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.

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.

Explanation:
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
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.
what is the mass of of 3.20 X 10^23 particles of Co2?
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

How many moles are in 3.63 x 1023 atoms of Mn?
Answer:
0.603 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{3.63 \times {10}^{23} }{ 6.02 \times {10}^{23} } = \frac{3.63}{6.02} \\ = 0.60299...[/tex]
We have the final answer as
0.603 molesHope this helps you

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.

Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, the given statement is true.
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

Using the expression Ka=[H+][A−][HA] , explain how to determine which solution has the lower pH , 0.10MHF(aq) or 0.10MHC2H3O2(aq) . Do not perform any numerical calculations.
Answer:
0.10MHF(aq)
Explanation:
Given that:
[tex]K_a = \dfrac{[H^+][A^-]}{HA}[/tex] , to find the solution with a lower pH between 0.10MHF(aq) or 0.10MHC2H3O2(aq).
Recall that:
The higher the Ka value, the higher the ionization, hence more formation of protons in the solution. Also, higher H⁺ in solution results in a lower pH value.
Since HF have a higher Ka value, then HF solution will have a lower pH.
The acidity and alkalinity measure of a substance based on hydroxyl or hydrogen ion released is called pH. It is measured based on the pH scale that tells about the acidity and basicity of the substance.
0.10 M [tex]\rm HF[/tex] (aq) has lower pH.
The pH can be explained as:The acid dissociation constant ([tex]\rm K_{a}[/tex]) is given by,
[tex]\rm K_{a} = \dfrac{[H^{+}][A^{-}]}{[HA]}[/tex]
The value [tex]\rm K_{a}[/tex] of can be used for determining the lower and higher pH.When the [tex]\rm K_{a}[/tex] value is high then the ionization of the substance will be higher resulting in the release of more protons in the solution.When [tex]\rm H^{+}[/tex] is high then the pH will be lower and the solution will be more acidic.The [tex]\rm K_{a}[/tex] value of [tex]\rm HF[/tex] is more compared to the [tex]\rm HC_{2}H_{3}O_{2}[/tex] resulting in lower pH and more acidity.Therefore, 0.10 M [tex]\rm HF[/tex] (aq) has lower pH.

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.
