Answer:
Yes.
Explanation:
Yes, I think that Barcelona has large temperature changes throughout the year because Barcelona has minimum temperature of 33°F in winter season and maximum temperature of 88°F in summer season. In Barcelona, the summers are short, warm, and humid while on the other hand, the winters in Barcelona are long, cold, and partly cloudy. The temperature typically varies from 40°F to 83°F and is rarely goes below 33°F or above 88°F.

Answer:
No.
Explanation:
The reason comes the <em>Law of Conservation of Mass</em>.
In an ordinary chemical reaction, <em>you cannot create or destroy atoms</em>.
So, you must have as many atoms at the beginning of a reaction (in the reactants) as at the end (in the products)
We use this principle to balance chemical equations.
For example, the equation for the formation of water from hydrogen and oxygen is
2H₂ + O₂ ⟶ 2H₂O
There are four atoms of H and two of O both before and after the reaction.
Chlorine is one of the most effective and economical germ-killers against a wide array of life-threatening infections, viruses and bacteria, such as HIV, salmonella, E. Coli, and campylobacter.
Answer:
65 mg
Explanation:
We are given the dosage per pound but have the weight of the dog in kilograms, thus we should convert the 29.5 kg to punds ( 1 pound = 0.454 kg):
29.5 kg x 1 lb / 0.454 kg = 64.7 lbs
So now can answer our question:
( 1 mg / lb ) x 64.7 lb = 64.7
rounding to 65 mg
