What element is found in liver and is needed to prevent anemia or tired blood.

Chemistry
1 answer:
DochEvi [55]3 years ago
3 0


The element found in the liver that helps prevent anemia is iron.

Iron is an essential element for blood production. Close to 70% of the body's iron is found in the red blood cells. In the red blood cells it is a vital ingredient of hemoglobin, the red pigment that gives blood its red color. In the muscle cells, iron is found as myoglobin.

Iron is stored mostly in the liver as ferritin or hemosiderin.

When iron stores are finished or exhausted, the condition is called iron depletion. When the shortage of iron is severe, it results in a condition known as iron deficiency anemia whereby the red blood cells do not have enough hemoglobin.

815 yd to km (need 3 sig fig)
SpyIntel [72]

<u>Answer:</u> The correct answer is 0.745 km

<u>Explanation:</u>

We are given:

A numerical value of 815 yards

To convert this into kilometers, we use the conversion factor:

1 km = 1093.6 yards

Converting the given value into kilometers, we get:

\Rightarrow 815yd\times \frac{1km}{1093.6yd}=0.745km

Hence, the correct answer is 0.745 km

200g of solution of magnesium
diamong [38]

The mass of reacted magnesium chloride is 23.75g, percent by mass of solution magnesium chloride is 90.9%.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

n = W/M, where

  • W = given mass
  • M = molar mass

Moles of MgCl₂ = 200g / 95g/mol = 2.1mol

Moles of NaOH = 20g / 0.5mol

Given chemical reaction is:

MgCl₂ + 2NaOH → 2NaCl + Mg(OH)₂

From the stoichiometry of the reaction it is clear that

  • 1 mole of MgCl₂ = reacts with 2 moles of NaOH
  • 0.5 mole of NaOH = reacts with (1/2)(0.5)=0.25 moles of MgCl₂

Mass of reacted MgCl₂ = (0.25mol)(95g/mol) = 23.75g

Percent by mass of MgCl₂ in the given solution mixture will be calculated as:

  • % by mass = (Mass of MgCl₂ / Total mass of mixture) × 100%
  • Percent by mass of MgCl₂ = (200/200+20)×100% = 90.0&

In the above reaction we obtain NaCl as a solid, and MgCl₂ is the limiting reagent in it, from which 2 moles of NaCl is produced means

  • 0.25 moles of MgCl₂ = produces 0.5 moles of NaCl

Mass of NaCl = (0.5mol)(58.5g/mol) = 29.25g

Hence, mass of reacted MgCl₂ is 23.75g, percent by mass of solution magnesium chloride is 90.9% and mass of the obtained solid is 29.25g.

Pure titanium metal is produced by reaction titanium(IV) chloride with magnesium metal. The equation for the reaction is: TiCl4(
qaws [65]

Answer:

The answer to your question is 1.013 Kg

Explanation:

                     TiCl₄  +  2Mg   ⇒     2MgCl₂   +   Ti

mass of Mg = ?

mass of Ti = 1 kg

Process

1.- Calculate the molar mass of Magnesium and titanium (IV)

    Mg = 24.3 g x 2 = 48.6 g

    Ti = 48 g

2.- Write a proportion (rule of three)

                         48.6 g of Mg -------------  48 g of Ti

                           x                   -------------  1000 g of Ti

                           x = (1000 x 48.6) / 48

3.- Result

                 mass of Magnesium = 1012.5g

                                                    = 1.013 kg
