Answer:
The answer to your question is a) 70 moles of CO₂
b) 67.2 moles of CO₂
Explanation:
Data
moles of C₂H₂ = 35
moles of O₂ = 84
Balanced chemical equation
2C₂H₂ + 5O₂ ⇒ 4CO₂ + 2H₂O
Process
1.- Moles of CO₂
2 moles of C₂H₂ ------------------- 4 moles of CO₂
35 moles of C₂H₂ ------------------- x
x = (35 x 4)/2
x = 70 moles of CO₂
2.- Moles of CO₂
5 moles of O₂ ----------------------- 4 moles of CO₂
84 moles of O₂ ----------------------- x
x = (84 x 4) / 5
x = 67.2 moles of CO₂
Answer:
Mass = 1080.26 g
Explanation:
Given data:
Number of moles of LaPO₄ = 4.56mol
Mass in gram = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of LaPO₄ = 236.9 g/mol
by putting values,
4.56 mol = mass/ 236.9 g/mol
Mass = 4.56 mol × 236.9 g/mol
Mass = 1080.26 g
A reaction that creates larger molecules from substrates and results in water as a byproduct would be catalyzed by a<u> </u><u>synthase</u> enzyme.
<h3>What is synthase?</h3>
Synthase is an enzyme that catalyzes the synthesis of new compounds in the body. As a result, it is a very widespread enzyme that can be found in both higher and lower-order species. Synthases do not use energy from nucleoside triphosphates.
A synthase is a ligase that joins two chemicals or compounds together with the need for energy, whereas a synthase is a lyase that catalyzes the breakage of numerous chemical bonds through methods other than hydrolysis and oxidation.

When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall. Therefore, that part of the wall is left repelled.
<u>Explanation</u>:
- Balloons don't stick to walls. However, if you rub the balloon on an appropriate piece of material such as clothing or a wall, electrons are pulled from the other material to the balloon.
- The balloon now as more electrons than normal and therefore has an overall negative charge. Two balloons like this will repel each other.
- The other material now has an overall positive charge. Because opposite charges attract, the balloon will now appear to stick to the other material. If you didn't rub the balloon first, it's charge would be neutral and it wouldn't stick to the wall.
If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.
