the force of attraction of iron fillings towards magnet
Answer:
Option D. ZnCl₂ and H₂
Explanation:
From the question given above, the following equation was obtained:
2HCl + Zn —> ZnCl₂ + H₂
Products =?
In a chemical equation, reactants are located on the left side while products are located on the right side i.e
Reactants —> Products
Now, considering the equation from the question i.e
2HCl + Zn —> ZnCl₂ + H₂
The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.
Thus, option D gives the correct answer to the question.
In ionic bonds electrons are transferred from one species to another and the electrostatic attraction between oppositely charged ions gives rise to the ionic bond.
covalent bonds are when electrons are shared between 2 atoms.
the electronegativity difference between the atoms taking part in the bond will decide if its an ionic bond or covalent bond.
if the electronegativity difference is very large then ionic bond is formed. if the electronegativity difference is very low then covalent bond is formed
the electronegativity difference between H and S is very small therefore they form a covalent bond by sharing their electrons
correct answer is
2) electrons are shared to form a covalent bond
Answer:
The answer is RNA
Explanation:
Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
Answer:
c
Explanation:
The number of jobs in renewable energy worldwide increased in 2020, despite the huge economic disruptions caused by the pandemic, with the growing industry holding up better than fossil fuels. so which means reasourses are limited because of the pandemic and prises on thing rising.
