Hi , the answer is silicon.
Answer:
D) single replacement
Explanation:
Given reaction:
Mg + 2HCl → MgCl₂ + H₂
The reaction shown above is a single displacement reaction.
In a single displacement reaction, a more reactive atom displaces another from a given compound.
The comparison here is between Mg and H.
On the activity series, Mg is higher and more reactive, it will displace H from the solution of HCl. This
This reaction type is called a single replacement reaction.
Hey there!:
Density = 0.798 g/mL
Volume = 16.9 mL
Therefore:
Mass = density * volume
Mass = 0.798 * 16.9
Mass = 13.4862 g
6.5 is slightly acidic - so the answer is B.
This is due to 7 being neutral
7-14 is basic
0-7 is acidic
Answer:
0.3477 grams
The conversion factor is 1/1000
Explanation:
347.7 mg = 0.3477 grams
1 mg = 1x10⁻³ g
1 g / 1000 mg . 347.7 mg = 0.3477 grams
