Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide: CaO (s) + H 2O (l) → Ca(OH) 2 (s) In a p

Tomtit [17]

Answer:

The answer to your question is: 81%

Explanation:

Data

CaO = 2 g

Ca(OH)₂ = 2.14 g

Reaction balanced

CaO + H₂O ⇒ Ca(OH)₂

Molecular mass

Calcium oxyde = 40 + 16 = 56 g

Calcium hydroxide = 40 + 2 + 32 = 74 g

Process

Rule of three

56 g of CaO -------------- 74 g of Ca(OH)₂

2 g of CaO ------------- x

x = (2 x 74) / 56

x = 2.64 g of Ca(OH)₂

Percent yield

% Yield = $\frac{2.14}{2.64} x 100$

% yield = 81

What is the mass of 5.30×1021 platinum atoms?

DedPeter [7]

<span>(5.08 * 10^21) / (6.022 * 10^23) = 0.0084357 moles * 195.084 g/mol = 1.65 g Atomic mass of platinum = 195.084 g/mol Avogadro's number = 6.022 * 10^23 so here you go</span>

Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?

kherson [118]

To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.
