Answer:

Ionic Bond

Explanation:

The atom with the higher electronegativity wants to fill its valence electron shell (meaning it wants 8 electrons in this shell). The atom with lower electronegativity will want to empty <em>or donate </em>an electron so that it can have an empty valence shell.

Butane (C4 H10(g), mc031-1.jpgHf = –125.6 kJ/mol) reacts with oxygen to produce carbon dioxide (CO2 , mc031-2.jpgHf = –393.5 kJ/
ankoles [38]

The balanced chemical equation for the combustion of butane is:

2C_{4}H_{10}(g) +13 O_{2}(g)-->8CO_{2}(g)+10H_{2}O(g)

ΔH_{reaction}^{0} = Σn_{products}ΔH_{f}^{0}_{(products)}-Σn_{reactants}ΔH_{f}^{0}_{(reactants)}

                         = [{8*(-393.5kJ/mol)}+{10*(-241.82kJ/mol)}]-[{2*(-125.6kJ/mol)}+13*(0 kJ/mol)}]=[-3148kJ/mol+(-2418.2kJ/mol)]-[(-251.2kJ/mol)+0]

                      = -5315 kJ/mol

Calculating the enthalpy of combustion per mole of butane:

1mol C_{4}H_{10}*( \frac{-5315kJ}{2mol C_{4}H_{10} })=-2657.5 \frac{kJ}{molC_{4}H_{10}}

Therefore the heat of combustion per one mole butane is -2657.5 kJ/mol

Correct answer: -2657.5 kJ/mol

Observe the reaction between N2 and H2 to make NH3.
GarryVolchara [31]

Answer: , 4 molecules of ammonia, NH3(g) is produced; 2 molecules of ammonia, NH3(g) is produced respectively

Explanation:

The balanced equation is stated below N2(g) + 3H2(g) → 2NH3(g)

1 mole of N2(g) reacts with 3 moles of H2(g) to yield 2 moles of NH3(g)

1) If 2 molecules of N2 react, then the balanced equation will be

2N2(g) + 6H2(g) → 4NH3(g)

Thus, 4 molecules of ammonia, NH3(g) is produced

2) If 3 molecules of H2 react, then the balanced equation will be

N2(g) + 3H2(g) → 2NH3(g)

Thus, 2 molecules of ammonia, NH3(g) is produced

25) If an object’s density is greater than 1.00 g/mL, it will ______________ in water.
NeTakaya

Answer:

1- Option A = Sink

2- Option B = Float

Explanation:

1- If an object’s density is greater than 1.00 g/mL, it will sink in water.

For example, the density of aluminum is 2.7g/cm³. That is why it will sink in water.

2- If an object’s density is less than 1.00 g/mL, it will float in water.

For example, the density of oak is 0.7 g/cm³. That is why oak will float in water.

3-  Given data:

Mass, m = 50 g  

Volume, v = 10 cm3 ( 1ml = 1cm3)

Formula of density :          

Density = mass/ volume

          d = m/v

          d = 50g/10cm3

          d = 5 g/cm3
