Hey~ :) So, For the first one...  
1. A pH scale<span> measures how much acidic or basic a substance is. </span>The pH scale usually ranges<span> from 0 to 14. .... </span>The pH scale would be, (0 - 14<span>), I think. SO the second one for 1. :) 

2. So, Since a</span><span>n </span>automobile battery<span> can explode or contain and cause a </span>sulfuric acid burn. I'm thinking it would be thee 1st one for the 2nd! :) sulfuric acid<span>

3. </span>Electrochemical and electrolytic reduction cleaning processes, so.... they are the most common techniques utilized to halt, stabilize, and even reverse the oxidation of the metal. So Overall I think this would most-likely Be electrolysis. 

4. Is 1, because, <span>pH of 1 (e) 

5.I am thinking this would Be </span>ion. Because, an ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

HOPE IT HELPS!!!! :)

An organism that obtains organic food molecules by eating other organisms or their by-products
nikitadnepr [17]

Answer:

heterotrophs

Explanation:

According to the parameters established by biology, all living beings that require others to feed themselves are considered heterotrophs, that is, they are not able to produce their food within their organism but rather they must consume elements of nature already constituted as food, already synthesized by other organisms. Among the most prominent heterotrophs, all animals, bacteria and humans stand out.

The term heterotroph comes from the Greek, language in which the prefix hetero means different and trophies means food. In this way, the heterotroph is one that feeds on elements other than one, which takes elements from nature, from the surrounding space to feed. While autotrophic beings have the ability to synthesize inorganic elements such as light, water, carbon dioxide and convert them into food; Heterotrophic beings do not have that capacity, so they must consume plants (in the case that they are herbivores) or animals that have already consumed those plants (that is, in the case that they are carnivorous). In other words, animals and humans always need to feed on other living beings, they could never do so only from inorganic elements such as water.

2. Adelia holds a shiny steel spoon with its back (convex surface) facing her eyes at a distance
My name is Ann [436]

Answer:

(a) The convex mirror image, is always upright at all positions, while images formed by concave mirrors are always inverted when the object distance from the mirror is more than the mirrors focal length.

(b) An upright image is not seen for object at a distance from a concave mirror further than the focal length of the mirror, which is the spoon in the question

Therefore, the location of her eyes of approximately, 30 cm,  from the mirror is more than the mirror's focal length

A plane is flying east when it drops some supplies to a designated target below. The supplies land after falling for 10 seconds.
Diano4ka-milaya [45]

solution:

As Given plane is flying in east direction.

It throws back some supplies to designated target.

Time taken by the supply to reach the target =10 seconds

g = Acceleration due to gravity = - 9.8 m/s²[Taken negative as object is falling Downwards]

As we have to find distance from the ground to plane which is given by d.

d = \frac{1}{2}\times g\times t^2

 = \frac{1}{2}\times (9.8) \times(100) =50\times 9.8=490 meters

Distance from the ground where supplies has to be land  to plane  =  Option B =490 meters

Flura [38]
The presence of helium gas indicates the radioactive sample is most likely decaying by α-decay, or alpha decay. α-decay is the type of radioactive decay in which an atomic nucleus emits α particles. α particles are Helium nuclei. So the correct answer would be α-decay.
