Reaction will move forward and favor according to Le Chatelier's principle on increasing temperature of water.
According to Le Chatelier's principle, the position of equilibrium will shift if a system in a state of dynamic equilibrium is disturbed by a change in its conditions. The point of equilibrium will shift toward the products to offset the additional reactant if you raise the concentration of one of the reactants. For instance, extra N2 will react with H2 in the system if it is added. More ammonia will be produced as a result of this.
Similar to this, the location of equilibrium would move to the left if you reduced the concentration of one of the reactants. In this instance, removing N2 would cause more NH3 to break down into the reactants.

Answers
Since carbohydrates are essential biomolecules the action of sugars fluctuates when enzymes consume substrates of glucose molecules.
Gas pressure is the pressure created by the collision of gas particles with an object. Inside the balloon, gas particles collide with the inner wall of the balloon. It's these collisions that keep the balloon inflated. When carbon dioxide gas fills the balloon, it inflates. The more gas produced, the bigger the balloon will inflate.
The chemical reaction between baking soda and vinegar will inflate the balloon as long as the baking soda and vinegar react. Force Balance: The pressure inside the inflated balloon is greater than the pressure outside. The balloon is stable because the expansion force due to the pressure difference balances the contraction force due to the surface tension of the rubber.

The pressure 40.0 m under water is 494 kPa. What is this pressure in bar? =
Answers
One kilopascal of pressure is 0.01 bar pressure. Thus 494 kilopascal pressure is 4.94 bar pressure.
What is pressure?Pressure is an intensive quantity measuring the force produced on body by a mechanical stress. Pressure of a substances is inversely proportional to the volume and directly proportional to the temperature.
Pressure of a substance can be expressed in different units where, the SI unit is atm or atmospheric pressure. Other units are bar, pascal, kilopascal etc.
One kilopascal pressure = 0.01 bar. Hence, 494 kilopascal is:
(494 Kpa × 0.01 bar) / 1 kpa = 4.94 bar.
Hence, 494 Kpa pressure is 4.94 bar.

how much will the temperature of 5.00g of silver decrease if it loses 982 j of heat ?
Answers
The temperature of the silver will decrease by -828.7 °C

How do I determine the temperature change?From calorimetry, we understood that heat released or lost is given by:
Q = MCΔT
Where
Q is heatM is the mass C is the specific heat capacityΔT is the temperature change
With the above formula, we can determine the temperature change of the silver. This is illustrated below
Mass of silver (M) = 5.00 gHeat lost (Q) = -982 JSpecific heat capacity of silver (C) = 0.237 J/gºC Temperature change (ΔT) = 124Q = MCΔT
-982 = 5 × 0.237 × ΔT
-982 = 1.185 × ΔT

ΔT = -982 / 1.185
ΔT = -828.7 °C

5.42 mol
* 2 points
Answers
Answer:
A.) 14.75 mol
Explanation:
To find the amount of moles, you need to use the Ideal Gas Law equation:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = Ideal Gas Constant (0.08206 L*atm/K*mol)
-----> T = temperature (K)
You can plug the given values and the constant into the equation and simplify to find "n".
P = 10 atm R = 0.08206 L*atm/K*mol
V = 27 L T = 223 K
n = ? moles
PV = nRT <----- Ideal Gas Law
(10 atm)(27 L) = n(0.08206 L*atm/K*mol)(223 K) <----- Insert variables
270 atm*L = n(18.299 L*atm/mol) <----- Mutliply
14.75 mol = n <----- Divide both sides by 18.299
