Answer:
The four coefficients in order, separated by commas are 1, 8, 5, 6
Explanation:
We count the atoms in order to balance this combustion reaction. In combustion reactions, the products are always water and carbon dioxide.
C₅H₁₂ + ?O₂→ ?CO₂ + ?H₂O
We have 12 hydrogen in right side and we can balance with 6 in the left side. But the number of oxygen is odd. We add 2 in the right side, so we have 24 H, and in the product side we add a 12.
As we add 2 in the C₅H₁₂, we have 10 C, so we must add 10 to the CO₂ in the product side.
Let's count the oxygens: 20 from the CO₂ + 12 from the water = 32.
We add 16 in the reactant side. Balanced equation is:
2C₅H₁₂ + 16O₂→ 10CO₂ + 12H₂O
We also can divide by /2 in order to have the lowest stoichiometry
C₅H₁₂ + 8O₂→ 5CO₂ + 6H₂O
Sodium hydrogen carbonate is a weak base because it is not a water soluble hydroxide.
Answer:
I believe the carts will move towards each other, as positive and negative charges attract each other.
Explanation:
It is like a magnet when you put the opposite sides together. (North and South, South and North) or the plus goes to the minus and the minus goes to the plus.
If you take out the far left and right wedges, it may move a little away for a few seconds, but will move back together .
Another hypothesis is that if the sheets are flimsy, the sheets will attract each other, however, the sheets will join together at the top, but the carts will still stay at the same place.
The environmental conditions of the ocean are:
- Light availability
- Oxygen levels
- Water movement
- Salinity
- Density and
- pH.
<h3>What are the environmental impacts on the ocean?</h3>
In our oceans, there are known to be a lot of environmental conditions that are known to often affect the growth, survival and also the productivity of marine organisms. These are the ones listed above.
Note that the increased concentration of chemicals, e.g. nitrogen and phosphorus is one that can be harmful to marine life.
Hence, The environmental conditions of the ocean are:
- Light availability
- Oxygen levels
- Water movement
- Salinity
- Density and
- pH.
