Answer:
4 liters
Explanation:
In order to get the answer you just need to multiply the volume amount by 100.
[tex]0.01 \times 100 = 1[/tex]
0.01HL = 1 L
0.01 4HL = 4L

The element oregano is most similar to which element in our periodic table
To determine the most similar element identify the atomic number of the element and other properties such as state of the matter, color, conductivity, or boiling point.
In the period table, elements are arranged based on two main factors:
Their atomic number or the number of protons: This means the first element has the lowest atomic number (1) and the last element Ogannesson has the highest atomic number (118).Their properties such as conductivity, boiling point, among others: Elements are organized in sub-groups such as metals, halogens, etc. based on their elements.Now, if you know both the atomic number or the properties you can determine which element is the most similar to the element that you have.
Note: This question is incomplete because there is no information bout the element "oregano"; due to this, I answered it based on general knowledge.

Type the formula "H2" into the Reactants box. What is the molar mass of hydrogen gas, H2?
The molar mass of hydrogen gas H₂ is 2.016 grams.
What is molar mass?The mass of a substance divided by its concentration, expressed in grams per mole (g/mol), is known as its molar mass.
Mass is the quantity of matter in a physical body. The product of the molar mass of the compound and the moles of the substance are defined as mass.
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
M = m /n
M = molar mass
m = mass of a substance (in grams)
n = number of moles of a substance
The mass of hydrogen is 1
The number of moles of hydrogen is 6.022 x 10²³
Hydrogen gas has a molar mass of 2.016 grams per mole. When two hydrogen atoms join forces to create a molecule with the formula H2, hydrogen gas is created.
Therefore, the molar mass of hydrogen gas H₂ is 2.016 grams

Block A is made of copper, which has a specific heat value of 0.385 J/g*C.
Block B is made of aluminum, which has a specific heat value of 0.900
J/g*C. Both blocks have a mass of 100 grams. If you are trying to heat the
blocks to a temperature of 200 C, which block will need to absorb more
energy?
o Block A (copper) because it has a lower specific heat value.
o Block B (aluminum) because it has a higher specific heat value.
o Block A (copper) because it has a higher specific heat value.
o Block B (aluminum) because it has a lower specific heat value.
Block B will need to absorb more energy as it has higher specific heat value.
What is specific heat?Specific heat is defined as the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius rise. Units of specific heat are calories or joules per gram per degree Celsius.
Specific heat capacity varies with temperature often and is different for each state of matter. While the substance which undergoes phase transition then it's specific heat is technically infinite.
Specific heat of a gas is significantly higher when it is allowed to expand as it is heated .It may also be referred to as a ratio between the specific heat capacities of two substances at a given temperature.It is calculated by the formula ,Q=mcT
For copper, it is 100×0.385×473=18210.5 J
For aluminium ,it is 100×0.90×473=42570 J
As the specific heat of aluminium is higher it will absorb more energy.

What is true of a saturated solution?
Answer:
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.

What will be the new pressure of a gas at 36.0 atm and 108 C if the temperature of the gas is increased to 441 C?
Answer
199 ATM
EXPLANATION
assume that the volume is constant. At higher temp the gas molecules move faster and the pressure goes up.
P=kT
CONVERT C TEMP TO K TEMP FOR GAS PROBLEMS!!!!!!
108C = 108 +273 = 381 K
441C = 441 + 273 = 714K
P=kT
108 =k x 381
K=108/381 = 0.279
AT THE HIGHER TEMP
P =0.279 X 714 =199ATM

Please fill in the blank.
Answer:
Potassium Hydroxide Solution =
or
Potassium Hydroxide =
Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.
As it is in the question, we can map the reactants and product:
Reactants Product
Ammonium Ammonia
Sulfate Sulfate
________ Potassium
________ Water
Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.
This becomes clear when we consider the net ionic equation:
Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water
if we write this a balanced chemical equation:
(NH₄)₂SO₄ + 2KOH → K₂SO₄ + 2NH₃ + 2H₂O
if we write the reaction as an ionic equation
2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O
if we remove the ions that appear on both the reactant and product side (spectator ions)
2NH₄⁺ + 2OH⁻ → + 2NH₃ + 2H₂OHow does the law of conservation of mass apply to this reaction:Mg + 2HCl → H2 + MgCl2?
Answer:
The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

Which ion does it most likely form?
a- Ra2-
b- Ra-
c- Ra2+
d- Ra+
Answer:
The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s
2
It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.
