Hi,
To solve the question, first of all we will find out the no. of moles of H2SO4 in 19 g of sulfuric acid.
As we know:
No . of moles = Mass/ Molar mass
No. of moles= 19 g/98.08
g
No. of moles= 0.1937
Now we know the no of moles of H2SO4 that will react with 2LiOH. We also know the molar equivalence of H2SO4 , and 2LiOH that will react.
So, the water that will be produced will be 2H2O and 1 Li2SO4 when H2SO4 that will react with 2LiOH.
0.1937 x 2x 18.01
=6.977
=6.98
Therefore, approximately 6.98 grams of water will be produced from 19 g of sulfuric acid.
Hope it helps!
The answers to this problem is C
The cellular macromolecules that are referred by the description above are the LIPIDS. The complement pathway system is a constituent of the natural immunity and this provides us a natural defense against infection. In the complement pathway of the immune system, the macromolecules that make this up are the lipids.
Answer:
ions
Explanation:
An atom that has gained or lost an electron is called an ion. Ions are charged particles that have lost or added an electron to their outermost shell. Ions are the basis of any chemical reaction. The combination of ions leads to the formation of bonds between atoms and this results in molecules and compounds.
When atoms are in their ground state, they are otherwise neutral and such would not combine chemically. It is difficult to find elements in such form naturally. Atoms that have ionized by losing or gaining electrons would freely combine with one another in order to establish a more stable configuration.
A. Compound that has the highest solubility in pure water is caso4, ksp = 2. 4 x 10-5
More about CASO4:
The inorganic chemical with the formula CaSO4 and its associated hydrates are known as calcium sulphate (sometimes known as calcium sulphate). It serves as a desiccant in the form of -anhydrite (the anhydrous form).
Another hydrate is found naturally as the mineral gypsum, while one is more commonly known as plaster of Paris. It is employed widely in industries. Each form is a white solid that has a low water solubility. Water becomes permanently hard due to calcium sulphate.
CaSo4 is mostly used to produce plaster of Paris and stucco.
