Answer:
0.2358
Explanation:
We need here apply the law momentum conservation, for objects who collide.
The equation is given by,
Our values are giving by,
We replace in our equation and solve for V_f, then
Therefore their final velocity is -0.2358m/s (Negative symbol only indicate change in the direction)
Mass of cat = 10 lb
1 lb = 0.454 kg
So mass of cat is 4.54 kg
Number of tablets given to cat
Each tablet has 6 mg of drug
Total drug given to cat
Now dose given to cat in mg/kg form
It’s says that the temperature in the room is 23C so the air temperature in the air would be 23C
Answer:
Connection between the sodium and chlorine atoms are Ionic
Explanation:
Ionic bond is defined as the bond formed between two atoms by the complete transferring of electrons. It is type of chemical bond that generates two oppositely charged ions i.e Anion (-ve charge) and cation (+ve charge).
Metals that has 1, 2 or 3 electrons in its valence shell losses valence electrons and become positively charged cation. These electron attracted by the non-metals to form bond and become negatively charged anion. In this way, ionic bond is generated between 2 atoms.
Sodium is a metal with 1 electron in its valence shell. Chlorine is a non-metal with 7 less electrons (need 1 more to complete its valence shell to stabilize) in its valence shell. When sodium comes in contact with chlorine, it losses its one valence electron and become cation with +1 charge. This electron is accepted by chlorine and become anion with -1 charge. In this way ionic bond is formed between sodium and chloride.
Na⁺ + Cl ⁻⇒ NaCl
