The answer is indeed carbon dating, but let me explain it to you a little bit better: This is so because Carbon dating is the method that has the determination of the age of an organic matter. That is why we can say that that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil. Hope this clarifies everything
Answer:
if my calculation are correct, it's 295 grams
Explanation:
because liters converted to grams is .1=100 so if you take 2.95 times 100, it equals 295
<span>To find the balanced molecular equation, we need to find the symbols for each element and their charges and then balanced the equation. This comes out to:
Al(OH)3(aq) + 3HBR(aq) ---> AlBr3(aq) + 3H2O(l)
The net ionic equation is adding the charges and separating them into basic components.
Al3+ + 3OH- + 3H+ + 3BR- --> Al3+ + 3Br + H3O+
We can cancel out the aluminum and bromine to get:
3OH-(aq) + 3H+(aq) --> 3H2O(l)</span>
So in a chemical change, the product would loses its properties, would form new products and would not be easily reversed.
In a physical change, the products WILL NOT lose any of their properties, WILL NOT form any new products and WILL be easily reversed.
Talking about Water turning to ice I would say it’s all about physical change and not chemical change.
But I would suggest you to either make a research about it or ask your teacher :))
AT, STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density
