Your answer would be boiling water because it creates stem and stem is pressure i hope this helps
Answer:
B. compound
Explanation:
A pure substance can be an element, which consists of only one type of atom and cannot be broken down by a chemical change, or a compound, which consists of two or more types of atoms.
A.) The conversion factor is 1 amu =

grams of neutrons:
=1.00811 amu
b.) The mass in grams of one lithium ion which has an atomic weight of 6.94 amu.
=
c.) How many amu in 6.492x10^-23g potassium?
= 39.0957 amu
Answer:
1 mol Al. 26.9815 g Al. ×. 2 mol AlCl. 3. 2 mol Al. =0.100 mol AlCl3. The balanced equation says: 3 mol Cl2 produces ... that the initial mass of Al was larger than required to react with all of the Cl2. The sum of the masses.

Answer:
83 g
Explanation:
Step 1: Write the balanced equation
2 Fe + 3 S ⇒ Fe₂S₃
Step 2: Calculate the moles corresponding to 95 g of Fe
The molar mass of Fe is 55.85 g/mol.
95 g × 1 mol/55.85 g = 1.7 mol
Step 3: Calculate the moles of S needed to react with 1.7 moles of Fe
The molar ratio of Fe to S is 2:3. The moles of S needed are 3/2 × 1.7 mol = 2.6 mol
Step 4: Calculate the mass corresponding to 2.6 moles of S
The molar mass of S is 32.07 g/mol.
2.6 mol × 32.07 g/mol = 83 g
