A balloon is inflated to a volume of 1.25L .If the temperature of the air inside is cooled from 35°C to 15°C , what will be the final volume of the balloon?
Answers
Answer:
V₂ = 1.17 L
Explanation:
Given data:
Initial volume of balloon = 1.25 L
Initial temperature = 35°C
Final temperature = 15°C
Final volume = ?
Solution:
Initial temperature = 35°C (35+273.15K = 308.15 K)
Final temperature = 15°C (15+273.15 K = 288.15 K)
The given problem will be solve through the Charles Law.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 1.25 L × 288.15 K / 308.15 k
V₂ = 360.2 L.K / 308.15 k
V₂ = 1.17 L
the difference between these two chemical formulas: 4 H2O and H8O4.
Answers
Answer:
Explanation:
The given chemical formula is;
4H₂O H₈O₄
H₂O signifies 2 atoms of hydrogen bonding with 1 atom of oxygen
H₈O₄ signifies 8 atoms of hydrogen bonding with 4 atoms of oxygen
The 4 coefficient before H₂O signifies the number of moles.
It appears H₂O is 4 moles of water
H₈O₄ is 1 mole of the compound
The number of moles of each of the compound differs.
The difference between the two chemical formulas has been on the basis of the number of the molecules present. There have been 4 molecules of [tex]\rm H_2O[/tex], while only 1 molecule of [tex]\rm H_8O_4[/tex].
The chemical formula has been used for the determination of the number of atoms of each element present in the compound.
The chemical formula 4 [tex]\rm H_2O[/tex] gives the idea that there have been 4 molecules of water, with each molecule has consisted of 2 hydrogens and 1 oxygen atom. The total number of atoms has been 8 hydrogen atoms and 4 oxygen atoms.
The chemical formula [tex]\rm H_8O_4[/tex] gives insight into the presence of 1 molecule having 8 atoms of hydrogen and 4 atoms of oxygen.
The similarity in the chemical formula has been the presence of the same number of atoms. The difference between the two chemical formulas has been on the basis of the number of the molecules present. There have been 4 molecules of [tex]\rm H_2O[/tex], while only 1 molecule of [tex]\rm H_8O_4[/tex].

C

D
exocytosis.
Answers
Answer:
A endocytosis
Explanation:
The process by which a cell takes in a large particle is called endocytosis. Therefore, the correct option is option A.
What is endocytosis?Endocytosis is the procedure by which molecules are actively transported into the cell by being engulfed by its membrane. All cells use endocytosis and exocytosis to transport substances that cannot passively cross the membrane. Exocytosis serves the opposite purpose by ejecting molecules from the cell.
The requirement for homeostasis ensures an equal flow all molecules into and out of a cell, like all of the body's systems. This indicates that the number of molecules exocytosis and endocytosis both equal the number of molecules into the cell. The two systems work together to maintain a balance between nutrients and waste that is necessary for normal cell growth and function. The process by which a cell takes in a large particle is called endocytosis.
Therefore, the correct option is option A.

True or false? A metal will always be produced at one electrode during electrolysis.
Answers
Yes, a metal will always be produced at one electrode during electrolysis.
What is electrode?
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit.
An electrode can be anode or cathode. During electrolysis, that is , the decomposition of a chemical compound by electricity, a metal will be deposited at the cathode.
Thus, a metal will always be produced at one electrode during electrolysis.

а
Gallium
b Germanium
C Calcium
d Magnesium
Answers
Answer:
gallium and germanium
Explanation:
hope it will help you
The element that would form +4 ions is Germanium. The correct option is b Germanium
From the question,
We are to determine which of the given elements will form +4 ions.
Gallium belongs to group 13 and will form +3 ions because the its oxidation state is +3.
Germanium belongs to group 14 and it forms stable oxidation state of +2 and +4. Therefore, Germanium will form +4 ions.
Calcium belongs to group 2 on the periodic table. Its oxidation state is +2 and it forms +2 ions.
Magnesium also belongs to group 2 on the periodic table. Its oxidation state is +2 and it forms +2 ions.
Hence, the element that would form +4 ions is Germanium. The correct option is b Germanium
