I’m pretty sure you just balance it out

Sophie [7]

Answer:

22.13g

Explanation:

We'll begin by writing a balanced equation for the reaction. This is illustrated below:

2C2H2 + 5O2 —> 4CO2 + 2H2O

Next, we'll calculate the mass of C2H2 and O2 that reacted from the balanced equation. This is illustrated below:

Molar Mass of C2H2 = (12x2) + (2x1)

= 24 + 2 = 26g/mol

Mass of C2H2 that reacted from the balanced equation = 2 x 26 = 52g

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 that reacted from the balanced equation = 5 x 32 = 160g

Now, we can obtain the mass of C2H2 that will react with 68.1g of O2 as follow:

From the balanced equation above,

52g of C2H2 reacted with 160g of O2.

Therefore, Xg of C2H2 will react with 68.1g of O2 i.e

Xg of C2H2 = (52x68.1)/160

Xg of C2H2 = 22.13g

Therefore, 22.13g of C2H2 is needed to react with 68.1g of O2

What tests would you use to identify a solution of fecl3

lisov135 [29]

Answer:

A flame test of a colorless solution gives a bright yellow color. When reacted with AgNO, a white precipitate forms that dissolves when HNO, is added.

The atomic mass of carbon is 12.01, hydrogen is 1.01, and oxygen is 16.00. What is the molar mass of glucose (C6H12O6)?

kotykmax [81]

To find out the molar mass, you have to break down each of the elements, then add them up.

C6 = 12.01 x 6 = 72.06 (Beacause, there are 6 carbon atoms)
H12 = 1.01 x 12 = 12.12 (Because, there are 12 hydrogen atoms)
O6 = 16.00 x 6 = 96 (Because there are 6 oxygen atoms)

Now, you will add all three of the elements up: 72.06 + 12.12 + 96 = 180.18.

So the molar mass of glucose is 180.18.

lara31 [8.8K]

Answer:

(iii) A has pH greater than 7 and B has pH less than 7

Explanation:

Phenolphthalein is a common indicator in acid base titrations. It turns pink in basic conditions and turns colorless in acidic conditions. Thus on addition of solution A it becomes pink so A should be basic having pH more than 7. On addition of B , it turn out to be colorless means that B is an acidic solution having pH less than 7.
