Answer:

Al₂O₃ + 6HNO₃ → 2Al(NO₃)₃ + 3H₂O

Explanation:

      left side of arrow      right side of arrow

Al               2                             1

O               3                             1

H                1                             2

NO₃           1                              3

Al₂O₃ + 6HNO₃ → 2Al(NO₃)₃ + 3H₂O

now there are,

      left side of arrow      right side of arrow

Al               2                             2

O                3                             3

H                6                            6

NO₃            6                            6

you have to try and multiply different numbers and stop when you have equal molecule  on both sides of the arrow.

Answer:

6HNO₃ ₊ Al₂O₃  ⇒  2Al(NO₃)₃ ₊ 3H₂O

Explanation:

HNO₃ ₊ Al₂O₃  ⇒  Al(NO₃)₃ ₊ H₂O

H=1                         Al=1  

N=1                         N=3

0=3                        0=9

AL=2                      H=2

O=3                        0=1            

6HNO₃ ₊ Al₂O₃  ⇒  2Al(NO₃)₃ ₊ 3H₂O  

H=6                          H=6

N=6                          N=6                

O=18                        O=18

Al=2                         Al=2

O=3                          O=3

Enzymes can be denatured unfolded by what environmental factors
erastova [34]

Enzymes can be denatured unfolded by heat or chemicals.

<h3>What are enzymes?</h3>

Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.

The factors that can denature enzymes include heat and chemicals. This is because:

  • Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.

  • These environmental factors can alter the pH level of the enzyme.

Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.
