Answer:
C. Burning wood
Explanation:
BURNING. Burning is a non-reversible chemical change. When you burn wood, the carbon in the wood reacts with oxygen in the air to create ash and smoke, and energy in the form of light and heat. This is a permanent change that cannot be undone – you cannot turn ashes back into wood.
Answer: it is likely soluble in water
It will likely light up a bulb in a conductivity apparatus
It will likely have a high melting point
Explanation:
Answer:
Their amount is not consistent at all parts of the atmosphere
Explanation:
Carbon dioxide and water vapor exists as variable gases in the atmosphere because their amount varies from one part to the other.
- The abundance of variable gases is influenced strongly by activities from the surface.
- This variability occurs a result of the contribution from from life activities on the surface.
- Also, due to properties of the gases, they are not evenly distributed.
- At certain altitudes, the amount of water vapor can be low.
The last step is to calculate the percent by mass of each element in ammonium nitrate (NH4NO3). The masses of the elements in one mole of the compound are: mass N = 28.0 g mass H = 4.0 g mass O = 48.0 g The molar mass of the compound is 80.0 g/mol. What is the mass of one mole of the compound? 80.0g
Answer:
a) I believe it has a volume of 25 ml. I found the value by subtracting 40 from 65.
Hope this Helps!
