is required for the transformation of oxaloacetic acid into malic acid.
<h3>What is malic acid?</h3>
Malic acid is sour and acidic. This helps to clear away dead skin cells when applied to the skin.
The conversion of oxaloacetic acid into malic acid takes place in 
plants through the cycle by the process of photosynthesis.
Carboxylation of pyruvate produces oxaloacetate (OAA). This is an energy-requiring reaction that uses adenosine triphosphate (ATP).
Hence, is required for the transformation of oxaloacetic acid into malic acid.

Answer:
Inertia
Explanation:
According to Galileo, the motion of a projectile can be described according to two principles.
Firstly, he argued that when the projectile is fired, it moves in straight line until it looses its impetus and falls to the ground.
The horizontal motion of the projectile is explained by the theory of inertia. According to Galileo, the two independent motions of the projectile all together leads to a mathematical curve which completely describes the motion of a projectile.
The law of conservation of mass maintains that in all chemical reactions mass is conserved, this ensures that chemical reactions are balanced.
<h2>What is the law of conservation of mass?</h2>
It is a principle of chemistry that states that the quantities of the masses involved in a given reaction must be constant, that is, the quantity of reactants consumed is equal to the quantity of products formed.
<h3>Characteristics of the law of conservation of mass:</h3>
- The chemical composition of a substance remains constant.
- In a chemical reaction certain coefficients are used to balance the equation and this will allow the number of atoms to be equal on both sides.
Therefore, we can conclude that the law of conservation of mass is the one that holds that, within a closed system, the amount of matter before and after a transformation is always the same.

Pb(NO3)2+2HCl=PbCl2+2HNO3
Step 2
Find # of moles of Pb
13.87g Pb(NO3)2 x 1 mol/331.22=.041875 mol Pb(NO3)2
Step 3
Use balanced equation to find weight of Pb(NO3)2
.041875mol Pb x 1 mol Cl2/1mol Pb x 70.90g/1 mol Cl2=2.9689g Cl2
.041875 mol Pb x 207.2/1mol Pb=8.6765g Pb
=11.65g</span>
Answer:
Explanation: The lowest pressure in a laboratory is 4.0×10^-11Pa
Using Ideal gas equation
PV = nRT
P= 4.0×10^-11Pa
V= 0.020m^3
T= 20+273= 293k
n=number of moles = m/A
Where m is the number of molecules and A is the Avogradro's number=6.02×10²³/mol
R=8.314J/(mol × K)
PV= m/A(RT)
4.0×10^-11 ×0.020 = m/6.02×10²³(8.314×293)
m = 4.0×10^-11×0.020×6.02×10^23 / (8.314×293)
m = 1.98×10^8 molecules
Therefore,the number of molecules is 1.98×10^8
