Answer:
is the limiting reagent
Explanation:
To calculate the moles :


The balanced chemical reaction is :
According to stoichiometry :
1 moles of
require = 2 moles of 
Thus 0.625 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent as it is present more than the required amount.
Answer:
108 kPa
Step-by-step explanation:
To solve this problem, we can use the <em>Combined Gas Laws</em>:
p₁V₁/T₁ = p₂V₂/T₂ Multiply each side by T₁
p₁V₁ = p₂V₂ × T₁/T₂ Divide each side by V₁
p₁ = p₂ × V₂/V₁ × T₁/T₂
Data:
p₁ = ?; V₁ = 34.3 L; T₁ = 31.5 °C
p₂ = 122.2 kPa; V₂ = 29.2 L; T₂ = 21.0 °C
Calculations:
(a) Convert temperatures to <em>kelvins
</em>
T₁ = (31.5 + 273.15) K = 304.65 K
T₂ = (21.0 + 273.15) K = 294.15 K
(b) Calculate the <em>pressure
</em>
p₁ = 122.2 kPa × (29.2/34.3) × (304.65/294.15)
= 122.2 kPa × 0.8542 × 1.0357
= 108 kPa
Answer: The number of protons
Explanation:
Answer:
A) Test(independent) variable is bat wings.
B) Result (dependent) Variable is the Polyjuice Potion.
C) Cauldrons and fire
Explanation:
A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.
Now, in this experiment, what is being tested is are the bat wings.. Thus;
Test(independent) variable is bat wings.
B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.
Thus, Result (dependent) Variable is the Polyjuice Potion.
C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire
The primary components of rocks are minerals.
