How many positively charged nucleons are in an atom of ^50 24Cr?

Chemistry
1 answer:
lorasvet [3.4K]3 years ago
5 0

Answer:

positively charged nucleons are 24

Explanation:

Given element:

           ₂₄⁵⁰ Cr

The superscript before the symbol of the atoms is mass number

The subscript before the symbol is the atomic number

  Cr is the symbol of the atom

Now,

Atomic number is the number of protons in an atom.

The protons are the positively charged particles in an atom.

For this specie, the positively charged nucleons are 24

What is the bond order for the carbon-nitrogen bond in acetonitrile, CH3CN? 2.2.0 03.0.5 C. 3.0 d. 1.5 0.1.0
marin [14]

Answer:

C. 3.0

Explanation:

Bond order is number of the bonding pairs of the electrons between two atoms.

For CH_3CN,

The total number of the valence electrons  = 2(4) + 1(5) + 3(1) = 16

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,  

The Lewis structure is:

          H

           :                  

H   :    C   :   C   :  :  :   N :

           :

          H

Bond pairs between C and N is 3

<u>So bond pair is 3.</u>

At what substrate concentration would an enzyme with a K_cat of 30.0 s⁻¹ and a Km of 0.0050 M operate at one-quarter of its maxi
Umnica [9.8K]

Answer:

The correct answer is option B.

Explanation:

Michaelis–Menten 's equation:

v=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}

V_{max}=k_{cat}[E_o]

v = rate of formation of products

[S] = Concatenation of substrate = ?

[K_m] = Michaelis constant

V_{max}= Maximum rate achieved

k_{cat} = Catalytic rate of the system

E_o = initial concentration of enzyme

We have :

v=\frac{V_{max}}{4}

[S] =?

K_m=0.0050 M

v=V_{max}\times \frac{[S]}{(K_m+[S])}

\frac{V_{max}}{4}=V_{max}\times \frac{[S]}{(0.0050 M+[S])}

[S]=\frac{0.005 M}{3}=1.7\times 10^{-3} M

So, the correct answer is option B.

How is salinity affected?
Sergio [31]

Answer:

A and E.

Explanation:

 When water evaporates, it leaves the salt. When rain falls, the salt is diluted. The sun causes the  evaporation. The also the sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Also Water travels in a continuous path through Earth called the water cycle. The journey starts in the Earth's oceans. As the Sun heats the ocean, the water evaporates into a gas. The gas meets cooler air, and the gas changes into droplets of tiny water molecules. This process is called condensation. Little droplets of water fall back down to Earth again as precipitation. The precipitation fills up the rivers and various other things and the cycle begins all over again. Now with this being said, there is much more than just this!

     Good luck!
