What is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K?
Answer:
12.3
Explanation:
Trust
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 12.3L is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. There is no force of attraction between the particles.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of oxygen gas= 2.00 atm
V= volume of oxygen gas =?
n =number of moles of oxygen gas=1.00 mol
T =temperature of oxygen gas =300.0 K
R = Gas constant = 0.0821 L.atm/K.mol
Substituting all the given values, we get
2.00×V=1× 0.0821×300.0
On calculation we get
Volume=12.3L
Therefore, the volume of oxygen is 12.3L.

The density of mercury is 13.6 g/mL. What is the mass of 3,426 mL of mercury?
Answer:
m = 46593.6 g
Explanation:
Given data:
Mass of mercury = ?
Volume of mercury = 3426 mL
Density of mercury = 13.6 g/mL
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
13.6 g/mL = m/ 3426 mL
m = 13.6 g/mL × 3426 mL
m = 46593.6 g

What does the formula of an ionic compound tell you?
Answer:
The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each.
Explanation:
what charged particle is produced during ionic bonds
Answer:
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation or a positively charged ion. The atom gaining one or more electrons becomes an anion which is a negatively charged ion.
The compound has the empirical formula of CH. Give some possible molecular formulas for this compound if you didn't know the molar mass.
Answer:
Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.
Explanation:
The result is the molecular formula

How is the rock in the deep mantle similar to the rock in the parts of the mantle nearest the surface? How is it different?
Answer:
Similarity: Rocks within the mantle contain more magnesium and iron than the ones in the crust.
Difference: Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly. On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
Explanation:
Rocks within the mantle contain more magnesium and iron than the ones in the crust.
What is Rocks?
Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly.
On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
According to geologists, a rock is a naturally occurring material made up of crystalline crystals of various minerals that have fused together to form a solid mass.
Therefore, Rocks within the mantle contain more magnesium and iron than the ones in the crust.

what is the mass of the atom
Answer:
19
Explanation:
The mass of an atom is given by its mass number. This is because the mass of an atom is concentrated at the nucleus.
Mass number = number of protons + number of neutrons
Protons and neutrons are the most massive particles in any atom.
Protons are the positively charged particles in an atom
Neutrons are uncharged particles.
So, the mass number of this atom is:
Mass number = 9 + 10 = 19
