B. 1, 1, 1, 2
Explanation:
You only need to balance the NaNO3 on the right. Since there is 2 NO3 on the left, you need to put a 2 in front of the NaNO3 on the right. Everything else is already balanced so the only coefficient needed is 2 in front of the NaNO3.
1 kg/L -------------- 0.001 kg/mL
22.4 kg/L --------- ??
22.4 x 0.001 / 1 => 0.0224 kg/mL
Answer:
A pregnant woman would consume 1.812 x 10⁻⁶ oz of mercury in a month if she ate the maximum recommended amount of fish.
Explanation:
0.302 oz mercury _____________ 1 x 10⁶ oz bluefish
x _____________ 6.00 oz bluefish
x = 1.812 x 10⁻⁶ oz mercury
A pregnant woman would consume 1.812 x 10⁻⁶ oz of mercury in a month if she ate the maximum recommended amount of fish.
Water, because electrolysis is using electricity to break the bond of water to release 2 Hydrogens and the 1 Oxygen.
The correct answer is option 4 and 5.
The electron domain geometry for an ammonia molecule, NH₃ has tetrahedral electron domain geometry. In NH₃ there are three bond pair electrons and one lone pair electron. Therefore, NH₃ has four electron pairs which are distributed in a tetrahedral shape.
The molecular geometry for an ammonia molecule, NH₃ is trigonal-pyramidal molecular geometry. Ammonia has one lone pair of electron and three bond pairs of electrons thus the resulting molecular geometry is trigonal-pyramidal.
