Answer:
I'm gonna say igneous
Explanation:
The texture looks rough and the rock looks like it's composed of different types of minerals making it an igneous rock
I hope this helps :)
<u>Answer:</u>
<em>0.264 g of 
can be formed from 288 mg of 
</em>
<u>Explanation:</u>
The balanced chemical equation is
The conversions are
Mass in mg is converted to mass in g
Mass in g is converted to moles by dividing with molar mass
Moles is converted to moles by using the mole ratio of 
is 9 : 6
Moles is converted to mass by multiplying with molar mass
mass in mg > mass in g >moles > moles > mass
=0.264g (Answer)
Answer:
Y Q W Z X
Explanations:
The most reactive element is the element that will displace an element from it compound . The most reactive element will replace the less reactive element in it compound.
Q+ + Y Reaction occurs
Since the reaction occurs the element Y which is more reactive displaced element Q from it compound.
Q+W+ Reaction occurs
The reaction occurs, that means element Q replaces element w from it compound. Element Q is therefore more reactive than element W.
W+Z+ Reaction occurs
The reaction also occurs . This is an indication that element W replaces element Z in it compound. This means element W is very reactive than element Z.
X+Z+ No reaction
There is no reaction here. This is an indication that element X is less reactive than element Z. This is why element X can't displace element Y in it compound.
The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %
