Why do earthquakes usually occur at plate boundaries?

Chemistry
2 answers:
SCORPION-xisa [38]4 years ago

Answer:

The rock is generally moving along massive cracks in the Earth's crust. These are called faults. Most earthquakes that we know of usually happen at/near the boundaries in between the Earth's tectonic plates. This is because that is where there is mostly a massive concentration of faults. Movement along these faults can also cause earthquakes as well.

I hope this helped :D

Answer:

Earthquakes happen when rock below the Earth's surface moves abruptly. Usually, the rock is moving along large cracks in Earth's crust called faults. Most earthquakes happen at or near the boundaries between Earth's tectonic plates because that's where there is usually a large concentration of faults.

The molecular formular is given as;  C8H9NO2

b. What is the hybridization state of each C, N, and O atom?

From the image attached;

All the carbon atoms in the benzene ring has hybridization of sp2.

The carbon that is doubly bonded (carbonyl) to the oxygen has hybridization of sp2

The last carbon to the right has hybridization of sp3

The hybridization of nitrogen in the compound is sp3 hbridized.

Oxygen atom in alcohol  is sp3 hybridised

Oxgen in the carbonyl group is sp2 hybridized.

6) A rectangular fish tank is 70.00 cm long, 300.00 mm wide, and 300.00 m deep.
KATRIN_1 [288]

Answer:

Volume of water it can hold 63000,000 cm³

Mass of water is 63000,000 g.

Explanation:

Given data:

Length of tank  = 70.00 cm

Width of tank = 300.00 mm

Height of tank = 300.00 m

Volume of water it can hold  = ?

Mass of water = ?

Solution:

First of all we will convert the units into same unit.

Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm

Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm

Volume of water it can hold:

V = l×w×h

V = 70.00 cm × 30 cm × 30000 cm

V = 63000,000 cm³

Mass of water:

Density of water from literature = 1 g/cm³

d = m/v

1 g/cm³ = m/ 63000,000 cm³

m = 63000,000 g

A cube of plastic 1.2x10^-5 km on a side has a mass of 1.1 g. what is its density in g/cm^3
Vesna [10]
Length of 1 side 1.2*10^-5km =1.2*10^-5*10^5 =1.2cm 

<span>volume of the cube (1.2)^3=1.728 cm^3 </span>

<span>density= mass/volume= 1.1/1.728=0.636 g/cm^3</span>
