Answer:
because the particles in solids are more close together and strong so they would support it better than fluid because fluid particles are spread out
Explanation:
Have A Wonderful Day !!
Due to properties of solid substances, they support objects easier than liquid.
Solids can support objects easier than fluids because in solid, particles are present on fix place as compared to liquid which is not fix and can move from one place to another. In Solid substances, particles are fix so they provides better support to the objects which are placed on them.
While on the other hand, in liquid substances particles are mobile so they are not considered better supporter for objects so we can conclude that due to properties of solid substances, they support objects easier than liquid.

A potted plant is placed under a grow lamp, which provides 4,200 J of energy to the plant and the soil over the course of an hour. The specific heat capacity of the soil is about 0.84 J/g° C and there are about 2,400 g of soil. How much does the temperature of the soil increase?
Answer:
Temperature increase = ΔT = 2.08 °C
Explanation:
Given data:
Energy absorbed by plant = 4200 J
Specific heat capacity of soil = 0.84 J/g°C
Mass of soil = 2400 g
How much temperature increase = ?
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
by putting values,
4200 J = 2400 g ×0.84 J/g°C × ΔT
4200 J = 2016 J/°C × ΔT
ΔT = 4200 J / 2016 J/°C
ΔT = 2.08 °C

Part 2
Observe the image of hydrogen chloride. List the properties you see.
Answer:
Observable properties of sodium from the image:
1. It's slivery-white solid
2. It's shiny and bright
3. Looks soft
4. Looks waxy
Observable properties of hydrogen chloride from the image:
1. It is a colorless liquid
2. It is transparent
Explanation:
Sodium is known to be a metal that is silvery-white and waxy in appearance. The metal is bright and shiny especially when it is cut. It can be cut with a knife due to it soft nature. It is reactive and has low melting point. It actually reacts with water to form sodium hydroxide.
Hydrogen chloride (known to be hydrochloric acid) is a transparent and colorless substance. It is used in manufacturing plastics, textile, fertilizers, etc. The concentrated hydrogen chloride is very corrosive.
The above are what I can see from the image.

Think and discuss: Why is there an attraction between the two ions in this chemical bond?
Answer:
These ions are attracted to each other due to its opposite charges. This force of attraction is called an ionic bond because it is formed by the attraction of two atoms with opposite charges.
Explanation:
LOL im answering this question for a gizmo assingment rn
There is an attraction between two ions in a bond because they are composed of opposite charges.
In science, we know that opposite charges attract while like charges repel according to the first law of electrostatics. Ionic bonds are composed of metal and non metal ions. The metal ions are positively charged while the nonmetal ions are negatively charged.
These oppositely charged ion pair constitute the ionic bond therefore, there an attraction between the two ions in this chemical bond because they are unlike charges.

An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2.0 mL. The height of the water rose to 7.0 mL. If the mass of the stone was 25 g, what was its density?
Answer:
Density = 5 g/mL
Explanation:
Given data:
Volume of water = 2.0 mL
Volume of water + stone = 7.0 mL
Mass of stone = 25 g
Density of stone = ?
Solution:
Volume of stone = (volume of water + stone) - volume of water
Volume of stone = 7.0 mL - 2.0 mL
Volume of stone = 5.0 mL
Density of stone = mass/ volume
Density = 25 g/ 5.0 mL
Density = 5 g/mL

What would Thomson's model and Rutherford's model of the atom have in common?
Answer:
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
