In one experiment, magnesium metal melts. In a second experiment, magnesium metal ignites as it combines with oxygen. Classify t

joja [24]

Answer:

magnesium metal melts = physical change

magnesium metal ignites = chemical change

Explanation:

Physical changes are those in which the identity of the subtance remains unaltered. No new compounds are formed. They involve generally changes in agreggation states of matter: solid, liquid or gas. The first experiment, in which magnesium metal melts is a physical change because it only changes the state of matter, from solid to liquid, but it is still magnesium metal.

Conversely, chemical changes involve atoms combinations to form new compounds. The second experiment, in which magnesium metal ignites, is a chemical change. After the change, magnesium metal is no longer the metal but a metal oxide.

How many hydrogen atoms are in 709 grams of water? Answer in units of atoms.

zimovet [89]

Answer:

26 Hydrogen atoms

Explanation:

H2O

Each hydrogen atom: 2+16 = 18g

Hence,

1 atom -> 18g

x atoms -> 709g

709/18 = 39 atoms

Therefore, 39 atoms give 709g

Hence, 26 Hydrogen atoms are used

how many grams of nitrogen gas will be formed upon the complete reaction of 30.6 grams ammonium nitrate

artcher [175]

Answer:

5.355 g

Explanation:

first you have 30.6 g from ammonium nitrate ( NH4NO3 )

molecular weight for NH4NO3 is 80 g/mole

and molecular weight for nitrogen gas N2 is 14 g/ mole

make this

NH4NO3 --------------> N2

80 g/mol --------------> 14 g/mol

30.6 g ---------------> x

So X = 14 x 30.6 ÷ 80 = 5.355 g of N2

Good Luck
