Answer:
34.92 grams NaCl (in 1 L of solution)
Explanation:
The chemical formula of sodium chloride is NaCl. From the formula, we can calculate the molar mass of NaCl:
MM(NaCl)= MM(Na) + MM(Cl) = 23 g/mol + 35.4 g/mol = 58.4 g/mol
A solution of NaCl with a molarity of 0.598 M has 0.598 moles of NaCl per liter of solution. So, we multiply the moles by the molar mass of NaCl to calculate the mass we need:
mass of NaCl = 0.598 mol x 58.4 g/mol = 34.92 g NaCl
Therefore, we need 34.92 grams of NaCl to prepare 1 liter of a solution with a molarity of 0.598 M.
Answer:
the reaction is exothermic
Explanation:
heat will be produced from the reaction
Answer:
There are 4 single bonds and 2 double bonds.
Explanation:
Sulfur atom has six electrons in its outermost shell which can participate in bonding and hence it will form six bonds in total.The chemical formula of sulfuric acid is given by 
.In sulfuric acid we have four oxygen atoms and two hydrogen atoms.
Sulfur atom is bonded directly to all the four oxygen atoms out of which two are double bonds.The single-bonded oxygen atoms are inturn bonded to the two hydrogen atoms.
The above statements will make sense after you go through the figure given below.
Hence it has four single bonds and two double bonds.(counting only those bonds in which sulfur is involved)
It’s going to be cooler because it over night
The hydrogen bonds between molecules of hydrogen peroxide loosen as temperature rises toward the optimal point, facilitating catalase's reaction with the molecules. The enzyme denatures and its structure is affected if the temperature rises above the ideal level.
<h3>What is a catalase?</h3>
The catalase is an enzyme that is responsible for reducing hydrogen peroxide.
<h3>What does catalase do?</h3>
- This enzyme is in charge of neutralizing hydrogen peroxide through its breakdown
- It hence preserves an ideal level of the molecule in the cell that is also necessary for cellular signaling processes
<h3>Importance of catalase enzyme:</h3>
- Almost every organism that is exposed to oxygen contains the very common enzyme catalase.
- In order to prevent oxidative damage, which can happen when cells or other molecules in the body come into contact with oxidative chemicals, catalase serves as a protective barrier in live cells.
