Answer:
0.1 dm³.
Explanation:
To obtain the value of 100 cm³ in dm³, do the following:
Recall:
1 cm³ = 0.001 dm³
Therefore,
100 cm³ = 100 cm³ × 0.001 dm³ / 1 cm³
100 cm³ = 0.1 dm³
Thus, 100 cm³ is equivalent to 0.1 dm³.
Answer:
Question 7 the answer is B
Explanation:
In every nuclear reaction there is always formation of products either by nuclei bombardment or by the elements breaking into two elements of the same mass
Question 8
The answer is A
Nuclear reactions release a huge amount of energy than chemical reactions
Atoms of the same elements differing in the number of neutrons in their nuclei are known as isotopes. Thus, isotopes of an element have the same atomic number but different atomic mass number. Isotopes of an element have similar chemical properties but different physical properties.
