Answer:
2
Explanation:
There are 3 carbons on the right side
there are only two on the left side....you need one more ...so add one more... change the '1' coefficient in front of C to '2'
Answer:
volume = 0.288 L
Explanation:
To find the volume, you need to (1) convert grams LiBr to moles LiBr (via molar mass) and then (2) calculate volume (via molarity equation). It is important to arrange the ratios in a way tat allows for the cancellation of units (desired units in the numerator).
<u>(Step 1)</u>
Molar Mass (LiBr): 6.9410 g/mol + 79.904 g/mol
Molar Mass (LiBr): 86.845 g/mol
100 grams LiBr 1 mole
----------------------- x ------------------ = 1.15 moles LiBr
86.845 g
<u>(Step 2)</u>
Molarity (M) = moles / volume (L)
4 M = 1.15 moles / volume
(4 M) x volume = 1.15 moles
volume = 1.15 moles / 4 M
volume = 0.288 L
Answer:
Yes
Explanation:
The combination of an acid and base causes a chemical reaction. The product is a gas, bubbles that are carbon dioxide. The carbon dioxide gas is trapped in the balloon and it inflates. The carbon dioxide gas molecules created a pressure by colliding with the sides of the balloon.
Whenever I have tests like these, I make a quizlet with each part zoomed in and then answer it that way.
Answer:
Is A- Carbon Dioxide
Explanation:
other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface.
