Answer:

They have the same number of atoms. = YES

They have different masses. = YES

Explanation:

1 mol of beryllium

• 1 mol of salt

beryllium = Be = Atomic mass: 9.012182

salt = NaCl = Molar mass: 58.44 g/mol

1 mol of water

• 1 mol of hydrogen

water = H2O = Molar mass: 18.01528 g/mol

hydrogen = H = 1g/mole

Which statement is true about these substances?

They have exactly the same mass. = NO

They have different numbers of particles = NO

They have the same number of atoms. = YES

They have different masses. = YES

Avogadro constant means the number of units in one mole of any substance (defined as its molecular weight in grams) is equal to 6.02214076 × $10^{23}$ .

Which type of reaction?

polet [3.4K]

condensation polymerization, since a byproduct of the reaction is a single molecule of water (hence condensation of water)

addition polymerization is if you add the two polymers together like blocks and should have no byproducts

esterification is when you combine an organic acid with an alcohol. Since neither of the two polymers look like acids, you can rule this out.

never heard of saponification, Im an mechanical engineer not an organic chemist

The chief advantage of the metric system over other system of measurement is that it

kolbaska11 [484]

Answer:

The metric system goes by powers of ten, so it's very easy to measure. That would be the main advantage, measurements of ten. We can also say it's the most used measurement around the world, so all scientists have little to no conversion, but the main answer is probably the first one :)

a magnet has a north and south pole labeled in the drawing student A thinks that if you cut a magnet in half each ew parts will

riadik2000 [5.3K]

Answer:

The student is Incorrect

Explanation:

Even if you break a magnet the poles still remains same. There is no

difference in the magnet Both north and south pole will be there even if you

cut it in to small pieces when you cut it into pieces, if suppose you break 2

magnets and put north and north together it will repel whereas if there are

different poles like north and south it will attract, so even if you break one

single magnet the different poles will attract, Hence the student is incorrect.
