Answer:
0.1795 M
Explanation:
From the given information:
The equation is:
From the above equation, the reaction will go to completion due to the strong base:
At the equivalence point, moles of acid (HF) will be equal to moles of base (KOH)
Thus. since moles of HF = moles of KOH
Then; 0.020 × 0.393 M = 0.02379 × (x) M
(x) M = 
(x) = 0.3304 M
Thus, the molarity of KOH = 0.3304 M
Using the balanced neutralization reaction;
moles of HF = moles of KOH = moles of conjugate base = 0.00786 mol
∴
Volume = 0.020 L + 0.02379 L
Volume = 0.04379 L
Volume of the solution = 0.04379 L
Therefore; Molarity = 
Molarity = 
Molarity = 0.17949 mol/L
= 0.1795 M
Molecular simulation is the part of the drug discovery life cycle that most likely uses quantum computing.
<h3>What is drug discovery?</h3>
Drug discovery refers to the process to identify and validate medications in pharmaceutical research.
Drug discovery exploits computational approaches based on quantum modeling to accelerate this process.
In conclusion, molecular simulation is the part of drug discovery associated with quantum computing.

Answer: Rhenium is used as an additive to tungsten- and molybdenum-based alloys to give useful properties. These alloys are used for oven filaments and x-ray machines. It is also used as an electrical contact material as it resists wear and withstands arc corrosion.
Explanation:
Ionic Bonding:
This type of bonding occurs when atoms want to fulfil their valence shells by taking/giving electrons to other atoms. This, leads to completed valence shells in most cases and ionisation of both elements. The opposite charges cause the elements to stick together because opposites attract.
Covalent Bonding:
This type of bonding occurs when electrons are shared between atoms to each fill up their own valence shells by sharing. The balance between the attraction forces and repulsion forces between the shared electrons is called covalent bonding.

Answer:
•How do you find the delta H per grams in an chemical formula
➢ Subtract the sum of the heats of formation of the reactants from that of the products to determine <u>delta H: delta H = –110.53 kJ/mol</u> – (–285.83 kJ/mol) = 175.3 kJ.
