Answer:
<h2>1.2 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 30 g
volume= 25 mL
We have

We have the final answer as
<h3>1.2 g/mL</h3>
Hope this helps you
Answer:
E) NaF and SrO
Explanation:
The ionic bonding occurs between atoms with a great difference in electronegativity. This usually happens between a metal and a non-metal.
<em>In which pair do both compounds exhibit predominantly ionic bonding? </em>
A) KCl and CO₂. NO. C and O are non-metals and present covalent bonding.
B) SO₂ and BaF₂. NO. S and O are non-metals and present covalent bonding.
C) F₂ and N₂O. NO. Both compounds contain non-metals and present covalent bonding.
D) N₂O₃ and Rb₂O. NO. N and O are non-metals and present covalent bonding.
E) NaF and SrO. YES. Na and Sr are metals while F and O are non-metals.
Labeled carbon and oxygen, coming from carbon dioxide as source
Plants are autotrophs, which means that they capable of producing their own "food" from inorganic substances using energy from light or chemical reactions. Plants produce their food mainly by photosynthesis, which utilizes energy in the form of sunlight to convert carbon dioxide in the atmosphere to complex organic molecules as source of food.
He was testing an acid. So your answer will be C.
