1. The correct statement that describes a Redox reaction is ( D ) ; A chemical reaction in which electrons are transferred between reactants.
2. The chemical formula that shows the correct subscripts is ( D ) BeF₂
3. The type of reaction that is shown is ; ( C ) decomposition reaction
A Redox reaction ( oxidation-reduction reaction ) involves the exchange/transfer electrons between reactants and the change in the oxidation number of the molecules involved in the reaction changes when an electron is either gained or lost.
Given that the Be has four ( 4 ) electrons and Fluorine has nine ( 9 ) electrons when they combine Fluorine will be left with an excess of electrons therefore the correct chemical formula will be BeF₂
The breaking up of an element into its smaller parts in a chemical reaction is known as a decomposition reaction.
Based on the information given, there's something wrong with the response of the friend towards the hospitality shown to him.
<h2>
What is hospitality?</h2>
From the question, it was stated that a friend came visiting and the friend's mum was hospitable to him and cooked for him. He wanted to pay for the food when he gets as he was going and this is wrong.
It's problematic that the friend is asking for payment for her loving presence. This illustrates that he hasn't been shown kindness or has probably been paying for things and doesn't have loving people around him.
In conclusion, it's awkward because one isn't meant to pay for a hospitable act.

Answer:
Tools used in Lower Paleolithic era were mainly cleavers, choppers, and hand axes. These tools were mainly used for cutting, digging, and skinning the prey. These tools were found from Belan Valley of Mirzapur (U.P.), Didwana in Rajasthan, Narmada Valley, and from Bhimbetka (near Bhopal, M.P.).
Answer: Hypothesis
