<u>Answer:</u>
CHCl3 has dipole-dipole interactions.
<u>Explanation:</u>
Trichloromethane has a electric dipole moment permanently pointing along the line parallel with the Hydrogen carbon axis.Dipole-dipole interactions are said to be intermolecular force of attractions that is formed from two permanent dipoles interacting.
These type of interactions are occurring when one of the partially charged formed molecule are being attracted to an opposite partially charged molecule nearby . The molecules align in a state that the positive end of one of the molecule gets interacting with the negative end of the another molecule.
Answer: The Kelvin scale is related to the Celsius scale. The difference between the freezing and boiling points of water is 100 degrees in each, so that the kelvin has the same magnitude as the degree Celsius.
Explanation:
Celsius is, or relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as a unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death.
K = °C + 273.15
°C = K − 273.15
Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalence is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the triple point of specially prepared water. This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C.
Add the weight of chromium, nickel and iron to get 25 pounds. Then divide the weight of chromium by the weight of the stainless steel to get 18%. Then find 18% of 25 g which is 4.5 g.
"They are harder than alkali metals" is a characteristic property of the alkaline earth metals.
<u>Option:</u> C
<u>Explanation:</u>
The strength of metallic bond is stronger in alkaline earth metals than alkali metals because of the existence of 2 electrons in its outermost or valence shell relative to alkali metal which has only 1 electron in valence shell. Thus alkaline earth metals are therefore harder than the alkali metals.
They are considered alkaline since they formulate solutions that have a pH higher than 7, rendering them alkaline or bases. Radium is produced by uranium decay, not all alkaline elements are radioactive. It's very toxic, and the handling is risky. Calcium and magnesium are essential for animals and plants.
According to geography4kids mechanical weathering is the process of breaking big rocks into little ones this process usually happens near the surface of the planet temperature also affects the land the cool nights and hot days always cause things to expand and contract that movement can cause rocks to crack and break apart
