the physical and chemical properties of the products Are different from the reactants. This causes the changes to be seen, physical changes and chemical.
Answer:
Yes, it is still sugar.
Explanation:
Melting is a physical change, in which a substance passes from a state of aggregation to other. During physical changes, the nature or identity of the subtance does not change. So, when sugar melts it changes only its state of aggregation: it passes from the solid state to the liquid state, but it is still the same substance: sugar.
Answer:
A. Clear and Sunny
Explanation:
The answer would be A. Clear and Sunny. A high pressure system occurs where the air mass above the Earth is denser than in surrounding areas, and therefore exerts a higher force or pressure. They usually happen with li9ght winds. Using process of elimination, it could not be D. Warm and Stormy, C. Cloudy and Rainy, or B. Cold and Stormy because all have wet climates.
2NOCl ⇄ 2NO + Cl₂
K = [NO]²[Cl₂]/[NOCl]
K = [0,0012]²[0,0022]/[0,014]²
K = 0,000000003/0,000196
K = 0,000016163
Q, R, S, P is the order of apparent magnitude of the stars, starting from the least to the greatest.
Answer: Q, R, S, P
<u>Explanation:</u>
The apparent magnitudes of the star is the brightness calculated by an observer at a particular distance from the Earth. The smaller the distance between the star and the Earth, the greater the apparent brightness.
So , from the given distance (in light years), Q,R,S,P is the answer (least to the greatest apparent magnitude) (distance is greatest to least).
