Answer:
1. LiCi is formed by the treatment of lithium carbonate with hydrochloric acid
2. A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
3. Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity into two or more fragments.
4. A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound
5. Double replacement reactions have two ionic compounds that are exchanging anions or cations.
6. The most electronegative elements are found on the top right of the periodic table.
7. cesium
8. Electronegativity describes the degree to which an atom attracts electrons in a chemical bond. But the electronegativity of two atoms would determine their bond type.
9. ionic bond
10. polar covalent bond
11. fluorine
12. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change.
Hope i was able to help!!!
Answer :
Explanation :
The aluminium and fluorine react to give ionic compound aluminium fluoride.
Aluminium has 1 valence electrons in their shell and fluorine has 7 valence electrons in their shell.
For the complete octet, both aluminium and fluorine exchange valence electrons to form an ionic compound.
The aluminium donates its three valence electrons to three fluorine atoms and they form one
and three
ions.
Electron transfer image is shown below.
<span>The correct answer is ideal gas law.
when the ideal gas law formula is:
PV = nRT ,
when P is the pressure.
V is the volume.
and R is the ideal gas constant.
T is the temperature.
and n is the number of moles.
So, this is the law which relates pressure, temperature, volume and number of moles . and this law state that 1 mole of an ideal gas will occupy a volume V = 22.4 L</span>

1) 17.5 mL
Explanation:
Hello,
In this case, the reaction between sulfuric acid and potassium hydroxide is:
![H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O](https://tex.z-dn.net/?f=H_2SO_4%2B2KOH%5Crightarrow%20K_2SO_4%2B2H_2O)
In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:
![2*n_{acid}=n_{base}](https://tex.z-dn.net/?f=2%2An_%7Bacid%7D%3Dn_%7Bbase%7D)
And in terms of concentrations and volumes:
![2*M_{acid}V_{acid}=M_{base}V_{base}](https://tex.z-dn.net/?f=2%2AM_%7Bacid%7DV_%7Bacid%7D%3DM_%7Bbase%7DV_%7Bbase%7D)
Thus, we solve for the volume of acid:
![V_{acid}=\frac{M_{base}V_{base}}{2*M_{acid}} =\frac{35mL*1.5M}{2*1.5M} \\\\V_{acid}=17.5mL](https://tex.z-dn.net/?f=V_%7Bacid%7D%3D%5Cfrac%7BM_%7Bbase%7DV_%7Bbase%7D%7D%7B2%2AM_%7Bacid%7D%7D%20%3D%5Cfrac%7B35mL%2A1.5M%7D%7B2%2A1.5M%7D%20%5C%5C%5C%5CV_%7Bacid%7D%3D17.5mL)
Best regards.
