Electrons might be the answer
Answer:
0.36 N
Explanation:
Let's consider the neutralization between HBr and NaOH.
HBr + NaOH → NaBr + H₂O
The equivalents of NaOH that reacted are:
24.0 × 10⁻³ L × 1.5 eq/L = 0.036 eq
Since the reactions are equivalent to equivalent, also 0.036 equivalents of HBr reacted.
The normality of HBr is:
N = 0.036 eq / 0.100 L = 0.36 N
Given reaction:
A + B ------ C + D
mass of A = 19 grams
Mass of B = 26 grams
Mass of C = 17 grams
To determine: The mass of D
Explanation:
As per the law of conservation of mass, in any chemical reaction the sum of masses of the reactants and products must remain unchanged.
Sum of masses of reactants = Sum of masses of products
19 g + 26 g = 17 g + D
Mass of D = (19+26) - 17 = 28 g
2 C4H8O + 11 O2 —> 8 CO2 + 8 H2O
Answer:
drive an electric car to work, walk to work, carpool to work
Explanation:
The orders of the activities from the greatest to least impact to reduce consumption of fossil fuels, is one in which the least fossil fuel is used;
- The goal of driving an electric car is to reduce dependence on fossil fuels.
- Electric cars prides as an automobile system with no carbon emission nor usage.
- Walking to work does not require carbon consumption too.
- Carpool involves use of fossil fuels.
