Answer:

The contracting nebula flattens into a disk with a bulge at the center.

Explanation:

Sun was formed in solar nebula about 4.5 billion years ago. Solar nebula is a molecular cloud of dust and gases which slowly spun and collapsed due to condensation of gases. The cloud started spinning faster and collapsed. Thereafter, the contracted nebula flattened into a disk and bulge at the center was formed. The temperature and pressure rose till the nuclear fusion reaction started releasing huge amount of energy. The sun was born. The rest of the matter accreted to form planets.

malfutka [58]

Calculate the ratio by using Henderson-Hasselbalch equation:

pH = pKa + log [neutral form] / Protonated form

3.05 = 2.21 + log [neutral form] / [Protonated form]

3.05 - 2.21 = log [neutral form] / [Protonated form]

0.84 = log [neutral form] / [Protonated form]

[neutral form] / [protonated form] = anti log 0.84 = 6.91

Given the balanced equation representing a reaction:

Vladimir79 [104]

Answer:

Option A. Addition

Explanation:

Unsaturated compounds under goes addition reaction to produce saturated compounds..

In the equation given above i.e

H2C=CH2 + F–F —> FCH2CH2F

we can see that the double in H2C=CH2 disappear by the reaction of F–F to produce FCH2CH2F which has no double. This simply indicates that the F–F was added to H2C=CH2. Hence, the reaction is called addition reaction.

The speed of light is 1.86×10^5 miles per second.how many meters will light travel in 1.0 seconds

evablogger [386]

Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). ... The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.
