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
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.

Mg + O2 + Mgo
1. Decomposition
2.Double Displacement 3.Synthesis
4. Single Displacement
Answer:
The correct reaction is as follows:
2Mg + O2 → 2MgO
3. Synthesis
Explanation:
Chemical reactions are of different types depending on how they occur. One of these types is called SYNTHESIS OR COMBINATION REACTION. A synthesis reaction is that reaction in which two atoms of two elements are chemically combined to form a single molecule or compound. That is;
A + B → AB.
This is the case in this question where atoms of Magnesium (Mg) and oxygen (O) reacted to form a single compound of Magnesium oxide (MgO). Hence, it is said to be a SYNTHESIS REACTION.
Which of the elements has the same Lewis dot structure as calcium (Ca)?
A.Barium (Ba)
B.Potassium (K)
C.Germanium (Ge)
D.Argon (Ar)
Answer:
[tex]\boxed {\boxed {\sf A. \ Barium (Ba)}}[/tex]
Explanation:
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.
Based on the answer choices, choice A is correct.

What’s the meaning of low metabolism
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.

The ability of iron to conduct electricity is a physical property of iron. *
True
False
Answer:
True
Explanation:
A physical property is a property that can be measured without changing the chemical composition of the substance.
The chemical composition of iron does not change when it conducts electricity so conductivity is a physical property.

What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same. Two or more than two atoms with different physical or chemical properties can not combine together to form an element.
A physical property is a property that can be measured without changing the chemical composition of the substance. So, ability of iron to conduct electricity is a physical property of iron

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
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.
