The mass of titanium is = 47,867 g/1mol
Applying the rule of avrogado
1mol _______ 6,023 × 10^(23) at
0,075mol ___ x
X . 1mol = 0,075mol . 6,023 . 10^(23)at
X = 0,075 . 6,023 . 10^(23) at
X = 4,51 . 10^(22) atoms
Hope this helps
The correct answer is (3)
I-131 and P-32
The explanation:
according to attached table:
- we can see that the half life of p 32 is 14.28d (more than one hour)
- and the half life of I-131 is 8.021 d
(more than one hour)
and They both have β- decay mode and with half-lives greater than hour.
The answer is True . The precision of a measuring is based on the fitness of its scale subdivisions
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.
![AB\rightarrow A+B](https://tex.z-dn.net/?f=AB%5Crightarrow%20A%2BB)
Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.
![AB+CD\rightarrow AD+CB](https://tex.z-dn.net/?f=AB%2BCD%5Crightarrow%20AD%2BCB)
Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.
![A+B\rightarrow AB](https://tex.z-dn.net/?f=A%2BB%5Crightarrow%20AB)
Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.
![A+BC\rightarrow AC+B](https://tex.z-dn.net/?f=A%2BBC%5Crightarrow%20AC%2BB)
In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has
as a component.
The reaction between HCl and
is a type of neutralization reaction and it is a type of double displacement reaction.
The equation between the two follows:
![CaCO_3+HCl\rightarrow CaCl_2+H_2O+CO_2](https://tex.z-dn.net/?f=CaCO_3%2BHCl%5Crightarrow%20CaCl_2%2BH_2O%2BCO_2)
Hence, the correct answer is Option B.
