Which type of hybridization is observed when central atom is located at the centre of regular tetrahedron
Answers
Answer:
sp3 hybridization
Explanation:
Hybridization means the mixing of atomic orbitals to yield hybrid orbitals with characteristics that are different from that of the isolated atomic orbitals before the combination.
sp3 hybridization occurs when one s orbital is mixed with three p orbitals to yield four sp3 hybrid orbitals which can be used to bond to a central atom.
The central atom is then located at the center of a regular tetrahedron at a bond angle of 109°.

Answer:
21091mg of aspirin the person need to consume
Explanation:
To solve this question we must find the mass of the person in kg. Knowing the lethal dose for aspirin is 400mg/kg of person, we can find the amount of aspirin that the person need to consume to get a lethal dose:
Mass person:
116lb * (1kg / 2.2lb) = 52.7kg
Lethal dose:
52.7kg * (400mg / kg) =

How many moles of iron would be needed to react with 3.82 moles of
oxygen
Answers
The number of moles of iron (Fe) required to react with 3.82 moles of oxygen is 5.09 moles
Balanced equation
3O₂ + 4Fe —> 2Fe₂O₃
From the balanced equation above,
3 moles of O₂ reacted with 4 moles of Fe
How to determine the moles of FeFrom the balanced equation above,
3 moles of O₂ reacted with 4 moles of Fe
Therefore,
3.82 moles of O₂ will react with = (3.82 × 4) / 3 = 5.09 moles of Fe
Thus, 5.09 moles of Fe is needed for the reaction

Determine the pH of a 2.8 ×10−4 M solution
of Ca(OH)2.
Answers
Answer:
pH = 10.75
Explanation:
To solve this problem, we must find the molarity of [OH⁻]. With the molarity we can find the pOH = -log[OH⁻]
Using the equation:
pH = 14 - pOH
We can find the pH of the solution.
The molarity of Ca(OH)₂ is 2.8x10⁻⁴M, as there are 2 moles of OH⁻ in 1 mole of Ca(OH)₂, the molarity of [OH⁻] is 2*2.8x10⁻⁴M = 5.6x10⁻⁴M
pOH is
pOH = -log 5.6x10⁻⁴M
pOH = 3.25
pH = 14-pOH
pH = 10.75Consider the following reaction: Solid zinc was added to 1.0 M HC1.

Answers
Answer:
1.25 mL/s
Explanation:
Your are told that 25.0 mL of H2 was produced 20 seconds. This is equal to rate 25/20 = 1.25 mL/s
When a reaction progresses, the reactant concentration gradually decreases and the product concentration gradually increases. Here the rate of the reaction is 1.25 mL/s.
What is rate of reaction?The rate of a chemical reaction is defined as the rate of decrease of concentration of a reactant or the rate of increase of concentration of a product. The rate of the reaction is usually expressed in units mol L⁻¹s⁻¹. The rate of the reaction are affected by several factors like concentration of the reactants, temperature, etc.
An equation which expresses the experimentally observed rate of a reaction in terms of the molar concentration of the reactants which determine the rate of the reaction is called rate equation.
Here it is seen that 25.0 mL of H2 was produced 20 seconds. So the rate is given as:
Rate = 25/20 = 1.25 mL/s
Thus the rate of the reaction is 1.25 mL/s.
