Take a zip lock bag and draw clouds on the outside with a sharpie then fill the bag with water and then tape it on a window that has a lot of sun and wait awhile and there should be a change in the water and that shooed what happens to water when it’s warm/sunny out
Answer:
Explanation:
moles of acetic acid = 500 x 10⁻³ x .1 M
= 5 X 10⁻³ M
.005 M
Moles of NaOH = .1 M
Moles of sodium acetate formed = .005 M
Moles of NaOH left = .095 M
pOH = 4.8 + log .005 / .095
= 4.8 -1.27875
= 3.52125
pH = 14 - 3.52125
= 10.48
Answer:
The sum of the coefficients in the balanced equation is 11
Explanation:
A reaction where an organic compound reacts with oxygen to produce carbon dioxide and water is called combustion.
The balance reaction of combustion for methanol is:
2CH₃OH (l) + 3O₂(g) → 2CO₂(g) + 4H₂O (g)
Coefficients from stoichiometry are 2, 3, 2 and 4
Sum = 2 + 3 + 2 + 4 = 11
<u>Answer:</u>
<em>Burning gas on a stove top transforms chemical energy into thermal energy.</em>
<u>Explanation:</u>
Cooking food involves in two types of energies. <em>They are chemical energy and thermal energy.
</em>
We use gas for a gas stove.Here gas is chemical energy.when we light the stove the fire lits up and here the <em>chemical energy energy is converted into thermal energy.</em>
Breaking and combining of bonds during combustion gives heat and light.This thermal energy heats the vessels and cooks the food through the <em>process of conduction, convection and radiation.
</em>
