Answer:
Carbon Monoxide / Carbon Dioxide / Sulfur and Nitrogen Dioxide
Explanation:
Answer: 1
Explanation:
a mole is always equal to 6.02 x 10^23 molecules, or in this case, atoms
so to find the number of moles, divide total atoms / 6.02 x 10^23
total atoms = 6.02 x 10^23
6.02 x 10^23 / 6.02 x 10^23 = 1
so 1 mole
Answer:
1. 2.33 L.
2. 111.74 °C.
Explanation:
<em>1. 3.0 L of a gas is at a temperature of 78°C. Find the volume of the gas at standard temperature.</em>
- Charles’ Law states that at constant pressure, the volume of a given quantity of a gas varies directly with its temperature.
V ∝ T.
<em>∴ V₁T₂ = V₂T₁.</em>
V₁ = 3.0 L, T₁ = 78°C + 273 = 351 K.
Standard temperature = 0.0 °C.
<em>V₂ = ??? L</em>, T₂ = 0.0 °C + 273 = 273 K.
∴ V₂ = V₁T₂/T₁ = (3.0 L)(273 K)/(351 K) = 2.33 L.
<em>2. At what temperature (in oC) would the volume of a gas be equal to 45.7 L, if the volume of that gas was 33.9 L at 12.4oC?</em>
<em></em>
<em>∵ V₁T₂ = V₂T₁.</em>
V₁ = 33.9 L, T₁ = 12.4°C + 273 = 285.4 K.
V₂ = 45.7 L, <em>T₂ = ??? K.</em>
∴ T₂ = V₂T₁/V₁ = (45.7 L)(285.4 K)/(33.9 L) = 384.74 K.
∵ T(K) = T(°C) + 273.
∴ 384.74 K = T(°C) + 273.
∴ T(°C) = 384.74 K - 273 = 111.74 °C.
The only types of natural forces are gravitation, electromagnetism, the weak interaction, and the strong interaction. So no, chemical is not an example of a natural force.
I hope this helps.
Answer:
A covalent bond is present between two non-metals that share electrons in their molecular structure.
Explanation:
Examples of covalent bonds may be between carbon dioxide or water. And there may be three types of covalent bonds such as ionic, covalent and polar. In the first type, there is a transfer of an electron resulting in a gain for one of the atoms. In the second type, there is a sharing of electrons between the atoms. The third type is characterized by a difference in electronegativity between atoms.
