Explanation:
By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...
1 mole of hydrogen atoms (H) = 1.00794 grams
1 mole of molecular hydrogen (H₂) = 2.01588 grams
1 mole of any substance = 1 formula weight in grams
1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams
In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.
For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...
Given N₂(g) + 3H₂(g) => 2NH₃(g) is assumed to be at 0°C; 1 Atm pressure.
Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)
Molecular Hydrogen = 3 molar volumes = 3 x 22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)
Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃
Question
<em>which cell living organism are diploid?</em>
Answer:
<em>Ploidy is the area of biology that refers to the number of chromosomes in a cell. Therefore, cells with two sets are diploid, and those with one set are haploid. In diploid organisms, such as humans, the haploid cells are used only for the sex cells for reproduction, while the rest of the cells are diploid.</em>
Hope this helps!
Answer:
Gene is the basic unit of inheritance.
There are two meanings to the word "Distal"
Anatomy
- situated away from the center of the body or from the point of attachment.
Geology
2. relating to or denoting the outer part of an area affected by geological activity.
B. because the little number below the H stands for how many atoms there are, and b has 1 more Hydrogen atom than A does.
