Chemistry
1 answer:
andreev551 [17]3 years ago
3 0

Answer:

B. aq if the reaction is inorganic (double or single displacement), neutralization, etc.

Explanation:

Hello there!

In this case, unfortunately we are not given the undergoing chemical reaction; however, in the most of the double displacement, neutralization, precipitation and in general, inorganic reactions, the hydrochloric acid must be B. aq as it must be dissolved in water as the reaction media. On the other hand, in some organic reactions, it can be either aqueous or gaseous, the latter, specially as a product. For that reason, you will need to make sure whether your reaction is organic or inorganic to correctly figure out the phase label.

Best regards!

The chemical equation below shows the decomposition of nitrogen triiodide (NI3) into nitrogen (N2) and iodine (I2).
Travka [436]
2 NI₃= N₂ + 3 I₂

2 x 394.71 g --------------- 3 x 253.80 g
3.58 g ---------------------- ( mass  of I₂ )

3.58 x 3 x 253.80 / 2 x 394.71 =

2725.812 / 789.42 => 3.4529 g of I₂

1 mole I₂ --------------- 253.80 g
?? ----------------------- 3.4529 g

3.4529 x 1 / 253.80 => 0.0136 moles of I₂

Answer C

Dna is approximately 2.5 nm in length. of an average man is 5 ft 10 in. tall, how many dna molecules could be stacked to extend
Angelina_Jolie [31]
To determine the number of dna molecules that can be stacked as requested in this item, we convert the given measurements in a single unit. For simplicity, we convert all the lengths to meters.

Length of DNA molecule = (2.5 nm)(1 x 10^-9 m/1 nm) = 2.5 x 10^-9 nm

Height of a person = (5 ft 10 in)(12 inches/ 1ft)(2.54 cm/1 in)(1 x 10^-2 m/ 1 cm)
               = 1.778 m

Then, divide the height of the person by the length of a single DNA molecule.

       n = 1.778 m / (2.5 x 10^-9)
       n = 7.112 x 10^8

Hence, the number of DNA would be 7.112 x 10^9.
