Answer:
El motor que las permite vencer la gravedad es la evaporación del agua que tiene lugar en las hojas.
Explanation:
Density = Mass / Volume
Density = 2.0g / 5.0ml
Density = 0.4 g/ml
We can find out how acidic or basic a substance is by using the pH scale. The greater the pH number is, the more basic the substance is. In order to convert from pOH to pH, we can use the equation pH = 14 - pOH. Our new pH values are then solution A = 12.5, solution B = 7.0, and solution C = 0.5. The answer is then solution A, because it has the greatest pH value.
Hope this helps!
Answer: Wind, in climatology, the movement of air relative to the surface of the Earth. Winds play a significant role in determining and controlling climate and weather.
Answer:
2Na⁺ (aq) and 2OH⁻(aq)
Explanation:
Spectator ions:
Spectator ions are those ions which are same on both side of chemical reaction. These ions are same in the reactant side and product side. Their presence can not effect the chemical equilibrium that's why when we write the net ionic equation these ions are neglect or omitted.
Given ionic equation:
Ba⁺²(aq) + 2OH⁻(aq) + 2Na⁺ (aq) + CO²⁻₃(aq) → BaCO₃(s) + + 2Na⁺ (aq) + 2OH⁻(aq)
In given ionic equation by omitting the spectator ions i.e, 2Na⁺ (aq) and 2OH⁻(aq) net ionic equation can be written as,
Net ionic equation:
Ba⁺²(aq) + CO²⁻₃(aq) → BaCO₃(s)
