<span>The law of proportion states that elements combine in whole number ratios. The gram readings for K are multiples of each other, both in grams and moles.
Let us compare the ratios:
</span>2.44 grams/1.22 grams = 2
<span>4.89 grams/2.44 grams = 2</span>
<span>Therefore, Potassium always combines with Oxygen in a ratio of 2 is to 1.</span>
First, we write the reaction equation:
3Pb(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + 3Pb₃(PO₄)₂
Moles of Pb ions present:
moles = concentration x volume
= 0.15 x 0.25
= 0.0375
From the equation,
moles Pb : moles Na₃PO₄
= 3 : 2
Moles of Na₃PO₄:
2/3 x 0.0375
= 0.025
volume = moles / concentration
= 0.025 / 0.1
= 0.25 L
= 250 ml
Answer:

Explanation:
1.5 metres is the length of the tape. Hope this helps :)
Answer:
B.) More intensely
Explanation:
If you immerse a lightstick in hot water, the chemical reaction will speed up. The stick will glow much more brightly but will wear out faster too.
