I need help on both pls. I need correct answers

Answers

Answer 1

Answer: 1. When a lion eats a zebra and then uses the energy from the zebra to run, the lion's body converts **chemical energy -> mechanical energy**. The energy stored in the chemical bonds of the zebra's tissues (from its food) is converted into mechanical energy as the lion's muscles contract and allow it to move.

2. In gym class, as you run a mile, your body undergoes the following energy transformation: **chemical to mechanical and thermal**. The chemical energy stored in the food you've consumed is converted into mechanical energy as your muscles propel you forward during the run. Some of this energy is also transformed into thermal energy due to the heat generated by your muscles working.

I think of myself of resilient because _________________. Naming the space craft RESILIENCE is smart because the astronauts will know they are safe when they launch.

Explanation:

The elements in Group 2 have similar chemical properties because each atom of these elements has the same(a) atomic number
(b) mass number
(c) number of electron shells
(d) number of valence electrons

Answers

Answer;

- (d) number of valence electrons

The elements in Group 2 have similar chemical properties because each atom of these elements has the same number of valence electrons.

Explanation;

-Group 2 elements are also called alkaline earth metals, such as calcium, magnesium, strontium, barium , etc.

-These metals have a valency of two, which means they have two electrons in the outermost energy shell. Therefore; they react by loosing two electrons to form a stable configuration or an octet configuration. They are highly metallic and are good conductors of electricity.

The elements in Group 2 have similar chemical properties 'cause they have the same no. of electrons.
