what is the percent of just the oreo(out of 100%) from the total mass of these 3 cookies combined
Answers
Answer:
Percent mass of oreo = 35.11%
Explanation:
Given:
Mass of oreo = 17.1
Mass of 1st cookie = 16.2
Mass of 3rd cookie = 15.4
Find:
Percent mass of oreo
Computation:
Total mass = Mass of oreo + Mass of 1st cookie + Mass of 3rd cookie
Total mass = 17.1 + 16.2 + 15.4
Total mass = 48.7
Percent mass of oreo = [Mass of oreo/Total mass]100
Percent mass of oreo = [17.1 / 48.7]100
Percent mass of oreo = 35.11%

The balanced chemical equation of decomposition of silver oxide is 2 Ag₂O -> 4 Ag + O₂.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

determine the kinetic energy of an 833.0 kg roller coaster car moving at a speed of 20.0 m/s
Answers
Answer:
166,600J
Explanation:
Kinetic energy (K.E), which is the energy due to motion of a body, can be calculated by using the formula;
K.E = 1/2 × m × v²
Where;
K.E = kinetic energy (joules)
m = mass of body (kg)
v = speed or velocity (m/s)
According to this question, the mass of the roller coaster is 833.0 kg while its velocity/speed is 20.0m/s.
K.E = 1/2 × 833 × 20²
K.E = 1/2 × 833 × 400
K.E = 1/2 × 333200
K.E = 166,600
Therefore, the kinetic energy of the roller coaster car is 166,600J.

Why can't krypton and xenon separate during the separation of gases in the air?
Answers
Answer:
The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.
Explanation:
Answer:
They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

There will be a rapid evolution of gas.
B)
The mass of the products will equal 339.
The solid magnesium metal will disappear.
D)
The balloon covering the container will expand.
E)
There will be a dramatic change in temperature,
Answers
Answer:
Answer: everything except E
Explanation: There was no dramatic change in temperature and i just took the assignment.
According to the law of conservation of matter, matter cannot be created not be destroyed. In this experiment, no matter loss will occur but there will be rapid evolution hydrogen gas and the balloon will expand.
What is conservation of matter?According to conservation of matter, matter can neither be created nor be destroyed but its state and properties can be changed. The total mass of the reactants will be equal to the total mass of the products.
Magnesium is a second group element and is a metal. Metal reacts with hydrogen halides to form metal halides and hydrogen gas as the reaction written below:
[tex]Mg +2 HCl \rightarrow MgCl_{2} +H_{2}[/tex]
The evolved hydrogen gas in this reaction tries to diffuses out the sealing and thus the balloon cover expands. And thus the solid magnesium metal disappears to form magnesium chloride.
The evolution of gases is exothermic and therefore, the temperature outside increases suddenly. There we can see bubbles of hydrogen in the reaction system.
Therefore, the changes that occur in the experiments are, rapid evolution of gases, solid metal disappears, sealing cover expands and there occur a rapid change in temperature. Thus options A,C,D,E are correct.
