Explanation:

The problem is about Conservation of Energy, between Potential Energy and Kinetic energy changes.

Given is friction-less roller coaster. it is also assumed that there is no loss of energy due to air friction.

And so regardless of what path the ball takes, the work done by gravity doesn't depend on the path, it only depends upon the height through which it falls.

3. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.

Answer:

Mg2+

Explanation:

The most reactive ions from the given choices is the magnesium ion. This is because it is higher in the activity series of metals.

Zinc ion is below this specie in the activity series.

As a rule, ions above another on the activity series are generally more reactive than those below.

From any solution, magnesium ion will displace the zinc ion in such process.

The position of metallic ions determines their reactivity.

Explanation:

Note: Molar masses of elements can be found online or in the periodic table.

Moles of Magnesium

= 3.60g / (24.3g/mol) = 0.148mol.

Moles of Chlorine

= 10.65g / (35.45g/mol) = 0.300mol.

Mole ratio of Magnesium to Chlorine

= 0.148mol : 0.300mol = 1 : 2.

Hence we have the empirical formula MgCl2.

Moles of Lithium

= 9.1g / (6.94g/mol) = 1.311mol.

Moles of Oxygen

= 10.4g / (16g/mol) = 0.650mol.

Moles ratio of Lithium to Oxygen

= 1.311mol : 0.650mol = 2 : 1.

Hence we have the empirical formula Li2O.

Answer:

2.7 moles of Fe₂O₃ is the maximum amount that can be produced. Iron is the limiting reactant.

Explanation:

The balanced reaction is:

4 Fe + 3 O₂ → 2 Fe₂O₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

You can use a simple rule of three as follows: if by stoichiometry 4 moles of Fe reacts with 3 moles of O₂, how much moles of Fe will be needed if 4.7 moles of O₂ react?

[tex]moles of Fe =\frac{4. moles of Fe*4.7 moles of O_{2}}{3 moles of O_{2} }[/tex]

moles of O₂= 6.27

But 6.27 moles of Fe are not available, 5.4 moles are available. Since you have less moles than you need to react with 4.7 moles of O₂, iron Fe will be the limiting reagent.

So you can use a simple rule of three as follows: if by stoichiometry 4 moles of Fe produce 2 moles of Fe₂O₃, how many moles of Fe₂O₃ will be produced if 5.4 moles of Fe react?

[tex]moles of Fe_{2}O_{3}=\frac{5.4 moles of Fe*2 moles of Fe_{2} O_{3} }{4 moles of Fe}[/tex]

moles of Fe₂O₃= 2.7 moles

Then:

2.7 moles of Fe₂O₃ is the maximum amount that can be produced. Iron is the limiting reactant.

Answer:

Magnesium

0.003mole

Explanation:

The problem here entails we find the metal in the carbonate.

 For group 2 member, let the metal  = X;

 The carbonate is XCO₃;

 If we sum the atomic mass of the elements in the metal carbonate, we should arrive at 84g/mol

 Atomic mass of C = 12g/mol

                            O  = 16g/mol

 Atomic mass of X + 12 + 3(16)  = 84

  Atomic mass of X  = 84 - 60  = 24g/mol

The element with atomic mass of 24g is Magnesium

B.

Number of moles in 0.3g of CaCO₃:

     Molar mass of CaCO₃   = 40 + 12 + 3(16)  = 100g/mol

 Number of moles = [tex]\frac{mass}{molar mass}[/tex]  

 Number of moles  = [tex]\frac{0.3}{100}[/tex]   = 0.003mole

Answer:

High temperature and intense pressure may transform an igneous rock into a metamorphic rock with banded layers.  

Explanation:

A metamorphic rock is formed under high temperature and intense pressure may transform an igneous rock into a metamorphic rock with banded layers.

An igneous rock is often formed when molten magma erupts from the earth's crust. The molten magma is usually very hot but cools off with time to form a solid mass.

This rock that was first formed eventually gets transformed in the course of time as it is acted upon by high temperature and intense pressure which gradually transforms the igneous rock into a metamorphic rock with banded layers.

Answer:

1) 3 2) 2 3) 1 4) 3

Explanation:

so on the reactant side (left), there is 2 H, 1 CO3, and 1 Fe. On the product side (right) there is 2 Fe, 3 CO3, and 2 H2. So to start I added a 3 in the first blank to make CO3 equal on both sides. In doing this, there is not 2 H, there is now 6 so I added a 3 in the 4th blank. Currently, H and CO3 are equal on both sides but not Fe. So I added a 2 in the 2nd blank. I didn't add anything in the 3rd blank so it is an understood 1.

The balanced equation

3H₂CO₃ + 2Fe → Fe₂(CO₃)₃ + 3H₂

Given

Reaction

H₂CO₃ + Fe → Fe₂(CO₃)₃ + H₂

Required

Coefficient of the reaction

Solution

aH₂CO₃ + bFe → Fe₂(CO₃)₃ + cH₂

Prioritize balancing the elements that form the most complex compounds

Fe, left = b, right = 2⇒b=2

C, left = a, right = 3⇒a=3

H, left = 2a, right = 2c⇒2a=2c⇒2.3=2c⇒6=2c⇒c=3

The equation becomes :

3H₂CO₃ + 2Fe → Fe₂(CO₃)₃ + 3H₂

Explanation:

3Mg(s) + N2(g) = Mg3N2(s)

First check that the equation is balanced. In this case, it is.

Assuming that magnesium is the limiting reactant:

       We find that the atomic mass of magnesium is approximately

       24.3g, so the molecular weight is just 24.3g\mol

    2. Next we need the mole to mole ratio. As there are 3

        magnesiums for 1 magnesium nitride (shown by the coefficients), the                    

        mole to mole ratio is 1 mol Mg3N2\3 mol Mg.

    3. We need the amount of the substance, in grams. Since you have not    

        stated it in the question, I'll just do 10g AS AN EXAMPLE. Note that    

       depending on the amount, the LIMITING REAGENT MAY DIFFER.

   4.  Finally, we need the molecular weight of Mg3N2, which we can easily    

        calculate to be around 100.9\mol.

   5.  Putting this all together, we have 10gMg⋅ (mol Mg\24.3gMg)

        (1mol Mg3N2\ 3mol Mg) (100.9g Mg3N2\mol Mg3N2)

        the units will cancel to leave gMg3N2 (grams of magnesium nitride):

       10gMg ⋅ (mol Mg\24.3gMg) (1mol Mg3N2\3mol Mg)

       (100.9g Mg3N2\mol Mg3N2)

Doing the calculation yields approximately 13.84g.

Assuming that nitrogen is the limiting reactant:

Similarly, following the above steps but with 10g of nitrogen yields 36.04g

In conclusion, as we produce less amount of Mg3N2 when we assumed that Mg was the limiting reagent, magnesium is the limiting reagent and nitrogen is the excess.

Note: This is in THIS CASE, where we have 10g of both. The answer may vary depending on the amount of each substance.

Answer:

  1.46×10^25 molecules

Explanation:

Each mole of N₂ reacts with 3 moles of Mg to form 1 mole of Mg₃N₂. That is, the number of moles of product is equal to the number of moles of nitrogen gas when excess magnesium is present.

There are 6.022×10²³ molecules in each mole of a substance, so the number of molecules of Mg₃N₂ is

  (24.3 mol)(6.022×10²³ molecules/mol) = 1.46×10²⁵ molecules
