The International Bureau of Weights and Measures is the society that scientist form to bring about one universal system of measurements.
<u>Explanation:</u>
Every theoretical assumptions should be proved experimentally and for that we need a specific system to measure or quantify parameters used in those experiments or the outcome results variables.
The measurements of length should be done by measuring them in meters only and not by liters. The physical properties of every materials should have a particular way of measuring them and this is decided by the International Bureau of Weights and Measures.
They also decide the units of each measurements and the standardization of each units and weights are also done by this society.
Answer:
I₂ + H₂O --------→ HI + HIO
Explanation:
Iodine is not fully dissolve in water but only dissolve up to some extent.
When iodine was mixed with water it give mixture of two products.
- Hydrogen iodide or hydroiodic acid (HI)
- Hypoiodous acid (HIO)
So the balance reaction is as under
I₂ + H₂O --------→ HI + HIO
All the reactant are one mole and one one mole of each product produced in the shown reaction.
This is a reversible reaction and only 0.05% of Iodine molecule react with water and the other Iodine molecule remain in water unreacted.
Answer:
2.64 × 10⁶ g
Explanation:
We can find the mass of air using the ideal gas equation.
where,
P is the pressure (P = 1.00 atm)
V is the volume (V = 2.95 × 10⁶ L)
n is the number of moles
R is the ideal gas constant (0.08206atm.L/mol.K)
T is the absolute temperature (121°C + 273 = 394 K)
m is the mass
M is the molar mass (28.09 g/mol)
I do not believe there is a answer for this. However i could be wrong.
Answer:
The answer is true
Explanation:
This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move "uphill," from regions of lower to higher concentration. This process is called active transport, and requires some form of chemical energy.
