Which of the following best defines base isolation?(1 point)

Base isolation is a technique used by engineers to help prevent damage to buildings by volcanoes. The main structure of the building is separate from the base, which allows lava to pass under the building without causing much damage.

Base isolation is a technique used to prevent large-scale damage from volcanoes. New communities being built are set as far back as possible from the base of a volcano.

Base isolation is a technique used to prevent damage to buildings during tsunamis. The main structure of the building is separate from the base, which allows water to pass beneath buildings without causing much damage.

Base isolation is a technique used by engineers to help prevent damage to buildings by earthquakes. The main structure of the building is separate from the base and sits on a bed of springs.

Explanation:

[tex]\to C_6H_9NO[/tex]

calculating the HOI:

[tex]= \frac{2C+2+N-H-X}{2} \\\\ =\frac{2\times 6+2+1-9-0}{2}\\\\ =\frac{12-6}{2}\\\\=\frac{6}{2}\\\\=3[/tex]

So, in the above compund there are three bounds or we can say that one is double and two bound is single.

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

hope this helps also can i get brainliest

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.

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.

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.

Explanation:

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.

Answer:

Because the equilibrium constant is only at constant at temperature. Changing the temperature changes the Ka.

Explanation:

An exothermic reaction is described by ΔH(reactants) is greater than ΔH( products) and the correct option is option A.

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.
