Lithium atoms contain 3 protons, 3 electrons, and 4 neutrons, so the statement is Correct
Explanation:
When designing and conducting a scientific experiment then it is necessary to sequentially follows all the steps necessary for the experiment.
Also, it is required to identify independent variables, if any. On the other hand, it is required to address any confounding variables, so that it becomes mentioned the type or number of variables present.
Thus, we can conclude that when designing and conducting a scientific experiment:
- Identify the independent variable.
- Address any confounding variables.
C) The bonding between carbon atoms allows for branches in carbon chains.

Write and equation: H₂SO₄ + 2KOH ===> K₂SO₄ + 2H₂O
find moles of the known (KOH): <span>Moles = volume x moles / 1000
moles = 22</span>.87 x 0.158 / 1000 = 0.00361346
use ratio 2:1 so the moles of H₂SO₄ is 0.00361346 / 2 = <span>0.00180673
</span>
now use equation: Conc. = moles x 1000 / volume
Conc. = 0.00180673 x 1000 / 20 = <span>0.00180673moldm</span>⁻¹
