Answer:
0.0003HERE IS YOUR ANSWERdo Plants and animals create energy the same way?
Answer:
Yes
Step By Step Explanation:
Plants extract energy from food molecules the same way animals do — by cellular respiration.
Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called "photosynthesis". ... Plants get their energy in form of starch whereas animals get it in form of glycogen. Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.
Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.

What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

how much heat is released when 32g of water cools from 46°C and freezes
The amount of heat released when 32g of water cools from 46°C and freezes is 6182.4 J
Heat: This is a form of energy that brings about the sensation of warmth. The S.I unit of heat is Joules (J)
⇒ Formula:
Q = cm(t₂-t₁).................. Equation 1⇒ Where:
Q = amount of heat releasedc = specific heat capacity of waterm = mass of watert₁ = Initial temperaturet₂ = Final temperatureFrom the question,
⇒ Given:
m = 32 g = 0.032 kgt₁ = 46 °Ct₂ = 0 °C (Freezing point)c = constant = 4200 J/kg.°C⇒ Substitute these values into equation 1
Q = 0.032(4200)(0-46)Q = -6182.4 JNote: The negative sign tells that heat is released and as such can be ignored.

A student mixes 20.0gof white KCl crystals with distilled water in a beaker. After the mixture was stirred, no crystals are visible and the solution is clear. After several days, all of the water evaporates and white crystals are found in the beaker. Which of following pieces of experimental evidence would best help the student to confirm that a new compound had not been made and that only a physical change occurred?
a- The solution does not change color after stirring.
b- The KCl crystals are no longer visible after mixing with water.
c- There is a temperature change in the solution during the dissolving process.
d- After the water has evaporated, the white crystals in the beaker have a mass of 20.0g
Answer:d
Explanation: over time water evaporates which leaves you with the white crystals mass
A student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.
What is the significance of the physical change?The physical change includes the change in the shape and size of the substances but not the chemical change, as in the case of here the crystal, which is left behind after the evaporation of the solution without any change in the chemical composition.
Hence, a student in a beaker mixes 20.0 g of white KCl crystals with distilled water; no crystals are visible, and the solution is clear, indicating that the physical change has occurred, which is that after the water has evaporated, the white crystals in the beaker have a mass of 20.0 g; that is option d.

Jacinta wrote the following passage about chemical changes.
A chemical change is a change that results in one or more new substances with different properties. When a chemical change occurs, the new substance can give off an odor, such as rotting fruit or cookies baking in the oven. Chemical changes can cause color changes, such as iron rusting and turning a reddish-brown color. When wood is burned or ingredients are mixed for baking a cake, a new substance is made.
Choose the best statement that Jacinta can add to her passage.
Chemical changes, such as rotting fruit and burning wood, are affected by temperature. More heat and energy causes a faster chemical change.
Wood burning and fruit rotting creates new substances through a chemical change that is affected by sound energy.
Rotting fruit and burning wood is a chemical change that occurs because there is a decrease in temperature. Less heat causes a faster chemical change.
When a chemical change occurs, the new substance that is created has properties similar to the original substance.

Explanation:
When [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].
What is a positron emission?In positron emission, also called positive beta decay (β+ decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.
When a proton is converted into a neutron then the positron emission takes place as follows.
[tex]^1_1p\;\rightarrow\;^1_0n\;+\;^0_+1e[/tex]
A positron is represented by the symbol. Therefore, when a positron emission occurs then the resultant nuclei atomic number decreases by a unit mass.
The general equation representing positron emission is as follows.
[tex]^M_ZA\;\rightarrow\;^M_Z_-_1 B\;+\;^0_+1e[/tex]
Hence, fluorine-18 decays by positron emission as follows.
[tex]^1^8_9F\;\rightarrow\;^1^8_8n\;+\;^0_+1e[/tex]
Therefore, when [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?
The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].
The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.
After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.
