Vanyuwa [196]3 years ago
5 0

Answer:

Possible lowest volume = 0.19 cm

Possible highest volume = 0.21 cm

Explanation:

Given Data

uncertainty  =  0.01 cm

total volume = 0.20 cm

Possible lowest volume = ?

Possible highest volume =  ?

Solution:

Possible lowest volume = total volume - uncertainty

Possible lowest volume = 0.20 cm - 0.01 cm

Possible lowest volume = 0.19 cm

Possible highest volume = total volume + uncertainty

Possible highest volume = 0.20 cm - 0.01 cm

Possible highest volume = 0.21 cm

When performing a flame test using the method described in the manual, you complete the flame test of KNO3 and find a yellow col
jolli1 [7]

Answer:

The nichrome wire is dirty.

The solution is contaminated.

Explanation:

If the nichrome wire is dirty, it may contain sodium contaminants which may be responsible for the yellow flame. The nichrome wire is first inserted into the flame without the sample to check for impurities.

The test solution may also have been contaminated. This leads to the appearance of a colour different from the expected colour of the test cation in the solution.

Solve for ‘x’: 12(x-7)+3(2x+2)=50x-2
Alex Ar [27]

Answer:

Explanation:

Hi there!

12(x-7) = 12x -84

3(2x+2) = 6x+6

Total 18x-78

18x-78 = 50x-2

-78= 32x-2

-76= 32x

19/8 =x

Hope you understand

Have a nice day,

Amino acids are the building blocks of proteins. The simplest amino acid is glycine (H2NCH2COOH). Draw a Lewis structure for gly
VashaNatasha [74]

Answer:

Explanation:

The lewis structure (indicating all the atoms and patterns provided as hint in the question) of glycine can be seen in the attachment below. While the chemical structure of glycine can be seen below

         H

          |

H₂N - C - C =O

          |      \

         H      OH

The structure (of glycine) above provides a "fair idea" of how the lewis structure will be.
