Answer:
as an anaerobic bacteria
Explanation:
These kind of bacteria do not need oxygen to survive, could it be that is a kind of facultative anaerobic bacteria, that means that sometimes they use oxygen for some processes and sometimes they do not need it.
Another possibility is that they are microaerophyls, that means, that they are going to use some oxygen to it metabolism but in a very small quantities.
Answer:
C
Explanation:
The rate of a reaction decreases as time progresses. ... If the amount of reactant particles is decreasing as the reaction progresses, then the chance of successful collisions must also decrease, and ultimately when all the reactant particles have reacted, the reaction must stop and the rate become zero.
Answer:
Mass of methane burnet 10.025 g.
Explanation:
Given data:
Mass of CO₂ produced = 27.5 g
Mass of methane burnet = ?
Solution:
Balanced chemical equation.
CH₄ + 2O₂ → CO₂ + 2H₂O
First of all we will calculate the number of moles of CO₂ produced.
Number of moles = mass/ molar mass
Number of moles = 27.5 g/ 44 g/mol
Number of moles = 0.625 mol
Now we will compare the moles of CO₂ with CH₄.
CO₂ : CH₄
1 : 1
0.625 : 0.625
0.625 moles of CH₄ are burnet.
Mass of methane burned:
Mass = number of moles × molar mass
Mass = 0.625 mol × 16.04 g/mol
Mass = 10.025 g
Answer:
Explanation:
Given the following mathematical expression;
A = ½(a + b)h
To make a the subject of formula (express a in terms of A, b and h);
First of all, we would cross-multiply;
2A = (a + b)h
Opening the bracket, we have;
2A = ah + bh
Rearranging the mathematical expression, we have;
ah = 2A - bh
