1. How many moles of H₂ would be required to produce 9.0 grams of water?
The answer would be approximately 0.4495 moles of H₂.
2. What mass of H₂O is formed when excess H₂ reacts with 64 g of O₂?
A mass of 72g H₂O will be formed.
3.How many moles of SnF₂ will be produced along with 48 grams of H₂?
Approximately 23.811 moles of SnF₂ will be produced.
4. How many moles of sodium are required to produce 40. grams of NaOH?
The answer would be approximately 1.000722 moles of sodium.
I could only answer 4 of them so sorry, I had like check over it.
The last 2 were super confusing for me.

Answer:</h3>
812 kPa
<h3>
Explanation:</h3>
- According to Boyle's law pressure and volume of a fixed mass are inversely proportional at constant absolute temperature.
- Mathematically,
At varying pressure and volume;
P1V1=P2V2
In this case;
Initial volume, V1 = 2.0 L
Initial pressure, P1 = 101.5 kPa
Final volume, V1 = 0.25 L
We are required to determine the new pressure;
Replacing the known variables with the values;
= 812 kPa
Thus, the pressure of air inside the balloon after squeezing is 812 kPa
Answer:
Honey is an homogeneous mixture
Salsa is an heterogeneous mixture
Explanation:
Honey is a sweet uniformly colored liquid that can be of a dark variety or of clear golden color. Honey is made in nature by bees from flower nectar and is used as a food additive or sweetener
Honey is a homogeneous mixture because the concentration of the components of honey are uniformly distributed throughout the mixture. Every portion has the same concentration of components
Salsa is a sauce made by mixing chopped tomatoes, onions, chilies, lime juice and seasoning and therefore consists of both solid and liquid components mixed in varying proportion such that part will have continuous that comes in between different types of solid and no two parts have exactly the same composition
Therefore, salsa is an heterogenous liquid.
