How manymoles of each ion are present in 175 mL of 0.147 M Fe2(SO4)3?
lilavasa [31]

Answer: 0.0257 moles of Fe^{3+}  and 0.0257 moles of SO_4^{2-}

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

moles of  Fe_2(SO_4)_3=Molarity\times {\text {Volume in L}}=0.147\times 0.175L=0.0257moles

The balanced reaction for dissociation will be:

Fe_2(SO_4)_3\rightarrow Fe^{3+}+SO_4^{2-}

According to stoichiometry:  

1 mole of Fe_2(SO_4)_3 gives 1 mole of Fe^{3+}  and 1 mole of SO_4^{2-}

Thus there will be 0.0257 moles of Fe^{3+}  and 0.0257 moles of SO_4^{2-}

The density of copper is 8.92 g/mL. The mass of a piece of copper that has a volume of 10.3 mL is
m_a_m_a [10]

Answer:

The answer is

<h2>91.9 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of copper = 10.3 mL

density = 8.92 g/mL

The mass is

mass = 8.92 × 10.3 = 91.876

We have the final answer as

<h3>91.9 g</h3>

Hope this helps you

. Blood should NOT be stored in which way? As a scraping Dried on a swab In an airtight container Dried on the object
notsponge [240]

Blood should NOT be stored in an airtight container

<h3>Explanation:</h3>

We can store blood by dried it on a swab. To collect the dried blood, we should moisten a sterile cotton swab using distilled water or tap water, then shake the swab to remove excess water. Gently swab the stain with the moistened swab tip until the swab thoroughly absorbs the blood.

We can store blood also in the dried blood stains and as a scraping. The fresh collected blood, dried blood stains, wet blood stains are contained the DNA.

Airtight containers are the plastic used to make the durable containers and it is free from BPA and has been graded to be safe to be used with food supplies. ​The lid of this container has an innovative airtight mechanism which helps to maintain the airtight environment inside the container.

According to book "Criminal Investigation" By Ronald F. Becker on page 114, the airtight containers can cause condensation of moisture within the container and result in bacteria that can destroy, alter or contaminate the blood.

Blood components should be stored at temperatures storage in accordance with the requirements listed. Failure to follow correct storage requirements result in decreased transfusion efficacy
