Yes and no it depends on what u r useing
Answer:
get rid of waste material
Based on the information provided in this image shown above, the measurement to two (2) significant figures is equal to 3.50 mm.
<h3>What is measurement?</h3>
Measurement can be defined as an act or process through which the size, magnitude, dimensions, or distance traveled by a physical object or body is taken, especially for the purpose of an experiment.
<h3>What is a scale of measurement?</h3>
A scale of measurement can be defined as a classification which is used to illustrate the attributes of the values that are assigned to variables associated with a data set.
<h3>What is a
significant figure?</h3>
In Mathematics, a significant figure can be defined as the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.
Based on the information provided in this image shown above, the measurement of the film to two (2) significant figures is equal to 3.50 mm.

Data:
Explanation:
The rate constant as a function of the temperature can be expressed using the Arrhenius equation, as follows,
Then, find a value for the constant A, according to the data given in the exercise,
As the rate constant has units then, the reaction corresponds to one of first order. Then, the reaction corresponds to:
Which tell the amount of mass (mol) is produced by second per unity of volume.
Answer:
If the reaction goes twice fast, the reaction rate corresponds to,
The expression above can be reduced to:
Replacing k(T) in order to obtain the temperature T,
Replacing all values,
<span>The correct answer is Na+, reduction is the gaining of electrons by ions, the ease at which an ion or an atom gains electrons depends on its position in the electrochemical series. Electrochemical series arranges atoms of elements in order, based on the ease of gaining electrons. In this case, Na+ can easily gain electrons compared to the other ions given. We can also look at it based on the electromotive force of each (EMF); +0.77 Vb. -0.25 Vc. -2.71 Vd. +0.15; this evidently shows that Na+ can undergo reduction easily compared to the other ions</span>
