1kg=2.2lb
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) =

Pedro adds 3.23 moles of helium to a balloon that already contained 4.51 moles of helium creating a balloon with a volume of 9.87 liters. What was the volume of the balloon before the addition of the extra gas?
Answer:
7.The answer is 2.13 because if u add 3.23 and 4.51 and the answer is 7.74 and u add 2.13 to get 9.87. 3.23 + 4.51 + 2.13 is 9.87

The vat is made of metal. Why would it matter that the material from which the vat is made is metal ?
Answer:
Due its storing and holding ability.
Explanation:
It matter that the material from which the vat is made is metal because this vat is used for storing and holding liquids. Vat is a large container or tank that is used for storing or holding liquids in industrial sector. This vat is made of metal which increases its strength and durability. If the vat is made of wood or plastic so it can't hold huge amount of liquid or chemical due to its weak material so that's why it matters that the substance from which the vat is made is metal or not.

Question 1 0 Which of the following numerical expressions gives the number of moles in 5.0 g of CaO?
A) 5.0 g X 56 g/mol
B) 5.0 g / 56 g/mol
C) 56 g/mol / 5.0 g
D) 1/5.0 g X 1/56 g/mol
Answer: A
Explanation:
5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.
HOW TO FIND NUMBER OF MOLES:
The number of moles in a substance can be calculated by dividing the mass of that substance in grams by its molar mass in grams/moles. Number of moles = mass ÷ molar massIn this question, 5.0g of calcium oxide (CaO) was given. The molar mass of CaO is as follows:CaO = 40g/mol + 16g/mol = 56g/mol
Number of moles = 5.0g ÷ 56g/mol
Therefore, 5.0 g / 56 g/mol is the numerical expression that gives the number of moles in 5.0 g of CaO.

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.

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.
