Answer:
The true statements are;
C and D
Explanation:
The tendency of an atom to gain or lose electrons in a chemical reaction are given by its electronegativity and electropositivity respectively
Electronegativity is a measure of an atom's capacity to attract electrons from neighboring particles, with atoms that are more likely to gain an electron, being described as having a higher electronegativity
Electronegativity increases across the period with increasing number of valence electrons, therefore, elements with five, six, or seven electrons, which are located on the far right of the periodic table are said to have higher electronegativity and therefore more likely to gain electrons in a chemical reaction
Electropositivity is the quantification or measure of an element to donate or give electrons and become positively charged ions in a chemical reaction
The fewer the number of valence electrons an element has, the more likely the element will undergo a reaction by donating the valence electrons to a more electronegative atom and become positively charged
Electropositivity decreases across the period and therefore, elements with one, two, or three valence electrons which are located in groups I, II, and III, are more likely to lose electrons in a chemical reaction
In this area the convection is taking place inside the water which is inside the utensils.
<u>Explanation:</u>
- Convection is the type of heat transfer method which is usually taking place through the liquid and gases. In this convection process, the liquid acts as the medium for the heat transfer.
- From the given picture we can see both convection and conduction. The conduction process which occurs in the solid objects. Here the heat is directly given to the pan which is a solid conductor so the pan conducts the heat.
- Inside the pan there happens to be the liquid which favors the convection process and again the eggs are heated by the conduction process as the outer part of the egg is solid.
yes but all of these are correct answers
Answer with Explanation:
We are given that
Force=F=112 N
Distance,
Time, t=3.33 minutes
We have to find the work done by Johnson on the bag and the power generated by Johnson.
Work done, W=
Using the formula
Work done, W=
Power, P=
Using 1 minute=60 s
Hence, the power generated by Johnson=33.3 watt
