Answer:
may be...... false not sure
Explanation:
The theoretical yield is 160 g H₂O.
<em>Moles of H₂</em> = 18 g H₂ × (1 mol H₂/2.016 g H₂) = 8.93 mol H₂
<em>Moles of H₂O</em> = 8.93 mol H₂O × (2 mol H₂O/2 mol H₂) = 8.93 mol H₂O
<em>Theoretical yield</em> of H₂O = 8.93 mol H₂O × (18.02 g H₂O/1 mol H₂) = 160 g H₂O
Answer with Explanation:
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits. Since human cells carry two copies of each chromosome they have two versions of each gene.
A chemical property of isopropanol : D. Isopropanol is flammable.
<h3>Further explanation
</h3>
There are changes that occur in the mater: physical changes and chemical changes
Classification uses the principle of the initial and final state of the substance.
Physical changes do not form new substances, so the properties of the particles remain the same.(size,volume,shape)
Example : boiling and freezing, just change its phase form from liquid to gas or from liquid to solid
Chemical changes/reaction form new substances(products) that are different from the initial substances(reactants)
Example : toxic, corroded
So :
-
the physical properties of isopropanol :
<em>mass, density, evaporation</em>
- the chemical properties of isopropanol :
<em>highly flammable</em>
The valence electron determines whether an ionic or covalent bond develops between two atoms.
An atom's outer shell electrons, known as valence electrons, can take a role in the creation of chemical bonds. When two atoms establish a single covalent bond, normally, both atoms contribute one valence electron to create a shared pair.
Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When one atom's valence (outermost) electrons are permanently transferred to another atom, a bond of this kind is created. The one or two and three are lost and gained in ionic bond formation, but particles with four valence electrons are neither lost nor gained. The four electrons are generally shared to form a covalent bond.
Hence, the valence electron decides the type of the bond.
