1) This type of energy transfer is called conduction.
2) Hydroelectricity
3) petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. All of these come out of oil refining process
Hope this helped and plz mark as brainliest!
Answer:
c) B, C
Explanation:
NaOH(aq) + HBr(aq) -----> NaBr(aq) +H2O(l)
1) concentration of acid CA= 0.05 M
Concentration of base CB= 0.1 M
Volume of acid VA= 25.00ml
Volume of base VB= unknown
Number of moles of acid NA= 1
Number of moles of base NB= 1
CAVA/CBVB = NA/NB
CAVANB =CBVBNA
VB= CAVANB/CB NB
VB= 0.05 × 25 × 1/ 0.1 ×1
VB= 12.5 ML
2.
Answer:
The two that are true are, "this represents a pure compound in two different states" and "it represents a mixture a solid and a gas".
Explanation:
This two are concluded only from the picture and the use of uniform colors throughout the picture (Showing the same element).
<span>Answer:
The rate equation for a nucleophilic substitution reaction of a tertiary reagent.</span>
Hello!
We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100g solution)
C: 70.79% = 70,79 g
H: 8.91% = 8.91 g
N: 4.59% = 4.59 g
O: 15.72% = 15.72 g
Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:
We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:
T<span>hus, the minimum or empirical formula found for the compound will be:
