Based on the melting points of both substances in comparison with the table what's your guess

Fynjy0 [20]

Based on the melting points of both substances in comparison, my guess is Sodium chloride and glucose are the mystery compounds.This is further explained below.

<h3>What is Sodium chloride?</h3>

Generally, Salt's chemical name is sodium chloride. It is an electrolyte's job to keep your body's fluid balance in check.

In conclusion, Sodium chloride and glucose are the likely candidates based on their relative melting points.

The proton number of barium (Ba) is 56. It is in Group II of the periidic table how many electrons would you expect a barium ato

ella [17]

Answer:

A barium atom would be expected to contain 2 electrons in its outer energy level.

Explanation:

The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.

The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.

That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

What is true of tectonic plates?

kupik [55]

Answer:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. ... The lithosphere includes the crust and outer part of the mantle.

A sample of Freon-12 (CF2Cl2) occupies 2.842 x 101 L at 331 K and 2.525 x 102 kPa. Find its volume (in L) at standard temperatur

Angelina_Jolie [31]

We have to first find the number of moles of Freon-12 in the sample using the ideal gas law equation
PV = nRT
n = $\frac{PV}{RT}$
since the number of moles at both conditions given and at stp we can write the following formula
$\frac{P1V1}{RT1} = \frac{P2V2}{RT2}$
where parameters for the given conditions are on the left side and parameters for STP conditions are on the right side of the equation
where P1 - pressure - 252.5 kPa
V1 - volume - 28.42 x 10⁻³ m³
R - universal gas constant
T1 - 331 K

STP conditions
P2 - 101 325 Pa
T2 - 273 K

substituting these values in the equation

$\frac{252 500Pa*28.42*10 ^{-3}m^{3} }{R*331K} = \frac{101325 Pa*V}{R*273 K}$

V = 58.41 L
Volume at STP is 58.41 L
