Answer:
0.432kg or 432g
Explanation:
Copper block is removed from 310C oven.
Mass of water = 1.10kg
Initial temperature of water (θ1) = 23.0C
Final temperature of water (θ2 ) = 33.0C
Specific heat of copper= 385
Specific heat of water = 4190
Let M (copper) be the mass of copper
The amount of heat lost will be absorbed by water
Q (net) = Q(water) + Q(copper) = 0 …………………(1)
Q = MCθ
For water,
Q(water) = M(water) * C(water) * (θ2-θ1)...........(2)
= 1.1 * 4190 * (33.0 -23.0)
= 1.1 *4190 * 10
= 46090J
For copper,
Q(copper) = M(copper) * C(copper) * (33.0 - 310)...........(3)
from equation 1,
Q(copper) = -Q(water)
M(copper) * C(copper) * (33.0 - 310) = - 46090
M(copper) * 385 * (-277) = -46090
M(copper) * 106645 = -46090
M(copper) = -46090 / -106645
M(copper) = 0.432kg
M(copper) = 432g
The mass of copper =432g
The mass of the copper block is 3.69kg.
To find the mass of the copper block, we can use the equation q1 = q2. The heat gained by the water is given by q1 = mcΔT, where m is the mass of the water, c is the specific heat of water, and ΔT is the change in temperature. The heat lost by the copper block is given by q2 = mcΔT, where m is the mass of the copper block, c is the specific heat of copper, and ΔT is the change in temperature. Since the water reaches a final temperature of 33.0°C, the change in temperature is ΔT = 33.0°C - 23.0°C = 10.0°C.
Using the equation q1 = q2, we have mcΔT = mcΔT. Rearranging the equation to solve for the mass of the copper block, we get m = (m1c1ΔT2) / (c2ΔT1), where m1 is the mass of the water, c1 is the specific heat of water, ΔT2 is the change in temperature of the copper block, c2 is the specific heat of copper, and ΔT1 is the change in temperature of the water. Substituting the given values, we have m = (1.10kg * 4190 J/(kg?K) * 10.0°C) / (385 J/(kg?K) * 10.0°C), which simplifies to m = 3.69kg.

Let's rank the atoms A (Gold), B (Copper), C (Carbon), and D (Silver) based on:
a. Mass (atomic mass or atomic weight)
b. Number of electrons
c. Number of protons
a. Mass (Atomic Mass or Atomic Weight):
1. Gold (A) has an atomic mass of approximately 196.97 atomic mass units (u).
2. Silver (D) has an atomic mass of approximately 107.87 u.
3. Copper (B) has an atomic mass of approximately 63.55 u.
4. Carbon (C) has an atomic mass of approximately 12.01 u.
Ranking by mass from most to least:
1. Gold (A) - 196.97 u
2. Silver (D) - 107.87 u
3. Copper (B) - 63.55 u
4. Carbon (C) - 12.01 u
b. Number of Electrons:
The number of electrons in an atom is equal to the number of protons, which is also the atomic number.
1. Gold (A) has an atomic number of 79, so it has 79 electrons.
2. Silver (D) has an atomic number of 47, so it has 47 electrons.
3. Copper (B) has an atomic number of 29, so it has 29 electrons.
4. Carbon (C) has an atomic number of 6, so it has 6 electrons.
Ranking by the number of electrons from most to least:
1. Gold (A) - 79 electrons
2. Silver (D) - 47 electrons
3. Copper (B) - 29 electrons
4. Carbon (C) - 6 electrons
c. Number of Protons:
The number of protons in an atom is equal to the atomic number.
1. Gold (A) has an atomic number of 79, so it has 79 protons.
2. Silver (D) has an atomic number of 47, so it has 47 protons.
3. Copper (B) has an atomic number of 29, so it has 29 protons.
4. Carbon (C) has an atomic number of 6, so it has 6 protons.
Ranking by the number of protons (which is the same as the ranking by the number of electrons):
1. Gold (A) - 79 protons
2. Silver (D) - 47 protons
3. Copper (B) - 29 protons
4. Carbon (C) - 6 protons
To rank the given atoms by mass, D. Silver has the most mass, followed by A. Gold, B. Copper, and C. Carbon. For number of electrons, B. Copper has the most, followed by A. Gold, C. Carbon, and D. Silver. For number of protons, B. Copper has the most, followed by A. Gold, D. Silver, and C. Carbon.
To rank the given atoms based on their mass, we can refer to the atomic mass or atomic weight of each element. The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. The element with the highest atomic mass will have the most mass. In this case, the ordering would be D. Silver, A. Gold, B. Copper, and C. Carbon.
To rank the atoms based on the number of electrons, we can refer to the atomic number of each element. The atomic number represents the number of protons, which is equal to the number of electrons in a neutral atom. The element with the highest atomic number will have the most electrons. In this case, the ordering would be B. Copper, A. Gold, C. Carbon, and D. Silver.
To rank the atoms based on the number of protons, we can again refer to the atomic number of each element. The atomic number represents the number of protons in the nucleus. The element with the highest atomic number will have the most protons. In this case, the ordering would be B. Copper, A. Gold, D. Silver, and C. Carbon.

b. If you have an accompanying licensed driver
c. If you drive on less traveled roads
d. If you get permission from the local police
When a driver's license is suspended, typically, one cannot drive. However, one might be able to drive under certain conditions, like obtaining an essential need driver license or a hardship license. Laws vary by location, hence local transportation operating rules must be consulted.
When your driver's license is suspended, under most jurisdictions you are generally not allowed to drive. However, there can be certain exceptions to this rule. The correct answer among the provided options would be (a) If you obtain an essential need driver license. This type of license, also referred to as a hardship or restricted license, may allow you to drive under certain conditions, for instance, for work or medical appointments. It's important to note that laws may vary by location, so it is always important to consult with local legal sources or transportation departments to understand specific regulations and processes related to obtaining conditional driving permissions when your license is suspended.
