Answer:
D.
Explanation:
To convert from grams of a substance to moles of a substance, you use molar mass as a conversion factor. Sodium's molar mass is 22.99 grams per mole. To cancel out grams, you need to place grams on the bottom and moles on the top.
Atoms share pairs of electrons: covalent
Atoms transfer electrons: ionic
Atoms have electrostatic attraction:
Atoms bond together:Both
The kinetic theory state about the relationship between the speed and temperature of gas molecules "As the temperature increases, the speed of gas molecules increases".
<u>Option: </u>C
<u>Explanation:</u>
The temperature relates to a gas, according to the kinetic theory of gases, influences the rate of motion of the gas particles. The higher the gas temperature, the faster the gas particles are moving; the reverse is true, too.
This is because the gas particles gain more kinetic energy as the temperature of the gas increases, and therefore move faster and collide more with each other and the container walls.The rate of a gas's molecules is proportional to the temperature, and is inversely proportional to the gas's molar mass.
Answer:
An organic chemical compound consisting solely of hydrogen and carbon atoms is a hydrocarbon. Hydrocarbons are compounds that occur naturally and form the basis of crude oil , natural gas, coal and other significant sources of energy.
Answer:
The best-known threat comes from human pressures, driven by agriculture, residential, and commercial expansion into cactus habitats. But the worst offender, the scientists were surprised to find, is the illegal trade of cactus plants and seeds, affecting 47 percent of the threatened species. There are lots of different variations of cacti.
