pure A, after which it is allowed to reach e
ankoles [38]

<u>Answer:</u>

<u>For A:</u> The total pressure in the flask at equilibrium is 1.19 atm

<u>For B:</u> The value of K_p for the given equation is 2.016

<u>Explanation:</u>

We are given:

Initial partial pressure of A = 0.77 atm

Equilibrium partial pressure of A = 0.35 atm

  • <u>For A:</u>

For the given chemical equation:

                  A(g)\rightleftharpoons 2B(g)

<u>Initial:</u>         0.77

<u>At eqllm:</u>   0.77-x     2x

Evaluating the value of 'x'

\Rightarrow (0.77-x)=0.35\\\\x=0.42

Equilibrium partial pressure of B = 2x = (2 × 0.42) = 0.84 atm

Total pressure in the flask at equilibrium = p^A_{eq}+p^b_{eq}=[0.35+0.84]atm=1.19atm

Hence, the total pressure in the flask at equilibrium is 1.19 atm

  • <u>For B:</u>

The expression of K_p for given equation follows:

K_p=\frac{(p_B)^2}{p_A}

Putting values in above expression, we get:

K_p=\frac{(0.84)^2}{0.35}\\\\K_p=2.016

Hence, the value of K_p for the given equation is 2.016
