The answer is that the mold melting point must be higher then molten glass, otherwise the mold would melt when molten glass is poured into it .
I hope this helps :)
Hello Gary My Man!
Well, as you can clearly see
<span>The atomic number of an element is basically the number of protons it has. So yes, for every element this is different. Now, the mass number of an element as known, is the number of protons+the number of neutrons. So theoretically as we can see, this number should be a whole number, but since there are different isotopes (atoms of the same element with different numbers of neutrons) of each element, most periodic tables take account of that, so they often include decimals as seen.
So in Short, ALL</span> the atoms of a particular element have the SAME EXACT atomic number<span> (</span>number<span> of protons of course). The </span>atoms of different elements have very different numbers of protons. And of course, the MASS number of an atom is the TOTAL number as known, of protons and of course, the neutrons it contains in it.
I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Answer:
The empirical formula is N2 CH4 O
Explanation:
The answer & explanation for this question is given in the attachment below.
The theory that describes the motion and force driving earth's plates is Plate tectonics
Explanation:
Plate tectonics states that the outer shell of the Earth is divided into plates that glide and move over the mantle which is the surface of the earth.
The mantle is the rocky inner layer above the core of the Earth.
Plate tectonics helped the geologists to explain how continents could move around the planet.
There are 9 major plate tectonics , namely North American, Pacific, Eurasian, Australian, African, Indo - Australian,Indian South American and Antarctic. These plates have been named after the land form found on them.
