he mass defect of the helium nucleus ⁴He₂ is 0.030377 u

Further explanation

Mass defect means the difference between the mass of particles forming an atom with an atomic mass.

Δm = mass defect ( u )

mp = mass of proton ( u )

me = mass of electron ( u )

mn = mass of neutron ( u )

M = atomic mass ( u )

A = mass number

Z = atomic number

Let us now tackle the problem !

Given :

Unknown :

Δm = ?

When forming ions, nitrogen will gain or lose how many electrons, forming a cations or anions with a what charge?
Ann [662]

Answer:

Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.

Help it’s due right now I will give you 15 points or more
cupoosta [38]

Answer:

1. Temperature,  the average kinetic energy of particles, indicates how warm something is. Thermal energy, or the overall kinetic energy of the particles, indicates how a substance or material will transmit heat or chill something else.

2. A thermal expansion is a matter to change in volume in response to a change in temperature.

3. Heat is the form of energy that is transferred between systems or objects with different temperatures.

4. Air temperature near or over bodies of water is much different from that over land due to differences in the way water and land heat and cool. Properties that affect water temperature are transparency, ability to circulate, and specific heat.

5. Radiation is the transfer of heat energy through space by electromagnetic radiation.

6.  Radiation is natural and found everywhere, it comes from outer space, the air we breathe, and the earth we tread.

7. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. The fluid above a hot surface expands, becomes less dense, and rises.

8. Convection currents in the Earth occur in the mantle

9. The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.

10. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

- Hope this helps!

Why do you move the .0100 - x to the left side of the equal sign?
dlinn [17]
Because negatives are on the left and positives are on the right , if it was .0100 +x it would move to the right since +x implies that the x is positive.
