Answer:
the pig's average speed is 7 m/s
The average speed of a moving body is the ratio of the distance travelled to the time of travel. Here, the speed of the pig running 46 meters in 6 seconds is 7.6 m/s.
What is average speed ?The speed of an object is a physical quantity that measures the distance travelled by the object per unit time. Hence, it is the ratio of distance travelled to the time taken for the travel. The rate of speed is called velocity. Bot are having the standard unit of m/s.
Given that,
distance covered by the pig = 46 meters
time taken = 6 seconds
speed = distance/time.
Average speed of the pig = 46 meters/ 6 seconds = 7.6 m/s.
Therefore, if the small pig runs 46 meters in 6 seconds, it is having an average speed of 7.6 m/s.

What will happen if you heat aliquid to high temperatures?
Answer:
An increase in the temperature of a liquid causes an increase in the average speed of its molecules. As the temperature of a liquid increases, the molecules move faster thereby increasing the liquid's kinetic energy.
Compare and contrast the way energy can transfer from one object to another.
Answer:
Energy is transferred from the hotter object to the cooler one, and the difference in temperature between them decreases.Explanation

Consider the Fischer ester synthesis of methyl benzoate from benzoic acid and methanol in the presence of sulfuric acid as a catalyst. A reaction was performed in which 3.8 g of benzoic acid was reacted with excess methanol to make 2.0 g of methyl benzoate. Calculate the theoretical yield and percent yield for this reaction.
Answer:
48.8%
Explanation:
The reaction has a 1:1 mole ratio so;
Number of moles of benzoic acid reacted = mass/molar mass = 3.8 g/122.12 g/mol = 0.03 moles
So;
0.03 moles of methyl benzoate is formed in the reaction
Mass of methyl benzoate formed = 0.03 moles * 136.15 g/mol = 4.1 g
percent yield = actual yield/theoretical yield * 100/1
percent yield = 2.0 g/4.1 g * 100 = 48.8%

If you are given 64.0 grams of CH4, how many grams of H2O are made
Answer:
144 g of H₂O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4 = 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of H₂O = (2×1) + 16
= 2 + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 64 g of CH₄. This can be obtained as follow:
From the balanced equation above,
16 g of CH₄ reacted to produce 36 g of H₂O.
Therefore, 64 g of CH₄ will react to produce = (64 × 36)/16 = 144 g of H₂O.
Thus, 144 g of H₂O were obtained from the reaction.
Aqueous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid water H2O. Suppose 15.7 g of hydrochloric acid is mixed with 27. g of sodium hydroxide. Calculate the maximum mass of sodium chloride that could be produced by the chemical reaction.
Answer:
25.155 gram
Explanation:
HCl(aq.) + NaOH(aq.) ⇒ NaCl + H2O
According the above equation equal number of moles of reactant are producing same number of moles of products.
Now, no. mole of HCl = 15.7/(1+35.5) = 0.43 moles
no. of moles of NaOH = 27/(23+16+1) = 0.675 moles
Since the amount of sodium hydroxide exceeds the amount of hydrochloric acid, the maximum amount of each substance participating in the reaction is HClν ν 0.43 moles .Therefore, the maximum amount of NaCl that can be produced is as follow
= (23+35.5)×0.43 = 25.155 gram

Ellie started her reaction between the KMnO4 and malonic acid by first heating the two solutions in the hot water bath. She then removed the test tubes from the water bath and poured the KMnO4 into the 75-mL test tube containing the malonic acid. She mixed the solution, placed it back into the water bath, then started the timer. For the data collected at 75 oC, indicate how the process explained above impacts the reaction time.a. The time recorded in the lab notebook is the true reaction time because the reaction only starts after the timer is started b. The time recorded in the lab notebook is longer than the true reaction time because the reaction starts the moment the two solutions were mixed c. The time recorded in the lab notebook is the true reaction time because the reaction only starts after the mixture is placed back into the hot water bath d. The time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed
Answer:
The time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed
Explanation:
A chemical reaction is "a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction" (Oxford dictionary).
A chemical reaction begins immediately the reactants are mixed together in a reaction vessel because the particles of the reactants immediately begin to collide with each other. There is no lost time before reactions begins!
This implies that, the time recorded in the lab notebook is shorter than the true reaction time because the reaction starts the moment the two solutions were mixed.

Hydrazine (N2H4) and dinitrogen tetroxide (N2O4) form a self-igniting mixture that has been used as a rocket propellant. The reaction products are N2 and H2O. Part A Write a balanced chemical equation for this reaction. Express your answer as a chemical equation. nothing A chemical reaction does not occur for this question. Request Answer Part B What is being oxidized, and what is being reduced
Answer:
2N₂H₄+N₂O₄→3N₂+4H₂O; N₂H₄ gets oxidized, N₂O₄ gets reduced.
Explanation:
Part AThey tell us what substances react to form what products, so we can write an unbalanced chemical equation from those substances.
N₂H₄+N₂O₄→N₂+H₂O
To balance this equation, we need to make it so there is an even amount of each element on both sides of the reaction. We can do this by multiplying the amount of each substance by adding a coefficient in front of it.
2N₂H₄+N₂O₄→3N₂+4H₂O
Part BTo identify what is being oxidized and what is being reduced, look at the oxidation charges of each element.
N₂H₄ gets oxidized, N₂O₄ gets reduced.

The electron affinity of an element is positive if energy is absorbed during the process of accepting an electron and negative if energy is released during the process. Using the electron configuration of the atom or ion undergoing the addition of an electron, predict whether the electron affinity will be positive or negative for the following reactions, and classify them accordingly.
Atom or ion Electron configuration
Ne 1s22s22p6
Br 1s22s22p63s23p64s23d104p5
Na 1s22s22p63s1
Mg 1s22s22p63s2
Cl 1s22s22p63s23p6
Answer:
See explanation
Explanation:
Ne is a noble gas. It already has an octet of electrons hence, the electron affinity of neon is negative.
Br is a halogen, halogens need one electron to complete their octet. The electron affinity for bromine is negative.
Sodium is a metal that has only one electron in its outermost shell. The electron affinity of sodium is positive.
Magnesium is a metal having two electrons in its outermost shell. The electron affinity of magnesium is positive.
Chlorine is another halogen, energy is released when an electron is added to chlorine hence the electron affinity of chlorine is negative.

A 20.06-mL sample of hydrochloric acid solution requires 25.00 mL of 0.149 M sodium hydroxide for complete neutralization. What is the concentration of the original hydrochloric acid solution?
Answer:
The concentration of the original hydrochloric acid solution is - 0.1856 M
Explanation:
Lets calculate-:
Neutralization reaction follows dilute principle
[tex](N_1)(V_1)=(N_2)(V_2)[/tex] For titration between NaOH and HCl
[tex](M_1)(V_1)_H_C_l=(M_2)(V_2)_N_a_O_H[/tex]
Putting the given values ,
[tex]M_1\times 20.06ml=0.149M\times25.0ml[/tex]
[tex]M_1_H_C_l=\frac{0.149\times25.0}{20.06}[/tex]
= 0.1856 M
Hence , the concentration of hydrochloric acid solution is 0.1856 M.
