How many grams of water are produced if we react 3 moles of hydrogen with 3 moles of oxygen?

Chemistry
1 answer:
Thepotemich [5.8K]2 years ago
4 0

Answer:

About 60 grams

Explanation:

The balanced equation of the reaction is given as;

2H2(g) + O2(g) → 2H2O(l)

From the equation;

2 mol of H2 reacts with 1 mol of O2

3 mol of H2 would require 3/2 mol of O2 (considering the 2:1 ratio)

The limiting reactant is H2 as it would be used up before H2. It determines the amount of product that would be formed.

2 mol of H2 produces 2 mol of H2O

3 mol of H2 would produce 3 mol of H2O (Considering the 1 : 1 ratio)

Converting moles to mass;

Mass = Molar mass * Number of moles

Mass = 18 * 3 = 54 g

The correct option is; About 60 grams

Answer:

(1) atomic numbers

Explanation:

The observed regularities in the properties of the elements on the periodic table are periodic functions of their atomic numbers.

  • Atomic number is the number of protons in an atom.
  • The periodic law states that "the properties of elements are a periodic function of their atomic number".
  • Elements on the periodic table are arranged based on the atomic numbers they contain.
  • The number of positively charged particles in an atom is the atomic number.

The average adult heart pumps about 84. mL/s of blood at 72 beats per minute. Suppose you need to calculate how long it would ta
s2008m [1.1K]

Answer:

63.1 seconds.

Explanation:

Hello!

In this case, since the average adult heart pumps 84.0 mL/s of blood, it means 84.0 mL each second, as we have 5300. mL, the following mathematical set up help us to compute the required time:

t=5300.mL*\frac{1s}{84.mL}\\\\t=63.1s

Which is about 1.05 min.

Best regards!

What is the mass , in grams of 0.0287 moles of sucrose
VladimirAG [237]

Hey there!

Sucrose is C₁₂H₂₂O₁₁.

Find molar mass of sucrose:

C: 12 x 12.01 = 144.12

H: 22 x 1.008 = 22.176

O: 16 x 11 = 176

--------------------------------

                  342.296 grams

That is the mass of one mole of sucrose.

We have 0.0287.

342.296 x 0.0287 = 9.82

The mass of 0.0287 moles of sucrose is 9.82 grams.

Hope this helps!

How many grams of BaCl2 are required to make 1.50L of a 0.60M solution?
masha68 [24]

Answer:

187.407g

Explanation:

Moles of solute = Molarity × Liters of solution

Multiply 0.60 M by 1.50L:

0.60 mol/ 1L×1.50L=0.9 mol

To obtain the mass of solute, we will need to the molar mass of BaCl2, which is 208.23g/mol:

Finally, multiply the number of moles by208.23g /mol

0.9mol×208.23g/1mol =187.407g

Boom, you have a mass of:

187.407g
