Answer:
335,000,000,000,000 Hz
Explanation:
3.35 x 10^14 is just scientific notation. This is a way to make a really big number small to write and easier to understand. The exponent on the 10 represents how many times you move the decimal to the right. If the exponent is negative you should move the decimal to the left. Each time the decimal is moved, and there is no pre-existing number, you need to add a zero.
3.35 x 10^14 is equal to
335,000,000,000,000
Answer:
gives shape and support to the body
Answer:
To increase the yield of H₂ we would use a low temperature.
For an exothermic reaction such as this, decreasing temperature increases the value of K and the amount of products at equilibrium. Low temperature increases the value of K and the amount of products at equilibrium.
Explanation:
Let´s consider the following reaction:
CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)
When a system at equilibrium is disturbed, the response of the system is explained by Le Chatelier's Principle: <em>If a system at equilibrium suffers a perturbation (in temperature, pressure, concentration), the system will shift its equilibrium position to counteract such perturbation</em>.
In this case, we have an exothermic reaction (ΔH° < 0). We can imagine heat as one of the products. If we decrease the temperature, the system will try to raise it favoring the forward reaction to release heat and, at the same time, increasing the yield of H₂. By having more products, the value of the equilibrium constant K increases.
because since there are now 4 electrons(-) you can tell that it had 4 protons (+) before so -4+4 is 0 which makes it neutral. hope it helps.
