The volume of Carbon dioxide at STP = 209.22 L
Further explanationGiven
411g of Carbon dioxide gas
Required
The volume of Carbon dioxide
Solution
mol of Carbon dioxide :
= mass : MW CO₂
= 411 g : 44 g/mol
= 9.34
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
So for 9.34 mol :
= 9.34 x 22.4 L
= 209.22 L

An atom of carbon (C) forms covalent bonds with two atoms of oxygen (O) to form carbon dioxide. How are the valence electrons of these atoms rearranged to form the bonds?
Electrons are transferred from the carbon atom to the oxygen atoms.
Electrons are transferred from the oxygen atoms to the carbon atoms.
Many valence electrons are shared between the atoms.
A few valence electrons are shared between the atoms.
Answer:
Many valence electrons are shared between the atoms.
Explanation:
For the atoms to form a covalent bond, a many of the valence electrons are shared between the atoms.
When a covalent bond is to be formed, the valence electrons which are the outermost electrons are shared between the atoms that are combining.
Carbon is made up of 4 valence electrons. Oxygen is made up of 6 valence electronsFor both atoms to be isoelectronic with the noble gases, carbon shares all of its 4 electrons with oxygen. Oxygen bonds shares 4 electrons using two of its atom with the carbon.Answer:

In two or more complete sentences explain how to balance the chemical equation,
CH2 + O2 CO2 + H2O and include all steps.
Remember:
to balance equations in chemistry, you have to count the amount of atoms there are in a chemical eg:
the number of atoms in H20 are:
2 atoms of hydrogen
1 atom of oxygen (when there are no numbers by the letter it means that theres only 1 atom of it!)
The number next to a letter means the number of atoms thta it is made up of and atoms are the things it is made up of eg chocolate the ingredients are cocoa, milk and sugar ect so just like that CO2, H20 an ALL types of chemicals are made up of atoms. BUT WE WANT TO KNOW HOW MANY ATOMS- so u need to list these for all the 4 chemicals in the equation.
Im telling u this so that u can list out all of the atoms in each chemical (I will do the first two)
CH2=
1 atom of Carbon
2 atoms of hydrogen
O2=
2 atoms of oxygen
once u have listed out all the atoms from EACH of the chemicals in ur question (CH2, 02, CO2 and H20) categorise them like this
CH2
Carbon=........ Atoms
Hydrogen= .......Atoms
(Make sure the table is like vertical like lemme show u as an example. ATTACHED IS AN EXAMPLE OF WHAT UR WORK SHOULD BE SET OUT AS)
When you see the addition sign it means that elements like oxygen and hydrogen etc..basically add them up like CO2 + H20 theres oxygen in both so add up the atoms of oxygen FOR JUST CO2 AND H20 like if there was one atom of oxygen in CO2 and 2 in h20 add them up and it makes three (1+2=3). 1 oygen atom from CO2 plus 2 oxygen atoms in H20 that makes 3 atoms for both the chemiclas together (THIS WAS JUST AN EXMAPLE THERE ARENT ACTUALLY 2 ATOMS IN H20 OR 1 ATOM IN C02)
Look at the similarities OF ATOM NUMBERS like if CH2 has one atom of Carbon, CO2 ALSO has one atom of carbon which is fine BUT when it comes to differences u need to cross those out and PUT THAT NUMBER on both sides like if O2 has 2 atoms of oxygen and h20 has 1 that means that they need to be balanced like they either both need to be 1 atom or 2 atoms so for that u need to look attachment sorry u just need to cross them out and make them the same
make sure to write about what atoms are, to list out atoms for each chemical, compare the chemicals in both word chemicals and make them even!
Explanation:
Hydrogen is placed separately from the other elements in the periodic table because it
A. Is a gas
B. Has atomic number 1
C. Has many unique properties
D. Does not exist as a free element in nature
Hydrogen is the chemical element that is placed separately from the other elements because it has atomic number 1.
What is hydrogen?It is the simplest chemical element (consisting of only one proton and one electron) with atomic number 1.
It is the lightest of the elements and the most abundant in the universe and in the earth's crust, in the atmosphere, hydrogen is found as a colorless, odorless and flammable gas, in its molecular form H2.
Therefore, we can conclude that Hydrogen is the chemical element that is placed separately from the other elements because it has atomic number 1.

A scientist was working in a nuclear reactor facility and was exposed to radioactive particles. Although the scientist was wearing only basic clothing as protection, she exhibited no symptoms of radiation poisoning. What type of radiation was the scientist most likely exposed to?
Group of answer choices
A. Beta
B. Gamma
C. Alpha
D. None of the above
Answer:
C. Alpha
Explanation:
In a nuclear reactor facility, radioactive decay takes place, which is any several processes by which unstable nuclei emit subatomic particles and ionizing radiation and disintegrate into one or more smaller nuclei. A scientist working under this condition is likely to be exposed to alpha particles because it contains a minimal absorption range and they are the least dangerous regarding external exposure.
2.At 35°C, a small sample of methane gas (CH4) has a volume of 1.5 liters. The temperature of the methane gas is slowly cooled to 17°C. What is the new volume of the methane sample?
Answer:
V₂ = 1.41 L
Explanation:
Given data:
Initial temperature = 35°C (35 +273.15 K = 308.15 K)
Initial volume = 1.5 L
Final temperature = 17°C (17+273.15 K = 290.15 K)
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 1.5 L × 290.15 K / 308.15 k
V₂ = 435.23 L.K / 308.15 k
V₂ = 1.41 L

Which statement would be true if glucagon secretion were permanently inhibited, resulting in negative feedback?
Blood glucose levels would decrease.
Glycogen formation would be inhibited.
Insulin production would decrease.
The synthesis of fat would decrease.
Answer:
Insulin production would decrease.
Explanation:
Insulin and Glucagon work together to balance the sugar levels in the human blood stream. They work together in a negative feedback loop. Glucagon stimulates the liver to release glucose into the bloodstream in a process known as glycogenolysis. Insulin on the other hand is a sugar-lowering hormone.
Therefore, if glucagon secretion were permanently inhibited, insulin production would decrease as there would not be excess blood sugar to be reduced.
Answer:
Insulin production would decrease.

24. Two boys were each pushing a box to the right, one boy applied a force of 3N and
the other boy applied a force of 5N. Another boy was pushing the box to the left
with a force of 8N. What was the net force of the box?
Answer:
Explanation:
Two boys were each pushing a box to the right, one boy applied a force of 3N and the other boy applied a force of 5N.
Total force applied to the left = 3 + 5 = 8 N . The forces are added up because they act in the same direction .
Another boy was pushing the box to the left with a force of 8N.
8 N force acts opposite to the total force of 8 N exerted by two earlier boys so
net force = 8N - 8N = 0 .
Net force on the box = 0 .

Among the following the molecule which does NOT contain a covalent bond is CaO Hence correct option is (A).
What is Covalent bond ?Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms.
As in CaO , Ca is considered as Metal which has Electron donor nature hence it will donate electron to Oxygen.
Whereas Oxygen Considered as Non metal as it gains electron. which has electron gainer nature.
Ca donates electron and Oxygen gains electron. Thus, the bond formed between both will be the Ionic bond which is formed by the transfer of Electron.
Therefore, Among the following the molecule which does NOT contain a covalent bond is CaO Hence correct option is (A).
