Answer:

18.0 g

Explanation:

M(H2) = 2.0 g/mol

32.0g * 1 mol/2 g= 16 mol H2

M(O2) = 32 g/mol

16.0 g * 1mol/32 g= 0.5 mol O2

                                      2H2 + O2 ---> 2H2O

from reaction              2 mol    1 mol

given                         16 mol     0.5 mol

We see that O2 is a limiting reactant.

                                    2H2 + O2 +-------> 2H2O

from reaction                         1 mol            2 mol

given                                      0.5 mol        x mol

x =(0.5*2)/1= 1 mol H2O

M(H2O)= 18 g/mol

18 g/mol* 1 mol = 18 g H2O

Answer:

0.164541341 g H2

Explanation:

1) Convert grams to moles by dividing by RMM of Magnesium (24.31g).

  2g Mg * (1 mol Mg / 24.31 g Mg) = 0.082270671 mol of Mg

2) Use the balanced equation's ratio of 1 mol Mg: 1 mol H2.

  0.082270671 mol of Mg = 0.082270671 mol of H2

3) Convert the mol of H2 back into grams by multiplying by H2's RMM (2 g).

  0.082270671 mol of H2 * 2 g H2 = 0.164541341 g H2

Answer:

Explanation:

For amount of radiation from a hot body there is Stefan's Boltzman's law which is given below .

E = e σ T⁴

E is amount emitted , e is emissivity , σ is stefan's constant = 5.67 X 10⁻⁸ W / m² . for earth e =.85 approx

E = .85 x 5.67 X 10⁻⁸ x T⁴

604 = .85 x 5.67 X 10⁻⁸ x T⁴

604 = 4.82 x 10⁻⁸ T⁴

T⁴ = 125.31 x 10⁸

T =  3.3457 x 10²

= 334.57K

Temperature in Celsius = 334.57 - 273

= 61.57 Celsius .

Answer:

27 moles of H₂

Explanation:

Equation of reaction:

N₂ + 3H₂ → 2NH₃

From the equation of reaction,

3 moles of H₂ is required to produce 2 moles of NH₃

3 moles H₂ = 2 moles of NH₃

X moles of H₂ = 18 moles of NH₃

X = (3 * 18) / 2

X = 27 moles of H₂

27 moles of H₂ is required to produce 18 moles of NH₃

Answer:

A metal and a nonmetal

Explanation:

Picture NaCl, the most famous example of an ionic compound. Two ions, Na+ (sodium) and Cl- (chlorine) are joined by an ionic bond.

Sodium, the metal, gives up an electron to chlorine.

Chlorine, the nonmetal, accepts an electron from sodium.

That way both have 8 electrons in their outer shell! This is the way ionic bonds function.

According to the law of conservation of mass, there is no net change in the reactants' and products' masses before and after a chemical reaction.

Chemical reaction is defined as a procedure where one or more compounds, known as reactants, are changed into one or more new substances, known as products. When atoms establish or break chemical bonds, chemical reaction take place.

Law of conservation of mass is defined as a chemical reaction requires that the total mass of the reactants and products be equal. Law of conservation of mass also stated that mass is always conserved throughout chemical reactions and cannot be created or removed.

Thus, according to the law of conservation of mass, there is no net change in the reactants' and products' masses before and after a chemical reaction.

Answer:

[H⁺] = 1.0 x 10⁻¹² M.

Explanation:

∵ [H⁺][OH⁻] = 10⁻¹⁴.

[OH⁻] = 1 x 10⁻² mol/L.

∴ [H⁺] =  10⁻¹⁴/[OH⁻] = (10⁻¹⁴)/(1 x 10⁻² mol/L) = 1.0 x 10⁻¹² M.

∵ pH = - log[H⁺] = - log(1.0 x 10⁻¹² M) = 12.0.

∴ The solution is basic, since pH id higher than 7 and also the  [OH⁻] > [H⁺].

Answer:

The limiting reactant is the propane gas, C₃H₈ while the percentage yield is 83.77%

Explanation:

Here we have

Propane gas with molecular formula C₃H₈, molar mass  = 44.1 g/mol combining with O₂ as follows

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Therefore, 1 mole of C₃H₈  combines with 5 moles of O₂ to produce 3 moles CO₂ and 4 moles of H₂O

Mass of propane = 0.1240 kg = 124.0 g

Number of moles of propane = mass of propane/(molar mass of propane)

The number of moles of propane = 124/44.1 = 2.812 moles

The molar mass of CO₂ = 44.01 g/mol

Mass of CO₂ = 0.3110 kg = 311.0 g

Therefore, number of moles of CO₂ = mass of CO₂/(molar mass of CO₂)

The number of moles of CO₂ = 311.0 kg/ 44.01 g/mol = 7.067 moles

Therefore, since 1 mole of propane produces 3 moles of CO₂, 2.812 moles of propane will produce 3 × 2.812 moles or 8.44 moles of CO₂

Therefore;

The limiting reactant is the propane gas, C₃H₈, since the oxygen is in excess

Hence

[tex]The \ percentage \ yield = \frac{Actual \, yield}{Theoretical \, yield} \times 100 = \frac{7.067}{8.44} \times 100 = 83.77 \%[/tex]

The percentage yield = 83.77%.

Light is an electromagnetic wave which travels regardless of whether there is medium. sound is a wave disturbance in medium meaning it must have matter. Also light is much faster then sound.

Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.

The states of matter are the different forms of the matter in which it can exist. They are solids, liquids and gases. Solids are the states of matter in which molecules are very near to each other. They have fixed shape and volume. Liquids is the states of matter in which molecules are a little far from each other. They have different shape and fixed volume. Gas is the states of matter in which molecules are a very far from each other. They have different shape and different volume.

There are two more states of matter which are called as Plasma, Bose Einstein Condensate.

Plasma have highest energy and Bose Einstein Condensate have lowest energy.

Therefore, Solids are the most organized state of matter. States of matter change when energy is added or removed. Gas is the state of matter has the most movement of its particles.

Answer:

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]

Explanation:

Molarity is a unit of concentration that is based on the volume of a solution and represents the number of moles of solutes contained in a liter. The molarity of a solution is calculated by dividing the moles of the solute by the liters of the solution and is expressed in units (moles / liter).

[tex]Molarity=\frac{number of moles of solute}{Volume}[/tex]

You must calculate the number of moles of CuSO₄. So, being:

the molar mass of CuSO₄ is

CuSO₄=63.54 g/mole + 32 g/mole + 4* 16 g/mole= 159.54 g/mole

Then it is possible to apply the following rule of three: if 159.54 g of CuSO₄ are present in 1 mole, 10 g in how many moles are they?

[tex]moles=\frac{10 g*1 mole}{159.54 g}[/tex]

moles= 0.063 moles

Then:

Replacing in the definition of molarity:

[tex]Molarity=\frac{0.063 moles}{0.05 L}[/tex]

Molarity= 1.26 [tex]\frac{ moles}{L}[/tex]

The molarity is 1.26 [tex]\frac{ moles}{L}[/tex]
