Answer:
there are 3 significant figures
Explanation:
do not count the first 2 zeros. only the nimbers after the zero
Answer: 850.0 g/min.
Explanation:
- The rate of the reaction = (ΔC/Δt) where,
ΔC is the change in concentration of reactants or products.
Δt is the change in time of the reaction proceeding.
- The rate is needed to be calculated in (g/min).
- We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass).
- mass (g) = n x molar mass,
- n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol.
- m = 1.5 x 283.88 = 425.82 g.
- ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min.
- The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.
<em>can be approximated to 850.0 g/min.</em>
The answer is the first one because it’s a compound of two words separate when you say it :) hope this helps !
Answer:
The correct answer is product.
Explanation:
Hydrogen gas reacts with oxygen gas to generate water molecule.
2H2+O2 = 2H2O
We all know that that substances which are present at the left hand side of the equilibrium sign act as substrate and the substances those are present in the right hand side of the equilibrium sign are called products.
From that point of view it can be stated that water or H2O is the product of the reaction between hydrogen and oxygen.
Answer:
Nitrification is a biological process by which ammonia is oxidized to nitrites (
) and then to nitrates (
) by action of specialized bacteria in nature (such as <em>nitrosomonas</em> and <em>nitrobacter</em>).
Explanation:
This two-step process utilizes molecular atmospheric oxygen and ammonia and ammonium components of soil and nature.
<em>(a.) Ammonia and ammonium compounds to nitrite</em>
→ 
→ 
<em>(b.) Nitrite to nitrate</em>
→ 
<em>(c.) The reverse process involves reduction of nitrates to molecular nitrogen, called denitrification (with succinic acid in the equation below).</em>
→ 
(
and 
is an intermediate product in this process.)
