Answer:

The correct answer is "Its rate will be slower than when it is closer to the Sun".

Explanation:

The Earth passes through its furthest point from the Sun in its orbit, which is known as aphelion. According to Kepler's second law, the greater the distance, the lower the orbital velocity of translation. This happens because in its displacement around the Sun, the Earth does not have a perfect circular trajectory but an elliptical one. Kepler stated that the line connecting the planets and the Sun covers the same area in the same amount of time, so that when the planets are close to the Sun in its orbit, they move faster than when they are farther away.

Have a nice day!

If the earth's orbit is far from the sun, then, its rate will be slower than when it is closer to the Sun. When gravitational field lines get closer together, the magnetic force is strong. We know that the heavier the body is, the stronger its gravitational pull.<span>

Acid indigestion is sometimes neutralized with an antacid such as magnesium hydroxide (Mg(OH)2). What products will be released

Lunna [17]

Answer: d) $MgCl_2$ and $H_2O$ 

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water. The $H^+$ ions from water reacts with $OH^-$ ions from base to give water.

$2HCl+Mg(OH)_2\rightarrow MgCl_2+2H_2O$

Thus products that will be released when the antacid is mixed with the hydrochloric acid in the stomach are $MgCl_2$ and $H_2O$

What are the reactants in a neutralization reaction? two elements an acid and a base an element and a compound a salt and water

Vitek1552 [10]

ok thank you for elaborating and you are correct in a neutralization reaction the reactants are the acid and base. the salt and water would be the product and the two elements could be anything meaning that it is most likely a mixture

Hope this helps

What is a controlled factor in an experiment?

Romashka-Z-Leto [24]

Sorry this will probably be pretty long.

So think of the "control" as being something you yourself add to increase or decrease the effects in an experiment.
I'll give you an example so it is not as confusing.
Say you have decided to make an experiment on plants. Which plant can grow the fastest on which type of liquid? What is being added to this experiment? The liquid! Or all of the liquids you used. Like if you used Coke, Lime Gatorade, Orange Gatorade, and Water. Each drink will EFFECT each plant differently.
Hope I was of any hope?
