Nitrogen: Non-Metal
Krypton: Non-Metal, Noble Gas
Chlorine: Non-Metal
Sulfur: Non-metal
Explanation:
A gas is confined in a rectangular tank 25.0 cm long, 8.0 cm high, and 10.4 cm wide. If the density of the gas is 19.3 g/L.

What is density?</h3>
The substance's mass per unit of volume is known as its density (volumetric mass density or specific mass).
The density of a pure substance is equal to its mass concentration in numbers. Density varies widely among materials and may be important in relation to packaging, purity, and buoyancy. The densest known elements under conditions of normal temperature and pressure are osmium and iridium.
It is occasionally substituted by the dimensionless quantity "relative density" or "specific gravity," which is the ratio of the density of the material to that of a standard material, typically water, to make density comparisons across different systems of units easier.

Answer:
1.54grams
Explanation:
Molarity of a solution = n/V
Where;
n = number of moles (mol)
V = volume (L)
Based on the information given in this question;
Volume of NaOH solution = 5.0 × 10ml
= 50ml = 50/1000 = 0.050 L
Molarity = 0. 77 M
Using; Molarity = n/V
0.77 = n/0.05
n = 0.77 × 0.05
n = 0.0385mol
To find the mass (grams) of NaOH in the solution, we use the following formula:
mole (n) = mass/molar mass
Molar mass of NaOH = 23 + 1 + 16 = 40g/mol
0.0385 = mass/40
mass = 0.0385 × 40
mass = 1.54grams.
Body waves travel through the interior of the Earth. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. the surface of the Earth).
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
P-waves are compression waves. They can propagate in solid or liquid material.
S-waves are shear waves. They only propagate in solid material.
By studying the trajectories of S-waves, scientists could prove that the Earth had a liquid outer core.
