10 protons since it’s equal to the atomic number. 10 neutrons given that it’s mass number - proton number. Protons and electrons are equal so 10 electrons
answer: A thorium has 90 protons
Answer:
HF hydrofluoric acid
Ca(OH)2 calcium hydroxide
CaF2 calcium fluoride
Explanation:
Hello!
In a neutralization reaction an acid reacts with a base forming a salt plus water.
2 HF + Ca(OH)2 --> CaF2 + 2 H2O
Successes with your homework!
A pH of 7 is neutral in terms of acidity, it means the substance is neither basic nor acidic. A pH above 7 indicates a basic solution, while a pH below 7 indicates acidiity. If a weak base react with a strong acid, the strong acid will release more H⁺ ions than the OH⁻ ions released by the weak base, which means the salt will be acidic, or will have a pH below 7.
The best answer is 2.0
Answer:
B - End to end overlap of p overlap
Explanation:
Sigma bonds (σ bonds) are the strongest type of covalent chemical bondSigma bonds are formed by end-to-end overlapping. Sigma bonds can occur between any kind of atomic orbitals;The combination of overlapping orbitals can be s-s, s-pz or pz-pz.
