Rasek [7]

Answer:

False.

Explanation:

The chemical hazard label with colors indicates the specific class of hazard. Hazardous Materials Identification System is defined as the numerical hazard rating then incorporate the use of labels with colors.

Blue color: This sign conveys the health hazards of the material, means that long-term exposure to the material can cause the problems, for example kidney damage, and emphysema.

Red for color: This sign conveys the flammability hazards of the material.

Yellow for color: This sign conveys the instability hazards of the material.

When 45 g of an alloy, at 25oC, are dropped into 100.0 g of water, the alloy absorbs 956 J of heat. If the final temperature of
taurus [48]

Answer:

The answer to the question is

The specific heat capacity of the alloy = 1.77 J/(g·°C)

Explanation:

To solve this, we list out the given variables thus

Mass of alloy = 45 g

Initial temperature of the alloy = 25 °C

Final temperature of the alloy = 37 °C

Heat absorbed by the alloy = 956 J

Thus we have

ΔH = m·c·(T₂ - T₁) where  ΔH = heat absorbed by the alloy = 956 J, c = specific heat capacity of the alloy and T₁ = Initial temperature of the alloy = 25 °C , T₂ = Final temperature of the alloy = 37 °C  and m = mass of the alloy = 45 g

∴ 956 J = 45 × C × (37 - 25) = 540 g·°C×c  or

c = 956 J/(540 g·°C) = 1.77 J/(g·°C)

The specific heat capacity of the alloy is 1.77 J/(g·°C)
