A little aluminum boat (mass of 14.50

Chemistry
1 answer:
Valentin [98]3 years ago
5 0
When the volume is 450 cm3 so the boat will displace 450 g.

so we have  450 g - 14.5g = 435.5 left 

so to get how many pennies can be added to the boat before it sinks can be determined by:

divided the mass for the one penny:

no.of Penny = 435.5 / 2.5g

                     = 174.2 

∴ the boat will float with 174 pennies and will start to sink with 175

What is the pH of 0.0001 M NaOH
kow [346]
Well. NaOH is a base. That's the first thing you need to watch for.
So to find the pOH, you take -log(.0001)
that would be 4. So now you have the pOH and <u>you still need to find the pH
</u>To find pH from pOH, you take 14(the maximum pH,sorta)-pOH(in this case 4)
14-4=10 The pH of NaOH is 10

What is the balanced chemical equation for the word equation below?
ladessa [460]

Answer:

4Fe + 3O₂ → 2Fe₂O₃

Explanation:

Fe → ²⁺

O → ²⁻

But Iron III is Fe³⁺

So we have Fe³⁺ and O²⁻, the formula for the oxide must be Fe₂O₃ so the equation can be:

4Fe + 3O₂ → 2Fe₂O₃

A reaction produces 10.5 L if oxygen, but was supposed to produce 1 mol of oxygen. What is the percent yield ? (One mole of any
Rzqust [24]
To answer this item, we assume that oxygen behaves ideally such that it is able to fulfill the following equation,

 PV = nRT

If we are to retain constant the variable n and V. 

The percent yield can therefore be solved through the following calculation,

   n = (10.5 L)/(22.4 L)   x 100%

Simplifying,
    n = 46.875%

Answer: 48.87%
