Answer:
66.0 mL HClO3
Explanation:
M1V1 = M2V2
M1 = 0.100 M HClO3
V1 = ?
M2 = 0.165 M KOH
V2 = 40.0 mL KOH
Solve for V1 --> V1 = M2V2/M1
V1 = (0.165 M)(40.0 mL) / (0.100 M) = 66.0 mL HClO3
Answer:
Covalent bonding
Explanation:
Covalent bonding is the bond that holds all compound that are formed by carbon.
It is a very strong intermolecular bond that holds the structure of carbon compounds in place.
Principally, covalent compounds are formed by sharing of electrons between contributing atoms.
Covalent bonds are the strongest bond types. A reason for this conclusion can be see in case of diamond. Here, there is a covalent linkage between the atoms present and the strength of these bonds is responsible for how strong the diamond crystal is
hi
i did not understood ur question pls clarify and say
bye
Answer:
Bq/m3 (becquerels per cubic meter) or pCi/l (picocuries per litre)
Explanation:
The unit of the International System of Units identified to measure radioactive activity is Becquerelio (Bq) and equivalent to one decay per second.
The Curio (Ci) is also a radioactivity unit, which is still being used in some countries. It owes its name to chemists and chemists Pierre and Marie Curie.
It represents the amount of material in which 3.7 × 1010 atoms per second, or 3.7 × 1010 nuclear decays per second, which is roughly the activity of 1 g of 226Ra (isotope of the chemical chemical element).
The equivalence between the two is:
1Ci= 3,7 × 1010Bq
The specific radioactive activity of a radioactive gas such as radon gas is measured per unit volume and measured in Bq/m3 or pCi/l.
In this case the equivalence is:
1pCi/l= 37Bq/m3
