Explanation:
You are given a piece of paper and a match. The paper has a mass of 2.5 g. You then light the match and light the piece of paper on fire. After it burns, the remaining bits of paper weigh 0.5 g. Does this demonstration violate the conservation of mass? Explain why or why not?
Answer:
No
Explanation:
No. The demonstration does not violate the conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed in a reaction. However, mass can be converted from one form to another during the reaction.
In this case, even though the remaining bits of paper weigh 0.5 g while the original paper weighed 2.5 g, the ashes and smoke/gas from the burning will all add up to the lost weight of the paper.
The burned part has been converted into other forms. If the smoke/gas and the ashes are properly captured, they will mark up with the weight of the remaining paper to give the weight of the original paper.
The answer to the question on whether the burning violates the law of conservation of mass, we say that;
No, the demonstration does not violate the conservation of mass because the mass formed still adds up to the original mass.
The law of conservation of mass states that mass in an isolated system, matter can neither be created nor destroyed by chemical reactions or physical transformations. However, it could involve change in mass from one form to another.
Now, we are told that the remaining bits of paper has a mass of 0.5 g while the original paper has a mass 2.5 g. The reason why the mass left is 0.5 kg is because the ashes and smoke from the burning will add up to give the original weight of the paper.
Thus, since when the ashes, and smoke add up to still give the original mass of 3.5 g, it means that the mass is neither created nor destroyed

5. 54 J of heat is required to raise the temperature of a 2.47g unknown substance from 17.10C to 46.70C. a) Calculate the specific heat of the substance b) What is the substance
Answer:
C = 0.7385J/g°C
Explanation:
Heat energy (Q) = 54J
Mass (m) = 2.47g
Initial temperature (T1) = 17.10°C
Final temperature (T2) = 46.70°C
Specific heat capacity of substance (c) = ?
Heat energy of a substance (Q) = Mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature of substance = T2 - T1
Q = mc∇T
Q = mc (T2 - T1)
54 = 2.47 * c * (46.70 - 17.10)
54 = 2.47 * 29.6 * c
54 = 73.112c
C = 54 / 73.112
C = 0.7385
Specific heat capacity of the substance is 0.7385J/g°C
B.
The specific heat capacity of the above substance does not match any metal in the periodic table, however the closest to it was potassium with a value of 0.7536J/g°C and silicone with value of 0.711756J/g°C
Answer:
The specific heat of the substance is 0.739 J/g°C
The substance can be glass or SiO2
Explanation:
Step 1: Data given
Heat required = 54 J
Mass of the substance = 2.47 grams
Initial temperature = 17.10 °C
Final temperature = 46.70 °C
Step 2: Calculate the specific heat of the substance
Q = m*c¨*ΔT
⇒with Q = the heat required =54 J
⇒with m = the mass of the substance = 2.47 grams
⇒with c = the specific heat of the substance = TO BE DETERMINED
⇒with ΔT = the change of temperature = T2 - T1 = 46.70 - 17.10 = 29.60 °C
c = Q / (m*ΔT)
c = 54 / (2.47 * 29.60)
c = 0.739 J/g°C
The specific heat of the substance is 0.739 J/g°C
The substance can be glass or SiO2

1What is one major difference between fossil fuels and biofuels?
ABurning fossil fuels releases greenhouse gases; burning biofuels releases no greenhouse gases incorrect answer
B Fossil fuels exist in unlimited supply; our supply of biofuels may run out someday incorrect answer
C Fossil fuels are very expensive to manufacture; biofuels are very inexpensive to manufacture incorrect answer
D You can drive farther on a single tank of fossil fuel than you can on a single tank of biofuel
The major difference between fossil fuels and biofuels is you can drive farther on a single tank of fossil fuel than you can on a single tank of biofuel. The correct option is D.
What are fossil fuels?A fossil is a naturally extracted fuel, for example, the anaerobic decompression of buried dead animals, while biofuel is any biomass fuel, plant or algae, or animal waste. Since these materials can quickly be replenished, biofuels are considered renewable energy sources.
Biofuels are created from renewable feedstocks, unlike fossil fuels, which are finite resources. As a result, their manufacturing and use might theoretically continue forever.
Therefore, the correct option is D. You can drive farther on a single tank of fossil fuel than you can on a single tank of biofuel.

can you answer this?
Mass: 108g
volume:12cm to the third power (3)
Answer:
The density is 0.0625 g/cm³
Explanation:
In order to find the density, you have to use its formula, ρ = mass/volume. Then substitute the following values into the formula :
[tex]ρ = \frac{mass}{volume} [/tex]
Let mass = 108g,
Let volume = (12³)cm³ = 1728cm³,
[tex]ρ = \frac{108}{1728} [/tex]
[tex]ρ = \frac{1}{16} [/tex]
[tex]ρ = 0.0625g / {cm}^{3} [/tex]

Identify how many Sulfur atoms are in the product of this chemical
equation *
BaSO4 + H2SO4
Ba(HSO4)2
O A. 2
O B.4
O C. 8
O D. Unknown
Answer:
2
Explanation:
Equation of reaction
BaSO₄ + H₂SO₄ → Ba(HSO₄)₂
From the above equation of reaction, it is evident that there are 2 atoms in the product side of the reaction which is only logical because every chemical reaction obey the law of conservation of mass which states that matter can neither be created nor destroyed but can changed from one form to another.
In the reactant side, we have 2 atoms of S from the two reactants coming together.
One sulfur atom from BaSO₄ and the other from H₂SO₄. So therefore, only 2 sulfur can be produced since the reaction has to observe law of conservation of matter
