11) Which statement about covalent bonds is true? A) Covalent bonds are generally weaker than ionic bonds because they form full
Cerrena [4.2K]
<h3><u>Answer;</u></h3>

C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.

<h3><u>Explanation;</u></h3>
  • <em><u>Covalent bond is a type of bond that results from the sharing of electrons between two non-metal atoms. </u></em>
  • <em><u>Ionic bond on the other is a type of bond that results from the transfer of electrons between metal atoms and non metal atoms, where a metal atom looses electrons and a non-metal atom gains electrons.</u></em>
  • <em><u>The amount of energy required to break an given bond determines how strong a particular bond is.</u></em> Ionic bonds require more energy to break as compared to covalent bond and therefore they are stronger than the covalent bonds.

olchik [2.2K]

Answer:

a) 665 kg.m/s

b) 2.97 kN

Explanation:

The impulse is given by:

J=\Delta p\\J=m(v_a-v_b)

where

va=velocity after

vb=velocity before

The velocity just before is given by:

v_b=\sqrt{2*9.81m/s^2*9m}=13.3m/s(-\hat{j})

The velocity just after is zero because there wasn't a rebound.

So the impulse is:

J=50kg*(0-13.3m/s(-\hat{j}))\\J=50kg*(0+13.3m/s(\hat{j}))=665kg.m/s

The impulse is also given by:

J=\Delta p=F* \Delta t\\so:\\F=\frac{J}{\Delta t}\\\\F=\frac{665kg.m/s}{0.224s}=2.97kN

After a nucleus with 85 protons undergoes alpha decay, it has<br><br> ? protons.
Valentin [98]

Answer:

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.

Explanation:

In an alpha particle there are two protons

In the given substance's nucleus, there are total of 85 protons

After the decay, the proton number reduce

The current proton number after decay is

85 -2 = 83

After a nucleus with 85 protons undergoes alpha decay, it has  83 protons.
