(b) 3, 3, +2

Explanation:

Of all the given options, B is wrong. A set of quantum numbers cannot be given as 3, 3, +2. The given numbers are for:

Prinicipal quantum number(n)
Azimuthal quantum number(l) which is l = n-1
Magnetic quantum number

According to Pauli's exclusion principle "no two electrons in an atom can have the same set of the four quantum numbers". This principle indicates that no two electrons in the same orbital can spin in the same direction.
The value 3, 3, +2 is a violation of this rule. Here the principal quantum number and the azimuthal quantum numbers are the same.

determine the final temperature of a gold nugget parentheses Mass equals 376 G parentheses that starts at 398k and loses 4.85 KJ

maw [93]

Answer:

297.23 K

Explanation:

Given that:

the mass of the gold nugget (m) = 376 g

the initial temperature $T_1$ = 398 K

amount of heat lost Q = -4.85 kJ = -4.85 × 10³

specific heat capacity (c) = 0.128 J/g° C

Using the formula for calculating the Heat energy

$Q = mc\Delta T \\ \\ Q = m\times c\times (T_2-T_1)$

$-4.85 \times 10^3 = 376 \times 0.128 \times (T_2 - 398) \\ \\ -4.85\times 10^3 = 48.128(T_2 - 398) \\ \\ \dfrac{-4.85\times 10^3}{48.128}= (T_2 - 398) \\ \\-100.77 = T_2 -398\\\\T_2 = -398 +100.77\\ \\ \mathbf{ T_2 = 297.23K}$

A student calculates the volume of a graduated cylinder to be 43.26 ml. The actual volume is 42.32 ml. What is the percent error

Tpy6a [65]

Answer:

2.2%

Explanation:

Percentage error,

You apply the formula,

[(Estimated value - Actual value)/Actual value] × 100%

; [(43.26 - 42.32)/42.32] × 100

; (0.94/42.32) × 100

; 0.022 × 100

Percent error = 2.2%
