Answer:

Mass = 51 g

Explanation:

Given data:

Mass of ammonia formed = ?

Number of moles of hydrogen = 4.50 mol

Solution:

Chemical equation:

N₂ + 3H₂ → 2NH₃

Now we will compare the moles of hydrogen and ammonia.

H₂ : NH₃

3 : 2

4.50 : 2/3×4.50 = 3 mol

Mass of ammonia formed:

Mass = number of moles × molar mass

Mass = 3 mol × 17 g/mol

Mass = 51 g

How does the electro negativity difference between atoms determine the type of bond they will form

siniylev [52]

The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic.

Question 1 (2 points)

allochka39001 [22]

The solution to the polynomial expression since the power of the variable is in the second degree is 6.29 × 10² cm

<h3>What is the power of a variable?</h3>

The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.

Given that:

$\mathbf{= 2.150 \times 10^2 \ cm + 7.34 \times 10^2 \ cm - 3.2 \times 10^2 \ cm }$

So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.

i.e.

$\mathbf{= (2.150 + 7.34 - 3.2) \times 10^2\ cm }$

$\mathbf{= 6.29 \times 10^2\ cm }$
