Answer: d)
and
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water. The
ions from water reacts with
ions from base to give water.

The answer I would choose is the third one
Answer:
![m_{HgCl_2}=42.7gHgCl_2](https://tex.z-dn.net/?f=m_%7BHgCl_2%7D%3D42.7gHgCl_2)
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
![HgSO_4+2NaCl\rightarrow HgCl_2+Na_2SO_4](https://tex.z-dn.net/?f=HgSO_4%2B2NaCl%5Crightarrow%20HgCl_2%2BNa_2SO_4)
In such a way, the mercury II sulfate (molar mass 296.65g/mol) is in a 1:1 molar ratio with the mercury II chloride (molar mass 271.52g/mol), for that reason the stoichiometry to find mass in grams of mercury II chloride turns out:
![m_{HgCl_2}=46.6gHgSO_4*\frac{1molHgSO_4}{296.65 gHgSO_4}*\frac{1molHgCl_2}{1molHgSO_4} *\frac{271.52gHgCl_2}{1molHgCl_2} \\\\m_{HgCl_2}=42.7gHgCl_2](https://tex.z-dn.net/?f=m_%7BHgCl_2%7D%3D46.6gHgSO_4%2A%5Cfrac%7B1molHgSO_4%7D%7B296.65%20gHgSO_4%7D%2A%5Cfrac%7B1molHgCl_2%7D%7B1molHgSO_4%7D%20%2A%5Cfrac%7B271.52gHgCl_2%7D%7B1molHgCl_2%7D%20%5C%5C%5C%5Cm_%7BHgCl_2%7D%3D42.7gHgCl_2)
Best regards.
Answer: The author used the word "conversely" because the first statement he made is in CONTRAST to the second statement he made.
Explanation:
Matter is made up of atoms or molecules that are in constant motion. The motion of these tiny particles ( molecules) gives the object energy. The movement of these molecules depends on the state of matter which includes
--> GASEOUS STATE: Here, the particles are completely free to move and are always in motion.
--> LIQUID STATE: particles in this state slide by one another and are always in motion.
--> SOLID STATE: particles in this state are held tightly together but are always in motion.
Also, the molecules in motion are greatly affected by temperature changes. Increase in temperature will cause the particles in the liquid to move faster. Such is seen when soup is heated, the molecules travel faster than before. But the OPPOSITE is seen in an ice cube. This is because the ice cube is in solid state and of a lower temperature.
A I’m sure of it because it only makes since one would think ✊
