Answer:

1) eathquake

earthquake is the natural calamities where there is the vertical and horizontal shaking of the

earth crust. it is cause due to overlappibg of the different plates that are present in the earth surface. when this plates intersect or expand the earth occurs

consequences are it causes loss of life and human property , degards the environment , it leads to flood, landslides etc The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction.

Next - volcanic eruption

its is the out flow of the larva from the inner of the earth to other surface. it is cayse due to high pressure exerted on the surface of the earth that leads to explode the inner larva.

its consequences are it degards the environment and loss of the beauty of the nature , there is loss of human life , widlife , etc. volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash. When warnings are heeded, the chances of adverse health effects from a volcanic eruption are very low.

Elements can be described by various properties, and identified by their boiling and melting points. For example, gold melts at 1,064ºC and boils at 2,856ºC. Does boiling point depend on the mass present?

A. No; chemical properties stay the same regardless of mass.

B. No; physical properties stay the same regardless of mass.

C. Yes; physical properties can change when mass increases or decreases.

D. No; qualitative properties like boiling point stay the same regardless of mass.

What is the volume of a 5M solution with that has 16.5 moles?
kenny6666 [7]
Molarity can be used to calculate the volume of solvent or the amount of solute. The relationship between two solutions with the same amount of moles of solute can be represented by the formula c1V1 = c2V2, where c is concentration and V is volume.

Calculate the standard potential for the following galvanic cell: Ni(s) | Ni2+(aq) || Ag+(aq) | Ag(s) which has the overall bala
mylen [45]

Answer:

1.06  V  

Explanation:

The standard reduction potentials are:

Ag^+/Ag     E° =  0.7996 V  

Ni^2+/Ni     E° = -0.257   V

The half-cell and cell reactions for Ni | Ni^2+ || Ag^+ | Ag are

Ni → Ni^2+ + 2e-                     E° = 0.257   V

<u>2Ag^+ 2e- → 2Ag               </u>    <u>E° = 0.7996 V </u>

Ni + 2Ag^+ → Ni^2+ + 2Ag     E° = 1.0566  V

To three significant figures, the standard potential for the cell is 1.06 V .

How many atoms are in 20.6 moles of curium
Harman [31]

Answer: 1.24 × 10^25

Explanation:

\frac{20.6 moles}{1} × \frac{6.022 * 10^{24} }{1 Mole}

Using our knowledge in unit conversions, we know the mole units cancel each other out and all there's left is the atom unit. From here we can multiply the fractions and eventually we end with the number 124.0532 × 10^23

According to the scientific notation rules, the number to the left of the decimal cannot exceed 10 so we have to move the decimal to the left two spaces. With this change, we also have to change the exponent of the 10. Because we moved the decimal point two spaces to the left, that means we have 10^25.
