Answer:
B. 387 V
Explanation:
Ohm's law states that the voltage is the product of the current and resistance.
V = IR
V = (9 A) (43 Ω)
V = 387 V
Answer:
See below, please
Explanation:
Because the mole ratio
![\frac{m(ch4)}{m(o2)} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bm%28ch4%29%7D%7Bm%28o2%29%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Now, at the beginning
Mole m(CH4) =4 mol, m(O2) = 5 mol
If O2 gas is fully reacted, used up,
Need m(CH4) = 2.5 mol
Hence, the mole of CH4 left
m(CH4) = 4-2.5=1.5 mol
That means
At the end of the reaction,
m(CH4) =1.5 mol
m(O2) = 0 mol
Answer:
1.95 M
Explanation:
Molarity is a measure of the molar concentration of a substance (solution). In relation to the volume, it is calculated using the formula as follows;
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (L)
V2 = final volume (L)
According to the provided information in this question;
C1 = 14.38 M
C2 = ?
V1 = 1.28 L
V2 = 9.45 L
Using C1V1 = C2V2
14.38 × 1.28 = C2 × 9.45
18.4064 = 9.45 C2
C2 = 18.4064 ÷ 9.45
C2= 1.95 M
Answer:
There are 26 valence electrons in SOF₂.
Explanation:
Valence electrons are calculated by adding the valence electrons present in valence shell of each element present in SOF₂. So,
# of Valence e⁻s in S = 6
# of Valence e⁻s in O = 6
# of Valence e⁻s in F = 7
# of Valence e⁻s in F = 7
Now, add all valence electrons,
= 6 + 6 + 7 + 7
= 26 Valence Electrons
Answer:
O 9 carbon atoms, only
Explanation:
Prefix: non- simply means 9.
Suffix: -ene means double bond, -yne means triple bond, and -ane means single bonded carbons.
