The acceleration of the turtle, given the data from the question is 0.4 m/s²
What is acceleration?This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
a is the acceleration v is the final velocity u is the initial velocity t is the time How to determine the accelerationThe acceleration of the turtle can be obtained as follow:
Time (t) = 10 sInitial velocity (u) = 1 m/sFinal velocity (v) = 5 m/sAcceleration (a) =?a = (v – u) / t
a = (5 – 1) / 10
a = 4 / 10
a = 0.4 m/s²
Thus, acceleration of the turtle is 0.4 m/s²

Estimate 16.540 +9.32 by first rounding each number to the nearest tenth.plis i need it
Answers
Answer:
Explanation:
16.540 + 9.32 by rounding each number to the nearest tenth
so 16.540 the number in the tenth place is 5, if its 5 then you have to round up because 1-4 you need to round down, and 5-9 you would have to round up. if you round 16.540 to the nearest tenth would be 17.
Next, if 9.32 the number in the tenth place is 3, since is 5 below you would have to round down which rounds down to 9
So its 17+9 which your answer would be 26.
A mass of 1.71 g pure barium hydroxide is transferred quantitatively to a 250 cm3
volumetric flask and made up to the mark with distilled water. Using a pipette, 25.0 cm3
of the barium hydroxide solution are placed in a conical flask and a few drops of methyl
orange indicator are added. Hydrochloric acid is added slowly from a burette until the
endpoint is reached. The titre value is 12.6 cm3
What will the colour change of the indicator at the endpoint be?
Answers
The methyl orange indicator will change from red to yellow at the titration's endpoint.
How can the color of the indicator's change at the terminus be determined?An acid-base indicator called methyl orange changes color between the pH ranges of 3.1 and 4.4. In acidic and basic solutions it is red and yellow, respectively
In this instance, an acid, hydrochloric acid, is being used to titrate the barium hydroxide solution. The pH of the solution will fall as we add the acid since it will neutralize the base. The hue of the methyl orange indicator will vary when the pH ranges from 3.1 to 4.4
All of the barium hydroxide will have interacted with the hydrochloric acid by the time the titration is complete leaving a neutral solution. When the methyl orange indicator becomes yellow the solution's pH is in the basic range.
Therefore, the methyl orange indicator will change from red to yellow at the titration's endpoint.

Calculate the number of moles of phosphoric acid (H3PO4) formed by the reaction of 10 moles of sulfuric acid (H2SO4).
Answers
Answer:
The balanced chemical equation for the reaction of sulfuric acid (H2SO4) with calcium phosphate (Ca3(PO4)2) to produce phosphoric acid (H3PO4) and calcium sulfate (CaSO4) is:
3H2SO4 + Ca3(PO4)2 → 2H3PO4 + 3CaSO4
From the balanced equation, we can see that for every 3 moles of sulfuric acid that react, 2 moles of phosphoric acid are produced.
So, if 10 moles of sulfuric acid react, we can calculate the amount of phosphoric acid produced as follows:
10 moles H2SO4 × (2 moles H3PO4/3 moles H2SO4) = 6.67 moles H3PO4
Therefore, 10 moles of sulfuric acid reacting would produce 6.67 moles of phosphoric acid.

Molarity (M) is the amount of a substance in a sure quantity of solution. Molarity is described because the moles of a solute according to liters of an answer. Molarity is also called the molar attention of an answer.
Calculation:-
mass = 0.600 g
the molar mass of NaNO₃ = 85 g
moles = 0.600/85
= 0.007 moles
volume = 2 L
molarity = moles/volume
= 0.007 /2
= 0.035 M
Molar concentration is a measure of the attention of a chemical species, specifically of a solute in an answer, in terms of the amount of substance in step with the unit extent of the answer.

The objective of this question is to draw the major organic product and select the correct IUPAC name for the organic reactant. If there is more than one major product, both may be drawn.
From the image attached below; we would see the reaction that occurs between the alkene and the HBr (hydrobromic acid). What really occur in the reaction is that; in the presence of HBr with an alkene compound a secondary 2° carbocation is usually formed. This secondary 2° carbocation formed is usually unstable, so what we called an hydride shift occurs (Markovnikov's product) here to form a stable tertiary 3° carbocation.
The correct IUPAC name for the organic reactant is : 3-methylbutene

Describe the three main types of plate boundary interactions:
Divergent boundaries:
Convergent boundaries:
Transform boundaries:
Answers
Answer:
In the explanation
Explanation:
Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.
Convergent: When two plates are moving towards each other.
If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.
If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.
Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

The two main postulates that was given by Antoine Lavoisier are, oxygen play an important role in combustion and the other is mass of the reactant and product is conserved. Therefore the mass of HF is 28grams.
What is law of conservation of mass?According to Law of conservation of mass, mass can neither be created nor be destroyed. Mass can only be transformed from one form to another. The law of conservation of mass was given by Antoine Lavoisier. Every reaction in nature follow the law given by Antoine Lavoisier that is mass is always conserved.
H\(_2\) + F\(_2\) → 2HF
Mass of H\(_2\)=8Grams
mass of F\(_2\)= 20grams
According to law of conservation f mass
mass of H\(_2\) + mass of F\(_2\) = mass of HF
Substituting all the given values, we get
