Answer:
1.59 atm
Explanation:
The reaction is:
The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:
we don't include because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of is:
from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of .
The partial pressure of each gas is:
so total pressure is:
replacing the moles we get:
We know that T2=3*T1
replacing this value in the equation we get:
Answer:
A. ions with opposite charges
Explanation:
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

Answer:
Latitude:
Longitude:
Explanation:
Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:
Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.
In this sense latitude refers to the equatorial line that divides the Earth in two hemispheres (North and South).
Longitude represents the specific east–west position of a point on the Earth's surface, being longitude the prime meridian or Greenwich meridian.
So, according to the figure, where the model of the Earth is divided by latitude lines separated by and the longitude lines separated by ; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.
Hence, point A location is:
Latitude:
Longitude:
Answer:
B) sand
Explanation:
A) Oil is a wrong choice because it is a liquid not a solid and also if it is oil, it will float over the water surface as a droplets.
B) Sand is the right choice, because sand is a solid and it does not dissolve in water and stabilizes at the bottom.
C) Sugar is a wrong choice, because small amount of sugar will dissolve in water and be a homogeneous solution and does not appear as a particles.
D) Wood ships is also a wrong choice, even it is a solid and does not dissolve in water, but it will float over the water surface.
