why would you expect to see similar rocks and rock structures on two land masses that were connected at one time?

tangare [24]

If they were connected at one time than you would expect to find similar rock structures because they eroded, weathered, and we’re formed most likely at the same time out of the same material. So basically since they were near each other they were under the same or similar conditions.

How many moles of carbon are in 7.00 x 1023 atoms of carbon?

Andru [333]

Answer:

<h2>1.16 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{7 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{7}{6.02} \\ = 1.162790....$

We have the final answer as

<h3>1.16 moles</h3>

Hope this helps you

castortr0y [4]

Answer:

Milk, cream, milk solids, sugars, modifying agents and flavourings are blended together in stainless steel vats.

A saturated solution of pbcl2 is found to contain 2.88 x 10-2 m chloride ions. what is the correct value of the solubility produ

bazaltina [42]

The solubility equilibrium of PbCl $_{2}$ :

$PbCl_{2}(aq) Pb^{2+}(aq) + 2 Cl^{-}(aq)$

$K_{sp}=[Pb^{2+}][Cl^{-}]^{2}$

$[Cl^{-}] = 2.88 * 10^{-2} M$

$[Pb^{2+}]=\frac{[Cl^{-}]}{2} = \frac{2.88 * 10^{-2}}{2}=1.44 *10^{-2}$

$K_{sp}=[Pb^{2+}][Cl^{-}]^{2}$

= $(1.44 * 10^{-2})(2.88*10^{-2})^{2}$

= $1.19 * 10^{-5}$

So, the corrected solubility product will be $1.19 * 10^{-5}$
