Answer:

Double replacement

Precipitation reaction

Explanation:

You have the reaction:

         REACTANTS                          PRODUCTS

BaCl₂ (aq) + Na₂SO₄ (aq) ⇒ 2NaCl (aq) + BaSO₄(s)

The general form of a double replacement reaction is the following:

AB + CD ⇒ CD + AB

The reactants basically, exchanged partners. In the case of your problem, Barium(Ba) and Sodium(Na) switched places. So this makes it a double-replacement reaction.

Now how do I know it is a precipitation reaction. A precipitation reaction occurs when two solutions combine and salt is formed. Salt is solid, so how do I know that's what occured? Look at your equation again:

BaCl₂ (aq) + Na₂SO₄ (aq) ⇒ 2NaCl (aq) + BaSO₄(s)

aq means aqueous (liquid)

s means solid

If you look at the product formed in the reaction, from two solutions, it formed a solid. So this is your clue as to why it is a precipitation reaction.

Complete this equation for the dissociation of na2co3(aq). omit water from the equation because it is understood to be present.
Elanso [62]
Note that we are omitting the water.

So, sodium carbonate will basically dissociate into positive sodium ions and negative carbonate ions based on the following equation:
 <span>Na2CO3 → 2 Na(+) + CO3(2-)
</span>
If we took water into consideration:
Sodium carbonate will dissociate in water forming carbonic acid and sodium hydroxide. Since sodium hydroxide is a strong base, therefore, it will then neutralize the gastric acid, thus, acting as an antacid.

You need 4.0 ounces of a steroid ointment. if there are 16 oz in 1 lb, how many grams of ointment does the pharmacist need to pr
Bond [772]

The given units are the units of masses which are interconvertable.

It is given that:

1 lb = 16 oz

Now, converting kg to lb:

Since, 1 kg = 2.20462 lb

So, \frac{0.0625 lb}{1 oz}\times \frac{1 kg}{2.20462 lb}

Now converting kg to g:

Since, 1 kg = 1000 g

So, \frac{0.0625 lb}{1 oz}\times \frac{1 kg}{2.20462 lb}\times \frac{1000 g}{1 kg} = 28.349 \frac{g}{oz}

For 4 oz:

28.349\frac{g}{oz} \times 4 oz = 113.396 g

Thus, 113.396 g of ointment needed to be prepared by the pharmacist.

A discus thrower throws a 1.6kg discus at 25m/s what's the kinetic energy?​
Ilya [14]

Answer:

<h2>500 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2} \\

where

m is the mass

v is the velocity

From the question

m = 1.6 kg

v = 25 m/s

We have

k =  \frac{1}{2}  \times 1.6 \times  {25}^{2}  \\  = 0.8 \times 625 \\  = 500

We have the final answer as

<h3>500 J </h3>

Hope this helps you
