Answer:
Coefficient
Explanation:
Chemical equation:
aA + bB → dD
This equation shows that reaction is balanced by coefficient q,b and d.
Reactant coefficients Product Coefficient
A a D d
B b
Every balanced equation follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass. The numbers 6 with CO₂, 6 with H₂O and 6 with O₂ are coefficient which balance the equation.
Answer:
12, 28, 16
Explanation:
If we are trying to find mass, neutrons are our guy. 28 "mass points" means 28 neutrons. Each neutron is one point
We know there are 12 protons and electrons if we look at a table of elements, the number in the top-left is always the number of protons and we can subtract mass from the protons to get our electrons
<u>Answer:</u> The new pressure for oxygen gas is 6 atm.
<u>Explanation:</u>
To calculate the new pressure of the gas, we use the equation given by Boyle's Law.
This law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
or,
where,
are the initial pressure and volume of the gas.
are the final pressure and volume of the gas.
We are given:
Putting values in above equation, we get:
Hence, the new pressure for oxygen gas is 6 atm.
Answer:
a note? well alright
Explanation:
<em><u>Polygenic disease:</u></em> (the defintion)
A genetic disorder that is caused by the combined action of more than one gene.
<u>Polygenic conditions</u><u>:</u> hypertension, coronary heart disease, and diabetes.
This is so because such disorders depend on the simultaneous presence of several genes, they are not inherited as simply as are single-gene diseases.
