They are slowed down.
even air is a medium and will slow down waves (slightly) compared to a vacuum/ space
if the wave hits the medium at an angle it can be 'bent' (refracted) like light through a glass prism
Answer:
B) PbI2 + 2 KCl
Explanation:
To keep the the law of conservation of matter, the equation given above must be balanced i.e the total element in the reactant must be equal to the total elements in the product.
Given the equation
PbCl2 (aq) + 2 KI (aq) →
At the reactant shown, there are one mole of lead Pb, 2 moles of chlorine Cl, 2moles of Potassium K and 2 moles of Iodine.
During reaction, the Chlorine atom will react with the potassium atom K and the lead atom Pb will react with the iodine atom.
The resulting product that will balance the chemical equation is
PbI2 + 2 KCl
The equation will then become
PbCl2 (aq) + 2 KI (aq) → PbI2 + 2 KCl
If we look at both sides of the equation, we will see that all the elements have the same number of atoms.
Answer:
This situation is possible.
Explanation:
It is said in the problem that one morning two trains are speeding up from opposite directions onto the bridge. It may seem from this statement that the trains are arriving at the same time. But this should be a wrong assumption.
Because it is only said in the problem that the trains are passing the bridge on same morning. No explicit timing is given.
So it may so happen that both the trains pass the narrow bridge on the same morning but at two difeerent times, making no collision with each other.
Answer:
The windward side is that side which faces the prevailing wind (upwind), whereas the leeward, or "lee" side, is the side sheltered from the wind by the mountain's very elevation (downwind)
310.093k.
Given,
Best temperature for enzymes to work = 98.6°F
Unknown :
We need to convert the temperature from fahrenheit to kelvin.
Writing down the equation to be used in the problem's solution correctly:
K = (F x 0.55) + 255.37
F = (K - 255.37) x 1.8
The temperatures are expressed in kelvin (K) and fahrenheit (F), respectively.
There first equation would be significantly more quicker to use :
K = (98.6 x 0.555) + 255.37
= 54.723 + 255.37
= 310.093K
➤ The activity and rate of an enzyme reaction typically increase with temperature, while a decrease in temperature slows the enzymatic reaction. Each enzyme's activity peaks at its individual optimum temperature, and it decreases above and below that point.
