Answer: B. a molecule

Explanation: Covalent bond is formed by the sharing of electrons between atoms.

H_2 is a molecule formed by the sharing of electrons between two hydrogen atoms.

An ion is formed by losing or gaining electrons.

Na^+:10:[Ne]

A neutral atom is one which contains equal number of protons and neutrons.

Na:11:[Ne]3s^1

A noble gas is one which contains completely filled orbitals.

At 150°C the decomposition of acetaldehyde CH3CHO to methane is a first order reaction. If the
Crank

The decomposition time : 7.69 min ≈ 7.7 min

<h3>Further explanation</h3>

Given

rate constant : 0.029/min

a concentration of  0.050 mol L  to a concentration of 0.040 mol L

Required

the decomposition time

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time

For first-order reaction :

[A]=[Ao]e^(-kt)

or

ln[A]=-kt+ln(A0)

Input the value :

ln(0.040)=-(0.029)t+ln(0.050)

-3.219 = -0.029t -2.996

-0.223 =-0.029t

t=7.69 minutes

as any personal information of clients, customers, employees, guests, or anyone else exposed in the incident?
Elena L [17]

Answer:

"Protecting the privacy of your employees is critical to the long term success of your business. Senior leadership, high-profile executives and their families, as well as other customer-facing employees are particularly vulnerable to targeting to bad actors when their personal information is exposed. Other potential sources of danger include disgruntled employees, ex-employees and even customers."

Hope this helps :)

No pressure but anyone who can answer these is a genius. (Please fill in the question mark)
disa [49]

use variable

1K₂MnF₆ + aSbF₅⇒ bKSbF₆ + cMnF₃ + dF₂

K, left=2,right=b⇒b=2

Mn, left=1, right=c⇒c=1

Sb, left=a, right=b⇒a=b=2

F, left=6.1+5a, right=6b+3c+2d

equation:

6+5(2) = 6(2)+3(1)+2d

16=15+2d

1=2d

d=0.5

So the reaction equation becomes:

1K₂MnF₆ + 2SbF₅⇒ 2KSbF₆ + 1MnF₃ + 0.5F₂ x2

2K₂MnF₆ + 4SbF₅⇒ 4KSbF₆ + 2MnF₃ + F₂
