Answer:
a party mix:-) it would be a jar of cashews, peanuts, almonds, ettc.
Explanation:
if you can separate the nuts, it is heterogenous
The overall order of a reaction is directly
related to the reaction mechanism of the reaction. The reaction mechanism is
defined by the reaction rate equation. In this case, we are given by the
equation, Rate=k. The order of this reaction is zero since the rate is
not dependent on the concentration of reactants or products.
Answer:
C. 33.6L
Explanation:
Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.
To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:
<em>Moles H2:</em>
3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced
<em>Volume:</em>
PV = nRT
V = nRT / P
<em>Where P is pressure = 1atm at STP</em>
<em>V is volume = Our incognite</em>
<em>n are moles of the gas = 1.50 moles</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 273.15K</em>
<em />
V = nRT / P
V = 1.50mol*0.082atmL/molK*273.15K / 1atm
V = 33.6L
<h3>C. 33.6L</h3>
Answer 1:
This is an example of successful adaptive mutation. Adaptive mutations actually happen because of high levels of stress in the organism's environment caused by the same stressor/s. Here, lots of rabbits being excessively cold all the time due to environment changes caused a lot of extra stress and over time, they successfully mutated to adapt to their environment.
Answer 2:
The answer should be the 4th one. A mutation that doesn't work doesn't always fully go away, but it will become much less common.
