valentina_108 [34]

Answer:

On the farm there are 70 chickens.

Explanation:

We can directly <u>work out the number of ducks from the given number of pigs</u>, with the <em>ratio of ducks to pigs</em>:

  • 36 pigs * \frac{5Ducks}{9Pigs} = 20 ducks

Then we<u> work out the number of chickens</u>, using the ration of chickens to ducks:

  • 20 ducks * \frac{7Chickens}{2Ducks} = 70 chickens

If on the farm there are 36 pigs, there are 70 chickens as well.

Answer:

 The correct answer is option A, that is, HCl.  

An acid refers to an ion or molecule possessing the tendency of donating a hydrogen ion or a proton, or alternatively, exhibiting a tendency of producing a covalent bond with a pair of electrons. The aqueous Arrhenius acids exhibit characteristic features that offer a practical illustration of an acid.  

The acids can turn blue litmus paper red, can form aqueous solutions with a sour taste, and reacts with bases and some kind of metals to produce salts. One of the general aqueous acids is HCl (hydrochloric acid) that is found in the stomach and stimulates digestive enzymes.

given that 32.0g sulphur contains 6.02×10^23 sulphur atoms,how many atoms are there in 2.70g of aluminum​
dangina [55]

Answer:

6.022 × 10²² atoms

Explanation:

Generally 1 mol of any element contains 6.02×10^23  atoms. The number 6.022 × 10²³ is known as Avogadro's number.

Mass of Aluminium = 2.70g

Molar mass = 27g/mol

Number of moles = Mass / Molar mass = 2.70 / 27 = 0.1 mol

1 mol =  6.022 × 10²³

0.1 mol = x

x = 6.022 × 10²³ * 0.1 = 6.022 × 10²² atoms
