Answer:
V₂ = 300 cm³
Explanation:
Given data:
Initial pressure = 302 KPa
Initial volume = 600 cm³
Final pressure = 604 KPa
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
302 KPa × 600 cm³ = 604 KPa× V₂
V₂ = 181200 KPa.cm³ / 604 KPa
V₂ = 300 cm³
Answer: The organic compound used to create fragrances in perfume industry are ester.
Explanation:
Organic compounds are defined as the compounds in which a covalent bond is present between a hydrogen and a carbon atom. These are also known as hydrocarbons.
Esters are an organic compound which have a pleasant and fruity smell and is used in the perfume industry.
Therefore, the organic compound used to create fragrances in perfume industry are ester.
Answer:
NaClO₄
Solution:
Let us calculate the oxidation state of Chlorine in each compound one by one;
1) NaClO
O.N of Na = +1
O.N of O = -2
So,
(+1) + (Cl) + (-2) = 0
1 + Cl - 2 = 0
Cl = -1 + 2
Cl = +1
2) NaClO₃
(+1) + (Cl) + (-2)3 = 0
(+1) + (Cl) - 6 = 0
1 + Cl - 6 = 0
Cl = -1 + 6
Cl = +5
3) NaClO₂
(+1) + (Cl) + (-2)2 = 0
(+1) + (Cl) + (-4) = 0
1 + Cl - 4 = 0
Cl = -1 + 4
Cl = +3
4) NaClO₄
(+1) + (Cl) + (-2)4 = 0
(+1) + (Cl) + (-8) = 0
1 + Cl - 8 = 0
Cl = -1 + 8
Cl = +7
The mass of the solution of sugar and water is 120 grams.
Mass is the quantity of matter of a physical body.
The mass of the sugar is given is 20g
The mass of the water is 100 g.
100 + 20 = 120 gram
Thus, the mass of the solution of sugar and water is 120 grams.

Control Group:
In the experiment, the Experimental Group represents ducks in cold water, while the Control Group represents ducks in room temperature water. The scientist is testing whether water temperature affects duck swimming speed.
In the experiment described, the scientist is exploring whether the temperature of the water affects the speed of swimming of ducks. The Experimental Group in this scenario represents the ducks that are swimming in cold water. The scientist expects that these ducks will swim faster, based on the original hypothesis. On the other hand, the Control Group represents the ducks that are swimming in room temperature water. This group serves a basis for comparison to help the scientist determine what changes (if any) occur when the variable (water temperature) is altered.
