Answer:

See explanation

Explanation:

An ionic bond involves the transfer of electrons from one atom to another. Typically, ionic bond occurs between a metal and a non metal such as between Na and Cl.

A polar covalent bond occurs between  two elements having a significant difference in elctronegativity. As a result of this, the shared electron pair is closer to the more electronegative atom thereby making the molecule polar.

A covalent bond involves the sharing of electrons between two atoms that are very close in electronegativity values.  The shared electron pair is located at an equidistant position from the nucleus of the both bonding atoms.

For MgCl2, the electronegativity difference is 3.0 - 1.2 = 1.8, the bond is ionic

For F2, the electronegativity difference is 4.0 -4.0 = 0, it is a pure covalent bond.

For NaCl, the electronegativity difference is 3.0 - 0.9 = 2.1, the bond is ionic

guapka [62]

Answer:

A

Explanation:

What the equation is tell you is that for every 3 mols of NO2 you get 2 mol of HNO3

3 mol NO2 / 2 mol HNO2 ===> 300.00 mol NO2 / x   Cross multiply

3x = 2 * 300

3x = 600                 Divide by 3

3x/3 = 600/3           Do the division

x = 200.00

What mass of butane in grams is necessary to produce 1.5×103 kJ1.5×103 kJ of heat? What mass of CO2CO2 is produced? Assume the r
saul85 [17]

32.8 g of Butane is required and 99.3 g of CO₂ is produced

<u>Explanation:</u>

The above mentioned reaction can be written as,

C₄H₁₀(g) + 13 O₂(g) → 4CO₂(g) + 5 H₂O(g)     where ΔH (rxn)= -2658 kJ

It is given that 1.5 × 10³ kJ of energy is produced, the original reaction says that 2658 kJ of heat is produced, which means that less than one mole of butane is used in the reaction.

That is

$\frac{1500}{2658}=0.564 \text { moles }    of butane reacted

Now this moles is converted into mass by multiplying it with its molar mass  = 0.564 mol × 58.122 g / mol

                     = 32.8 g of butane.

Mass of CO₂ produced = 0.564 ×44.01 g /mol × 4 mol

                                        = 99.3 g of CO₂

Thus 32.8 g of Butane is required and 99.3 g of CO₂ is produced

What is the overall charge of a Aluminum atom that loses 3 electrons​
Rudik [331]
It’s charge was neutral due to the equal number of protons and electrons. when it becomes an ion it loses 3 electrons leaving behind only 10. the answer is 10. the equation is +13 +(-10)=+3
