<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>

Answer:
Average temperatures in July range from 85°F to 90°F during the day but cool off quickly after dark, dropping into the 50s and 60s (°F). Some regions of Wyoming are classified as desert, so there isn't much precipitation. Most of it falls as rain in the late spring and early summer, which is also a windy time of year.
Explanation:idk if this helps awnser ur question
Answer:
This is a pretty straightforward example of how an ideal gas law problem looks like.
Your strategy here will be to use the ideal gas law to find the pressure of the gas, but not before making sure that the units given to you match those used by the universal gas constant.
So, the ideal gas law equation looks like this

Here you have
P
- the pressure of the gas
V
- the volume it occupies
n
- the number of moles of gas
R
- the universal gas constant, usually given as
0.0821
atm

L

K
T
- the absolute temperature of the gas
Take a look at the units given to you for the volume and temperature of the gas and compare them with the ones used in the expression of

The answer is rounded to two sig figs, the number of sig figs you have for the temperature of the gas.
Answer:
The answer to this question is B
At least Im pretty sure
In a Punnett square, lower case letters are recessive alleles and upper case letters are dominant alleles. So, "tt" would mean that both alleles are recessive. In comparison, "Tt" would mean that one allele is dominant and one is recessive. Therefore zero would be tall as their is no T trait from either parents.
