Answer: 2 C2H4 + 6 O2 => 4 CO2 + 4 H2O
Explanation:The coefficient are as follows: 2: 6: 4: 4
Each atom on the reactant and product side are equal.
Reactant Product
C 2x2 = 4 4x1 = 4
H 2x4 = 8 4x2 = 8
O 6x2 = 12 (4x2) + 4 = 12
Answer: True.
Explanation: A teakettle does have a greater frequency than a drumbeat. The teakettle has a higher pitched sound and frequency than a low pitched sound like a drumbeat. So a teakettle is high and a drumbeat is low.
The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.

Answer is: 116,1 g of Li₃N.
Chemical reaction: Li₃N + 3H₂O → 3LiOH + NH₃.
m(LiOH) = 240g.
n(LiOH) = m(LiOH) ÷ M(LiOH).
n(LiOH) = 240 g ÷ 24 g/mol = 10 mol.
from chemical reaction: n(LiOH) : n(Li₃N) = 3 : 1.
10 mol : n(Li₃N) = 3 : 1.
n(Li₃N) = 3,33 mol.
m(Li₃N) = n(Li₃N) · M(Li₃N)
m(Li₃N) = 3,33 mol · 34,85 g/mol = 116,1 g.
