Answer:
hope this helps! :)
Explanation:
While humans and many other animals determine sex genetically, many reptiles and some fish use the incubation temperature of the eggs to set the gender of their offspring. This means that changing global temperatures could alter the ratio of sexes produced, making it harder for these animals to find mates
Chemical property is when it's observed during a reaction in which the chemical composition or identity of the substance is changed. physical properties is when properties that do change the chemical nature of matter.
example for this is smell, color, freezing point, etc.
<u>Answer:</u> The conjugate acid of 
is 
<u>Explanation:</u>
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
To form a conjugate acid of , this compound will accept one proton to form
The chemical equation for the formation of conjugate acid follows:
The conjugate acid formed is named as carbonic acid.
Hence, the conjugate acid of is

The refrigerant does all the work. It's a strategy in which a little measure of fluorescent color is infused into and circled through a working framework of an A/C The refrigerant blend will escape and gather at all break destinations.</span>
Answer:
- Option A) <u><em>Mg + Cl₂ → MgCl₂</em></u>
Explanation:
The law of conservation of mass is guaranteed in a chemical equation. Since the mass of the atoms do not change, that means that the number of each kind of atoms in the reactant side is equal to the number of atoms of the same kind in the product side.
The first equation is:
<em><u>A) Mg + Cl₂ → MgCl₂</u></em>
<u />
Number of atoms:
atom Reactant side Product side
Mg 1 1
Cl 2 2
Therefore, the table displays that there are the same number of atoms of each kind on both sides, showing that<em> the total mass during the chemical reaction stays the same.</em>
<u />
<em><u>B) NaOH + MgCl₂ → NaCl + MgOH</u></em>
This equation displays 2 atoms of Cl on the left side and 1 atom of Cl on the right side; thus, it is not showing that the total mass stays the same during the chemical reaction.
<em />
<u><em>C) 2Na + 2H₂O → NaOH + H₂</em></u>
Neither the sodium, nor oxygen, nor hydrogen atoms are balanced. Thus, this does not show that the total mass stays the same.
<u><em /></u>
<u><em>D) H₂O + O₂ → H₂O</em></u>
The reactant side contains 3 oxygen atoms and the product side contains 1 atoms of oxygen; thus, this is not balanced: it does not show that the total mass stays de same during the chemical reaction.
