A sample of Neon is in a sealed container held under isothermic conditions. The initial pressure and volume are 2.7 atm and 4.5
Marina CMI [18]

Answer:

The final volume in mL is 7.14 mL or 7.1 mL.

Explanation:

1.Use Boyle's Law(P_{1} V_{1}= P_{2} V_{2}). Re-arrange to solve for V_{2}<em> for the final volume.</em>

<em />

<em>2. Plug in values. </em>V_{2} =\frac{(2.7 atm)(4.5 mL)}{(1.7 atm)}  = 7.14 mL

Which of these compounds has the correct chemical formula? 1. ba3po4 2. (nh4)2so4 3. mg2oh 4. lif2 5. caoh?
sergiy2304 [10]
Ba3PO4 is not neutral, it is positive.  (NH4)2SO4 is neutral, the charges cancel.
Mg2OH is not neutral, it is positive.  LiF2 is not neutral, it is negative.  CaOH is not neutral, it is positive.  The answer is (NH4)2SO4, correct ions will have a neutral charge.

What affects the rates of reactions? describe each. <br> a. <br> b.?
Anvisha [2.4K]
Rates can be calculated with Arrhenius equation k = Axe^(-Ea/RT)
a. temperature affects the rate - imagine you are making coffee, so coffee crystals are boiled faster on higher temperature. Simplified but makes sense.
b. Ea is activation energy. Imagine, while preparing coffee, some of ingredients change to a different one, so there is a A -> B reaction (simplified). Now, Ea is energy barrier that stands on the arrow of this reaction, preventing A to transform to B. If Ea is small, reaction will go easy (not fast!), if Ea is large –reaction will not happen so easy (you ll have to use catalyst for example)
