That should be glycolysis
Explanation:
To delineate the the nature of the bonds that would be formed between the two elements, let us first write the electronic configuration of the two species;
Be = 2, 2
F = 2, 7
Beryllium is a metal with two valence electrons whereas fluorine is a halogen with seven valence electrons.
When Be loses two electrons it becomes isoelectronic with He;
Be → Be²⁺ + 2e⁻
Also, when fluorine gains an electron, it becomes isoelectronic with Ne;
F + e⁻ → F⁻
This loss and gain of electrons between the two elements creates an electrostatic attraction them and they enter into an electrovalent bond.
Hence;
Be²⁺ + 2F⁻ → BeF₂
Answer:
<u>0.993 atm</u>
Explanation:
This can be calculated using Dalton's law of partial pressure which states that if two or more gases are mixed together, the total pressure exerted by the mixture of the gases is eqaul to the sum of the pressure which individual gas woud exert if it occupied the volume of of the mixture alone.
Therefore P (total) = P (gas A) + P (gas B)
Since pressure of gas A = 1.0 atm
pressure of gas B = 1.0 atm
gas constant R = 0.08206 atm L mol-1 K-1
standard temperature = 273K
Note that atm is a unit for pressure
Number of mole of gas A, n=PV/RT
= 1 x 2 / 0.08206 x 273
= 0.088306 mole
Number of mole of gas B
= 1 x 1 / 0.08206 x 273
= 0.044644 mole
Total pressure can be gotten using P(total) = (n(total)RT)/V(total)
= [(0.044644 + 0.088306) x 0.08206 x 273] / 3
= <u>0.993 atm</u>

Answer:
When 45 gram of total mass of reactant react 45 gram of product will also produced
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
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.
In a similar way,
2Na + 2H₂O → 2NaOH + H₂
45 g = 45 g
when 45 gram of total mass of reactant react 45 gram of product will also produced. (2NaOH + H₂ = 45 g)
