Answer:
When n acid reacts with a base , salt and water is formed because when acid reacts with base, it loses its acidic property and base loses its basic property to form a neutral substance like salt and water..
Answer:
17.04%
Explanation:
Actual Value = 173.1
Measured Value = 143.6
Percent error is obtained using the equation;
Percent error = (Measured - Actual) / Actual ]* 100
Percent error = [ (143.6 - 173.1) / 173.1 ] * 100
The absolute value of (Measured - Actual) is taken,
Percent Error = [29.5 / 173.1 ] * 100
Percent Error = 0.1704 * 100 = 17.04%
Heterogenous mixtures can separates due to differences in size of components
The given complex Ion is,
[Co(CN)₃]³⁻
In complex compounds the Positive part is named first, followed by name of Negative part. In given case there is no Positive part. So, we will name the Negative part.
In Sphere the Ligands are named first. In this case there are 6 CN⁻ ligands. As CN⁻ (cyanide) contains a negative charge so the -ide is replaced by -o. i.e. Cyanide → Cyano. Also, Hexa is placed before Cyano as there are 6 CN⁻ Ligands.
So,
Hexacyano
After that Chromium metal is named. As there is a negative charge on the sphere, so the -ium in Chromium is replaced by -ate.
i.e. Chromium → Chromate. And the oxidation state of Cr is written in Roman. Hence,the name is as,
Hexacyanochromate (III) Ion
Answer:
They are called downbursts.
