221 A grocery shop has different types of fruit: one box contains 10 mangos, another
contains 7 avocados and the third box contains 5 lemons.
The same shop has 20% organic food. 50% inorganic food, and 30% of the things they sell
are juices.
3 marks)
A) Represent the types of fruit in bar graph.
B) Represent the sales in pie graph.
Answers
Answer:
A) Please see the required bar graph attached
B) Please see the required pie graph attached
Explanation:
The given data are;
The number of each fruit in each box are;
First box contains 10 mangoes
Second box contains 7 avocados
Third box contains 5 lemons
The percentage of the things they sell are;
Organic food = 20%
Inorganic food = 50%
Juices = 30%
A) The bar graph is plotted with Microsoft Excel
The height of each column is equivalent to the number of fruit in the box
Each column represents a box of fruit
B) The pie graph (chart) is generated with Microsoft Excel
The steps to draw the pie chare are;
1) Draw a circle
2) Partition the circle into segments proportional to each percentage from the center of the circle as follows;
The sum of angles at the center of the circle = 360°
The angle of the segment that will represent the 20% organic food in the pie chart = 20/100 × 360° = 72°
Therefore, the segment representing organic food will have an angle of 72° at the center of the circle
Similarly, the segment representing inorganic food will have an angle of 50/100 × 360° = 180° at the center of the circle
The segment representing juices will have an angle of 30/100 × 360° = 108° at the center of the circle.

How do tectonic plates move at convergent subduction boundaries? Insert a drawing with the arrows that show the movement
Answers
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lithium?
Answers
Explanation:
Lithium is an electropositive element that readily loses electrons.
Oxygen is electronegative and it will readily accept electrons.
Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.
2atoms of Li lose two electrons:
Li → Li²⁺ + e⁻
Lithium isoelectronic with helium
For oxygen;
O + 2e⁻ → O²⁻
Oxygen is isoelectronic with Neon
Two ions of the lithium combines with the oxygen to form the bond;
4Li + O₂ → 2Li₂O
The electrostatic attraction between the two ions forms the ionic bond

1. What is volume displacement? Why would you use this method?
2. What is density? What happens to things that are denser? What happens if they are less dense?
Answers
Answer:
1. The volume of displaced fluid is equivalent to the volume of an object fully immersed in a fluid or to that fraction of the volume below the surface of an object partially submerged in a liquid. The weight of the displaced portion of the fluid is equivalent to the magnitude of the buoyant force.
Why would you use this method?
So it can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.
2. Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
What happens to things that are denser?
Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.
What happens if they are less dense?
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?
Answers
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2

with calculations
Answers
Answer:
The answer is 6.941 but I dont really have the explanation
Explanation:
The atomic mass of lithium will be 6.9458 amu.
What is Atomic Mass ?
The mass of an atom of a chemical element expressed in atomic mass units.
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Calculation :
Consider 10000 atoms of Li ;
742 of them would have mass 6.02.9258 of them would have mass 7.02.
Hence,
The total mass of these 10000 Li atoms would be ;
(742 × 6.02) + (9258 × 7.02) = 69458
∴ 1 Li atom on average would have mass = 69458 / 10000 = 6.9458 amu
Therefore, The atomic mass of lithium will be 6.9458 amu.

Answer:
The speed of light becomes slower in denser medium which is water in this case.
Explanation:
We know the lens law of Refraction which states
[tex]\frac{Sin(i)}{Sin(r)} =[/tex] Refractive index of second medium /Refractive index of the first medium
= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)
When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.
When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.

If 0.484J of heat is added to 0.1372g of water, how much will the temperature increase?
0.263 °C
0.927 °c
0.843 °C
0.460 °C
Answers
Answer:
ΔT = 0.843 °C
Explanation:
Given data:
Heat added = 0.484 J
Mass of water = 0.1372 g
Temperature increase = ΔT = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity of water is 4.184 j/g.°C
Now we will put the values in formula.
0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT
0.484 j = 0.574j/°C× ΔT
ΔT = 0.484 j / 0.574j/°C
ΔT = 0.843 °C
