Answer:
heating makes the alcohol molecules of the liquid move faster.
Magnesium plus chlorine equals to magnesium chloride
Answer:
Calcium carbonate
Explanation:
Ionic compounds that tend to have one or more polyatomic ions are the ones that tend to exhibit both ionic and covalent bonding. The only one that meets this is calcium carbonate.
Answer: There are 0.024 moles of gas are present in the container.
Explanation:
Given: Temperature =
= (25 + 273) K = 298 K
Pressure = 1.7 atm
Volume = 345 mL (1 mL = 0.001 L) = 0.345 L
Formula used is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T= temperature
Substitute the values into above formula as follows.

Thus, we can conclude that there are 0.024 moles of gas are present in the container.
Hey there!
Your answer is B. MgCl.
This is because this isn't an actual existing compound.
Water (H₂O) and magnesium chloride (MgCl₂) are both real compounds, but the number of electrons does not line up to make MgCl possible.
Hope this helps!
