Answer:
a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.
Explanation:
A lead pipe is a pipe that's made of lead and is usually used in distribution of potable water to connect a water main source to a user's preferred area.
Now, a copper pipe can't simply be welded directly to a lead pipe because lead has a far lower melting point than copper and thus the lead will melt before the copper can even be effected.
Lead has a melting point of 327.5° C while copper wire has a melting point of 1082.778 °C
Answer:
Explanation:
The given equation is not correctly balanced. However the number of each type of atoms on right side are,
Mg = one magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = two chlorine atoms
Chemical equation.
MgS + CuCl₂ → CuS + MgCl₂
Balance chemical equation:
2MgS(aq) + 2CuCl₂(aq) → 2CuS(s) + 2MgCl₂(aq)
In case of balance chemical equation number of each type of atoms on right side are,
Mg = two magnesium atom
S = two sulfur atom
Cu = two cuppor atoms
Cl = four chlorine atoms (because two chlorine atom form one chlorine molecule)
Answer:
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom.
When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
what does radiation do?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom
Tonga Trench is convergent.
- In the western Pacific Ocean, there is a trench known as the Tonga Trench. It is the second-deepest trench on Earth after the Mariana Trench and the deepest in the Southern Hemisphere.
- The Tonga Trench was created millions of years ago by a process known as subduction, in which two tectonic plates collide and push one under the other.
- The Tonga Trench is 850 miles long and typically reaches depths of 20,000 feet.
- From the southwest corner of the Kermadec Plate to the northwest point of the Tonga Plate, there is a convergent plate boundary known as the Kermadec-Tonga subduction zone.
- The Tonga Trench's Horizon Deep, located at 23.25833°S 174.726667°W, is its deepest point.
- There are numerous volcanoes in the Tonga Trench, both active and dormant, and it is prone to earthquakes and tsunamis.
