Find the mass of copper that was

Chemistry
1 answer:
galina1969 [7]3 years ago
5 0

Answer:

143.12 g

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T₁) = 32 °C

Final temperature (T₂) = 130 °C

Heat (Q) = 5400 J

Specific heat capacity (C) = 0.385 J/gºC

Mass (M) =?

Next, we shall determine the change in temperature of copper. This can be obtained as follow:

Initial temperature (T₁) = 32 °C

Final temperature (T₂) = 130 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 130 – 32

ΔT = 98 °C

Finally, we shall determine the mass of copper. This can be obtained as follow:

Change in temperature (ΔT) = 98 °C

Heat (Q) = 5400 J

Specific heat capacity (C) = 0.385 J/gºC

Mass (M) =?

Q = MCΔT

5400 = M × 0.385 × 98

5400 = M × 37.73

Divide both side by 37.73

M = 5400 / 37.73

M = 143.12 g

Therefore, the mass of copper is 143.12 g

Calculate the mass of butane needed to produce 61.9 g of carbon dioxide
ELEN [110]

Answer:

20.4g

Explanation:

First, we need to write a balanced equation for the reaction of butane to produce carbon dioxide.

When butane undergo Combustion, it will produce carbon dioxide and water as shown below:

2C4H10 + 13O2 —> 8CO2 + 10H2O

Molar Mass of C4H10 = (12x4) + (10x1) = 48 + 10 = 58g/mol

Mass of C4H10 from the balanced equation = 2 x 58 = 116g

Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

Mass of CO2 from the balanced equation = 8 x 44 = 352g

From the equation,

116g of C4H10 produced 352g of CO2.

Therefore, Xg of C4H10 will produce 61.9g of CO2 i.e

Xg of C4H10 = (61.9 x 116)/352 = 20.4g

Therefore, 20.4g of butane(C4H10) is needed to produce 61.9g of CO2

Why can’t liquids change volume but gases can
natta225 [31]

Explanation:

Liquids cannot change volume but gases can because they have a fixed shape like solids.

Liquids have strong intermolecular forces binding their molecules together resulting is fixed ordering.

  • Gases are randomized with their molecules haphazardly arranged.
  • This allows them to expand spontaneously on their own.
  • Molecules of liquids are more tightly packed compared to gases.
  • In a liquid, the molecules have a less random pattern of motion and can only slide past one another.
  • In a gas, the molecules are in continuous random, straight line motion.

When you count up the electrons in a Lewis Structure, do double and triple bonds count as 4 or 6 electrons?
natima [27]

Answer:

Double=4 and triple=6

Explanation:

This is because double bonds are two pairs of electrons are shared between atoms and triple bonds are three pairs, and one pair of electrons is 2, so 2 x 2=4 and 2 x 3=6.
