2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.

Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!

Answer:

The formula for the salt formed is Ca(HPO4)

Explanation:

When an acid reacts with a base, there is a salt formation. Sometimes the replacement of the hidrogens in the acid by the cation of the base is complete, and sometimes there is a partial replacement,as in the presente case. Here, the cation of the base is Ca2+ and it will reacts with the anion HPO4- of the acid.

H3PO4 + Ca(OH)2 ⇒ Ca(HPO4) + 2H2O

As you can see, water is also formed as a product of the reaction.

Summarizing, the formula for the salt formed is Ca(HPO4)

Rob measures the solubility of three different salts in water at 22°C. Which type of graph should he use to display his data?. b

sveta [45]

To present his data on the <span>solubility of three different salts in water at 22°C, bar graph should be used since there are different salts and the only variable is the type of salt used. Line graph and scatter plot use two coordinates or variables and is common to comparing data using the same sample while using histogram to find out data distribution is irrelevant.</span>

Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, and the average height of the falls is about 50 m. Knowing

Andre45 [30]

Answer:

Power, $P=1.176\times 10^9\ W$

No of bulbs = 78400000

Explanation:

We have,

Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, it mean it is mass per unit time i.e. m/t.

It falls from a height of 50 m

The gravitational potential energy of falling water is given by :

P = mgh

Power is equal to the work done divided by time taken. So,

$P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{m}{t}\times gh$

So,

$P=2400000\times 9.8\times 50\\\\P=1.176\times 10^9\ W$

Let there are n bulbs that could power 15 W LED. It can be calculated by dividing the power by 15. So,

$n=\dfrac{1.176\times 10^9}{15}\\\\n=78400000\ \text{bulbs}$

It means that the number of bulbs are 78400000.

The reaction AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) is a(n) ______________ reaction.

Temka [501]

Answer : The correct option is, (e) precipitation reaction

Explanation :

Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Precipitation reaction : It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined.

The insoluble salt that settle down in the solution is known an precipitate.

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

In this reaction, A is more reactive element and B is less reactive element.

Acid-base reaction : It is defined as the reaction in which an acid react with a base to give salt and water as a product.

The given chemical reaction is:

$AgNO_3(aq)+NaCl(aq)\rightarrow AgCl(s)+NaNO_3(aq)$

This reaction is a precipitation reaction in which the two aqueous solution silver nitrate and sodium chloride combined to give sodium nitrate solution and silver chloride as a precipitate. In precipitation reaction there is no changes in oxidation state of the element.

Hence, the correct option is, (e) precipitation
