How many moles of HNO3 are present if 4.90×10−2 mol of Ba(OH)2 was needed to neutralize the acid solution?
Amiraneli [1.4K]

Answer:

0.098 moles

Explanation:

Let y represent the number of moles present

1 mole of Ba(OH)₂ contains 2 moles of OH- ions.

Hence, 0.049 moles of Ba(OH)2 contains y moles of OH- ions.

To get the y moles, we then do cross multiplication

1 mole *  y mole = 2 moles * 0.049 mole

y mole = 2 * 0.049 / 1

y mole =  0.098 moles of OH- ions.

1 mole of OH- can neutralize 1 mole of H+

Therefore, 0.098 moles of HNO₃ are present.

Explain how the digestive/excretory system is similar to a recycling center
CaHeK987 [17]

Answer:

The digestive system is a system where our body breaks down food to acquire important nutrients. This is the same as your local recycling center because they collect and breaks the plastic down to be reused into recycled products.

The excretory system is a system where we remove excess unnecessary materials. This can be the same as the recycling center because they remove unnecessary materials (such as trash that is not meant to be recycled).

How much heat must be removed from 15.5 g of water at 90.0°C to cool it to 43.2°C?
Katyanochek1 [597]

Answer:

Heat, Q = 3035.073 J

Explanation:

It is given that,

Mass of water, m = 15.5 g

Initial temperature, T_i=90^{\circ} C

Final temperature, T_f=43.2^{\circ}

The specific heat of water is, c = 4.184 J/ g°C

The heat removed or absorbed by water is given by formula as :

Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\Q=15.5\times 4.184\times (43.2-90)\\\\Q=-3035.073\ J

So, the heat of 3035.073 J is removed from 15.5 g of water.
