Explanation:
Took the test and it was right. :)
Answer:
The pressures will remain at the same value.
Explanation:
A catalyst is a substance that alter the rate of a chemical reaction. It either speeds up the or slows down the rate of a chemical reaction.
While a catalyst affects the rate, it is noteworthy that it has no effect on the equilibrium position of the chemical reaction. A catalyst works by creating an alternative pathway for the reaction to proceed. Most times, it decreases the activation energy needed to kickstart the chemical reaction.
Hence, we know that it has no effect on the equilibrium position. Factors affecting equilibrium position includes, temperature and concentration of reactants and products( pressure in terms of gases).
The reactants and the products here are gaseous, and as such pressure affects the equilibrium position. Now, we have established that the equilibrium position is unaffected. And as such the pressure affecting it does not change.
Thus, we have established that the pressure of the products and reactants are unaffected and as such they remain at their value unaffected.
Explanation:
the answer is C- H2O (water)
Answer:
Explanation:
To find the number of moles of each element present in 1 mole of Be(OH)₂, we use the ratio of the molar masses of the elements to the compound and multiply by the given mole.
Molar mass of Be(OH)₂ = 9 + 2(16+1) = 43g/mol
number of moles of Be = 
x 1 = 0.209mole
number of moles of O = 
x 1 = 0.744mole
number of moles of H = 
x 1 = 0.047mole
For 2 it’s 2ft 10in
For 5 it’s 3ft 6in
You: put how tall you are
Adult: you can either measure an adult or use this 5 ft 10in
