ANSWER: 4.5x10^22
EXPLANATION: Because there are 6.022x10^23 atoms per mole; therefore, (6.022x10^23*(0.075)=4.5x10^22 atoms of titanium

Answer:

N(Ti)=0,0940625·10²³ atoms/mol

Explanation:

n=m/M

n(Ti)=0,75/48=0,015625

N=n·NA

N(Ti)=0,015625·6,02·10²³=0,0940625·10²³ atoms/mol

Carbon dioxide in the atmosphere can be reduced by _.*​
pychu [463]

Answer:

As the use of plants as carbon sinks can be undone by events such as wildfires, the long-term reliability of these approaches has been questioned. Carbon dioxide that has been removed from the atmosphere can also be stored in the Earth's crust by injecting it into the subsurface, or in the form of insoluble carbonate salts (mineral sequestration).

PLEASE HELP!!
NARA [144]
We can skip option B and D because NaCl is salt and H₂SO₄ is a strong acid.
Neutralization reactions are those reactions in which acid and base react to form salt and water.
As water being amphoteric in nature can react with HCl as follow,

                           HCl  +  H₂O   ⇆  H₃O⁺  +  OH⁻

In this case no salt is formed, so we can skip this option.

Ammonia being a weak base can abstract proton from HCl as follow,

                              HCl  +  NH₃  →  NH₄Cl

Ammonium Chloride is a salt. So, among all four options, Option-C is the correct answer.

History of Aluminum​
solniwko [45]

Answer:

Aluminium was named after alum, which is called 'alumen' in Latin. This name was given by Humphry Davy, an English chemist, who, in 1808, discovered that aluminium could be produced by electrolytic reduction from alumina (aluminium oxide), but did not manage to prove the theory in practice.
