Answer:
Answer in explanation
Explanation:
A. Heating the mixture
Before we can explain the effect of a temperature increase, we need to know the type of reaction it is on temperature basis. As heat is produced, this type of reaction is an exothermic reaction. An exothermic reaction is one in which heat is released into the environment. As such, increasing the temperature of an exothermic reaction leads to more reactants being formed. The equilibrium will thus favor the backward reaction
B. Adding an excess of carbon monoxide
This means we are adding more reactants to the mix. This causes an increase in the available reactants necessary for the reaction to take place making it possible for more product to be formed. This thus favors the forward reaction
C. Removing the methanol as it is formed also favors the forward reaction. This favors the forward reaction as there is allocation for more product to be formed
D. Adding a substance that reacts with carbon ii oxide means less reactant availability which makes it possible for the equilibrium to favor the backward reaction as less reactant is available to give more product.
kg and all the given units are units used to measure mass.
kg is the standard unit to measure mass
lets find the value of 0.00684 kg in all the given units
a. dkg
1 kg is equivalent to 100 decagram (dkg)
therefore 0.00684 kg is = 100 dkg/kg x 0.00684 kg = 0.684 dkg
this is not the given value therefore this choice is incorrect
b. 1 kg is equivalent to 1000 g
therefore 0.00684 kg = 1000 g/kg x 0.00684 kg = 6.84 g
this is the given value so this is correct
c. 1 kg is equivalent to 100 000 centigrams (cg)
therefore 0.00684 kg = 100 000 cg/kg x 0.00684 kg = 684 cg
this is the given value so this is also correct
d) 1 kg is equivalent to 1 000 000 mg
therefore 0.00684 kg = 1 000 000 mg/kg x 0.00684 kg = 6 840 mg
this too is correct
the incorrect answer is A. 0.0684 dkg
Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.
Answer:
Explanation:
Hello,
In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
Whereas we are asked to compute the moles given the temperature in Kelvins, thr pressure in atm and volume in L as shown below:
