Answer:
The concentrations of the products and reactants do not change
Explanation:
A system is said to be in equilibrium when there is no observable change in concentration of the reactants and products with time.
However, a dynamic equilibrium occurs when the rate of the forward and backward reaction are the same. This implies that the concentration of the reactants and products do not change as long as the physical state of the system is kept constant.
Answer:
1.The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s. 2. An engineer has devised a way to stop Arctic ice from melting by scattering millions of tiny glass beads to reflect sunlight away. Scientists have discovered that melting in Greenland and Antarctica is occurring much faster than they previously thought. 3. The cap of sea ice covering the Arctic Ocean started to shrink when it should have been growing. Temperatures at the North Pole soared more than 20 °C above normal at times. And polar bears prowling the shorelines of Hudson Bay had a record number of run-ins with people while waiting for the water to freeze over. In the span of a few months, all manner of strange things happened. 4. Human basic needs, such as food, water, health, and shelter, are affected by climate. Changes in climate may threaten these needs with increased temperatures, sea level rise, changes in precipitation, and more frequent or intense extreme events. Climate change will affect individuals and groups differently.
Explanation:
Answer:
Pb(s)------>Pb2+(aq)
Explanation:
If you look at the oxidation numbers Pb increases from 0 to +2 while Cu decreases from +2 to 0.Hence,Pb is the reducing agent and Cu2+ is the oxidizing agent.
Also, a thing to note is that the oxidation number of any solid is always 0.

Answer:
When experiments are carried out or research is done in a certain field of knowledge the scientist at first hypothesise certain knowledge or make theoretical hypotheses about that field of knowledge.
And then conduct the experiment or research to derive certain conclusions and get answers which they can apply on the hypothesis made or on the previous knowledge they have and thereby confirm or negate the hypothesis.
When two scientists are working on similar experiment and they tend to differ in the conclusions drawn by the result, as they get from experiment then it is called as confirmation bias among the scientists.
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element.
