Hot spot volcano is the type of volcano which is formed at a weak spot in
the middle of a plate.
Hot spot volcano is an area in the Earth crust which is characterized by large
amount of heat flow in the area due to the volcanic activity. Hot spot
volcano is formed at the middle of the plate as against junctures in which
other types are formed.
The weak spot is what gives rise to the unusual heat flow which makes hot
spot volcano most appropriate.

Find the density of an 8 gram rock if the water in a graduated cylinder rises from 25.0 mL to
29.0 mL when the rock is placed in to the graduated cylinder.
To measure the density of the stone placed in a graduated cylinder let us follow these steps bellow
Measure the volume of water poured into a graduated cylinderPlace the object in the water and remeasure the volume. The difference between the two volume measurements is the volume of the object. Divide the mass by the volume to calculate the density of the object.We know that the formula for density is given as
Given data
Mass = 8gram
Initial Volume of water in cylinder = 25mL
Final Volume of water in cylinder = 29mL
Hence the volume of the rock = 29-25 = 4mL
Therefore the density of the rock = 8/4 = 2 g/mL

This question is describing a thoroughly opened statement about the length of a three as 18 meters, which in the context of science can be referred to:
- A hypothesis or a result in the scientific method, if one is measuring the length of given objects.
- A measurement, if one is measuring the length of a three or any other object.
In both cases, we can note that the measurement has the following basic structure:
1. A number, defining how large or small the measurement is.
2. A unit, defining the system in which the measurement is reported to the scientific community.

determine the bond type (NP, Polar, Ionic)
Answer:
a. NP
b. NP
c. Polar
d. Ionic
e. Polar
Explanation:
The way I did it was using the electronegativity of the elements mentioned and subtracted the pairs. For non polar the difference is 0-0.4, for polar it’s 0.4-2.0, for ionic it’s >2.0. I included the chart I used to find the electonegativity for the elements below.
B: 2.04, P: 2.19, difference is 0.15, so NP
Be: 1.57, Si: 1.9, difference is 0.33, so NP
C: 2.55, Na: 0.93, difference is 1.62, so Polar
Li: 0.98, O: 3.44, difference is 2.46, so Ionic
Mg: 1.31, N: 3.04, difference is 1.73, so Polar
If you really want I can explain why electronegativity affects the types of bonds, just comment below

Polar is the correct answer

A 0.03 mol sample of NH4NO3 (s) is placed in a 1 L evacuated flask, which is then sealed and heated. The NH4NO3 (s) decomposes completely according to the balanced equation above. The total pressure in the flask measured at 400 K is closest to which of the following? (The value of the gas constant, R, is 0.082 L atm mol-1 K-1.)
a. 3 atm
b. 1 atm
c. 0.5 atm
d. 0.1 atm
e. 0.03 atm
The total pressure in the flask measured at 400 K is 1 atm
The correct answer to the question is Option B. 1 atm
From the question given above, the following data were obtained:
Number of mole (n) = 0.03 mole Volume (V) = 1 L Temperature (T) = 400 KGas constant (R) = 0.082 atm.L/Kmol Pressure (P) =?Using the ideal gas equation, we can obtain the pressure in the flask as follow:
PV = nRT
P × 1 = 0.03 × 0.082 × 400
P = 1 atmTherefore, the total pressure in the flask measured at 400 K is 1 atm

Answer: a: 3 atm
Explanation:
0.03 mol NH4NO3 decomposes into 0.09 mol of gas total, thus we multiply 0.09 by 0.082 and 400K to get our answer of about 3 atm.
