Answer:
Explanation:
Potassium ion will be formed when potassium atom loses one electron to become positively charged
K₁₉ →→ K₁₉⁺ + e⁻
Bromine ion is formed by gain of electron
Br₃₅ + e⁻ → Br₃₅⁻
Answer:
Option A. Dense water floats.
Explanation:
Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.
However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.
The question is incomplete, the complete question is;
1. Given: 2A(g) <-> 2B(g) + C(g). At a particular temperature, K = 1.6x104.
At a higher temperature, K = 1.8x10-5. Placing the equilibrium mixture in an ice bath (thus lowering the temperature) will...
cause [A] to increase
cause [B] to increase
gave no effect
cannot be determined
Answer:
cause [B] to increase
Explanation:
We have to have it behind our minds that; for an exothermic reaction, when the temperature is increased, the value of the equilibrium constant decreases. On the other hand, for an endothermic reaction, increasing the temperature increases the value of the equilibrium constant.
In this particular case, increasing the temperature decreased the equilibrium constant from K = 1.6x104 to K = 1.8x10-5 meaning that the equilibrium constant decreased with increase in temperature. This means that the reaction is exothermic and a decrease in temperature will favour the forward reaction hence more B is produced.
Answer:
True! A transverse wave does move a medium at an obtuse angle to the wave!!
Answer:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
