Answer:
12 = Lead
13 = red
Explanation:
12:
Given data:
Mass of metal = 143 g
Volume of metal = 12.6 cm³
Identity of metal = ?
Solution:
To check which metal is this we will calculate the density.
Formula:
d = m/v
d = 143 g/ 12.6 cm³
d = 11.3 g/cm³
The metal is lead.
13:
First of all we will calculate the densities of all liquid. The liquid with the highest density will form the bottom layer.
Blue:
d = m/v
d = 12 g/100 mL
d = 0.12 g/mL
Clear:
d = 10 g/ 100 mL
d = 0.1 g/mL
Red:
d = m/v
d = 15 g/100 mL
d = 0.15 g/mL
Yellow:
d = m/v
d = 13 g/ 100 mL
d = 0.13 g/mL
The density of red liquid is highest from all thus it will form bottom layer.
In the reaction CaI2 (s) + Cl2 (g) → CaCl2 (s) + I2 (s), what phases are the products in after the reaction? Question 1 options: A) CaI2 is a solid, and CaCl2 is in aqueous solution. B) CaCl2 is a liquid, and I2 is a gas. C) Both products are liquids. D) Both products are solids.
Answer:
D) Both products are solids.
Explanation:
In a chemical reaction such as:
CaI2 (s) + Cl2 (g) → CaCl2 (s) + I2 (s)
You can see the phases of the chemicals involved in the reaction inmediately after the chemical formula. Where (s) means solid, (l) liquid and (g) gas
The CaI₂, CaCl₂ and I₂ are solids and Cl₂ a gas.
That means the products are solids and right solution is:
D) Both products are solids.Which of the following is a property that nickel, iron, and cobalt DON'T share?
a) Shiny
b) Poor conductivity of electric current
c) Good conductivity of thermal current
d) None of the above

When _____________ light strikes an object, the _____________ of the object depends on how the object _____________ and/or _______________ the colors of light.
Answer:
When white light strikes an object, the color of the object depends on how the object absorbs and/or reflects the colors of light.
Explanation:
White light is composed of seven distinct colours of light; red, orange, yellow, green, blue, indigo and violet. These colors can be seen when white light is passed through a prism.
The color of an object depends on the colors in the light that falls on it and also on the ability of this object to absorb or reflect this light.
When white light strikes an object, the color of the object depends on how the object absorbs and/or reflect the colors of light.
For example, when white light falls on an object and the object appears green, it means that that object has absorbed all the other colors of white light but reflects green light.
What is a good reducing agent?
A. A substance that is good at oxidizing another atom
B. A substance that is good at reducing another atom
C. A substance that is a good electron acceptor
D. A substance that is easily reduced in a reaction
Answer:
B. A substance that is good at reducing another atom
Explanation:
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized. They have very low ionization energy and easily lose the electron.
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced. It means it gain one more electron.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized. Carbon loses it two more electron and act as reducing agent.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.

What is the relationship between the volume of water and the dripping time?
A. As time increases, the volume of water increases. B. As time increases, the volume of water remains steady.
C. As volume increases, the dripping time decreases.
D. As volume increases, the dripping time remains steady.
Answer:
A
Explanation:
The more time given for the water to drip, the more droplets fall, which increase the volume of the water

Explain why understanding the process of combustion requires using an atomic model of mass and not a continuous one.
Answer:
Combustion is a rapid exothermic chemical reaction between oxygen, O₂, and a substance which is known as the fuel that is initiated by an ignition (heat) source to produce carbon dioxide and water vapor other oxides and combustion products
With the continuous model, which is the model seen with the naked eye, that have uniform parts, the combustion of coal that produces no flammable vapors and hence no flame, the combustion of hydrogen gas which is nearly colorless and the combustion of gasoline that produces a bright flame, burns without flame will be taken as different processes

A zebra grazing in the savannah sees a nearby lion charging to attack and eat the zebra Which of the following is the most likely response of the zebra? Ignore the charging lion O Attack the lion O Run away from the lion O Stand tall and intimidate the lion
Answer:
Run away from the lion
Explanation:
A lion is a top predator of the Savannah forest, meaning that it feeds on a wide range of prey. According to this question, a zebra grazing in the savannah sees a nearby lion charging to attack and eat the zebra. The first instinct of the Zebra is to RUN AWAY FROM THE LION.
The zebra runs because it does not want to get eaten by the fierce predator, owing to the fact that it does not have the physical strength to withstand the lion in a physical combat.
This diagram shows one plate sliding beneath another. what landform is most likely to form at this boundary?
A) Rift Valley
B) Volcanic Islands
C) Fault Line
D) Trench
Answer:
D) Trench
Explanation:
At this boundary, the landform that is most likely to form is trench.
A trench is one of the notable subduction features that occurs as a prominent depression on the earth surface where one plate slides under another.
A trench is very deep and also very narrow. It is a highly conspicuous and prominent feature on the ocean floor. At a subduction zone, the denser oceanic plate slides under that lighter continental plate. Some of the deepest part of the earth can be found along deep ocean trenches. An example is the Mariana trench.Which trend is represented by the graph to the right?
A Atomic Radius
B Reactivity
Clonization Energy
D Electronegativity
what is the reason for the trend in the power of the nucleus going across a period?
Answer:
Please Mark as the Brainliest!!!!! PPPPPPPPPLLLLLLLLLSSSSSS
Explanation:
Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy).
What happens to energy when water changes states of matter from solid to gas?
Answer:
Sublimation is the process from a solid directly into a gas. The particles of a solid absorb enough energy to completely overcome the force of attraction between them. Solid carbon dioxide changes directly to the gaseous state. Therefore the state from soiid and gas can be observed.
