Answer:
hello ! i just did this project and received a 100,, so here you are ::
1. I hypothesize that if you continue to add more drops, then the time it takes will continue to increase.
2. A; 9.70 secs, B; 14.63 secs, C; 18.78 secs, D; 28.70 secs, E; 31.45 secs.
3. The formation continued to increased. As more was added, the time it took to reach the full reaction was increased.
4. Yes.
5. When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
6. 6mL.
Step-by-step explanation:
for this one it was simple, they are only asking you what you think will happen to the time if they increase the number of drops. remember to use the "if....then..." format.i recorded the container labeled and the time it took for the solution to turn black. they are asking the same thing that they are for the hypothesis but this time after watching the video you know what actually happens. in this case, the more drops you put in the longer it takes for it to react. write this one down without the if then format.for mine, i got it correct but you can put yours wrong on purpose if youd like.i looked this one up, but it makes sense. this is correct, so dont worry.like i said,, i go this correct so dw ! <3
The rate of reaction depends on the slow step of a reaction.
A hypothesis is a tentative explanation of an observation. This question refers to an experiment so I will try to explain as much as possible. We can see that the rate of reaction is determined by the concentration of the ascorbic acid.
Hence, we can assert that, the more the concentration of the ascorbic acid, the lower the rate of reaction. The rate of reaction depends on the slow step of a reaction.
We know that the molar mass of ascorbic acid is 176 g/mol. The mass of ascorbic acid is 6 g. Hence;
Number of moles of ascorbic acid = 6 g/176 g/mol = 0.034 moles
concentration of ascorbic acid = 0.034 moles/20 × 1 × 10-3 = 1.7 M

10.ABCD is a rhombus such that measure of angle ACB is 40º find the measure of angle ADC.
Answer:
ADC = 100 degrees
Step-by-step explanation:
Please check attachment for diagrammatic representation of the Rhombus
From what we can see in the diagram;
angle CBD and CDB are equal
The reason for this is that we have an isosceles in triangle CBD
CBD = 90- ACB
CBD = 90-40 = 50
We need ADB to completely calculate ADC
CAB is also 40 from the isosceles ABC
That means DBA = 90 - CAB = 90-40 = 50
So from isosceles ABD, we have that ADB is also 50
Mathematically;
ADC = ADB + DBA
ADC = 50 + 50
ADC = 100

isosceles and equilateral triangles (please help me as fast as you can thank you)
Answer:
x = 71°
x = 19°
x = 34°
Step-by-step explanation:
In rectangle ABCD. By exterior angle theorem:
x + 65° = 46° + 90°
x + 65° = 136°
x = 136° - 65°
x = 71°
Since, XYZ is an equilateral triangle,
Therefore, m(angle XZY) = 60°, So, by exterior angle theorem:
m angle XZY = x + 41°
60° = x + 41°
60° - 41° = x
19° = x
x = 19°
PQR is an isosceles triangle. In which PQ = PR.
Therefore,
m(angle PRQ) = m(angle PQR) = 69°
By exterior angle theorem:
x + 35° = 69°
x = 69° - 35°
x = 34°
40 + 3 = 15

use distributive property to write an expression 0.4(-5-7y-13.8)
Answer: -2.8y - 7.52
The simplified form of the expression is -2.28y - 7.52.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is a number used before a phrase.
Given:
An expression,
0.4(-5-7y-13.8).
Solving the expression with the help of distributive property,
0.4 x -5 - 0.4 x 7y - (0.4 x 13.8).
= -2 -2.8y - 5.52
= -2.28y - 7.52
Therefore, -2.28y - 7.52 is the solution.

What is (3x+12)-(6x+5)
Answer: -3x + 7
Step-by-step explanation: All you have to do is combine like terms
First, you combine 3x - 6x which, will give you -3x
Second, you combine 12 - 5 which will give you 7
3x - 6x = -3x
12 - 5 = 7
So, combine the answers and you will get -3x + 7

Answer:

Step-by-step explanation:
the range is all the possible numbers on the Y axis. We can see that the graphs peaks at 3 and then goes down both ways. This means that eventually the y axis will be equal to all real numbers less than 3
The range of the function looks to be all real numbers less than or equal to -1, according to the provided graph. The best choice is B.
What is a range of a function?This is due to the fact that the graph's horizontal line at y=-1, which shows that the function accepts all values less than or equal to -1, stretches eternally in both directions.
The collection of all potential output values that a function can take on is generally referred to as the function's range. You can look at the vertical spread of the graph to see what values the function can take on in order to determine the range of a function from its graph.
Observe that the accompanying graph features a horizontal line at y=-1 that spreads out infinity in both directions. This indicates that for all values of x, the function takes on the value of -1.
The graph also features a vertical line at x=2 that goes on forever in both directions, as can be seen. This shows that the function can accept any value of y for x=2.
Combining these findings, we can determine that the function has a range of all real numbers less than or equal to -1 since it takes on the value of -1 for all x and the range of potential values of y is unrestricted.
