The equation is not balanced because the number of atoms of Oxygen present in the reactants and product sides are not equal
The equation being referred to in the question can be written properly as
S + 3O₂ → SO₃
To determine whether the equation is balanced or not
We will check if the coefficient in the equation gives equal numbers of atoms for each element in the reactants and product
S = 1
O = 6
S = 1
O = 3
We can observe that, the coefficient does not give equal number of atoms for the element, Oxygen (O), in the reactants and product sides
∴ The equation is NOT balanced
Hence, the equation is not balanced because the number of atoms of Oxygen present in the reactants and product sides are not equal

Answer:
This equation is not balanced because you don't have the same amount of each element on each side of the chemical reaction. The balanced equation is:
2 S + 3 ⇒ 2
Explanation:
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by sub-index 2)
Right side: 1 sulfur S and 3 oxygen O (subindice value)
As you can see, you have the same amount of sulfur on both sides of the equation but the amount of oxygen is different. This indicates that the chemical equation is not balanced. To balance it, as the amount of sulfur is the same, the amount of oxygen must be balanced, which is different on each side of the reaction.
A simple way is to balance the equation is to multiply the product by 2, that is, add a coefficient 2 in front of the SO3 molecule, the reaction being as follows:
S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
The oxygen is now balanced, but the amount of sulfur on both sides of the reaction varies. To balance the quantities of sulfur, as now on the right side you have an amount of 2, you can add the coefficient to sulfur. The chemical equation is as follows:
2 S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 2 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
Finally you have the same amount of sulfur and oxygen on both sides of the reaction. So the chemical equation is finally balanced.
The amount of CO2 in the atmosphere has increased dramatically due to(mainly) excessive burning of fossil fuels.
Answer:
b. 80,000 units, because total energy remains unchanged
c. 20,000 units, because total energy of the skier decreases
d. 80,000 units, because total energy of the skier decreases
Answer:
30,000 units, because total energy remains unchanged.
Step-by-step explanation:
The law of conservation of energy states that energy cannot be destroyed, it remains conserved but transforms from one form to the other form.
Hence, we can say that
Total energy = kinetic energy (KE) + potential energy (PE).
At 100 meters above
Total energy = 0 + 50000 = 50000 units.
Hence, 60 meters, total energy would be
20,000 + x = 50000 units
Finally,
x = 50,000 - 20,000
= 30,000
The energy will only transform from one form to the other but will not change.

The total mass in a reaction is always conserved . Thus the total mass of reactants will be equal to the total mass of products. Hence f the total mass of the products of a reaction is 250 g, the total mass of the reactants is also 250g.
Mass conservation law is same as that of law of conservation of energy. That is, mass can neither be created nor be destroyed. Therefore, total mass of the system is conserved or it is a constant.
For any type of changes occurring for a substance, let it be a chemical change or physical change the total mass of the initial or original substance is gaines after the change from the new product or new state of the same substance.
Thus, no atoms created or lost in a reaction but they are regrouped to form new products. The new products are formed by bond making or bond breaking in the reactants their weight is completely transferred to the products.
Therefore, if a reaction is having total mass of 250 g in product side then it 250 g was the total mass in reactant side.

85 N to the right
85 N to the left
115 N to the right
115 N to the left
Answer:
A
Explanation:
Let's illustrate this; see the attachment.
We see that Mrs. Jacobson is pushing to the right with a force of 100 N and there is another opposite force pushing with a force of 15 N. Since these are in opposite directions, we can say that the force opposite to Mrs. Jacobson is pushing the fridge -15 N to the right (instead of 15 N to the left).
The net force would then be:
100 N + (-15 N) = 85 N to the right
The answer is A.
Answer:
85 N to the right
Explanation:
Convention: rightwards positive
Force applied by Mrs. Jacobson:
+100
Force applied by the fridge:
-15
Net force
+100 - 15
+85
