I don't quite understand the question your asking but iron is a metal and is appearance is silvery and greyish colour. Hoped this helped a little! : D
Answer:
A. 70.0 kpa
Explanation:
Given
Pressure = 525.4 torr
Required
Convert to kPa
From standard unit of conversion;
Multiply both sides by 525.4
<em>(Approximated)</em>
<em>From the list of given options, option A is the closest answer after 525.4 torr is converted to its kpa equivalent</em>
1.) Northern hemisphere
2.) Summer
3.) Winter
Answer:
2.95cm
Explanation:
Because 2.95 is right in the middle of 2.9cm and 3cm.
Answer:
0.00369 moles of HCl react with carbonate.
Explanation:
Number of moles of HCl present initially = moles = 0.00600 moles
Neutralization reaction (back titration):
According to above equation, 1 mol of NaOH reacts with 1 mol of 1 mol of HCl.
So, excess number of moles of HCl present = number of NaOH added for back titration = moles = 0.00231 moles
So, mole of HCl reacts with carbonate = (Number of moles of HCl present initially) - (excess number of moles of HCl present) = (0.00600 - 0.00231) moles = 0.00369 moles
Hence, 0.00369 moles of HCl react with carbonate.
