The answer to the question is "B. Roman Numerals"
In order to transfer liquid we need
a) a funnel: an apparatus which transfers liquid from one glassware to other (of narrow mouth) without spilling
b) We should use a beaker (a glassware with a beak for proper transfer) to transfer liquid from it to other glass apparatus.
c) other things are like transparent clear dry and clean apparatus should be used

Answer:
molarity = 0.385 moles/kg
Explanation:
Assume that the volume of the aqueous solution given is 1 liter = 1000 ml
Now, density can be calculated using the following rule:
density = mass / volume
Therefore:
mass = density * volume = 1.23 * 1000 = 1230 grams
Now, 0.467 m/L * 1L = 0.467 moles of HCl
We will get the mass of the 0.467 moles of HCl as follows:
mass = molar mass * number of moles = (1+35.5)*0.467 = 17.0455 grams
Now, we have the mass of the solution (water + HCl) calculated as 1230 grams and the mass of the HCl calculated as 17.0455 grams. We can use this information to get the mass of water as follows:
mass of water = 1230 - 17.0455 = 1212.9545 grams
Finally, we will get the molarity as follows:
molarity = number of moles of solute / kg of solution
molarity = (0.467) / (1212.9594*10^-3)
molarity = 0.385 mole/kg
Hope this helps :)
Answer:
NH3
Explanation:
The "tri" attached to the trihydride means 3. So your hydrogen is going to have 3 atoms.
