Answer:
The friend is wrong. This chemical equation supports the Law of Conservation of Matter. The reactants are the same amount as the products.
Explanation:
In both sides of the equation, there is 1 Ca, 1 C, and 3 O. This means that this equation follows the Law of Conservation of Matter.
A thanks and/or good rating would be greatly appreciated :D
Answer: A
Explanation:
Oxygen makes up another 20 to 21 percent of our atmosphere. It's essential for life on Earth, and interestingly enough, it is poisonous when highly concentrated. Our concentration of 20 to 21 percent seems just right.
Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.
<h3>What are gamma rays and x-rays?</h3>
- Both of these are forms of ionizing radiation.
- Applying these to food is known as food irradiation.
- What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.
Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.
