Answer:
As potential energy increases, kinetic energy decreases
It's an inverse relationship
Potential energy and kinetic energy are related through the law of conservation of energy. When potential energy increases, kinetic energy decreases, and vice versa, as energy is simply converted between these two forms.
The relationship between kinetic energy and potential energy lies within the law of conservation of energy. This law states that energy cannot be created or destroyed, only converted from one form to another.
Potential energy is the energy stored in an object due to its position in a force field or due to its configuration. For example, when you lift a book off the ground, it gains potential energy because of the work done against the force of gravity.
On the other hand, kinetic energy is the energy of an object due to its motion. The same book, when dropped, loses potential energy and gains kinetic energy as it falls towards the ground.
Hence, when potential energy increases, kinetic energy decreases, and vice versa. This is because the total energy (potential + kinetic) must be conserved, assuming no energy is lost to other forms like heat or sound.

(b)SO3 + H2O? (Assume an excess of water and that the product dissolves)
(c) SrO + H2SO4?
Explanation:
A balanced equation is defined as the one that has equal number of atoms of all the elements present on both reactant and product side.
(a)
Number of atoms on reactant side are as follows.
Mg = 1
O = 6
H = 3
Cl = 1
Number of atoms on product side are as follows.
Mg = 1
O = 9
H = 2
Cl = 2
So, to balance this equation we multiply by 2 on reactant side and multiply by 2 on product side.
Therefore, the balanced reaction equation is as follows.
(b)
Number of atoms on reactant side are as follows.
S = 1
O = 4
H = 2
Number of atoms on product side are as follows.
S = 1
O = 4
H = 2
Therefore, this equation is balanced as it has same number of atoms on both reactant and product side.
(c)
Number of atoms on reactant side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Number of atoms on product side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Therefore, this equation is balanced.
The main issues of using synthetic polymers include toxicity poor biocompatibility etc. Synthetic polymers stay non-degradable for ling time and make the surface polluted.
Natural polymers are naturally made substances such as cellulose, starch, glycogen etc. Polymers made by man are called synthetic polymers. Synthetic polymers are diverse and are made through several polymerization techniques.
PVC, polyethylene, polyesters Teflon etc. are very common polymers in daily life. A major class of synthetic polymers include plastics which are major pollutants nowadays.
Most of the synthetic polymers are non-biodegradable and will cause landfill issues. Some them are toxic in nature and might cause several health issues. Blending them with biodegradable polymers is a solution for this.

Answer:
Br - C ≡ N
Explanation:
To draw the Lewis line-bond structure we need to bear in mind the octet rule, which states that in order to gain stability each atom tends to share electrons until it has 8 electrons in its valence shell.
The most stable structure that respects these premises is:
Br - C ≡ N
It does not have any H atom.
Answer:
C₆H₆
Explanation:
Each border of the figure represents 1 atom of carbon. We have 6 borders = 6 atoms of carbon.
Each atom of carbon form 4 bonds. All the carbons are doing a double bond and a single bond with other carbons. That means are bonded 3 times. The other bond (That is not represented in the figure. See the image) comes from hydrogens. As we have 6 carbons that are bonded each 1 with one hydrogen. There are six hydrogens and the molecular formula is:
This structure is: Benzene
19.2 g of vinegar solution
Explanation:
Here we have the chemical reaction between acetic acid (CH₃COOH) and calcium carbonate (CaCO₃):
2 CH₃COOH + CaCO₃ → (CH₃COO)₂Ca + CO₂ + H₂O
number of moles = mass / molecular weight
number of moles of CaCO₃ = 0.8 / 100 = 0.008 moles
Knowing the chemical reaction, we devise the following reasoning:
if 2 moles of CH₃COOH react with 1 moles of CaCO₃
then X moles of CH₃COOH react with 0.008 moles of CaCO₃
X = (2 × 0.008) / 1 = 0.016 moles of CH₃COOH
mass = number of moles × molecular weight
mass of acetic acid (CH₃COOH) = 0.016 × 60 = 0.96 g
Now to find the volume of vinegar acid (solution of acetic acid) with a concentration of 5% (weight/volume) we use the following reasoning:
if there are 5 g of acetic acid in 100 mL of vinegar solution
then there are 0.96 g of acetic acid in Y mL of vinegar solution
Y = (0.96 × 100) / 5 = 19.2 g of vinegar solution

Answer:
The law is observed in the given equation.
Explanation:
CaCO₃ + 2HCI → CaCI₂ +H₂O + CO₂
In order to find out if the law of conservative mass is followed, we need to count how many atoms of each element are there in both sides of the equation:
As the numbers for all elements involved are the same, the law is observed in the given equation.
