what is the mass of of 3.20 X 10^23 particles of Co2?
Answers
Answer:
Mass = 23.36 g
Explanation:
Given data:
Number of particles of CO₂ = 3.20 ×10²³
Mass of CO₂ = ?
Solution:
1 mole contain 6.022×`10²³ particles,
3.20 ×10²³ particles × 1 mol / 6.022×`10²³ particles
0.531 mol
Mass of CO₂:
Mass = number of moles × molar mass
Molar mass = 44 g/mol
Mass = 0.531 mol× 44 g/mol
Mass = 23.36 g

A solution is saturated in CO2 gas and KNO3 at room temperature. What happens when the solution is warmed to 75°C?
solid KNO, precipitates out of the solution
gaseous CO2 bubbles out of the solution
solid KNO, precipitates out and gaseous CO2 bubbles out
nothing happens; both CO2 and KNO3 remain in solution
Answers
Answer:
gaseous CO2 bubbles out of the solution
Explanation:
We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.
Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.
Thus the solid becomes more soluble at 75°.
When the solution is warmed to 75°C ; ( B ) gaseous CO₂ bubbles out of the solution
When a solution is saturated with CO₂ ( gas ) and KNO₃ ( s ) has its temperature increased above the room temperature to about 75°C the solubility of the gas CO₂ will decrease, because the solubility of gas in a solution decreases with an increase in temperature while the solubility of a solid increases with increase in temperature.
Since the solubility of the gas decreases the gas will escape as bubbles ( CO₂ bubbles ).
Hence we can conclude that When the solution is warmed to 75°C ; ( B ) gaseous CO₂ bubbles out of the solution.

Click Oil Basics to explore the natural resources needed for the production of plastics. Use the information to answer the question. Which of these ingredients is important in making plastics? carbon dioxide particulate matter natural gas plant liquids volatile organic compounds
Answers
Answer:
natural gas plant liquids
Explanation:
The ingredients that are important for the production of plastics are natural gas and plant liquids. The correct options are c and d.
What is plastic?Polymers are the primary component of a wide variety of synthetic or semisynthetic materials known as plastics. Due to their versatility and importance to civilization, plastics are a very important material. This is due to the fact that plastics can be bent and molded into a variety of objects, from plates to phones.
Radiation is to blame for this becoming possible. People who manufacture plastics can heat polymers sufficiently to allow them to bend by employing radiation. They can then be formed into a variety of things when this occurs.
Plastics are made from natural gases and liquids obtained from plants.
Therefore, the correct options are c, natural gas, and d, plant liquids.

When an electron moves from a lower energy level to a higher energy level, the atom:
A. absorbs light
B. gives off light
C. becomes a new isotope
Answers
Answer:
A. absorbs light
Explanation:
For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.
In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.
When said electron comes back to the lower energy level, the atom will conversely give off light.

Lewis dot structures illustrate the valence electrons in an element.
Valence electrons are the outermost electrons in an atom that bond with other atoms by accepting or releasing electrons. The groups, or columns, of the Periodic Table have the same number of valence electrons.Calcium is in group 2.
The other elements in this group are:
Beryllium, Magnesium, Strontium, Barium, and RadiumSo, all these elements have the same lewis dot structures because they have the same number of valence electrons.

What’s the meaning of low metabolism
Answers
Answer:
A person with a "low" (or slow) metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
meaning of normal metabolism-Metabolism is the process by which your body converts what you eat and drink into energy. Even when you're at rest, your body needs energy for functions such as breathing, circulating blood and repairing cells. The energy your body uses for these basic functions is known as your basal metabolic rate.
A person with a low metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
Signs of a slow metabolism
-You have gas.
-You crave sugar.
-You keep gaining weight.
-It's tough to lose weight.
-You always feel bloated.
-You have hypothyroidism.
-You easily develop cellulite.
-Your blood sugar is too high.
