Answer:
.24 mg
Explanation:
The mineral contains .016 % silicon
mass of the mineral = 1.5 kg
mass of silicon = 1.5 x .016 %
= 1.5 x .016 / 100
= 24 x 10⁻⁵ kg
= 24 x 10⁻² mg
= .24 mg .
Atoms of the element beryllium would most likely behave similar to the way d lithium behaves
Answer:
Cells can only be formed by division of pre-existing cells. [Students should be aware that the 64 codons in the genetic code have the same meanings in nearly all organisms, but that there are some minor variations that are likely to have accrued since the common origin of life on Earth
Explanation:
The NaOH will be used What titrant to titrate the 0. 02 m hcl phenol red solution.
Acid-base titrations may be the most typical titrations, although there are numerous more forms as well. Take a look at this illustration where sodium hydroxide is used to titrate a sample of hydrochloric acid (HCl) (NaOH). The titrant (NaOH), which is added gradually throughout the duration of the titration, has been added to the unknown solution.
Titrants are solutions with known concentrations that are added to solutions whose concentrations must be determined. The solution for whom the concentration needs to be determined is known as a titrant as well as analyte.
Therefore, the NaOH will be used as a titrant to titrate the 0. 02 m hcl phenol red solution.
