Answer: Air masses





Explanation: An air mass is a large body of air that has about the same conditions throughout. For example, an air mass might have cold dry air. Another air mass might have warm moist air. The characteristics of an air mass depend on where the air mass formed. The air must stay over that location long enough to pick up those characteristics.

Why is the? The second ionization energy of sodium is about three times greater than the second ionization energy of magnesium
Scorpion4ik [409]

Answer:

~Na+1 is already in the preferred form. Because of this, the second ionization energy of sodium is higher than normal. Mg+1 loses an electron to form s2 p6 .

How many moles of atoms are in each elemental sample?
Vlada [557]

Answer:

Moles = mass(m) / Molar mass (M)

A. 1.24g of Zn

m = 1.24g

M = 65.4 g/mol

moles of Zn = 1.24g/ 65.4g/mol

= 0.01896mol

B. 28.1 g Ar

m = 28.1g

M(Ar) = 39.9g/mol

moles of Ar = 28.1g/39.9g/mol

= 0.7043 mol

C. 84.0 g Ta

m = 84.0g

M(Ta) = 181g/mol

moles of Ta = 84.0g/181g/mol

= 0.4641 mol

D. 2.29x10^-2 g Li

m = 2.29x10^-2 g

M(Li) = 6.9g/mol

moles of Li = 2.29x10^-2 g / 6.9g/mol

= 0.0033 mol

Hope this helps

How many grams of N2 can be produced when 6.50 g of O2<br> reacts?
Olenka [21]

Answer:

3.79 g of N2.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

4NH3 + 3O2 → 2N2 + 6H2O

Next, we shall determine the mass of O2 that reacted and the mass of N2 produced from the balanced equation.

This is illustrated below:

Molar mass of O2 = 16x2 = 32 g/mol

Mass of O2 from the balanced equation = 3 x 32 = 96 g

Molar mass of N2 = 2x14 = 28 g/mol

Mass of N2 from the balanced equation = 2 x 28 = 56 g

Summary:

From the balanced equation above,

96 g of O2 reacted to produce 56 g of N2.

Finally, we shall determine the mass of N2 produced by reacting 6.50 g of O2.

This can be obtained as follow:

From the balanced equation above,

96 g of O2 reacted to produce 56 g of N2.

Therefore, 6.50 g of O2 will react to produce = (6.50 x 56)/96 = 3.79 g of N2.

Therefore, 3.79 g of N2 were obtained from the reaction..
