Answer:</h3>
= 633,600 Inches
<h3>
Explanation:</h3>
Speed refers to the rate of change in distance traveled by a body in motion.
It is the ratio of distance to time taken.
It is calculated by;
Speed = Distance ÷time taken
Therefore;
Distance = Speed × time
In this case;
Time taken = 12 minutes ( but 1 hr = 60 mins)
Thus, t = 0.2 hours
Speed = 50.0 miles/hour
Thus;
Distance = 50.0 miles/hr × 0.2 hours
= 10 miles
But, we are require to give the distance in inches;
1 mile = 63360 Inches
Therefore;
10 miles = 10 × 63360 Inches
= 633,600 Inches
Answer:
Explanation:
For a general equilibrium
aA +bB ⇔ cC + dD ,
the equilibrium constant is K = [C]^c [D]^d / [A]^a[B]^b.
Our reasoning here should be based on the fact that Q has the same expression as K, but is used when the system is not at equilibrium, and the system will react to make Q = K to attain it ( Le Chatelier´s principle ).
So with this in mind, lets answer this question.
1. False: Q can large or small but is not the value of the equilibrium constant, it will predict the side towards the equilibrium will shift to attain it.
2. False: Given the expression for the equilibrium constant, we know if K is small the concentrations of the reactants will be large compared to the equilibrium concentrations of the products.
3. False: when the value of K is large, the equilibrium concentrations of the products will be large and it will lie on the product side.
4. True: From our previous reasongs this is the true one.
5. False: If K is small, the equilibrium lies on the reactants side.
Answer:
0.1313 g.
Explanation:
- It is known that at STP, 1.0 mole of ideal gas occupies 22.4 L.
- Suppose that hydrogen behaves ideally and at STP conditions.
<u><em>Using cross multiplication:</em></u>
1.0 mol of hydrogen occupies → 22.4 L.
??? mol of hydrogen occupies → 1.47 L.
∴ The no. of moles of hydrogen that occupies 1.47 L = (1.0 mol)(1.47 L)/(22.4 L) = 6.563 x 10⁻² mol.
- Now, we can get the no. of grams of hydrogen in 6.563 x 10⁻² mol:
<em>The no. of grams of hydrogen = no. of hydrogen moles x molar mass of hydrogen</em> = (6.563 x 10⁻² mol)(2.0 g/mol) = <em>0.1313 g.</em>
The answer is 1.6 atm. I just took the quiz.
