Answer : The correct option is, (e) eg = trigonal planar, mg = trigonal planar

Explanation :

Formula used  :

\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]

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, CH_3^+

\text{Number of electron pair}=\frac{1}{2}\times [4+3-1]=3

That means,

Bond pair = 3

Lone pair = 0

The number of electron pair are 3 that means the hybridization will be sp^2 and the electronic geometry of the molecule will be trigonal planar.

Hence, the electron geometry (eg) and molecular geometry (mg) of CH_3^+  is, trigonal planar and trigonal planar respectively.

Answer:

The bee's energy output can be calculated directly, and related to its size. it only needs enough air resistance to counter its weight and enough power in its wings to sustain this resistance. it bee like that.

A compound is 44.7% P and the rest O. Determine its emperical formula.
svet-max [94.6K]

Answer:  

P₅O₁₂

<em>Explanation:  </em>

Assume that you have 100 g of the compound.  

Then you have 44.7 g P and 55.3 g O.  

1. Calculate the <em>moles</em> of each atom  

Moles of P  = 44.7 × 1/30.97 = 1.443 mol Al  

Moles of O = 55.3 × 1/16.00 = 3.456 mol O  

2. Calculate the <em>molar ratios</em>.  

P: 1.443/1.443 =   1  

O: 3.456/1.443 = 2.395

3. Multiply by a number to make the ratio close to an integer

P:  5 × 1         =  5

O: 5 × 2.395 = 11.97

3. Determine the <em>empirical formula </em>

Round off all numbers to the closest integer.  

P:   5

O: 12

The empirical formula is <em>P₅O₁₂</em>.

After decaying for 48 hours, one-sixteenth (1/16) of the original mass of a radioisotope sample remains unchanged. What is the h
Hunter-Best [27]

The half-life of this radioisotope : 12 hr

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}

t = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

t=48 hr

\tt \dfrac{Nt}{No}=\dfrac{1}{16}

The half-life :

\tt \dfrac{1}{16}=\dfrac{1}{2}^{(48/t\frac{1}{2} )}\\\\(\dfrac{1}{2})^4=(\dfrac{1}{2})^{48/t\frac{1}{2}}\\\\4=48/t\frac{1}{2}\\\\t\frac{1}{2}=12~hr
