in a petri dish, a certain type of bacterium doubles in number every 30 minutes. there were originally 16, or 2^4, bacteria in t

he dish. after 150 minutes, the number of bacteria has doubled 7 times, multiplying by 2^7. Now the population of bacteria is 2^4 • 2^7. Expressed as a power, how many bacteria are in the petri dish after 150 minutes? A. 2^28 B. 2^11 C.4^11 D.2^7

The concentration of HCl can be determined by titration with a primary standard such as Na2CO3 (sodium carbonate). The titration
Masteriza [31]

Answer:

The concentration of HCl is 0.275 M

Explanation:

<u>Step 1:</u> Data given

Mass of Na2CO3 = 0.521 grams

Molar mass of Na2CO3 = 105.99 g/mol

Volume of HCl = 35.7 mL

<u>Step 2: </u>The balanced equation:

2HCl + Na2CO3 → 2NaCl + CO2 + H2O

CO3(2-) + 2H+ ---> H2O + CO2

<u>Step 3</u>: Calculate moles of Na2CO3

Moles Na2CO3 = mass Na2CO3 / Molar mass Na2CO3

Moles Na2CO3 = 0.521 grams / 105.99 g/mol

Moles Na2CO3 = 0.0049 moles

<u>Step 4:</u> Calculate moles of HCl

For 1 mol of Na2CO3 consumed, we need 2 moles of HCl

moles of HCL = 2 * 0.0049 = 0.0098 moles HCl

<u>Step 5:</u> Calculate molarity of HCl

Molarity = number of moles of HCl / Volume (liters)

Molarity = 0.0098 moles / 0.0357 L

Molarity = 0.275 M

The concentration of HCl is 0.275 M

Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?
Phoenix [80]

Answer: Option (B) is the correct answer.

Explanation:

It is known that for writing a chemical reaction equation, reactants are written on left hand side whereas products are written on right hand side.

And in between reactants and products a forward arrow is placed pointing towards the products.

Therefore, the reaction for carbon burns in the presence of oxygen to give carbon dioxide will be written as follows.

          Carbon + Oxygen \rightarrow Carbon dioxide

Here, carbon and oxygen atoms are the reactants whereas carbon dioxide is the product.
