Answer is covalent bonds.
Diamond is a giant covalent structure in which: each carbon atom is joined to four other carbon atoms by strong covalent bonds. the carbon atoms form a regular tetrahedral network structure. there are no free electrons.
<span>Charles' law says "at a constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature".
V </span>α T
Where V is the volume and T is the temperature in Kelvin of the gas. We can use this for two situations as,
V₁/T₁ = V₂/T₂
V₁ = 2.00 L
T₁ = 40.0 ⁰C = 313 K
V₂ = ?
T₂ = 30.0 ⁰C = 303 K
By applying the formula,
2.00 L / 313 K = V₂ / 303 K
V₂ = (2.00 L / 313 K) x 303 K
V₂ = 1.94 L
Hence, the volume of the balloon at 30.0 ⁰C is 1.94 L
Ammonia is a molecule that consists of a single nitrogen atom and three hydrogen atoms. The chemical formula is NH4. The atoms within the molecule have covalent bonds. The main type of attractive force between ammonia molecules are hydrogen bonds due to the three nitrogen-hydrogen bonds.
Answer:
mass
Explanation:
How much does air weigh? It might not seem like it, but air has weight. Anything with mass has weight, and we know air has mass because (for example) we can feel it when the wind blows. The total weight of the atmosphere exerts a pressure of about 14.7 pounds per square inch at sea level.

Answer:
f = frequency = 590,000 Hz ===> 59×10^4 Hz
λ = Wavelength = ?
c = Speed of light in a vacuum = 3 × 10^8 m/s
** Hz = 1/sec
