Answer:

No

Explanation

I say no because that could possibly put many species of animals i danger of nuclear reaction. Not only would it put many animals in danger it would put humans plant and most likely make that area a toxic waste for years

Answer:

No

Explanation:

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

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.

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.

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]

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

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
