Answer:
The signs of chemical change include changes in color, temperature, the production of light, changes in odor, and the formation of gases.
Answer:
<h2>8.92 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4.75 g
volume = 0.5325 cm³
We have
We have the final answer as
<h3>8.92 g/cm³</h3>
Hope this helps you
Answer:
c solvents dissolve chemicals with the same polarity ( ex. both are polar)
Explanation:
Like dissolves like is one of the central rule that guides the solubility of one substance in another.
- It fully suggests substance having the same nature as in polarity-wise will dissolve one another.
- For example, water is a polar liquid, it will dissolve table salt because it i also polar.
- Water cannot dissolve oil because oil is non-polar.
Answer:
None of these are correct, because there is no way to balance this equation, but I hope these steps help you figure out your answer.
Explanation:
Count out the single amounts of elements you have on both sides of the equation. To be balanced, you need to have the exact same for each element.
Before balanced Left side.
Cl-2
O-8
H-2
Before balanced right side.
H-1
Cl-1
O-3
That means we need to increase Hydrogen, Chlorine and Oxygen on the right for sure and see how that affects the equation. You can keep adding the Coefficients until the # of elements begin to match on each side.
(I tried to balance this equation, it doesn't work, there is too much on the reactants side for what the product is.)
The formula for water is H2O so there would have to be two Hyrdogens and one oxygen. Therefore it would be 4g of Hydrogen and 16g of Oxygen leaving you with 20g.
The answer is D.
