What is the length in inches (in) of a 100-meter soccer field?
max2010maxim [7]

Answer:

3937 inches

1m = 39.37 inches.

However, we want to know how long a 100m soccer field is, so we have to times the value for 1m by 100.

Therefore, an 100m soccer field = 100 x 39.37 = 3937 inches

At 393 K, the pressure of a sample of nitrogen is 1.07 atm. What will the pressure be at 478 K, assuming constant volume?
True [87]

Answer:

About 1.301 atm

Explanation:

The formula that you should is PV=nRT, where P stands for pressure, V stands for volume, n stands for the number of moles, R stands for the universal gas constant, and T stands for temperature in Kelvin. Since the volume, number of moles, and universal gas constant don't change, you don't need to worry about them.

1.07V=393nR

PV=498nR

P=1.301 atm. Hope this helps!

Chemical properties of an element are primarily dependent upon Group of answer choices the electron configuration of the element
Margarita [4]

Answer:

The answer is "the electron configuration of the element".

Explanation:

Electronics are distributed in atomic and molecular orbit via electrons from an atom or a molecule.

It reflects a most frequent dependence on valence electrons in the outer.

Through analyzing the context of the regular periodic table, the individual atoms are helpful. That's also important to understand chemical connections, which hold electrons together. This similar approach helps to explain the specific characteristics of lasers or semiconductors for bulk materials.
