When is the Law of Conservation of Mass not true? I am so confused...
Answers
Answer:
When one of the products of the equation is a gas. The gas escapes and isn't weighed and what is left is not the total mass of the system.
Explanation:
;)
Answer:
The conservation of mass does not apply if the system is open and energy escapes. However, it does continue to apply to totally closed/isolated systems. Therefore, if energy cannot escape a system then its mass cannot decrease.

any help is much appreciated <3
will reward brainliest to the correct answer (•◡•) !
Answers
Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

Aside from the tasks it performs, perhaps the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated. Also, circuit boards are less expensive than other options because they can be designed with digital design tools and manufactured in high volume using factory automation.

Etching helps us to see the structure of the atoms of copper.
What is etching?The term etching refers to the process by which we expose the inner structure of copper. It is usually done electrically or by the use of an acid. The surface of the copper is removed and the inner structure of the copper is shown.
As such, when you etch copper, you can see the inner structure such as the arrangement of the atoms of copper and how they fit together.
As such looking through the etched copper would help you to appreciate that matter is composed of atoms.

What is the importance of energy conversion in everyday life?As an example, food is consumed by humans to store potential chemical energy. When we walk or move in any way, as well as when we speak, we use this energy by converting it to usable kinetic and sound energy. We constantly produce heat energy as a waste, and when we work harder or are under more stress, this heat radiates from our bodies much more.
What does an energy conversion function?Energy transformations are operations that change one sort of energy (such as chemical, kinetic, or gravitational potential energy) into another. Energy transformation must be a part of every type of energy consumption.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
