Answer:
Option D. ZnCl₂ and H₂
Explanation:
From the question given above, the following equation was obtained:
2HCl + Zn —> ZnCl₂ + H₂
Products =?
In a chemical equation, reactants are located on the left side while products are located on the right side i.e
Reactants —> Products
Now, considering the equation from the question i.e
2HCl + Zn —> ZnCl₂ + H₂
The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.
Thus, option D gives the correct answer to the question.
The moon phases maybe? Can I see the passage possibly?
To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,
H = mcpdT
where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,
H = (30.0 g)(0.90 J/gC)(75 - 25)
H = 1350 J
Thus, there is a need for 1350 J of heat for the process.
The rounded three digits for the given number is 2.46
<u>Explanation:</u>
Significant figures are the number of digits in a value which contributes to the degree of accuracy of the value while measuring
<u>Rules:</u>
- Digits which are not zero are always essential.
- Any zeros between two major digits are important.
- Only a final zero or trailing zeros are important in the decimal section
<u>Solution:</u>
- Given number- 2.45986
- Decimals- 5 digits
- Scientific Notation
-2.45986 × 10^0
- Applying the rules until rounding the 3 digits we get,
- The rounded three digits for the given number is 2.46
