Answer:
Endothermic
Explanation:
Exo is outside so exothermic would be outside the body
The carbohydrates are break down into glucose. Then glucose combines with oxygen in the cells and provides energy. Hence, digestion is an exothermic process.
What is an exothermic process ?Food digestion produces heat. This happens as a result of the organism releasing heat during meal digestion. A process that releases heat is exothermic.
Heat is released during an exothermic reaction, raising the temperature of the immediate environment. The environment is cooled through an endothermic process that absorbs heat.
Glucose is created by the breakdown of these carbs. In the cells of our body, this glucose interacts with oxygen to produce energy. So, the process of digesting is exothermic.
Chemical processes involved in food digestion disassemble large food molecules into smaller, more manageable "building block" components.
Thus, Human body uses the energy provided from food digestion is exothermic process.

Answer:
All the above
Explanation:
You will analyze four substances in this lab. Based on their chemical formulas and what you already know about covalent and ionic compounds, make a prediction for each compound.Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen
Answer:
Oil: covalent
Cornstarch: Covalent
Sodium chloride: Ionic
Sodium bicarbonate: Ionic
Explanation:
Covalent compounds are formed by sharing of electrons between non metals whereas ionic compounds are formed by transfer of electrons from metals to non metals.
1. Oil, which is built from the nonmetals hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
2. Cornstarch, a carbohydrate consisting of hydrogen, carbon, and oxygen: forms a covalent compound by sharing of electrons between non metals hydrogen, carbon, and oxygen. Covalent compounds are insoluble in water.
3. Sodium chloride (table salt), whose formula is NaCl is formed by transfer of electrons from sodium to chlorine.Ionic compounds are soluble in water.

1. Decide which of the following is the best observation.
The dog ate the bone hiding.
The dog ate the bone hiding under the tree.
The dog ate the bone hiding under the shady tree.
The dog ate the bone.
Answer:
The dog ate the bone hiding under the shady tree.
Explanation:
The best observation is that the dog ate the bone hiding under the shady tree. This is because it provides the most graphic details about the position and activities of the dog.
With this choice, we can properly picture the dog and the relationship it has with the tree. The more information we know about a subject of investigation, the better an observation it affords. Such a well informed observation will make analysis much better.Answer:
The dog ate the bone hiding under the shady tree.

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.
Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
[tex]l=0,1,2[/tex]
Magnetic quantum number :
The magnetic quantum number is
[tex]m=-2,-1,0,1,2[/tex]
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.

Compare and Contrast Heating and
Cooling curves.
Answer: Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.

Which element has 5 protons 5 neutrons and 5 electrons
Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.
What are subatomic particles?Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.
The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.

Explain what happens if you change the number of protons in an element?
Plzzz helpppp!!!
Answer:
When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.
