When magnesium reacts with sulfuric acid the products are magnesium sulfate and hydrogen. If there are 15 grams of magnesium at the start of the reaction, how much magnesium will be present in the magnesium sulfate

Answers

Answer: 15 grams of magnesium will be present in the magnesium sulfate

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical reaction is:

[tex]Mg+H_2SO_4\rightarrow MgSO_4+H_2[/tex]

As the mass remains conserved at the end of the reaction, there will be 15 grams of Magnesium in magnesium sulphate.

1. 0.488M
2. 7.67mol
3. 7.67M
4. 0.000767M

Answers

Answer:

7.67

Explanation:

According to molar concentration, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution of values in the given formula gives, molarity= 22.41/58.44×1/0.05=7.67 M.

Thus, the  molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.

If 3.22 g of precipitate are recovered from the reaction of limewater (Ca(OH),) with carbon dioxide to produce
water and calcium carbonate, what is the percent yield if 20.0 g of carbon dioxide was mixed with the
limewater?
the correct answer is 7.1% but i don't understand what they did

Answers

Answer:

Percent yield = 7.1%

Explanation:

The general reaction of the problem is:

Ca(OH)₂ + CO₂ → H₂O + CaCO₃

To solve this question we need to find theoretical yield using the amount of carbon dioxide added because:

Percent yield = Actual yield (3.22g) / Theoretical yield * 100

Theoretical yield is the maximum amount of product that could be obtained. To find it we need to convert the mass of CO₂ to moles. The moles of CO₂ = Moles of CaCO₃:

Moles CO₂ -Molar mass: 44.01g/mol):

20.0g * (1mol / 44.01g) = 0.454 moles CO₂ = Moles of CaCO₃ produced

Mass CaCO₃ = Theoretical yield -Molar mass: 100.09g/mol-:

0.454 moles * (100.09g / mol) = 45.5g of CaCO₃ = Theoretical yield.

Replacing:

Percent yield = 3.22g / 45.5g * 100

Percent yield = 7.1%

Answers

Answer:

1.) Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer.

2.) Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.

Explanation:

I got it right on the test.

Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer and Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.

What is energy transfer?

When energy of any body travels from the one body to the another body, then transfer of energy takes place.

In the oceans, winds transfer their energy to the ocean or to the sea by the interaction with the surface water. When on the surface of ocean or sea up and down movement of water occurs then the interaction of that water with wind takes place and transfer of energy from wind to sea happen. More roughness or more height of the water on the surface of sea observed ten more transfer of energy from wind to sea occur.

Hence, option (1) & (2) is correct i.e. wind moving over a relatively flat water surface reduces energy transfer and Larger waves increasing the transfer of the wind's energy to the water.

how much heat is released as 5.00G of PB cool from 75.0° C to 25.0° C

Answers

Answer:

32.25 J

Explanation:

Heat, H = ?

Mass, m = 5g = 5 / 1000 = 0.005 Kg

Initial Temperature = 75.0° C

Final Temperature = 25.0° C

Temperature change, ΔT = Final - Initial = 50° C

Specific heat capacity of lead, C = 129 (J/kg°C)

The relationship between these quantities is given by the equation

H = mCΔT

H = 0.005 * 129 * 50

H = 32.25 J

Seawater is a good source of magnesium. Magnesium is dissolved in the seawater as Mg²⁺. SUGGEST a substance that could be used to precipitate magnesium out of the water. Write a BALANCED CHEMICAL EQUATION and IDENTIFY THE REACTION TYPE to support your thinking

Answers

Answer:

SO₄⁻² (aq)  +  Mg²⁺ (aq)  ⇄  MgSO₄ (s) ↓

Precipitation reaction

Explanation:

Mg²⁻ is one of the metals at group 2 in the Perodic Table. This group is called, the alkaline earth metals.

To make precipitate the Mg²⁺ we can use a salt of sulfate, either flouride or phosphate. Those are three salts that can precipitate this metal.

We use sodium as cathion so, first of all we dissociate them:

Na₂SO₄ (aq) →  2Na⁺  (aq)  +  SO₄⁻² (aq)

NaF (aq) →  Na⁺ (aq) +  F⁻ (aq)

Na₃PO₄ (aq) →  3Na⁺ (aq)  +  PO₄⁻³ (aq)

In all cases, the reaction is of the precipitation type and is conditioned by the Kps, the solubility product constant. Let's bond the anions with Mg²⁺.

SO₄⁻² (aq)  +  Mg²⁺ (aq)  ⇄  MgSO₄ (s) ↓    Kps

2F⁻ (aq)  +  Mg²⁺ (aq)  ⇄   MgF₂ (s) ↓      Kps

2PO₄⁻³ (aq)  +  3Mg²⁺ (aq)  ⇄  Mg₃PO₄ (s) ↓   Kps

Answers

Answer: A. dipole

Explanation:

Dipole can be defined as the separation of the equal and opposite charges present in the molecule via ionic bonding. The water molecule comprising of two molecules of hydrogen being positively charged and one molecule of oxygen being negatively charged are connected via ionic bonding thus water molecule is an example of dipole molecule. There is unequal distribution of the electrical density throughout the molecule.

The polar molecule results in a dipole when equal but opposite charges are present in two regions.

Dipole:  

Dipole arises when a molecule have opposite and equal charge in the ends.

For example - water molecule

In water molecule Oxygen is negatively charged and hydrogen have low electronegativity, this difference in electronegativities arise dipole in molecule.

Therefore, the polar molecule results in a dipole when equal but opposite charges are present in two regions.

in reaction 3Fe+2O2=Fe3O4 if I add 20g of Fe to my solution how many moles of Fe3O4 will produce???

Answers

Answer:

0.119 moles

Explanation:

molar mass of Fe = 55.845g

to find moles = mass/ molar mass

so moles of Fe = 20/55.845

= 0.358 moles

for the equation you are given

for every three Fe, it produces 1 Fe3O4 , meaning the ratio is 3:1

if you have 0.358 moles of Fe, that means the number of moles of Fe3O4  will equal to one third of that,

thus

moles of Fe3O4 = 1/3 x 0.358 = 0.119
