Answer:
copper
Explanation:
The density of copper is 8.96 g/cm³ and the density of zinc is 7.13 g/cm³.
density= mass/volume
⇒mass = density×volume
For copper,
mass = 8.96 g/cm³ × 1 cm³
mass = 8.96 grams
For zinc,
mass = 7.13 g/cm³ × 1 cm³
mass = 7.13 grams
It is clear that, the mass of copper is more.
Answer : The correct option is, (e) eg = trigonal planar, mg = trigonal planar
Explanation :
Formula used :
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is,
That means,
Bond pair = 3
Lone pair = 0
The number of electron pair are 3 that means the hybridization will be and the electronic geometry of the molecule will be trigonal planar.
Hence, the electron geometry (eg) and molecular geometry (mg) of is, trigonal planar and trigonal planar respectively.
Answer:
92.9 °C
Explanation:
Step 1: Given data
- Initial volume (V₁): 450. mL
- Initial temperature (T₁): 55.0 °C
- Final volume (V₂): 502 mL
Step 2: Convert 55.0 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 55.0 + 273.15 = 328.2 K
Step 3: Calculate the final temperature of the gas
If we assume constant pressure and ideal behavior, we can calculate the final temperature of the gas using Charles' law.
T₁/V₁ = T₂/V₂
T₂ = T₁ × V₂/V₁
T₂ = 328.2 K × 502 mL/450. mL = 366 K = 92.9 °C
