The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.
<h3>What is a Chemical reaction?</h3>
This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.
A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.
When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

Hey there!
To calculate the percent by mass of the Ca(NO₃)₂ we need to find the total mass first by adding.
896.92 + 22.63 = 919.55
In total, the solution is 919.55 grams.
To find the percent of Ca(NO₃)₂ in the solution, divide the mass of Ca(NO₃)₂ by the total mass and multiply by 100.
22.63 ÷ 919.55 = 0.0246
0.0246 x 100 = 2.46
Ca(NO₃)₂ makes up 2.46% of the solution.
Hope this helps!
Answer:
1.These results are accurate because the collected data is very close to the actual value.
4.These results are precise because all three trials are within a very close range.
Explanation:
Although in the ordinary language the terms precision and accuracy may be confused, in science those terms refer different properties of the measurements.
The accuracy is how close a measurement is to the true value, while the the precision refers to the reproducibility and repeatability, this is how the results show the same (close) value.
To differentiate precision and accuracy, It is very illustrative, to use the image of a throwing arrows to a target: if the arrows get close to the center of the target, then the results are accurate (close to the goal). If the arrows are not close to the cener of the target, but they are all close to each other, then the result is precise (the arrows land, approximately, in the same spot every time).
Answer:
Option C
Explanation:
The answer to this question will be the third option "It is bendable." Malleable means to be able to change the shape of a object without damaging or breaking it. In this case a malleable solid would be for example drainage pipes. These pipes have curves and different shapes but still remain its product of a metal.

X= How much.
x+.10×20=.25(x+20)
use this equation to solve
then plug answer back in to check if it's right
the answer should be 4ml.
