Answer:

option B = lower left of the periodic table

Explanation:

The most reactive metals are located at the bottom left corner of periodic table. These metals are reactive in the sense that they can react with water very easily.

Examples include lithium, sodium potassium. As we move down the group in this column metallic character increase. Their atomic radius also increases and electron can easily donated. which means metals became more reactive.

These metals can also react very easily with O2 in atmosphere that's way these are stored in inert atmosphere. The most reactive metal in periodic table is francium.

If 16.5g of c6h14o2 are reacted vwith .499 mol of o2. How many moles of co2 should be produced

Fed [463]

Answer:

moles of carbon dioxide produced are 410.9 mol.

Explanation:

Given data:

Mass of C₆H₁₄O₂ = 16.5 g

Moles of O₂ = 499 mol

Moles of CO₂ = ?

First of all we will write the balance chemical equation.

2C₆H₁₄O₂ + 17O₂ → 14CO₂ + 12H₂O

moles of C₆H₁₄O₂ = mass × molar mass

moles of C₆H₁₄O₂ = 16.5 g × 118 g/mol

moles of C₆H₁₄O₂ = 1947 mol

Now we compare the moles of CO₂ with moles of O₂ and C₆H₁₄O₂ from balance chemical equation.

O₂ : CO₂

17 : 14

499 : 14/17× 499 = 410.9 moles

C₆H₁₄O₂ : CO₂

2 : 14

1947 : 14/2× 1947 = 13629 moles

Oxygen will be limiting reactant so moles of carbon dioxide produced are 410.9 mol.

Which alkane would have a higher boiling point?a)ethaneb)pentanec)heptane

Whitepunk [10]

Answer:

The correct answer is option c.

Explanation:

Alkanes with higher molecular mass has higher boiling point.

Thisis because when the molar mass of the alkanes increases the the surface area increases with which van der Waals forces between the molecules of alkane also increase which increases the association of the molecules of with each other which results in increase in boiling point is observed.

The increasing order of the molar mass of the given alkanes;

$C_2H_6$

So out of ethane, pentane and heptane . Heptane has highest molecular mass with higher boiling point value. Where as ethane have the lowest value of boiling point.
