Answer is: <span>water acts as a reactant.
Food is broken in series of reactions called catabolism. </span>Catabolism<span> is the group of </span>metabolic<span> pathways that breaks down </span>molecules of food (for example polysaccharides, lipids, proteins) into smaller units that are either oxidized to release energy or used in other anabolic reactions.
Water is used to brake bonds between large molecules.
Answer:
Four moles of water were produced from this reaction.
Explanation:
- The balanced equation for the mentioned reaction is:
<em>2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O,
</em>
It is clear that 2.0 moles of NaOH react with 1.0 moles of H₂SO₄ to produce 1.0 mole of Na₂SO₄ and 2.0 moles of H₂O.
<u><em>Using cross multiplication:</em></u>
2.0 moles of NaOH produce → 2.0 moles of H₂O.
∴ 4.0 moles of NaOH produce → 4.0 moles of H₂O.
<em><u>Using cross multiplication:</u></em>
2.0 moles of NaOH need → 1.0 mole of H₂SO₄.
∴ 4.0 moles of NaOH produce → 2.0 moles of H₂SO₄.
<em>Four moles of water were produced from this reaction. </em>
Answer:
6.696 g of water (H₂O)
Explanation:
First we calculate the number of moles of barium hydroxide:
number of moles = mass / molecular weight
number of moles = 31.8 / 171.3 = 0.186 moles of barium hydroxide
Form the chemical reaction we may devise the following reasoning:
if 1 mole of barium hydroxide produces 2 moles of water
then 0.186 moles of barium hydroxide produces X moles of water
X = (0.186 × 2) / 1 = 0.372 moles of water
mass = number of moles × molecular weight
mass of water = 0.372 × 18 = 6.696 g
Answer:
motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
Explanation:
Answer:
The electron configuration of magnesium is [Ne] 3s 2. It is an s block element, and it occurs as a solid at standard temperature and pressure. It is a shiny grey metal. The melting point and boiling points are 650 °C and 1091 °C respectively. The most common and stable oxidation state is +2, but it can form +1 oxidation state as well. In writing the electron configuration for Magnesium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.
