Answer: AURORA'S 5

Explanation:

First of all, it is important to understand what solar flare is, before we can talk about the impact it causes. I will like to describe solar flare as a massive explosion on the Sun that results when energy stored in magnetic fields are released suddenly. This is normally seen as an intense variation in brightness on the Sun and this radiation are dangerous to living organisms. A solar flare when released is deposited in a very short timeframe and this flare contains a very large amount of photon energy as well as particle energy. Scientists or preferably Astronomers classifies flares in five categories; A, B, C, M, and X. This ranking is classified according to its strength from class A being the weakest to class X being the strongest and deadliest of the five.

EFFECTS:

When this radiation reaches the earth, a particularly strong coronal mass ejection (CME) can disrupt the power grids, from blowing out electric transformers and power stations to induction of high currents in power lines, which would then result to electricity shortages, power outages and that alone has its own effect on industries, and the general wellbeing of the human race. The M class of this flare category when released can generate brief radio blackouts at the polar regions of the earth and this changes in the atmosphere can destroy the precision of Global Positioning System (GPS) measurements, and can also cause radiation storms which directly affects orbiting astronauts. I won’t fail to mention how badly affected our internet services would turn out, and that battery-operated equipment would go faulty.

A 50-mL beaker only has a scale that measures 10, 20, 30, and 40 mL. What is the uncertainty associated with the 50 mL beaker.
Juliette [100K]
If the uncertainty of a certain measurement instrument is not given, then it is assumed to be equal to half of the least count of that instrument. In this case, the least count is 10 ml, so half of this is 5 ml. Therefore, the graduated cylinder has an uncertainty of +/- 5 ml

Classify each of the observed changes according to whether or not they are likely to represent evidence that a chemical reaction
Mama L [17]

Answer:

a solution color becoming less intense  due to dilution- is not an evidence of a chemical reaction

bubbles (gas formation) - evidence of a chemical reaction

explosion or fire - evidence of a chemical reaction

changes in color- evidence of a chemical reaction

precipitation- evidence of a chemical reaction

changes in temperature - evidence of a chemical reaction

a solid liquifying - is not an evidence of a chemical reaction

solution colors mixing - is not an evidence of a chemical reaction

Explanation:

A chemical change is not easily reversible and yields new substances. It is often accompanied by a loss or gain of heat.

In the answer section, i have shown some evidences that lead us to conclude that a chemical reaction has taken place. The occurrence of a chemical change often goes with the formation of new substances as earlier stated and any of these signs may accompany the process.

For instance, when a metal is dropped in dilute acid solution, bubble of hydrogen gas indicates that a chemical reaction has taken place.

How many O2 molecules can be made with the oxygen from 492 g of sodium phosphate?
serg [7]
<span>To answer this question, you need to change the sodium phosphate unit into mol and doing the reaction. Sodium phosphate or Na3PO4  molecular weight is 163.94 or 164 rounded up. Then the amount should be: 492g/ (164g/mol)= 3 mol

For every 1 mol of </span>Na3PO4  there are 4 mol of oxygen element. To made 1 mol of O2 molecule, you will need 2 mol oxygen element. Then the amount of oxygen should be: 4/2 * 3 mol= 6 mol * 6.02 * 10^23= 36.12 * 10*23= 3.61 * 10^24

A Nuclear reactor produces product 20kg of uranium-235.if the half life is about 70years , how long will it take to decay to 0.1
VikaD [51]

Answer:

t=(70)ln(19.9/20)/-ln2

70 is the years. 19.9 kg is what is left after 0.1kg decay. 20kg is your initial amount.

t=0.506 years with a decay constant of 0.0099021/year
