Answer:
(Most accurate) pippete>graduated cylinder>beaker>balance (Least accurate)
Explanation:
- <em>Most accurate. A pipette prived the most accurate method for delivering a known volume of solution, for example, a 10mL transfer pipette has an accuracy of ±0.02mL</em>
- A graduated cylinder is specifically used to deliver a known volume, its typical accuracy is ±1%, this means that a 100ml graduated cylinder is accurate to ±1mL.
- A beaker is a multipurpose cylindrical glass mainly used to hold liquids. Even though they are graduated, these marks are an estimation, the beaker's accuracy is around 10%.
- Least accurate. A balance measures an object's mass, even though water's density is close to 1, a balance is not the ideal equipment to measure volume, its capacity usually goes between 100-200grams and can measure mass to the nearest ±0.01mg to ±1mg.

Explanation:
Answer:
Buy local and eat a more diversified diet including less meat and dairy to reduce your carbon emissions resulting from the use of fossil fuel-based fertilizers, pesticides, and gas required to produce and transport of the food you eat. Support clean energy sources.
Explanation: or
Alternatives to drivingWhen possible, walk or ride your bike in order to avoid carbon emissions completely. Carpooling and public transportation drastically reduce CO2 emissions by spreading them out over many riders.
The answer is D, reactant.
Answer:
Approximately
.
Explanation:
Balanced equation for this reaction:
.
Look up the relative atomic mass of elements in the limiting reactant,
, as well as those in the product of interest,
:
Calculate the formula mass for both the limiting reactant and the product of interest:
.
.
Calculate the quantity of the limiting reactant (
) available to this reaction:
.
Refer to the balanced equation for this reaction. The coefficients of the limiting reactant (
) and the product (
) are both
. Thus:
.
In other words, for every
of
formula units that are consumed,
of
formula units would (in theory) be produced. Thus, calculate the theoretical yield of
in this experiment:
.
Calculate the theoretical yield of this experiment in terms of the mass of
expected to be produced:
.
Given that the actual yield in this question (in terms of the mass of
) is
, calculate the percentage yield of this experiment:
.
