Answer: we can make our own water and not take any water from animal.
Explanation:
Sodium oxide reacts with water to make sodium hydroxide.
1. Write and balance the equation.
2. List all the mole ratios.
3. How many moles of water are needed to react with 18.4 moles of sodium oxide?
4. How many grams of sodium hydroxide are formed when 4.5 moles of sodium oxide react with excess water?
5. How many grams of water are needed to make 5.65 moles of sodium hydroxide?
6. How many grams of sodium hydroxide are formed when 23.7 g of sodium oxide react with excess water?
7. How many liters of water are required to form 93.4 g of sodium hydroxide?
Answer:
So the total mass is 50 plus 150 grams the heat capacity 4.18 joules per gram per degree C. And the temperature change is 36 minus 25 and so we can calculate Delta H for the reaction that takes place.

Explanation:
kaillie was talking and was distracted as she stirred sugar into her tea. when she finally noticed, there was a few crystals of sugar in the bottom of her cup that would not dissolve. what type of tea solution did kaillie?
a. unsaturated
b. saturated
c. supersaturated
d. cannot be determined
Answer:
Supersaturated
Explanation:
The tea has absorbed and dissolved as much sugar as it could. If there is sugar left at the bottom, it means the solution is supersaturated because it can't absorb any more.
The Volume of a gas is measured to be 675.6 mL at 61.8 C. If the volume of the gas were changed to 410.9 mL, what would the final temperature be?
Answer:
203.63 K
Explanation:
Using Charles law equation,
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information in this question,
V1 = 675.6 mL
V2 = 410.9 mL
T1 = 61.8°C = 61.8 + 273 = 334.8K
T2 = ?
Using V1/T1 = V2/T2
675.6/334.8 = 410.9/T2
Cross multiply
675.6 × T2 = 334.8 × 410.9
675.6T2 = 137569.32
T2 = 137569.32 ÷ 675.6
T2 = 203.63 K

A gas occupies 450. mL 3 atm. If its volume decreases to 0.200 L then what will its new pressure be?
Assume constant temperature and mass.
Show your work.
Answer:
6.75 sym.
Explanation:
Boyle's Law: The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.
Empirically => P ∝ 1/V => P = k(1/V) => k = P·V
For any conditions of Pressure & Volume, Pressure x Volume is a constant.
Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ = P₁V₁ / V₂
=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.

Diamond has a hardness of 10 and chalk a harness of 1. Explain what this means.
Answer:
they have different forces holding the atoms together
Explanation:
diamond has a strong convalent bond holding the particles together while chalk has weak van der waals forces holding the particles together hence the diffrence in hardness
What is the molarity of a solution with 2 moles of HCl in 2000 mL?
Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
Now,
The molarity of the solution will be:
= [tex]\frac{Moles}{Liters}[/tex]
On substituting the values, we get
= [tex]\frac{2}{2}[/tex]
= [tex]1 \ M[/tex]

Calculate the percent ionization of a 0.381 M solution of hydrocyanic acid.
Answer:
.00402 %
Explanation:
hydrocyanic acid (HCN) is a weak acid with a Ka of 6.17*10^-10 so you need to do a RICE table
initial concentration of HCN is .381 and initial H+ and CN- concentration is 0.
that means the equillibrium concentration of HCN will be (.381-x) and H+ and CN- will be x
put that into the formula for Ka, so it'll be Ka = x^2/(.381-x) and then use quadratic equation to solve. You'll end up getting x = 1.5 * 10^-5.
Then to find percent ionization you solve (concentration of formed ions / initial HCN)
Which will be (1.5 * 10^-5 / .381) * 100 = .00402 % making it a very weak acid <3
Identify the gas law that applies to the following scenario: A 36.5 liter balloon holding 2.9 moles of carbon dioxide leaks. If we are able to determine that 1.2

O Boyle's Law
O Charles' Law
O Gay-Lussac's Law
Avogadro's Law
Answer:
Avogadro's Law; 15.1L
Explanation:
Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.
Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula [tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex].
Guy-Lussac's Law- As temperature increases, pressure increases, so they are proportional. We see this in the formula [tex]\frac{P1}{T1} = \frac{P2}{T2}[/tex].
Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula [tex]\frac{V1}{n1} = \frac{V2}{n2}[/tex].
Plugging in the values based on Avogadro's Law, we'll have:
[tex]\frac{36.5}{2.9} = \frac{V2}{1.2}[/tex]
12.6 = [tex]\frac{V2}{1.2}[/tex]
12.6 x 1.2 = V2
15.1L =V2

If you have 0.50 L of 0.45 M sodium bromide. How many grams of sodium bromide are present?
Answer:
23.175g
Explanation:
0.45 mole of NaBr is in 1 liter
? moles of NaBr is in 0.50 liter
0.50 × 0.45 = 0.225 of NaBr
1 mole of NaBr = 23 + 80 = 103g
0.225 moles of NaBr = ?
0.225 × 103 = 23.175g
