In two or more complete sentences explain how to balance the chemical equation,
CH2 + O2 CO2 + H2O and include all steps.
Answers
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!

Answer:
A compound is a substance in which the atoms of two or more elements are chemically combined in a fixed proportion.
Explanation:
The correct answer is that a compound is a substance in which the atoms of two or more elements are chemically combined in a fixed proportion.
A compound is a substance composed of two or more kinds of atoms joined together in a definite grouping.
The properties of a compound are distinct and different from those of the individual elements that are combined in its make - up.
There are several millions of compounds known.
An element is a distinct substance that cannot be split-up into simpler substances. They are made up of only one kind of atom.

What is the total number of moles of CO used to produce 112 grams of iron?
Answers
Answer:
3 moles of CO are needed
Explanation:
Given data:
Number of moles of CO used = ?
Mass of Fe produced = 112 g
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of Fe:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 55.85 g/mol
Number of moles = 2.00 mol
Now we will compare the moles of iron and CO.
Fe : CO
2 : 3
Thus, 3 moles of CO are needed.

C8 H18 + O2 CO2 + H2O
Answers
Answer:
2C8H18 + 25O2 → 16CO2 + 18H2O
Explanation:
Reactant
There are 16 Carbon 2x8 = 16
36 Hydrogen 2x18 = 36
And 50 oxygen 25x2= 50
Product
There are 16 carbon
And 50 oxygen atoms
From the CO2 the amount of oxygen atoms are 32 (16x2=32)
And from the H20 the amount of oxygen atoms are 18
32+ 18= 50
There are 36 hydrogen 18x2= 36
Look at the numbers of atoms in the reactant and the product we will see we have the same amount for each atom
Balancing a chemical equation we need to make the reactant and product equal and balanced

Molarity of NaCl solution is 0.070 M .
To Find :
How many moles are present in the solution.
Solution :
Let, n be the number of moles.
We know, molarity is given by :
[tex]M = \dfrac{n}{V(in\ L)}[/tex]
So,
[tex]n = M \times V\\\\n = 0.070\times 2.5 \\\\n = 0.175\ moles[/tex]
Therefore, number of moles of NaCl is 0.175 moles.

1. You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer
A) conduction
B) convection
C) radiation
Answers
You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer, this represents conduction.
What is conduction?One of the three primary methods for the transfer of heat energy is conduction. Radiation and convection are the other two methods through which heat is transferred. Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide.
In liquids and solids where particles are more closely spaced, conduction happens more easily than in gases, wherein particles are more widely spaced. When there is a significant temperature differential between both the substances that are in contact, the rate of energy transfer through conduction is increased. You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer, this represents conduction.
Therefore, the correct option is option A.
