Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
Answer:
<h2>875 mL</h2>
Explanation:
The new volume can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>875 mL</h3>
Hope this helps you
Answer:
4.16 × 10⁻⁴ M/s
Explanation:
The rate of appearance of a product is the change in its concentration divided by the time elapsed.
The rate of disappearance of a reactant is minus the change in its concentration divided by the time elapsed.
The rate of the reaction is equal to the rates of appearance or disappearance divided by its stoichiometric coefficient.
Let's consider the following reaction.
2 S₂O₃²⁻(aq) + I₂(aq) → S₄O₆²⁻(aq) + 2 I⁻(aq)
The rate of dissapearance of thiosulfate is:
The rate of the reaction with respect to thiosulfate is:
The rate of the reaction with respect to the iodide ion is:
Answer:
A
Explanation:
Carbon Dioxide creates what is known as the greenhouse effect, which traps heat for a few weeks.
