What is base isolation?Base isolation is a technique developed to prevent or minimise damage to buildings during an earthquake.
A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure). By separating the structure from its base the amount of energy that is transferred to the superstructure during an earthquake is reduced significantly.
Hence, option D is correct.

Calculate the volume occupied by 2.00 moles of H₂ at 300.0 K and 1.25 atm
Answers
Answer:
V = 39.38 L
Explanation:
Given that,
No. of moles of H₂, n = 2
Temperature, T = 300 K
Pressure, P = 1.25 atm
We need to find the volume occupied by the gas. We can use the ideal gas law to find it such that,
[tex]PV=nRT[/tex]
Where
R is gas constant, R = 0.08205 L-atm/mol-K
V is volume of the gas
Rearranging the above formula for V. So,
[tex]V=\dfrac{nRT}{P}\\\\V=\dfrac{2\times 0.08205\times 300}{1.25}\\\\V=39.38\ L[/tex]
So, the volume occupied by the gas is 39.38 L.

A tower built of Iron is 500 meter tall. What is the change in height (m) if it is exposed to 25 0 Celsius during summer and at 1.00 Celsius during winter. α iron = 1.2 x 10-5/ Celsius
Answers
Answer:
-0.144 m
Explanation:
From the question,
α = Δh/(h₁Δt).................... Equation 1
Where α = coefficient of linear expansivity of iron, Δh = change in height, h₁ = initial height, Δt = change in temperature.
make Δh the subject of the equation
Δh = α(h₁Δt)..................... Equation 2
Given: α = 1.2×10⁻⁵/°C, h₁ = 500 m,
Δt = (t₂-t₁) Where t₂ and t₁ = Final and initial temperature respectively.
Δt = (1-25) = -24 °C
Substitute these values into equation 2
Δh = 1.2×10⁻⁵[500×(-24)]
Δh = 1.2×10⁻⁵(-12000)
Δh = -0.144 m
A gardener cut her finger while pruning shrubs. She noticed that after two weeks the wounds had nearly healed with just a small scar remaining. Which statement describes what will happen next?
A. Each one of the individual cells near the wound will grow in size to cover the injured part.
B. Cells will be transported from distant areas to the wound to cover the injured area.
C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.
D. A material will be released by the injured cells that will cover the wound and repair the cells.
Answers
Answer:
c
Explanation:
The wound will be healed by the production of new cells near the wound by the cell replication process and the therefore the identical cells are produced by the mitosis to repair the damaged tissues.
Note the below points about mitosis;
The mitosis is a process in which the cell replication occurs.In mitosis, the single parent cell is divided into two identical daughter cells by the process of cell division, it takes by time.The mitosis involves the healing of wound, growth of the organisms, replacement of the worn out cells.Thus, mitosis is the process involved in the healing of wound in living beings.
Therefore, we can say that the answer of the question is C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.

Calculate the mass of 5.22 mol of He.
Answers
Answer:
The mass is 20, 89 grams of He.
Explanation:
We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g

The mass of 5.22 mol of He will be 20.84 grams.
We have 5.22 mol of He.
We have to calculate its Mass.
Which element is represented by symbol He ?Helium is a chemical element with the symbol He and atomic number 2. It is a gas which is colorless, odorless, tasteless, non-toxic, inert and monatomic.
According to the question -
Number of moles of Helium = 5.22 mol
Now, I mole of Helium will have its mass equal to its Atomic weight. Therefore -
Mass of 1 mole of He = 4.002602 g
So, the mass of 5.2 mol of He will be = 5.2 x 4.002602 = 20.84 grams
Hence, the mass of 5.22 mol of He will be 20.84 grams.

Which of the following describes an exothermic reaction?
Answers
An exothermic reaction is described by ΔH(reactants) is greater than ΔH( products) and the correct option is option A.
What is Exothermic reaction?The word exothermic means “releasing heat.” Energy, often in the form of heat, is released as an exothermic reaction proceeds.
Enthalpy of a reaction is defined as the heat energy change (Δ H) that takes place when reactants go to products. If heat is absorbed during the reaction, Δ H is positive; if heat is released, then Δ H is negative.
ΔH value negative –> energy released –> exothermic reaction
ΔH value positive –> energy absorbed –> endothermic reaction
Therefore, an exothermic reaction is described by ΔH(reactants) is greater than ΔH( products) and the correct option is option A.

Answer:
Covalent bonding is a type of chemical bonding which is characterized by atoms sharing electrons. For nitrogen and chlorine to covalently bond, nitrogen needs 3 electrons. Chlorine only has one electron therefore two more chlorine molecules are needed. Because one atom of nitrogen needs 3 atoms of chlorine to bond, the formula will be NCl3.
