What is the molar solubility of lead phosphate in water in moles?
Please help?!
Answer:
Now, the molar solubility of lead(II) phosphate in water is said to be equal to 6.2⋅10−12mol L−1 . This means that in one liter of water, presumably at room temperature, you can only hope to dissolve 6.2⋅10−12 moles of lead(II) phosphate.

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) =

What is the molecular geometry of carbon tetrachloride (CC1,)?
O linear
O trigonal planar
O tetrahedral
O trigonal pyramidal
Answer:
tetrahedral
As carbon has no 4 valence electrons that are occupied by 4 chlorine atoms, we get 0 lone pair in carbon and sp3 hybridisation which leads to tetrahedral shape.
How many moles of iron would be needed to react with 3.82 moles of
oxygen
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

cause [A] to increase
cause [B] to increase
gave no effect
cannot be determined
Answer:
cause [B] to increase
Explanation:
We have to have it behind our minds that; for an exothermic reaction, when the temperature is increased, the value of the equilibrium constant decreases. On the other hand, for an endothermic reaction, increasing the temperature increases the value of the equilibrium constant.
In this particular case, increasing the temperature decreased the equilibrium constant from K = 1.6x104 to K = 1.8x10-5 meaning that the equilibrium constant decreased with increase in temperature. This means that the reaction is exothermic and a decrease in temperature will favour the forward reaction hence more B is produced.

Answer: 3 - outer covering
Explanation:
What physical structure has spines that protect the plant from predators?
1)Flower
2)Pistil
3)Outer covering
4)Reproductive organs
Outer covering is the physical structure has spines that protect the plant from predators. Therefore, option C is correct.
What do you mean by the predators ?Predators are living things that go for and kill prey. The term "prey" refers to the living things that predators eat. Both carnivores and omnivores may be predators. Predators include lions, tigers, sharks, and snakes.
Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether the victim dies, each sort of predation may be classed.
Plants are shielded against parasite invasion by their epidermis. It creates an external covering for plant organs that are constantly in contact with the outside world. This epidermis is further protected by a cuticle, which is a layer of fatty material.
Thus, option C is correct.

Consider the following reaction: Solid zinc was added to 1.0 M HC1.
After 20.0 s, the temperature of the container increased by 0.5°C and 25.00 mL of
H2 was produced. The rate of this reaction was
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.

When water reacts with potassium metal the hydrogen produced ignites explosively on the surface of water .What cause the ignition
Answer:
Pottasium reacts with water vigorously and the reation is exothermic. The heat released causes the hydrogen released to ignite
Explanation:
Describe some of the solutions that engineers might propose for maximizing the percent yield of hydrogen from discarded wood.
A possible solution for maximizing the percentage of hydrogen in discarded wood is to design a machine that can collect more effectively all the gases and separate hydrogen from other gases.
How do people produce hydrogen using discarded wood?Discarded wood and other products can still produce important elements nitrogen, methane, and hydrogen. This is possible through combustion that releases these elements in a gas.
What is the limitation of this method?This is a new method and it is still not completely developed. Due to this, the equipment is not as efficient as one would like, for example, all gases are initially collected together but this is a problem if only one gas is needed.
Based on this, a potential solution would be to create a machine that is more efficient in collecting and separating the gases.
