1 ounces ----------- 29.5735 mL
5 ounces ----------- ??
5 x 29.5735 / 1 => 147.868 mL
hope this helps!
Answer: <em>The number placed in front of a compound to balance a chemical reaction is called </em><em><u>coefficient</u></em>.
Explanation:
Assume this general form for a <em>chemical equation</em>:
- <em>a</em>A + <em>b</em>B → <em>c</em>C + <em>d</em>D
The letters <em>a, b, c, </em>and <em>d,</em> in front of each compound A, B, C, and D, are called coefficients and indicate the number of formula units (molecules or ions) that take part in the equation.
Those coefficients are needed to <em>balance the equation</em> and ensure compliance with the law of mass conservation.
This example shows it:
- Word equation: hydrogen + oxygen yields water
- Chemical equation: H₂ (g) + O₂(g) → H₂O(g)
- Balance, adding the coefficients so that the number of each kind of atoms is the same on the left and the right of the chemical equation:
H₂ (g) + 2O₂(g) → 2H₂O(g)
In that equation:
- The coefficient of H₂ (g) on the left is 1 (it is not written)
- The coefficient of O₂(g) on the left is 2
- The coefficient of H₂O(g) on the right is 2
You read it as: 1 mole of gaseous hydrogen and 2 moles of gaseous oxygen yield 2 moles of water vapor.
Answer:
B) A series of chemical reactions where enzymes work one at a time to convert a reactant into intermediates and the intermediates into a final product.
Explanation:
In our cells there are multiple chemical reactions happening all the time to convert the elements we ingest (food, water, air) into the products the organism needs.
This processes can be very complex and offen involves various reactions (steps). Also, many of this reactions need to by catalized by enzymes in order to happen.
K= 8
C=4
O= 12
The number after the letter shows how much of that atom there is.
The 4 shows there is 4 of each after it, so 4 of the K2, C, and O3. You would want to multiply the K2, C, and O3 by 4.
