Answer:
False
Explanation:
The slope of a velocity-time graph gives acceleration. Acceleration can be defined as the change in velocity with time.
A slope denotes the gradient of line. It takes into consideration the changes on both y and x axis. The ratio of the changes gives the slope.
On a velocity-time graph, the y-axis is the velocity and the x-axis is time. The change in velocity with time gives acceleration.
The slope of an acceleration
-time graph is not velocity.
Answer:
positive: proton
negative: electrons
no charge/nuetral: nuetron
Explanation:
no charge could be also described as nuetral.
<u>Answer:</u> The correct answer is geographical map.
<u>Explanation:</u>
Model is defined as the three dimensional representation of a proposed structure in a smaller scale.
For the given options:
<u>Option 1:</u> PV = nRT
This is a proposed law. This law is known as ideal gas law. A law is defined as the rule which defined a correct procedure. For any gas behaving ideally, this law is used.
<u>Option 2:</u> Geographical map
Map is defined as the diagrammatic representation of an area of land or sea which also shows physical features, roads, cities etc..
A 3-D model can be prepared for geographical map.
<u>Option 3:</u> I believe that aliens exist
This is a hypothetical statement. It is a smart guess by the means of set of assumptions and observations. For its validation, we need to conduct some experiments.
Hence, the correct answer is geographical map.

<h3>To find the empirical formula you need the relative atomic mass of each element!</h3>
N = 14
H = 1
S = 32.1
<h3>You can simply change the percentages into full grams</h3>
N = 12.20
H = 6.06
S = 48.45
<h3>Then you use this to find the Number of moles = amount in grams / atomic mass</h3>
N = 12.20 ÷ 14 = 0.8714
H = 6.06 ÷ 1 = 6.06
S = 48.45 ÷ 32.1 = 1.541
<h3>Then divide each number of moles by the smallest value:</h3>
N = 0.8714 ÷ 0.8714 = 1
H = 6.06 ÷ 0.8714 = 6.9 ≈ 7
S = 1.541 ÷ 0.8714 = 1.76 ≈ 2
So that means that there are 1 Nitrogen, 7 hydrogen, and 2 sulfur. This means the empirical formula would be:
NH₇S₂
Hope this helps!
Answer:
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
